Wow, optimized a #query which was slow only the first time! (in MS SQL Server 2008+)
After lots of searching I found at least a query to find #slow #compile queries
(with high cpu and memory usage):
http://www.sqlskills.com/blogs/jonathan/identifying-high-compile-time-statements-from-the-plan-cache/

Together with a "clear all cache" sql I could reproduce and optimize the slow query:
DBCC FREEPROCCACHE; DBCC DROPCLEANBUFFERS; DBCC FREESESSIONCACHE; DBCC FREESYSTEMCACHE ('ALL');

It turns out that you should not use (many) "view in view in view in view" :)
After combining all views into one big sql (with sub select in sub select in sub join etc) I got from "10s + 81Mb" to "1.2s + 17Mb" compile time and memory usage! 
Wow, is Sql Server so in-efficient in compiling subsubsubsub views?

Been at the Microsoft TechDays 2013 today in The Netherlands... It was disappointing, most stuff could have been told in a simple blog post, not in a 1 hour and 15 minutes long "presentation"! (I was watching the clock often to see it moving slooowly...). Even the "highest" level 400 session about HTML5 was about basic html5 stuff (canvas, geolocation, etc).
All right, yesterday appeared to be a better day but I had a funeral then, so I "had" to go (by my boss) today.
Also much less attendants than previous year (heard from my boss) and MS is spending much less money on conferences. Makes you thinking...

Opera to use WebKit

Opera has made a very interesting announcement: "for all new products Opera will use WebKit as its rendering engine and V8 as its JavaScript engine."

What's your take on this as a developer? Is this a good move on Opera's part? What will distinguish it from Chrome?

Strange, I did some hacking and profiling to see how fast I could get Datasnap, and I see that also my "Plain Indy" is much slower in XE3 than D2010! In D2010 is get about 11.500 request per second, the same in XE3 only 7.700...
After some hacking (mainly disabling the sessions) I got 4700 req/s (was 3200reg/s) and also stable performance (no steep decline). I could not get more without much rework...

When looking at the DS source code my conclusion is: it is not optimized for "high performance" (stupid advertisement of EMBT!). I mean: all kinds of helper objects are created and destroyed on the fly, many UTF8 decoding conversions (implicit due to rtti?), RTTI context is not cached, no connection pool (new connections are created and closed for each request), etc. 

Anyway: does anyone know why Indy in XE3 is slower?

HTML5 browser for WinCE/Win Mobile:
http://www.zetakey.com/product.php

Maybe you're thinking: why would one need it?
But for my current customer it can be indeed important because almost all
rugged barcode scanners have WinCE with ancient IE4 or something like that :(
But now we can use normal html in WinCE (don't expect high speed animations of course on this old hardware :) )

You can also build it on your own from the webkit sources:

.Net: it is (too) easy to be inefficient? 
http://www.bluebytesoftware.com/blog/2012/10/31/BewareTheString.aspx

But you should be aware of (too much) allocations in Delphi too!

And don't start with "micro optimalisations are evil", because you just should be aware of what you are programming: if you are programming a function that is used many times (or should be fast), then really think about speed and optimal code in mind and not about "easy code", less lines of code, etc. So KNOW into how much cpu instructions a single statement will be generated.
This is easier in Delphi than in .Net, .Net is too much abstracted for developers

Wow:

"I want to make one return to the beginning. Remember his first 5 months? Elop actually inherited a company with strong handset sales - the unit sales grew both at the smartphone unit and the featurephones unit. The revenues grew at both units. Both units were very healthy and profitable, the smartphone unit has a huge jump in its profits and profitability towads the end of the year 2010. Lets bring this reality back to the picture. So I am taking the above, and adding now the previous 12 months to the picture. I also make a few other observations in the diagram. This is the true story of the Three Pillars of Stephen Elop's New Nokia Strategy as of June 30, 2012. He has wiped out 21 Billion Euros (27 Billion US dollars) of Nokia handset revenues in the past 20 months (and turned growing profits into growing losses). This is what misery looks like:" more »

Did a small test to create a lot of small objects (10.000.000)
- normal create in a for loop and TTestObject.Create
- alloc 1 big mem block, copy hidden classtype etc and call create function.

Result (release mode, D2010)
- normal = 339ms, 270Mb memory
- hacked = 148ms with .Create, 65ms without .Create, 194Mb

Especially without calling the .Create function (acts as function on an object, normally is acts as a constructor!) it is a lot faster. And because it has not an extra memory header overhead per object, it consumes less memory (also less fragmentation).

Note: It is only useful when you have a special high speed batch function, with limited scope and lifetime (do not mix normal creates and hacked creates!).

Note2: in a real application the speed difference will be a lot bigger, in the above PoC we have a tight loop so all stuff of the... more »

Did a small test with #ADO  and MARS ( #sqlserver ): it seems you can execute multiple update/insert/select statements in different(!)  #threads using 1 connection and within 1 #transaction ! So a rollback of the transaction undoes everything done in all the other threads!

Has anyone experience with this? Because I would like to use it in our software to paralelize a big function (consists of different updates/inserts in different DB tables, but everything must be execute within 1 transaction). Is it really #threadsafe  to do? In a small stress test it performs like expected...

Interesting: using a #NoSQL  database (like MongoDB) for superfast logging (also with rotating capabilities!):
http://blog.mongodb.org/post/172254834/mongodb-is-fantastic-for-logging

Nice to know is that is uses #javascript  in the shell and for MapReduce (to reduce data by calculating average per 15min, per day, etc) scripts:
http://www.mongodb.org/display/DOCS/Scripting+the+shell

By the way: you cannot use SQL for quering but a JSON like "find":

Did a small test in #Delphi  with TMongoWire and it looks very promising to log in a "variable structure" database!

A picture began circulating in November. It should be "The Picture of the Year," or perhaps, "Picture of the Decade." It won't be. In fact, unless you obtained a copy of the U.S. paper which published it, you probably would never have seen it.

The picture is that of a 21-week-old unborn baby named Samuel Alexander Armas, who is being operated on by surgeon named Joseph Bruner. The baby was diagnosed with spina bifida and would not survive if removed from his mother's womb. Little Samuel's mother, Julie Armas, is an obstetrics nurse in Atlanta. She knew of Dr. Bruner's remarkable surgical procedure. Practicing at Vanderbilt University Medical Center in Nashville, he performs these special operations while the baby is still in the womb.

During the procedure, the doctor removes the uterus via C-section and makes a small incision to operate on the baby.... more »

Just want to make people aware that the latest hotfix contains some "unseen" goodies. First of all we have updated the internal browser to the latest version of chromium, so the c++ engine is up to date with the latest advances. The compiler have also seen a fair bit of work, including support for "class external" which allows you to map directly to javascript objects (see Remobjects SDK generated files, it's fairly straight forward). Oh and did you notice the webGL wrappers in the RTL?

And we finally have user-editable layout sizes. So now you can edit and add whatever target sizes you want. And the browser doesn't forget your last preferred settings.

Also, we managed to get CTRL + Click added (although some combo behavior is still missing, like toggle between implementation and interface) and mouse-over hints. Since there are quite a number of symbols (the... more »
