Singularity Utopia5,944I've noticed some people doing #sharedcircles recently on G+, which was a handy thing when I first started using G+, thus for newcomers here is my contribution. This circle includes a mixture of people and pages. The general theme is science, technology, thinkers; people who may have a #Singularity interest.2015-04-09 10:20:04273000

curator Circle0As promised yesterday, here is the #CuratorCircleEdition  4Wisdom of this circle: Take time to view the profile of those you add if you care for the quality of the content shared on G+!Some of you that show interest to be included in the circle will not find themselves in. It is not an hazard; the minimum one can do while asking for inclusion in a shared circle is to include the sharer page or profile. Also due to the maximum space of 500 profiles, others have been kept for the next circle.Rules of the circle:1. Plus and share the circle (add me if you haven't done it yet)2. Comment to ask for inclusion. And enjoy your day.2014-05-06 13:53:46501351023

David Carver401Alright, thought I'd share my "Everyday" circle.  This contains people that use G+ frequently.  It is has a wide variety of topics, and content.  It is a grab bag full of posts and people I find interesting.  Some post pretty frequently, others post less often.Topics cover tech, video games, food and drink, beer, adult material, and much more.  Many people here have graduated from my "Following" circle to my "Everyday" circle, which is my top circle.  If you are here.  Congrats.  You only have down wards to go. :)2012-11-19 21:46:36157404
Yvan Da Silva4,840Hi everyone,As many of you already know, I have a nice circle called "ReadThis", the name says it all. From time to time I go check what that circle is doing because I know they do great posts, have absolutely brilliant minds and have caught my attention at a moment or another.You don't have to do anything special to get in, this circle is in constant movement. People get in, some people get out etc. Depending on their posts, comments and activity. If you are new to Google+ then this is definitively a circle you might consider. You do not have to add them all, you can actually select which people you want to follow! Hope it will help you find great people.Happy Friday everyone ! #followfriday   #followfridaycircle   #sharedcircles   #sharedpubliccircles   #circleshare   #circlesharing  2012-11-09 16:53:45199303

So, I made noises some time ago about how I don't want another 2.6.39 where the numbers are big enough that you can't really distinguish them.

We're slowly getting up there again, with 3.20 being imminent, and I'm once more close to running out of fingers and toes.

I was making noises about just moving to 4.0 some time ago. But let's see what people think.

So - continue with v3.20, because bigger numbers are sexy, or just move to v4.0 and reset the numbers to something smaller?

You people on the East coast think you have it bad, with snow-storms and whatever.

That's nothing. My coffee maker broke, and calling the service hotline says "we're not open today due to inclement weather".

You guys get a little snow, and suddenly civilization breaks down.

My coffee maker is broken and nobody is answering the phone.

And CNN just keeps talking about snow. What about my coffee? Priorities, people, priorities.

What am I going to do without my coffee maker? I'm going to sit here in a corner, crying, that's what.

I'm not a fan of traditional AI (rule building and LISP/prolog etc), but am just waiting for neural nets to take over. 

This is a great example, and training on the Linux kernel sources just explains so much.

Sigh.

This is wonderful; neural network setup producing wonderful results; one example is training it on wikipedia and it ends up producing valid XML pseudo articles.  Another is training it on Linux kernel source, and it ends up producing C code that looks appealingly complex until you try and figure it out (even with bogus comments).

I've lived in the US for over eighteen years now, and it took me that long to realize that bitter lemon is just tonic water with lemon juice.

Seriously, how could I not have realized? Every time I flew to Europe or Australia, one of the highlights would be how I could finally find bitter lemon again. I would binge on the stuff, because I knew that when I got back to the US I wouldn't be able to find it any more.

No more. I always have lemon juice in the fridge anyway (not the disgusting stuff in plastic bottles: Santa Cruz organic lemon juice actually tastes like lemons). So now I can just buy tonic water when I get the craving.

So I think this talk is interesting (well, if you're a kernel developer) for a couple of reasons.

First off, I just like how Arnd says that I take everything they send me these days.  It's true, and it's a good thing. The ARM situation has just improved tremendously over the last several years. It used to be a major pain to me, it has gone to almost being entirely painless.

The other (somewhat related) point is how this is a talk about a big subsystem that has both an upstream and a downstream, and talks about keeping upstream happy - with a part being about keeping me happy, but most of it being about keeping the ARM SoC maintainers happy.

And they end up being similar issues, and related to the above point. Arnd talks about how the most stressful part is the pull request you reject - or come close to rejecting. And yes, I'm really happy that ARMh... more »

One of the two presentations I did at ELC 2015 is now available as video. Slides have been public for a while already at http://elinux.org/images/f/f7/Maintaining_a_Large_Kernel_Subsystem.pdf

The other presentation was scheduled at short notice, maybe the video got lost on the way.___So I think this talk is interesting (well, if you're a kernel developer) for a couple of reasons.

Arnd talks about how the most stressful part is the pull request you reject - or come close to rejecting. And yes, I'm really happy that ARM has gone from that "reject or come close to rejecting" state to that "Linus just puills everything we send him". Because yes, it really is a lot less strssful.

And finally - Arnd may have a picture of me flipping a finger, but then he talks about problems he has had with submaintainers. I guess he didn't want an "Arnd flipping the finger" picture to become as widely spread as the one of me. But yes, the problems he mentions are very much problems I have had too and that make me grumpy, so I think my finger is not irrelevant.

That in itself is, I think, important. The way we've handled scaling of development is by having multiple layers of maintainership. And the thing that really helped with ARM in particular (and x86 before it) was to have the submaintainers really be not just funnels to me, but do exactly what I do.

I think it's good to see how being a maintainer in the middle isn't really any different from being a maintainer at the top.

+Jon "maddog" Hall points out that today is the 21st anniversary of one of my early public talks about Linux (at DECUS in New Orleans). That trip (and maddog in particular) ended up then resulting in Linux being ported to the alpha, which is where we got the multi-architecture portability from.

(Yes, there was the earlier m68k port, but that one wasn't trying to actually support multiple architectures side-by-side from the same code base).

How time flies.

