Steam: Verify E-Mail

Steam: Verify E-Mail

Today, during a party of L4D‘s new campaign “Crash Course” my pal Stealthrider suddenly disconnected. Well, I thought he just doesn’t want to play anymore but: It was worse. Some idiot hacked his steam-account. They switched his password and E-Mail. He now has to contact VALVE fixing it. Another strange thing was Zidane’s account just got hacked ten minutes after Stealthrider’s. And the frightening part now is: We all three played on the same server at the same time when all this happened. I suspect this server to cause havoc with our clients and read out the PW somehow (e.g. by downloading the ClientRegistry.blob, which stores all account relevant data such as autologin signatures)

After both got their accounts hacked (Zidane got his back, because he acted fast before the hackers could change the E-Mail. This made him able to reset the changed PW), I switched my login password and made my account verified. This seems to be a new feature of VALVE/Steam to verify an E-Mail address. After you did that, your account is bound to that Mail and if someone (or yourself) tries to change the Password,Mail or Security-Question, a Mail is first sent to your address. In it, you’ll find a link you have to click before the actions take place. This is a very good security feature in my opinion. So you all better do this soon! Right click on the Steam-Try-Icon and go to Settings/Account/Verify email address. This should keep the idiotic crackers out.

New PC set up – But having problems now (solved)

September 26th, 2009 5 comments

GFX-Card_Crash_IngameI lately wrote about me destroying my old PC’s motherboard. So I have bought a completely new PC. It’s really cool and fast. (Asus P7P55D Pro, Intel Core i5-750, Muskin 2×2048 MB DDR3, 1 TB Seagate Harddisk, HD4890 overclocked).

How it looks like, my graphic card has been overclocked a bit too harsh. I bought it at www.edel-grafikkarten.de, who generally tune cards and add additional fans. I bought this one, because it has a super silent fan and also is overlocked. But sadly, the overclocking now forbids me playing any games. After a short period of time, the game simply stops and windows tells me about a recovered graphic device. I checked the temperature of both CPU and GPU, but this doesn’t seem to be the cause. All around 40° C. So it has to be the harsh overclocking.

I think, I have to send the card back and order another one. Luckily edel-grafikkarten grants warranty on their models.

Inside of my new PC - Look at these coolers! Keeping the shit below 50°C on heavy load!

Edit:

I slightly took the overclocking of the card back. Instead of hilarious 950 MHz compared to the default 875 MHz, I have set it to 925. So far, it is stable. The ram is not OCed anymore. I fear damages on it. And 975 to 1000 ist not that much or worth for overclocking video-ram.

Bachelor-thesis submitted.

Potential of a singlebeam Dipoletrap - The uses laserwavelength is 1065 nm and the used "beamwaist" ist 10 µm.

Potential of a singlebeam Dipoletrap

I printed my Bachelor-Thesis yesterday and now it’s getting binded to a book.

I submitted my Bachelor Thesis!

The topic is “Untersuchungen zur Realisierung des optischen Speicherns von Magnesium” which is translated: “Investigation for realising the optical trapping of Magnesium”.

I characterized two highpower lasers at different wavelegths (10.5 W with 532 nm and 55 W with 1065 nm) in order to realise an optical dipoletrap in single-beam configuration. The idea comes from atom-light interaction, which is a purely quantummechanical effect. The interpretation of it is the following: The intense lighfield polarizes the atoms. The so inducted dipole interacts back with the lightfield (caused by AC-Stark-Shift), which shifts the energylevels of the atom. This effect depends on the intensity. As higher it is, as more the shift grows. If you now focus the laserbeam with a lense, intensity grows towards the focus’ position. This results into a force directed to the focus which can be used to trap atoms in it. A picture of it is on the right: Imagine it like a ball rolling into a pit. In my case, the ball were the atoms and the pit is the dipole-potential.

Disabling the Windows-Start-Sound

September 20th, 2009 7 comments

I recently found out, that the start-sound of Windows Vista and Windows 7 can’t be deactivated in the Controlpanel. I took some investigation and people offered methods in patching some systemfiles. This seems to be a really brute way.

Today I played around with the grouppolicy editor (type gpedit.msc into your Startmenu’s searchbar) and found this thing:

Computer configuration/Administrative Templates/System/Logon/Deactivate Windows-Startsound

This might not totally fit to how Microsoft called it, since I translated it from my German Windows 7 into English, but it might give you the correct path to the rules.

In order to use gpedit.msc, I’m quite sure you need a Vista or 7 Version of at least Business of Professional.

The new PC…

September 19th, 2009 13 comments

As result of me destroying my PC, I’ll buy a new one.

