KSP computer overheated

2009-07-14T12:52:00.003+03:00

Once, lot's of shots of rum ago, when rockeiter did not know that all it's emploees will have a laptops , our CEO bougt two PCs from a local computer store (KSP). The thing is with those KSP guys is , that mine probability for getting a good computer from them equals to the probability of meeting a dinosaur on the street (it's 50 \50 either do , or not ).

Nowdays , when one of the computers runs 3 databases servers the heat control is dead we came up with an alterative cooling device.

The comp lays on an air conditioner and acually is very cool :)

don't buy at KSP

Official TowelDay site

To quote from The Hitchhiker's Guide to the Galaxy.

A towel, it says, is about the most massively useful thing an interstellar hitch hiker can have. Partly it has great practical
value - you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you - daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.

More importantly, a towel has immense psychological value. For some reason, if a strag (strag: non-hitch hiker) discovers that a hitch hiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, face flannel, soap, tin of biscuits, flask, compass, map, ball of string, gnat spray, wet weather gear, space suit etc., etc. Furthermore, the strag will then happily lend the hitch hiker any of these or a dozen other items that the hitch hiker might accidentally have "lost". What the strag will think is that any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is is clearly a man to be reckoned with.

Window size

2009-01-15T18:46:00.000+02:00

have you ever been arguing with your collegues about opening the window or closing one ? well in out opinion the problem is the work itself, we just don't like getting up from the chair and openning or closing the window..

Our High Preformance Development Team has developed a very usefull and handy API for a window size controlling .

You can use it whidely and proudly and shock your bosses and colugues (our boss smiled) by this..

The API is avalible under the Open_source_license.
If there are problems, we will find someone to accuse :)

RomDiff

2008-12-30T19:23:00.002+02:00

Hi
that's me again .. busy day today , huh ?

Anyway, while I was thinking of something, Romi, my colleague fond out that a file a his won't compile. He decided to check the differences of the files.

that is why we invented the RomDiff

Windows Pay - Per Use ? maybe soon

2008-12-30T18:27:00.003+02:00

Microsoft has applied a patent of renting an operation system and probably hardware .
Imagine that you have a small cheap computer and suddenly you have an urge to kill, you know ... you just need to kick ass .. what shall you do ?

What I do is - take my Lenovo T61P Super Mega Laptop, run a battlefield and then have a nice time while shooting bad guys , flying helicopters and wasting time, however as I told you have a cheap computer . A problem ? Not anymore!

You can rent an nVidia Video card and a good sound adapter for a hour of two , pay some bucks (two three .. whatever) and when you done using them you just stop paying. Now of course you will not see a Microsoft delivery guy bringing you the hardware, it will be installed in your computer, but deactivated.

Moreover, all the XboxLinux project and the others taught Microsoft a lesson about obfuscating options of the computer hardware, therefore, we shall see more Hackers and security professionals hacking the security infrastructure of this "Device".

Here is a quote from Microsoft's patent application form

A different business model may allow a more granular approach to hardware and software sales. A computer may have individually metered hardware and software components that a user can select and activate based on current need. Beyond simple activation, the user may be able to select a level of performance related to processor, memory, graphics power, etc. that is driven not by a lifetime maximum requirement, but rather by the need of the moment. When the need is browsing, a low level of performance may be used and when network-based interactive gaming is the need of the moment, the highest available performance may be made available to the user.

let the fun begin !

Firefox vs Internet Explorer

2008-12-04T10:54:00.006+02:00

Another frustrating difference between the Firefox and Internet Explorer. A simple script in one of my pages selects all of the checkboxes in the page

function ChangeCheckBoxState(id, checkState)
{
var cb = document.getElementById(id);
if (cb != null)
cb.checked = checkState;
}

function ChangeAllCheckBoxStates(sender)
{
var checkState = sender.checked;
// Toggles through all of the checkboxes defined in the CheckBoxIDs array
// and updates their value to the checkState input parameter

alert('1');
if (cbCheckBoxList != null)
{
for (var i = 0; i < cbCheckBoxList.length; i++)
ChangeCheckBoxState(cbCheckBoxList[i], checkState);
}
}

here is a trigger

&lt input type="checkbox" id="cbSelectAll" onchange="ChangeAllCheckBoxStates(this)" &gt

So, here is the issue: while Firefox handles everything well , Internet Explorer needs me to check or uncheck the box and then to click on some other area on the scree

I Hate that , why ? isn't is the meaning of ONCHAGE event ??!@ huh ?