Both my tablet and my phone suddenly and for no obvious reason stopped syncing email for me yesterday. And after 24 hours of more or less being useless to me, the only way I could fix it was to completely remove my google account from the device, and then add it back in.

Which causes the phone/tablet to pretty much act as if you switched phone hardware (although app data doesn't go away). So it re-installs all the apps I had deleted (it's "backup", you know), and causes all my pinned music to go away and need to be re-downloaded.  Etc etc stupid small annoyances.

Am I the only one this happened to? It's not like it was a huge annoyance (ok, it was, but mainly because I spent 24 hours waiting for google to "fix" sync, until I just gave up blew my account away and signed in from scratch).

But I do have a request for the +Android team as a result of it: can you make things like managing your music (and apps, but that's actually less painful) on the device be something you could do from somewhere else?

I've had this issue before when switching phones: it's just a pain to pin your music on the device (and yes, I really do want to pin it, and not stream over the data connection all the time).

I'd really prefer to manage my phone remotely from a big screen and with a good mouse and keyboard, rather than fat-fingering it directly..___

Ever wonder about the habits of kernel developers? Who is a night-owl, and who has a 9-5 job? Who has kids?

Never fear, you can just ask 'git' (let's see how badly G+ screws up the formatting here - there seems to be no "block quote" formatting thing):

    git log --merges --committer=Torvalds --pretty="%cd" v3.19.. |
        cut -d' ' -f4 | cut -d: -f1 |
        sort -n |
        uniq -c

and there it is.

Now, look out a bit: my merge history says that I'm more active in the mornings, then take a breather around noon (recently that's my swimming) and then come back in the afternoon.

But if you skip the "--merges", it looks very different, and it looks like I do most of my commits in the afternoon, then take a break for dinner, and come back after 9pm.

But if you skip the "--merges", it looks very different, and it looks like I do most of my commits in the afternoon, then take a break for dinner, and come back after 9pm.

Why? My non-merge commits are hugely skewed by the patch-bombs from Andrew, which seem to happen in the afternoon. While a fair amount of my merge activity in the morning is because of all the pull requests that came in overnight from other parts of the globe.

Also note that the best statistics really depend on committer times, since author dates are often skewed by who forwards the emails and where in that sequence people added a date to it. So I wouldn't trust author dates to show the authorship dates as much - they might instead be showing the email patterns of people in the chain.

I'm sure you could make something cute with gnuplot and show different patterns of the top developers.

And if you're a developer and don't want the world to see how you seldom get up before noon, you might want to be aware of just how much these things can tell people about your work habits.. Although among sw people, I suspect the "not up before noon" is a badge of honor (as well as a indication that you don't have kids ;)

Any watch geeks out there?

I'm looking for a replacement for my Skagen 817LBXC that I really liked, but the ceramic band ended up being too brittle.

My simple requirements are apparently a bit too simple for most watches:

 - Last forever (years). No winding. Something like Citizen's Eco-Drive is great, but I guess I can get a battery changed if it only happens every three years or so.

 - Thin, with a good metal band and buckle. We're talking 5-8mm case thickness.

 - Tasteful and "not shiny". So no polished stainless steel. But darkened steel, or just matte titanium, or whatever.

 - Show the time. Legibly. Nothing else matters.

An example of something that comes so close that it almost hurts is the Citizen "Stiletto". Except for that last point. The whole "black on black"thi... more »

An example of something that comes so close that it almost hurts is the Citizen "Stiletto". Except for that last point. The whole "black on black" thing is too cool for me, but more importantly, it means that the watch doesn't actually work as a watch. 

That thing would be beautiful with bright orange (or green) arms. They'd be an interesting accent on a beautiful watch, and would make it actually work as a watch. But no. Some emo designer person decided that black-on-black is too cool for words.

Anybody? And I'm serious about the "thin and tasteful". Minimalistic. Tell the time, don't play games.

It can't be that hard, can it? But I'm not having much luck finding anything.___

I love +Amazon.com (I have already mentioned it before as the reason I often don't have to get out of my ratty bathrobe for weeks at a time), but christ people, you just really screwed up.

I got a defective remote control for my steam shower (yeah, yeah, I understand that my Finnish citizenship is in danger by admitting this, but I have to say I almost prefer the steam shower over the real - albeit electric - sauna we also have).

So I returned it, with a nice write-up about what was wrong with it both inside and outside the box. Just to make sure that people realized it doesn't actually work. But I still wanted the remote (so that I can start the steam and let it heat up for a while before actually going into the shower) so I just asked Amazon to replace it.

But I still wanted the remote (so that I can start the steam and let it heat up for a while before actually going into the shower) so I just asked Amazon to replace it.

The replacement came today. It was an opened box, which made me a bit nervous. I hooked it up, and it showed the same broken behavior as the previous unit. Hmm.

I hadn't actually marked the box any way, or written up serial numbers, and I'd returned the previous unit in pristine condition, but I had changed the battery in the remote unit as part of my "let's make sure it really is broken before I send it back" routine.

Yeah, the "replacement" unit had my replacement battery in it (and the same unglued magnet in the battery compartment, but maybe they just use bad glue and that's not unusual). And I'm pretty sure it's my replacement - since we don't throw batteries in the garbage, I could actually find the old CR2032, just to double-check that my IKEA-sourced replacement was different from the ones they use in the original.

Now, +Amazon.com, I understand that people probably return things as "broken" all the time because they are morons, and they bought the wrong thing and it's just easier to say "it's broken" than "I'm a f*cking moron" on the return slip.

So I can understand that you try to send the allegedly broken merchandise to the next customer, because it's a numbers game, and it's probably a good idea to just double-check. Really, I understand. I'd do the same thing. We're all morons. I get it.

But sending it back to the same customer? Yeah, that's not so smart. I guess most of the stuff you work with is high-volume enough that there is no point in tracking this thing (what are the odds?), but clearly when you only had one in stock, you might want to re-think your strategy.___

Congratulations all around.

Congratulations to Daniela, who placed second over-all in her gymnastics group (level 9 Sr) at the Oregon State Optional Championships last weekend.

Congratulations to Patricia, who no longer needs to worry about whether she got accepted to college, and instead has to worry about which college to go to. Cornell? Johns Hopkins? Duke? RPI? Smith? Vanderbilt?

