FIX: A disk read error occurred. Press Ctrl+Alt+Del to restart
Recently I suffered from a total system breakdown. Windows suddenly decided to stop booting, I didn't believe the cause of the error was bad hardware (faulty HDD) - the laptop is new.
I struggeled to find a solution, tried many things with the Windows installation disks. None of the automatic repair tools helped (system restore, automatic startup repair, boot-repair-disk).
It seemed the cause of the error was a broken MBR, caused by a process with access to system files, but boot-repair-disk didn't fix it.
After some more googling I found out that the Windows installation disk has another MBR fix tool, accessable from the command prompt.
Boot the system from the Windows installation DVD, then open up command prompt either with Shift+10 or by choosing it from the menu.
Then type:
bootsect.exe /nt60 C:

Windows 7 SSD Tips
The list may be updated.
- You probably already know this:
Install large programs on the HDD instead of the SSD drive. - Disabling hibernation saves you X GBs on the SSD drive, where X is the size of your RAM.
Run cmd as administrator.
Type in: powercfg -h off - Move Documents, Movies, Pictures, Music folder on the HDD drive.
Moving these directories is easy. Just right-click on them, click Properties, click Location and click Move. - Move AppData folder - this is the folder where your installed programs store temporary and/or your local data which is used by those programs. It can grow really large in size.
There is no simple procedure to do this, so this option is not really preferred. - Move the whole Users folder.
LifeHacker has an article about it. Again, not a really simple solution.

Windows 7 File permission problem after reinstallation
Run command line as administrator
For Folders or Directories (will perform action recursively):
takeown /f directory_name /r /d y
icacls directory_name /grant administrators:F /t
Replace file_name or directory_name with actual file name or folder name, with path when applicable. The first command will take ownership of the file or folder specified, and the second command will grant full control permissions to administrators user group. Note that when using command for folders, to command will run recursively. To prevent the task been perform recursively, remove the “/r” and “/t” switch.

SiOL TV, dve mrežni kartici, VLC player, Windows 7 x64-bit
V primeru da vam IPTv ne deluje, če imate dve mrežni kartici (eno za internet in drugo za TV), poskusite pri mrežnem adapterju za TV nastaviti metriko na 2.
Ne pozabite na ostale nastavitve za vzpostavitev TV na VLC playerju:
-odprite VLC in pritisnite CTRL+P (Preferences)
-spodaj levo obkljukate Show settings "All"-s tem se omogočijo napredne nastavitve
-v meniju gremo na Input/Codecs - na desni pri UDP portu vnesemo pravi port, ki je za t2 "5000", pri MTU pa imam "1492", potem pa še obkljukamo "Force IPv4"
-gremo v meni "Video" in nato kliknemo "output modules" - pri "Video output modules" izberemo možnost iz seznama "OpenGL video output"
-nato v levem meniju izberemo meni "Stream output" in nato "Access output"
-V Access output sem v okence kjer piše "Multicast output interface" vpisal IP mrežne kartice, ki jo uporabljam za internet, v okence "IPv4 multicast output interface adress" pa sem vpisal IP mrežne kartice, ki jo uporabljam zgolj za IPTV
-zadevo shranite in ponovno zaženite program.

Custom page numbering in MS Word
I'm sure most of you came across this problem before - how to add custom page numbering.
I don't really like making seperate documents for the pages I don't want numbered and options in MS Word are preety limited. You can set up the numbering to start with a different number. You can't, however, set it up to start with a negative number.
Example: You have the first three pages you don't want numbered (front page, page index, thanks). Everything after those pages is numbered and starts with 1.
- Go to the header/footer - wherever you want to set up page numbering.
- Add page numbering, set it up to start with zero and check the option to have a different header/footer on the first page. This way the front page will have the page number zero, but you can delete numbering for that page.
- Now you need to "extend" the first page, so that the second (or third) page will also be unnumbered. You can do this with page breaks, go to Insert -> page break. There are a couple of different page breaks, choose the one that fits your needs.
There's an other way to do a completely custom page numbering, but it involves a tiny amount of "programming" and it won't work the same if you add page index, but here goes:
- Go to the header/footer
- Retype this code for the example above:
The important thing here is that you need to press CTRL+F9 to get the curly braces. If you retype them, it won't work.
- After you've written the conditions for page numbering, right-click on it and choose "Update field".
Here are some other examples:

- After you've written the conditions for page numbering, right-click on it and choose "Update field".
{ IF { PAGE } < 4 "" "{ = { PAGE } - 3 }" }
This is a simple conditional statement, if the current page number is less than four, the first argument (The empty "" string) will be used, otherwise it will calculate the current page number minus three.
Here are some other examples:
{ IF { PAGE } < 3 "" "{ = { PAGE } - 2 }" }
Skip the first two pages
{ IF { PAGE } < 3 "{ PAGE }" "{ = { PAGE } + 5 }" }
Number the first two pages normally, then add 5 to the current page number.
{ IF { PAGE } < 3 "{ PAGE }" "" }
Add a page number only to the first two pages.

Windows 7/Vista & ArcGIS & ESRI License Manager
It seems that ESRI License Manager has difficulties running in Windows 7 or Vista – the License server fails to start at boot or on demand in License Manager Tools.
Consequently, ArcGIS didn’t start because there was no license server running. Obviously this problem doesn’t occur if the license server is running on another machine in the network.
At first I tried the quick and dirty solution – to manually start the server daemon and see where it fails.
I ran Command Prompt as an administrator:
Now, the server is called lmgrd.exe, so if you navigate to C:\Program Files\ESRI\License\arcgis9x and start lmgrd, it says that there is no license specified.
So I typed the location of the license (it was in the same folder), ran the program in the foreground:
lmgrd –c license.lic -z
I kept the command prompt open, and ArcGIS started succesfully.
But this isn’t really a long term solution, since this method would require manual server start in the command prompt everytime I would want to start ArcGIS.
So I thought, maybe the problem is that the server can’t find the license file. After some googling, I found out that the environment variable LM_LICENSE_FILE wasn’t set. It says on the support page that you’d need to enter port@machine-name for the variable value, but since we’re running the server on the local machine, you just need to enter your C:\Path\to\your\license.lic.
When all goes well with License Manager Tools, you might still need to enter "localhost" in the ArcGIS desktop manager in the license server.
If anyone has a better solution or information, please post in the comments.
UPDATE:
After further experimentation I found out that you also need the Sentinel driver to successfuly run License Manager on Windows 7. Don't know why, but it works. You should install Sentinel driver first, then the license manager, so that everything for the license works before you install ArcGIS. That way you won't have to manually configure ArcGIS for license after it has been installed. You have less work that way.

Windows Tips: How Be Safe From Viruses / Kako ostati varen pred virusi
English version | Slovene version
Here's a non-developing blog entry... So, how to be safe from viruses?
I get asked this question a lot lately (wish I knew why, is there a new dark age coming or something?), especially which Anti-Virus software should one use, to be 100% safe from viruses.
Well, I'm not a big fan of Anti-Virus programs (I do use one, for "just in case"), nor do I want to advertise such software and above all, I don't think that any program can ensure full security.
Here's why (sorry for the lecture):
Viruses exist for any Operating System (Windows, Linux, ...). They're not called the same on different operating systems, but they act the same. They have simmilar methods of reproduction, and so on. Making a virus is very easy, even if you are a beginner at programming, making a good virus is a bit harder, but not much. A virus is a program, like any other, but it does stuff it's not supposed to, and that's why it's flagged as being a virus (malicious). And because it's a program, detecting it may be difficult sometimes, because it's functions don't look as fishy as they actually are - the program does things any normal program would do, let's say connects to a server and communicates with it. A lot of programs do that. Your browser does that. Your browser could be a "virus" if it would let someone else have access to things they're not supposed to.
Okay, enough of that, let's get to the good part.
Here's a short list of 4 simple tips you should follow, and if you'll follow all of them, you'll quickly find out that you don't have any use of your Anti-Virus program anymore.
They mostly apply on Windows Operating systems, but the idea is general.
Well that's all folks, I hope this article widens your horizon on computer security. Because I'm in an extra helping mood today, I'll translate the article for all of my Slovene friends.