Hightech is in shit

2008-12-03T14:27:00.003+02:00

I have been programming for the whole morning .. well not for the whole morning , because I could not stand on my feet in the morning .. We were presenting ourselves at the IGT2008 - The World Summit of Cloud Computing, and my feet were ruined. I will write a post about it as soon as i get the pictures.

Anyway when I went to find myself a sandwich , I was surrounded with sewerage. It looked like a huge buffer overflow with no debugger available and the smell was the same the buffer overflow should have .

They are right, Israeli Hi Tech is in deep shit .

VoTP

2008-11-30T20:59:00.002+02:00

Voice over Though Protocol (VoTP) is a general name for a set of telepathy communications.

VoTP is usually observed in human beings, and is thought to exist in other mammals as well.

VoTP can deliver a short message or initiate a conversation, but only with the rise of telephony systems, have these become into popular use.

It can be used as a toll-free initiation method for a call.

When you call someone, thinking you just wanted to talk to them, and they reply "thanks for calling, I was just thinking of you and wanted to talk to you", they've used it!

Buisness card

2008-11-27T19:01:00.006+02:00

A good friend of mine, the one who sent me to make her a coffee five minutes after I first met her, told me that a business cards of the company we worked in (Comsec consulting) are very good for making a shopping list, since they are made of a good paper and the back side of them is free of text. It was nice and handy. Now working in Rocketier, we have a problem with that since the back side of the card has some text saying
Startup your engines

Detect
Rate
Immediate Effective Relief
Roadmap Planning
Scale up & Scale out

After talking about the card with the colleagues of mine and telling them that I will probably have to buy a notepad (a paper one) or write some program to the PDA , I noticed that the card, actually, fits me perfectly, becaue it describes the beer drinking process. Next time I drink beer (tonnight ?!) - I will be prepared.

High Performance CEO Blog

2008-11-27T18:17:00.002+02:00

This blog started as a means to conserve internal jokes, persist them from the erasable board, and bring the R&D team closer.

Management wondered where did the jokes disappear from the whiteboard, and made room for some agile management tasks list.

And then... the Cloud Computing, Software and System Performance blog came online!

Now you can finally catch up on what we are WORKING on, when we are not writing in this blog.

Find us at IGT2008 - The World Summit of Cloud Computing, next to Google, Sun and Amazon.

Thermodynamics

2008-09-15T16:00:00.004+03:00

When I was studying chemistry in the high school, I remember that the beloved Dr. Nana (for real) was talking about all worlds connection, and that it is not only connected by the physicals and chemical reactions , but there are psycological and political applications to the approach discussed

Today's , picking to a facebook for a second before food, made me remember the first law of the thermodynamics, about the conservation of the energy..

....'' The change in the internal energy is equal to the amount added by heating minus the amount lost by doing work on the environment ''...

Google Chrome Language

2008-09-02T22:26:00.002+03:00

After installing Google's Chrome to the system I was disappointed by the language of the interface

it was hebrew, either because I'm located in Israel , or because this is my default system encodig.

Here is how you make Chrome to "talk" English , on in any other language you prefer:

Locate the key pictogram, it is in the end of the adress bar
Click on it :-)
Select the "Options ", it is the fourth (4) line from the end or sixst (6) from the top
Select the middle tab (minor tweaks)
In the lowest section of the tab (fonts and languages) click the long button : "change font and language settings ".
Go to the another tab , not the selected one (Languages)
In the combo boxes select the wanted language (ENGLISH MO#$$FU#$@ DO YOU SPEAK IT ?!)

Debugging

2008-08-19T23:38:00.002+03:00

If you have software problems, use Visual Studio's debugger.

But for the real bugs, use Sano's K300.