And congratulations to me.  I have now been swimming for an hour every weekday for the last six weeks. That's 30h in the water, about 45-50 laps per hour. If I did my math right, that's about 40 miles of swimming (or "controlled not-drowning" as I like to call it when I splash around).

Never ask an expert for advice.

As I'm sure surprises nobody at all, I'm a gadget person. And while it shouldn't surprise anybody, but maybe does, I also end up cooking dinner for the family quite often. Put the two together, and what do you get? 

Right. A kitchen filled with random gizmos. Some more successful than others. The breadmaker? Not one of my shining moments. The shave ice maker, though? Quite popular.

Anyway.

The newest addition to the kitchen is a sous vide cooker. That's some serious chef stuff (which I am not - I cook food, but the children complain - until I remind them that they could do it themselves - that we don't really do a lot of different dishes).

But hey, the new Anova was really quite cheap and is dead easy to use. And unlike a lot of kitchen gadgets it also has the advantage of being rather small,... more »

But hey, the new Anova was really quite cheap and is dead easy to use. And unlike a lot of kitchen gadgets it also has the advantage of being rather small, so if/when it ends up not being one of the useful gadgets, it hides quite well in a cupboard. Because you know how some other gadgets sit there in the open, publicly shaming you every day and going "Remember me? You could do something awesome with me?"

cough-damn-breadmaker-cough.

So I made some steaks with them, and I was really very happy. I really like good meat, but I'm not great at it, and it often doesn't fit our schedule: the kids are off doing something, and Daniela in particular often comes home fairly late from gymnastics, so either she eats separately or I have to get the timing just right etc. 

And it turns out that this really gets to be a no-brainer with sous vide. Daniela not home yet? No problem. Leave one of the steaks in the water bath, it's two minutes to sear it whenever she gets home. 

But I'm smart (NOT!), and remembered that +Jim Zemlin was talking about sous vide back before sous vide was cool. He's quite hipster like that. So I thought I'd ask him for suggestions. 

Which gets us back to the beginning. Never ask an expert for advice.

Because now I feel like a complete redneck. I'm the trailer trash of sous vide. Jim sent me suggestions that made my eyes water. And when I explained that was wasn't quite what I had in mind, he toned it down and sent me a simple recipe, talking to me in baby-talk. It still had more ingredients than most things I make, and that was just for the rub.

Now the pressure is on.  I'll have to go out get a vacuum sealer, instead of just using zip-lock bags like some kind of caveman. I think I could hear Jim shudder over email when I described my white trash sous vide setup.

I really hope the vacuum sealer won't look at me accusingly. "Think of all the awesome things you could do with me".

I will have to buy a small one.___

Another update on my Ubiquiti UniFi network, since I today noticed another device that wouldn't connect to it..

The UniFi UAP's in zero-handoff mode apparently only does 802.11gn. Which sounded OK to me, since it's 2015, and who would be crazy enough to do 802.11b in this day and age? That's just so "last century" after all. I'm a gadget guy, I don't do old hardware.

And for a while there, I thought I had no problems. The kernel slow authentication packets patch got merged and is getting backported to stable, and all our devices seemed happy.

Until...

Today we talked about the odd WiFi scale we have, and I told Tove that it's not syncing because it's still trying to connect to the old network that I got rid of. Obviously I then had to fix that. And the damn thing just wouldn't connect to the new one.

Some googling seemed to show that I needed to enable legacy device support on the UniFi AP's. Which also meant that I had to disable ZH. Arghh

Oh well. The system seems to work OK now, and in the meantime I've grown to appreciate the ability to manage multiple AP's as a group, despite the oddish Java controller setup. So I'm off zero handoff, but still using the UniFi APs.

A bit of a bummer, but getting rid of the stupid WiFi scale was apparently not an option.___

Interesting. I just did my weekly "spam inspection" (ok, I lie: I try to do it weekly, but sometimes I just delete it all without having the energy to look through it).

And either spammers are using snippets of technical emails (I've seen that), and that is breaking the gmail bayesian filters for real technical emails, or Google really has something against +Mark Brown.

Congratulations are in order to the Google Lollipop Calendar team.

Guys, you looked immensely stupid there for a while. But today I got a calendar update, and the weeks are seven days again, and pinch-to-zoom works again.

I congratulate you on getting off the bad drugs, and not looking quite as f*cking stupid as you did there for several months.___

I'm either a genius or a moron. I can't quite decide which. I guess time will tell.

I obviously work in front of the computer the whole day, and it's not healthy. I tried the zombie shuffling desk, but after a couple months of walking, I got plantar fasciitis and had to take a break. And while I was proud of doing it while I did it and knew I needed to, it was never really something I enjoyed doing.

In fact, I've never found an activity that I like doing. I know people who run, and get that "runner's high", and they try to explain that I must be doing things wrong. 

The one exception is swimming. I actually like swimming, and while I'm only slightly faster than a snail (yes, I googled "worlds fastest snail" just to make sure - I can take on any snail and win, dammit), I actually like it. And there's a pool just a mile... more »

But parking there is just not worth the hassle, and while I've tried biking there, when I did that I noticed that I just absolutely dreaded the ride back. There was no way I was going to enjoy swimming for an hour without constantly knowing that after I'm done, I then have to bike back in our hilly neighborhood.

I know, a mile and a half is nothing, but several years ago I did it a few times and just stopped.  It wasn't going to happen. I wanted to swim, not ride my bike.

My trial solution right now? To try to get in shape (or rather, not get in worse shape)? 

An electric bike.

So yeah. My solution to try to get in shape is to get a bike that I don't need to pedal.

That's really some "special" genius right there.___

The Eurovision contest isn't until May, but Finland is already getting into the news.  As usual, it's not because anybody thinks Finland will win (after all, they changed the voting rules after the one time Finland did win), but because the Finnish entry is a bit unusual.

As always.

I enjoyed(*) watching some of the other historical Finnish entrants.

(*) And by "enjoyed" I obviously mean "cringed".

Lazyweb update..

I've got a couple of days of actual results now, so maybe people want to get some early feedback on my attempt to get a virtual wireless network that looks like a single AP to clients, while having multiple APs to get better coverage.