Zdaj pa en ne-programerski članek. Kako ostati varen pred virusi?
Zadnje čase dobivam to vprašanje zelo pogosto (ko bi le vedel zakaj, prihaja kakšna temna doba ali kaj podobnega?), še posebej: kateri Anti-Virus program naj bi uporabili, da bi bili 100% varni pred virusi.
Nisem ravno navdušen nad AntiVirus programi (sicer uporabljam enega "za vsak primer"), nimam niti želje oglaševati teh programov in povrh vsega, ne verjamem, da lahko program zagotovi popolno varnost.
Še razlog zakaj (oprostite za pridigo):
Virusi obstajajo za vsak Operacijski Sistem (Windows, Linux, ...). Ne kličejo se povsod enako, vendar obnašajo se isto. Imajo podobne načine razmnoževajna in tako naprej. Narediti virus je zelo lahko, tudi za začetnika programiranja. Narediti dober virus je malo težje, vendar ne veliko.
Virus je program, kot vsak drugi, le da počne stvari, ki jih nebi smel in zato je označen kot "virus". In ker je program kot vsak program je včasih zelo težko ga odkriti. Včasih so funkcije virusa zelo podobne običajnim programom, recimo, program se poveže na strežnik in z njim komunicira. Veliko programov to počne. Vaš brskalnik to počne. Vaš brskalnik bi lahko bil virus, če bi dovolil nekomu dostop do reči, do katerih nebi smel.
No, dovolj tega, preidimo do bistva.
Tukaj je kratek seznam štirih preprostih namigov, katerim lahko sledite, če pa upoštevate vse, lahko hitro ugotovite, da nimate več potrebe po uporabi antivirusnega programa.
Namigi so večinoma za Windows operacijske sisteme, vendar velja za vse.

They mostly apply on Windows Operating systems, but the idea is general.
- Disable Auto-Run
Disable it. Disable it for everything. For CDs, USB keys, everything. It's useless and it's a major security problem. It's also a VERY popular way of virus reproduction.
If you don't know what Auto-Run is, read about it on the wiki, but in a nutshell, AutoRun is a Windows service that enables a computer to run a program automatically when you plug in your USB key or a CD/DVD. Running a program whitout knowing what it is is like jumping from a bridge. It's dangerous and it's very likely that you'll get hurt.
I'll be short on How-Tos, but here are some links:
- http://www.howtogeek.com/howto/windows/disable-autoplay-of-audio-cds-and-usb-drives/
- http://antivirus.about.com/od/securitytips/ht/autorun.htm
- http://features.engadget.com/2004/06/29/how-to-tuesday-disable-autorun-on-windows/
Also, if you don't know how to disable AutoRun, there is an alternative:
If you hold the Shift key when you plug in a USB key/CD, you temporarily disable AutoRun.
- Use a firewall
Firewalls come in many forms - there are physical firewalls, such as routers (but firewalling is not the router's primary function), and there are software firewalls.
Firewalls block certain types of internet communication. They filter open ports which is also a very common way for virus reproduction:
An infected machine connects through the internet to another vulnerable machine which has a vulnerable service running. But note that:
- A computer is only vulnerable if it has a vulnerable service running
- If the computer has no open ports (no services running) it cannot be infected/hacked via the internet.
- Updates!
A lot of people disable automatic updating (Control panel\System Properties\Automatic updates), because either they're afraid they might get that annoying little Windows Genuine Advantage tool or that they'll get viruses from it. Viruses from Microsoft updates?!?! Come on...
Updates are in most cases a very good thing to do - if you don't care about security, you should at least care about the cool new features you get with the new version of any program. Programmers don't always get it right in the first try, that's why updates come in handy.
- Use your brain
You heard me. Don't be stupid. Don't click on everything shiny, don't click on anything before reading what it is and understanding what it does. Don't open every email attachment. When you're browsing on the web, don't click on every link. Look at where it's pointing (in the status bar). If it's an .EXE file (a program) be extra careful, don't run it if you don't know what it is. KeyGens are NEVER what they say they are on the internet. Don't click on every "OK" or "I Agree" button. Some people think that when they suddenly have an unknown toolbar in their favourite browser, they have a virus. That's not true. They got that toolbar when they clicked on "I Agree" sometime in the near past without reading what it does.
Well that's all folks, I hope this article widens your horizon on computer security. Because I'm in an extra helping mood today, I'll translate the article for all of my Slovene friends.