So the reason I'm doing this is that we have this kind of rambling house, with my office above the garage, and just having a single AP has never worked very well for it. I've tried several different setups with multiple AP's, but they just haven't worked all that wonderfully. I ended up having reasonable behavior with having identical APs, but I still find that clients connect to the wrong one, and other clients get confused by having the same SSID with multiple APs and just connect to the first one they see.

And I appreciate the comments from people, but when looking at prices and availability, it was... more »

I've tried several different setups with multiple AP's, but they just haven't worked all that wonderfully. I ended up having reasonable behavior with having identical APs, but I still find that clients connect to the wrong one, and other clients get confused by having the same SSID with multiple APs and just connect to the first one they see.

And I appreciate the comments from people, but when looking at prices and availability, it was really a no-brainer. The Ubiquiti single-band UAP runs at about $60 a pop, so you can buy a three-pack off Amazon for $180. The other "commercial grade" APs that do this seem to be in the $800 range. For a single AP.

So with that no-brainer, I now have a UniFi zero-handoff network  at home. And as people told me, you really don't need to run the Java controller thing except for setup. Which isn't that big of a deal.

It all seems to work fairly well, except for the fact that the UniFi APs are apparently quite picky at authentication time, and really don't like clients that optimistically connect using authentication packets at high data rates. Which the Linux 802.11 layer does by default. 

So I'm blaming the UniFi AP for being fairly fragile at connection time. Tssk, tssk.

I have a patch to make Linux just connect at slower rates, and that makes it work well. That patch is almost certainly a good idea in general, and some drivers (like the intel iwlwifi one) already did it on their own because apparently driver writers had found other picky APs.

So I hope/expect it will be merged by the networking people soonish, but it is a black mark against the UniFi AP.

That said, $60 vs $800? Yeah, I think I can live with it.___

Lazyweb time..

Is anybody aware of zero-handoff wifi APs that just work? I know of Ubiquity UniFi, and I dislike how it needs to run that java-based controller with an open port. I don't want to set up something like that on my regular machine, but that machine gets re-installed, re-booted, and just generally does random things.

So with ubiquity, I'd probably need to set up some random other machine just for the controller. Which just seems a stupid hassle. Why they don't just sell a controller box (I'm sure a RPI could do it) escapes me.

And no, I don't want a cloud controller either. 

And don't tell me about automatic client hand-off. I have that. It's what I want to get away from.

[ Update: I'm trying UniFi without the controller, and it seems to work. One of my laptops doesn't like the UniFi network, but that one... more »

So, I made noises some time ago about how I don't want another 2.6.39 where the numbers are big enough that you can't really distinguish them.

We're slowly getting up there again, with 3.20 being imminent, and I'm once more close to running out of fingers and toes.

I was making noises about just moving to 4.0 some time ago. But let's see what people think.

So - continue with v3.20, because bigger numbers are sexy, or just move to v4.0 and reset the numbers to something smaller?

Oh, how I loathe thee right now, +Intuit.

Tax season is approaching in the US, and I thought I'd use TurboTax once more because it actually worked very well for me last year. I admit I wasn't thrilled about it, because the company is famous not just for TurboTax, but for its sleazy politics and paying politicians to screw up making tax prep easier.

But it's definitely a service I'm willing to pay for, and I appreciate the simplicity. 

Or rather, I used to appreciate the simplicity.

This year was supposed to be even simpler than last time, since I could just use my previous year and import the data rather than type it in.

And it started out well - not only did it have my old information, but this year my W-2 got imported without me having to even type it in. I don't think that was true last year. Yay, progress!

And it started out well - not only did it have my old information, but this year my W-2 got imported without me having to even type it in. I don't think that was true last year. Yay, progress!

My taxes are actually fairly simple, and it probably wouldn't be that painful to do them by hand, but that's the kind of convenience that actually makes me think the service is worth paying for.

And then..

Today I got the final missing piece of tax information: my 1099-MISC for the royalties for my book "Just for Fun". They are not really all that noticeable, but hey, the IRS wants to know about them, and what the IRS wants, the IRS gets. They say "Jump", I say "How high?". And it was the last remaining information, so I got back to finalize my tax return.

Last year, that royalty thing meant I had to use "TurboTax Premier", this year it apparently means "TurboTax Home & Business". I actually knew about that (since I read the news), but I wasn't too worried, because the news had also said that +Intuit had apologized because of the outcry, and that there was a rebate.

And to be honest, I didn't even care that much, because I used to pay more to just have somebody else handle it for me. Tax season is not famous for being a happy time, and I'm willing to pay a bit to lessen the pain.

But it turns out that extra cost of the upgrade wasn't the annoying part. Maybe I hadn't read the news about the TurboTax outcry sufficiently well...

The annoying part about the "upgrade" is that it also made the whole stupid single 1099-MISC form go from "just enter the information" to a rather painful experience.

Because you now have to use the "Home & Business" version, TurboTax wants fill in the idiotic "Business" forms that weren't actually useful. And when I made the mistake to decide to see if I could avoid that somehow and went back, it had already created some kind of zombie 1099-MISC entry that it took me longer to find and delete than was really called for.

The "one minute to fill in a 1099-MISC entry that had all the payer information already filled from last year" turned into an hour of trying to figure out what the heck TurboTax was unhappy about, and then extra time to just walk through the end result several times.

+Intuit - I'd have been fine with paying more. I even expected it, although I was admittedly hoping that there would be a rebate because others had complained.

But what I didn't expect was that your money-grabbing play would not just be about the higher cost, but also be a hell of an inconvenience.

And remember: the only reason to pay you guys in the first place is the convenience, so "hell of an inconvenience" is a big big red mark for you.

Remind me again why I should bother with you guys next year? Paying more for getting worse service? Sure, I see what's in it for you. I just don't see what's in it for your customers.___

Here's an update on the coffee situation, because I know you've all been worried about this disaster. 

I thank people for their support in these difficult times, although I have to wonder about the kind of people who suggested using boiling water, socks and coffee grounds. I realize some people seem to drink coffee the way if comes on airplanes, but really... Let's all raise our expectations a bit. Plus, if that was the kind of coffee machine that had broken, I'd not have had to call the East coast to get it sorted out, now would I?

As others figured out, I've had a Jura superautomatic for almost fifteen years now. Not the same machine for all that time - I'm on my second one, because the first one started breaking after ten years of valiant service.

As others figured out, I've had a Jura superautomatic for almost fifteen years now. Not the same machine for all that time - I'm on my second one, because the first one started breaking after ten years of valiant service.

Because while I'd like to tell you that I grow and grind my own coffee and use a manual press to get the required 10+ bar of water pressure, but I'd be lying.

I enjoy the concept of being super-serious about my coffee, and roasting my own beans, and grinding them, and just being very hands-on, but at the same time, the last thing I want to do when I'm bleary-eyed in the morning is to do anything that requires hand-eye coordination and any amount of concentration. So no, the kind of coffee machine I have, I press a button, and magic happens, and it grinds the beans for me, tamps it, extracts the coffee, froths the milk, and makes me a decent latte without me having to actually ever open my eyes.

Anyway, the Jura service center is apparently in Pennsylvania, and it seems that CNN was making a bit more of the East coast trouble than was really appropriate (no, really? I'm shocked). Because while the service center -or at least the service call part - was closed due to inclement weather on Monday, on Tuesday things were up and running again, on Wednesday I had my UPS shipping label, and today I got notified that the coffee maker arrived, got fixed, and should be on its way back.

Quite impressive turnaround +JURA. Despite the apparent collapse of civilization on Monday.

But I have learnt my lesson. I now have a backup. It's not fully automatic, and I have to actually wake up enough to grind and tamp my coffee and froth my milk myself, but I am making do and feeling very Robinson Crusoe about it all.

And am now ready for the next coffeegeddon. ___

You people on the East coast think you have it bad, with snow-storms and whatever.

That's nothing. My coffee maker broke, and calling the service hotline says "we're not open today due to inclement weather".

You guys get a little snow, and suddenly civilization breaks down.

My coffee maker is broken and nobody is answering the phone.

And CNN just keeps talking about snow. What about my coffee? Priorities, people, priorities.

What am I going to do without my coffee maker? I'm going to sit here in a corner, crying, that's what.

Underwater pictures.

I had a camera with me too, and actually used it on E-6 (a dive site so named apparently because of the huge amounts of film used on it, and the process used to develop said film).

But I'm not sure I even want to take a peek at the results, because as usual, it's going to be full of just blurry fish butt.

So my plan is to instead take credit for all the photos +Dirk Hohndel​ took. Because that whole "make use of other people's work" worked so well with source code, why not do that in photography too?

I feel very managerial.

The merge window being over, and things being calm made me think I should try upgrading to F21..

Not the smoothest upgrade ever, but it's not too painful either. Here are my quick notes to make it come out right:

The yum upgrade instructions suggested finishing off the install by installing "system-release-workstation", but that did nothing but conflict with the firewall rules.

Doing a "groupupdate" to "Fedora Workstation" seemed to work better.

Post-upgrade woes:

 - as usual, gnome extensions don't work, since the gnome shell "versioning" is a joke. But at least the Frippery panel favorites updated fine from extensions.gnome.org. And Gnome3 remains quite usable with that extension in place.

 - The "Lock Screen Icon" extension by +Sriram Ramkrishna (highly recommended - yes, I know about cmd-L, but I'm just not a magic keysequence kind of person) apparently isn't up-to-date on gnome.org, but editing the version information by hand to 3.14 makes it work again.

 - the new gnome-terminal seems to default into a new "Emo mode" (aka "Dark Theme"). I don't know who thought it was a good idea to make a terminal application have its own depressed theme different from all other applications, but I'm guessing they spend their days cutting themselves and listening to death metal, and thinking they are "cool". 

But after fixing that, F21 seems to be fine. Knock wood.___

A white puppy may have been a mistake.

Perhaps not by itself, but when combined with "living in Portland" and "teach the dog to walk itself", it turns out that a dog that is more the color of dried mud might have been a better idea.

We got that right pretty much by mistake with our older dog.

So the whole +Subsurface project has grown up, and there's fancy interactive UI stuff etc thanks to all the people involved. And the 4.3 release is imminent, and the project looks good.

But +Dirk Hohndel saw a YouTube video of a Qt project release, and now he wants to take Subsurface to the next level on the release and presentation front too.

Sadly, none of us have any mad skillz when it comes to that kind of thing, so Dirk is reaching out to see if some poor hapless soul wants to wreath him/herself in eternal glory by showing off their presentation skills.

It probably helps if you know what a dive log is, but I think the main skill-set needed here is making a nice presentation video.

I'm looking for someone with a marketing / visual media background (or an inclination for those) who'd be interested in helping us present Subsurface better to its users.
We have a decent user manual, our UI is not terrible, but the way we present ourselves (both on our website and in our announcements) is just lame.
I have neither the talent nor, frankly, the time (I'm busy writing code and fixing bugs and maintaing the project) to do this... but there's so much low hanging fruit and room for improvement.

2,400+ emails of spam in the last six days, and only two of them were real kernel mailing list emails. And even those two were noisy enough that I can kind of see why gmail would have decided they look like spam.

Alan is at it again.

If your hardware isn't quite capable enough for ELKS, maybe you can try Fuzix?

Because who doesn't have an older Z80-based computer or two lying around, looking for a new purpose in life? 

Fed up of SystemD ?
Kdbus the final straw ?
Linux community too large and noisy ?
Yearn for the good old days when you knew every contributor by name and the source code fitted on a single floppy disc ?

I am pleased to announce the initial (very initial) code drop of the Fuzix OS. The goal of Fuzix is to provide a reasonably complete Systen 5 Unix experience without all the bloat. At this point in time the kernel needs about 40K, plus memory for user space.

The Initially supported processor architecture is the Zilog Z80. The code uses no "naughty" instructions so should run correctly on clones and variants, as well as on things like the T80 FPGA core. The core code has been built for 6809 and 6502 as a sanity test but more work would be needed to bring up an actual platform. In theory if it's got 8bits and banked RAM you can probably run Fuzix OS on it.