Tukaj je kratek seznam štirih preprostih namigov, katerim lahko sledite, če pa upoštevate vse, lahko hitro ugotovite, da nimate več potrebe po uporabi antivirusnega programa.
Namigi so večinoma za Windows operacijske sisteme, vendar velja za vse.
- Izklopite Auto-Run
Izklopite ga. Izklopite ga za vse. Za CD-je, USB ključke, vse. Neuporaben je in jezelo velik problem kar se tiče varnosti. Poleg tega je to zelo popularen način za samodejno razmnoževanje virusov.
Če ne veste kaj je AutoRun, preberite o tem na Wikiju, v bistvu je pa to orodje operacijskega sistema Windows, ki omogoča samodejno zaganjanje programov, ko priklopite USB ključ ali CD/DVD v računalnik. Zaganjanje programov, brez vedeti kaj počno je kot skakanje čez most. Je nevarno in zelo verjetno je, da se boste poškodovali.
Bom kratek pri navodilih kako to izklopiti, tukaj je pa nekaj povezav o tem:- http://www.howtogeek.com/howto/windows/disable-autoplay-of-audio-cds-and-usb-drives/
- http://antivirus.about.com/od/securitytips/ht/autorun.htm
- http://features.engadget.com/2004/06/29/how-to-tuesday-disable-autorun-on-windows/
Če ne znate izklopiti AutoRun, obstaja alternativa:
Če držite tipko Shift, ko priklopite USB ključ ali CD s tem začasno izklopite AutoRun.
- Uporabljajte požarni zid
Požarni zidovi obstajajo v različnih oblikah - obstajajo fizični požarni zidovi kot so usmerjevalniki (vendar požarni zid ni glavna funkcija usmerjevalnika), obstajajo pa tudi programski požarni zidovi. Požarni zid blokira določene vrste komunikacije prek iterneta. Filtrirajo odprta vrata kar je tudi zelo razširjen način razmnoževanja virusov:
Okužen računalnik se poveže na ranljivega prek interneta, na katerem teče ranljiv program. Vendar pomnite:
- Računalnik je ranljiv samo, če na njim teče ranljiv program
- Če na računalniku ni odprtih vrat, potem ta računalnik ne more biti okužen preko interneta / vanj se ne da vdreti preko interneta.
- Posodabljanje!
Veliko ljudi izklopi avtomatično posodabljanje (Nadzorna plošča\Sistem\Avtomatične posodobitve). Ali se bojijo, da bodo s tem dobili tisto nadležno Windows Genuine Advantage orodje, ali pa da bodo s tem dobili viruse. Virusi pri posodabljanju Microsoft?!?! Dajte no...
Posodabljanje je v zelo veliki večini primerov zelo dobra stvar - če vas ne zanima varnost na računalniku, vas bi lahko vsaj zanimale vse nove in kul funkcije, ki jih dobite z novo verzijo programa. Programerji ne zadenejo vse v prvo, zato pridejo posodobitve zelo prav.
- Uporabljajte možgane
Prav ste me slišali. Ne bodite neumni. Ne klikajte na vse kar se sveti, ne klikajte na karkoli, predno preberete kaj piše in razumete kaj bo stvar storila. Ne odpirajte vsake priponke v spletni pošti. Če brskate po spletu, ne klikajte na vsako povezavo, poglejte kam kaže (na dnu programa piše). Če je povezava .EXE datoteka (program) bodite še posebej previdni, ne zaganjajte ga, če ne veste kaj bo storil. KeyGeni niso NIKOLI kar pravijo da so na internetu. Ne klikajte na vsak "V redu" ali "Strinjam se" gumb. Nekateri mislijo, da ko se na njihovem priljubljenem brskalniku nenadoma pokaže nova orodna vrstica, da je to virus. To ni res. To orodno vrstico so dobili, ker so v nedavni preteklosti kliknili na gumb "Strinjam se", brez da bi prebrali kaj piše.