At this point there is no 8086 port. It's certainly doable for a PC/XT or PC/AT style box but needs a usable open source ANSI C for 8086.. I've done some initial work on pcc (http://pcc.ludd.ltu.se/) but could do with help on bringing that up further as I've not had time to make much progress on it.

So why Fuzix ?

- There are various other "modern" OS for Z80 systems but they are not CPU portable, and except for CP/M mostly non-free or depending upon non-free tools. In time they will become a liability not an aid to playing with old systems

- UZI is neat but constrained by limits in the tools and unbanked memory configuration

- UZI180 is neater but still lacks some basic features

- All the existing UZI variants are forks, and generally incompatible. That's not a long term sustainable way to maintain retro systems.

But in truth the main reason is simpler

- Because it's fun.... and it's halloween which as an ex Red Hatter is kind of the right day for a release

That was not to be.

So 3.17 went through the usual full rc schedule, and it's out today, rather than a week ago. Go get it, and kick the brand new shining tires.

And because I'm now traveling during what would normally be the first week of the merge window, I'm going to delay the merge window instead.  Oh well. 

But hey, if you have your git tree ready for merging, you can always send the pull request early anyway. That will help get your stuff in early once I actually start merging...

And it's definitely not USPS this time. The carrier is supposed to be FedEx, but while they also claimed a yesterday delivery, when 8pm came knocking, that at least changed the estimated delivery to "N/A".

I don't think I can necessarily blame FedEx for it, since Amazon says "in transit to carrier", and FedEx only ever said "initiated". Which makes me suspect it's somewhere in limbo between the two.

Obey!

Hey there - Linux 3.17-rc6 is out, and I'm hoping this is the last rc for this release. 

It would be lovely if people would test it on their hardware (and with their software) to make sure it's all ready. And even if you worry about testing development kernels, by rc6 it really is pretty safe. So go for the cheap karmic brownie points.___Obey!

So three days after I said that all Suunto dive computers are fairly similar, Suunto decides to prove me wrong. Or at least hint that they will prove me wrong. Because this thing sure as hell doesn't look like any of the existing ones.

I've heard rumors, but the only thing Suunto has actually released is the picture on their "News" page:

  http://www.suunto.com/en-US/News/Suuntos-next-generation-dive-computer/

Oh, and +Dirk Hohndel felt that it would be nice to have my dive computer writeup up on the +Subsurface webpage, so while I edited the G+ post a bit, future edits are going to be at

  http://subsurface.hohndel.org/misc/dive-computer-ramblings/linus-dive-computer-ramblings/

because the whole G+ "wall of text" was a bit excessive and the editing of long posts like that is a bit cumbersome.

So hey, I think I've mentioned my scuba diving addiction here before, and even a mention or two of various dive computers I'm using.

I decided I should put together a list of computers I've used, with commentary about them. I'm going to completely ignore the low end that doesn't even allow downloading of dive data, and quite frankly, I personally have used only a few so the list starts out smallish, but maybe there are enough people on G+ that some of you could fill in the gaps.

Non-divers should probably stop here, it's a long wall of text, and not going to be interesting to you anyway.

But if you are a diver, and have relevant information about particular dive computers, add it to the comments. Maybe I'll even edit this post to update it wrt dive computers I'm not personally familiar with if there seems to be sufficient consensus.

  and this post is unlikely to be further updated. Dirk has some commentary about the dive computers he has used too, on his own page. Look under "Misc", it's pretty obvious. ]
 
Suunto

All the Suunto dive computers are fairly similar, although they fall in two classes: the lower-end ones have just three buttons and an old-style LCD display with segments, and the higher end have four buttons and a mostly pixel-based LCD (parts of the LCD is still custom segments, but the bulk of it is pixel-addressable).

The higher end then comes in two different form-factors: the larger "puck" shaped ones (that can be put in a console housing although normally worn on the wrist), and the ones that are more watch-like. But they are generally very similar feature-wise, although you have variations in what capabilities they expose (nitrox vs trimix).

I originally started with a Gekko - the lower-end three-button kind. It's since changed colors and is now called a Zoop, but afaik it's pretty much the same computer with the same features.  The Gekko never officially supported downloading of dive data, but that was just an artificial restriction that was officially lifted in the Zoop - you could actually make even the Gekko do downloads by messing with it sufficiently. 

I currently dive a Vyper Air and a HelO2, both of which are the newer kind with wireless air integration, but still the same puck form factor. I've never used the watch-sized versions myself, but have dove with people who do, and they really are pretty much identical, just with a smaller display and buttons on the side rather than on the front.

One of the primary problems with Suunto dive computers is that it doesn't use the normal Bühlmann decompression model that is pretty much the standard, but Suunto's own "reduced gradient microbubble" model (RGBM). And it is (in)famously conservative, especially for repetitive diving, and particularly if you have short surface intervals.

The "it's very conservative" is sometimes seen and touted as a good thing, and if you're a new diver and likely to be more limited by your air usage than by your nitrogen loading, it's not very noticeable anyway. But if you commonly dive 4+ times a day when you dive, and especially if you do it off small boats where the surface interval is generally less than an hour, it can be quite annoying.

[ Side note: I dive nitrox as much as I can, and that obviously helps with a conservative dive computer. However, nitrox - while very common at the major dive places these days - is not necessarily always available, especially in remote places that can often be interesting dive destinations. ]

On the Vyper Air, you can set your "RGBM factor" to 50%, and that makes the Suunto dive computer act more like most other dive computers, and the HelO2 (as a computer for technical divers) is by default already slightly less conservative (it seems to be quite close to the 50% RGBM mode of the Vyper Air by default). But even with that, the Suunto is still going to be quite conservative, and is still going to be very unhappy with short surface intervals.

The conservatism factor isn't some small detail - I've personally had a dive where I had a 6-minute deco stop kicking against current at 13', while my buddy (+Dirk Hohndel) was still at the bottom with an NDL of 20 minutes. So the "safety" margin can actually result in people just saying "screw it", and then it's not a safety margin any more.

Another issue that is common with Suunto (as in "I've had it multiple times myself, and have talked with others who have seen it") is that the wireless cylinder pressure connection is not very reliable. This is particularly noticeable if you have multiple people using the Suunto wireless transmitters: unlike many other wireless transmission protocols, Suunto doesn't need an explicit pairing code to pair a transmitter and a receiver, but will auto-pair (and has a few different channels so that multiple different transmitters can work).

The auto-pairing can and does result in people getting cross-paired (ie your computer pairs with somebody elses transmitter), and especially on a tight boat where you might be in a hurry to get into your gear and into the water, you may not notice until it's too late.

One good thing about the Suunto transmitter being so promiscuous is that you can have two computers paired to the same transmitter. That's nice if you want the redundancy of actual deco calculations (computers do fail), but obviously isn't any redundancy for any transmitter problems.

I always have either a separate analog SPG as a back-up, or have another wireless transmitter for a third dive computer. I think that's a good idea for any wireless air integration, but it's definitely the case that I've seen more failures with Suunto than with other wireless connections.

I really hope Suunto ends up redesigning their wireless connection. There were apparently a few patents in this area, maybe they are to blame for dive computers sometimes doing silly things.

The third issue I've had with Suunto is that the front-facing buttons can get pressed by mistake, and if you happen to press the right two ones in succession, bad things can happen. I've had my dive computer go into Gauge mode at least twice over the last 300+ dives. Have a backup computer if that happens, because if you started the dive, it won't come out of gauge mode for 24 hours after the last dive. You'll get the raw data and the logging, but no deco calculations.

I've had two other divemasters report the same thing, so it's not just me being a klutz, although it is possible that I'm klutzier than most.  regardless, I really wish gauge mode was in the "settings" menu (which needs a 2-second long-press to get into) than just a simple button-press away from the dive mode.

With all those complaints out of the way, I still have to admit to really liking my Suunto dive computers.  I've been looking around for alternatives, and I've been using others as my backup dive computers, but my Vyper Air tends to still be my main dive computer. But because of the issues I have had with it, I really would not ever dive it as my sole computer.

(Of course, unless you're purely a "vacation diver", I've seen enough problems with just about any dive computer that I would recommend always having a back-up regardless of what dive computer you have. Shit happens).

Small issues: like a lot of other dive computers, Suunto does deco and safety stop countdowns in one-minute increments. Funnily, the deep stops count down in seconds. I'd like to see seconds for all stops. 

Uemis Zurich

Aside from the Suunto's I've been diving, the Uemis Zurich is the dive computer I've used the most, and occasionally as my primary one. It's pretty much a small unknown company with just a single dive computer, but it has one big thing going for it: it has a beautiful OLED screen that is really very readable.

There are a few other OLED screens out there, but until recently, there really wasn't anything that combined the whole package, with a nice wrist-mounted unit that also does air integration. Some of the dive computers in the technical diving area are also OLED, but they tend to eschew air integration.  

And a color OLED screen really is a thing of beauty under water. High contrast makes for a very readable display, and the use of color adds a lot to important warning data, and to make it very clear when you are going into deco etc. You really don't have to worry about seeing the data on the display, even if your mask is fogging up or visibility is really poor (yes, Virginia, sometimes viz is a single foot or so, and you really might have trouble seeing your dive computer display!).

The Uemis also has a nice reliable wireless tank pressure sensor, and the battery in the dive computer (but not pressure sensor) is rechargeable. It also seems to use the standard Bühlmann ZH-L16 decompression model, and in general is just a pretty pleasant computer to use.

It does have a few downsides. The setup can be a bit annoying (editing numerical fields with the three buttons is downright crazy), and the pressure sensor doesn't seem to be coupled to a water sensor, so I've once had it go into dive mode when in an airplane: it clearly thought that I was diving at an altitude of 7500 ft, and when the airplane started descending, the Uemis thought I started my dive. For the rest of that trip, the dive computer was convinced that I was 8' under water, and it didn't clear until the next flight.

That's just stupid, but it seems to be hard to trigger. The problem is that once triggered, you're now screwed for that trip. Even without an actual wet contact sensor, the firmware should realize that if you're charging the dive computer you are really at the surface, and just stop thinking you're 8' under water. But nope. You'd better put the computer in airplane mode before this happens, because after it happens you're done.

The Uemis interface to download the dive data is also particularly odd (yeah, you might even call it crazy), and despite being natively USB, it is incredibly slow and inefficient.  

But when it all works, it's a very nice dive computer. 

Mares Icon HD Net Ready

This one I really really wanted to like. It's a bit big (the Uemis is big, this one feels bigger still), but it has a color display and air integration, and comes from a big company and hopefully without the quirks of the Uemis. Indeed, it downloads dive data quickly over USB, and charges that way too. What's not to like?

Sadly, the screen contrast is not good, to the point that in tropical diving in bright sunlight, it can be actually hard to see the screen in shallow water (particularly at the safety stop at the end of the dive). Which is sad, because the countdown timer is otherwise really nice, and counts minutes and seconds. If you could just see it.

The USB connector is also quite clever at first glance, but while there are ridges to make the connector click in at the right point, they are a great concept that doesn't work well in practice. You end up having to fiddle with it and get it positioned just right.  Again, like the screen, my initial reaction was "Wow, great engineering", but in the end it was just not quite there. 

Atomic Aquatics Cobalt

This one I have only played with above the water surface, but I've talked to several people who dive it, and they pretty much universally love it. The reason it's not on my personal list is that it's a bit too big and bulky for my preferences, and while air-integrated, it's hose-based rather than with a wireless transmitter.

But it has a beautiful big bright color OLED screen, and the easiest user interface I've ever seen on a dive computer. Yeah, yeah, they had a recall where the high-pressure connector would fail and the screen would blow up in your face, but boy was the shrapnel beautiful while it did so. And they did fix it. 

I'd really recommend the Cobalt as a beginner dive computer, just because it's so readable and easy to use. The only downside is that if you're a beginner diver, you might be scared away by the price. It's just not priced for a novice diver. Not that anything else Atomic Aquatics does is either, so what else is new? 

There's a "rev 2" of the Cobalt that I haven't seen, but it seems like the main difference is improved performance of the internal CPU.

Also, is is worth noting that since I haven't used it for diving personally, maybe I've missed some practical downsides.

OSTC 3

This is a really lovely formfactor dive computer with a great color LCD screen, made by Heinrichs Weikamp. And unlike the Icon HD, the LCD screen seems to be quite readable. Possibly it's an IPS vs TN issue, or just the protective glass/plastic. Or even just color scheme. Regardless, it's a good LCD screen.

There's a recreational version of it ("OSTC Sport") that does just Nitrox, and adds bluetooth communication for downloads. I've not seen that one in person yet. Even for the OSTC 3, I've seen and used just the pre-production versions of the OSTC3, and they had some annoying issues with the buttons and a bad pressure sensor, but that should all be fixed in the production versions.

And it really is a very nice and compact dive computer, with a beautiful screen and reasonably easy to use. If it had air integration, I'd be in hog heaven. But it doesn't. The technical diver version (so not the "sport") has an optical connection for rebreather sensors, but there's nothing for us open-circuit people. Oh, well. So close.

Aeris A300CS

I don't have this one yet, but it's on order. On paper, it does everything right - OLED screen, wireless air integration, and bluetooth downloading of dive data to your phone and desktop/laptop computer. Let's hope it lives up to the promise. I'll update this when I have more experience with it.

[ Editing a bit based on comments. So it's even longer. I warned you guys ]

Shearwater Petrel

This one got mentioned by several comments, and I agree: it looks like a great dive computer. It's most comparable in features to the OSTC3, sadly sharing the same lack of air integration, but with a great screen and a company with a long history of technical dive computers behind it.

I haven't used it myself, so I can't really comment more on it, but I also haven't heard anything bad about it. It seems to be much more common in the tech diving community than the recreational divers.



[Explanation of personal preferences]

So just as more background about why I care about dive computers in the first place, and some specific features of them, I'll just run through why I happen to have the preferences I do. They may not match yours, but hopefully they explain why I care about things that some people say "Why?" about.

The first issue is "why a dive computer". I realize you can dive without one, especially as a vacation diver just following the dive master. But the dive computer was the first piece of actual dive equipment I ever bought, because you need to have something down there even if it's just a timer, and you might as well have the right thing. And dive computers do a better job than tables.

Sure, there are other things that are even more important from a dive safety standpoint than having a computer be happy (be well hydrated,  don't ever do fast ascents, do your safety stop even if you don't have to, etc), so the dive computer isn't primary to your safety, but it's just a good tool. If you dive more than once or twice a year, just get one. 

Why air integration?

A lot of divers scoff at air integration. Particularly technical ones. They are wrong.

It's not that air integration is all that important under water: you don't run out of air suddenly and unexpectedly, and having a separate SPG for cylinder pressure isn't that much of an extra burden. And at the same time, it's very true that reliability is absolutely critical when it comes to air, and if your wireless link fails (or computer fails entirely), and you don't have any backup SPG's, air integration means that you'd have to abort your dive.

So technical divers in particular just see it as an extra failure point. 

But they miss the big point. Sure, you want backups (and technical divers know that), but the really big advantage of air integration in your dive computer is logging. During the dive, you can glance at your air a couple to times to know everything is ok. But after the dive, air integration in the dive computer means that you can see just how much air you used, and often also at which point in the dive. That is very useful. You can see "Oh, I swam hard after the octopus that got away, and I can see how my air consumption went up for five minutes afterwards".

Air integration also allows the dive computer to show an estimated "air time remaining" field, which is just really convenient. It's not a big deal, but it's why I tend to use my Vyper Air as my primary (it shows airtime), and the HelO2 as just a backup (it, being sold to tech divers, hides the fact that I'm sure it actually has the exact same calculations). It's just a nice useful thing.

"Why do you care about fancy screens? I can see everything important on my old monochrome LCD with seven-segment numbers".

Yes, you can see the numbers. Except when you can't. On night-dives, or in bad visibility, or when your mask fogs up, or when you're at 150' (40m) and narced out of your mind, you want more than "can see the numbers": you want to be able to still glance at your dive computer and see them without even having to think about it. 

Having to press a button to get a backlight in order to see your dive status is easy, yes. But there might be equipment (cameras, flashlighs, whatever) you're holding, and even if there isn't, it turns the "check your dive computer" from a quick glance to something you have to actively do.  Having the display just always be readable is just a good thing.

And color - and high resolution - adds a lot to the "it's readable" equation. If you have a fixed layout with segmented numbers, you by definition cannot change the layout to accomodate different situations, and you'll always have to basically just have these cryptic special markers to show different events. But if you have a high-res color screen, you can show good things in green, warnings in orange, and bad things in red. And you can make supplementary information in a small font in a different color etc. ___

So it could have been a complete non-event. Big deal. But why did I end up being really really annoyed about it?

Because yeah, I'm annoyed about it, not because my package didn't arrive, but because the whole tracking page says that delivery was attempted, but the "Business was closed".

Yeah, there's been at least two people home the whole day, there was no delivery paper slip at the door or at the mailbox, and pretty clearly nobody actually tried to deliver anything at all.  Or if they did try to, they had a very "Ninja" approach to delivery.

The only business that was closed was clearly the USPS, and the previous entry about the package being "out for delivery" was just entirely made up. Or maybe it was out for delivery, but somebody realized that it's sunny and 85°F outside, and there are better things to do than lug around mail on a Sunday. Fair enough.

But guys, if for some reason you can't deliver stuff, please don't lie about it, ok? If the tracking entry and email had said "Delivery delayed until Monday, today is just too nice a day to bother", everything would have been fine. 

I love both my regular USPS delivery guy ("Raining and 50°F in January? That's shorts weather!") and Amazon ("Whee, now I have no reason to ever exit the house at all!"), and a delivery snafu wouldn't bother me at all..

But lying about it? That's just low.

USPS, Just add a "sorry, too busy, be back tomorrow" entry, if the problem is that nobody actually got around to it. Trust me, honesty is the best approach wrt things like this. Just own your failure, don't try to blame the victim.___

Heh. I have a Finland section for google news, and today it talks about the heat warning in force for most of Finland.

Yeah, that's three days of over 30°C. That's 86° in Freedom units, for those that can't math.

The record this summer so far has apparently been 31.8°C, which is not quite enough to break 90F.