I first thought about buying an ASUS Crosshair III Formula board with an AMD Phenom II X4 955 CPU (150 € + 150 €). But recently, I found out that Intel has a nice CPU in this price region too: The Core i5-750. This little beast is not only faster in some special cases compared to the Phenom II above, it also takes less power (95 W max compared to the 125 of the Phenom).

I’m not sure yet, which board to buy, but it will most probably be an ASUS board again. The RAM will be DDR3 of course with either 4 or 8 GB. I’m not sure yet.

Edit:

Just ordered the following:

CPU: Intel Core i5-750

Board: Asus P7P55D Pro

Cooler: EKL Alpenföhn Brocken

Ram: 2x2048MB Kit Mushkin HP3-12800 CL9

The surprise of Windows 7

September 17th, 2009 11 comments

Yesterday, I installed Windows 7 on my 3.5 years old notebook. The new harddisk I ordered for it came, that’s why. And because Vista was slow like hell.

Well, Vista booted on it in around 3 minutes, before the harddisk stopped making noise and the PC became usable. The inital firefox start took one more minute.

The new drive isn’t that fast – 60-70 MB/s max (my Desktop PC’s HDD has 120 MB/s average and 150 MB/s max). Despite from this, Windows 7 boots up in 38 seconds – As fast as on my (destroyed) desktop PC!

Windows 7 never cease to surprise me. It’s definitely better than Vista and as fast as (or even faster) than XP.

My PC exploded

September 15th, 2009 9 comments

Today, I got my new GFXCard. I just saw, it has two 6-pin connectors so I needed a new PSU. To get the new PSU installed, I had to take out the motherboard before and take off all plugs.

Well I bought one. Installed everything find and finally switched the thing on. I heard a PSWWST sound, turned the PC off – And it started to stink.

Well, one chip burned out.VIA VT6308P.  This is chip, which controls firewire. I damaged it, because I did one fucking fault. This warning here is from ASUS:

NEVER connect a USB cable to the IEEE 1394a connector. Doing so will damage the motherboard!

The problem was, ASUS has given me some cool plug-adapters for USB and FireWire for easily adding the case’s ports to the motherboard. One is red, one is blue. And I used both to connect for USB because they are 100% similar. Sadly, i made the mistake in putting the red one in the red port of the motherboard – Which is FIREWIRE.

So I’m going to buy a totally new PC now. YATTA YATTA.

Edit:

I contacted Asus and they just sent me a mail. They are unable to test these special circumstances but also predict I should be able to use this board.

Still I’m quite unsure if I should risk it. I think I better buy a new one. I anyway were going to buy a new PC in a few months so why not to do this now.

Refresh drives, if invisible in Windows Explorer

September 9th, 2009 No comments

I recently had some issues with mounted drives not being visible or accessible in the explorer (but with any other program like notepad). The only solution I heard which works so far was restarting the whole explorer – This is shit, because I need this upon boot.

So I coded a program with the help of TrueCrypt’s sourcecode:

#include <windef.h>
//#include <dbt.h> //Just works in VS++, not in DevC++
#include "dbt.h"
#include <shlobj.h>
 
//Idea and way to do it from TrueCrypts Dlgcode.c
void SendRefreshDriveLetters(WPARAM message, DWORD driveMap){
	DEV_BROADCAST_VOLUME dbv;
	DWORD dwResult;
 
	dbv.dbcv_size = sizeof (dbv); 
	dbv.dbcv_devicetype = DBT_DEVTYP_VOLUME; 
	dbv.dbcv_reserved = 0;
	dbv.dbcv_unitmask = driveMap;
	dbv.dbcv_flags = 0; 
 
	UINT timeOut = 1000;
 
	SendMessageTimeout (HWND_BROADCAST, WM_DEVICECHANGE, message, (LPARAM)(&dbv), 0, timeOut, &dwResult);
}
 
int main(){
	DWORD driveMap = GetLogicalDrives();
	SendRefreshDriveLetters(DBT_DEVICEREMOVECOMPLETE,~driveMap);
	Sleep(100);
	SendRefreshDriveLetters(DBT_DEVICEARRIVAL,driveMap);
 
	return 0;
}

WTF roll – Breadindustry is exploiting the common people, or so

Hollow roll from inside

Hollow roll from inside

Hollow roll from outside

Hollow roll from outside

Today, I had breakfast like everyone else. Like everyone? No! My rolls are hollow! Yes, hollow.

Seriously, I think my baker tries to save some money in making hollow rolls. This hole can’t come from fermentation. It’s too big. It reaches from the upper crust to the lower crust and had the half radius of my rolls.

Here are some pictures of this shit. (Btw: I’m still hungry after this!)

Windows 7 on my PC

September 7th, 2009 6 comments

Ok, my PC now runs on Windows 7 x64 on my new 1TB HDD.

It’s incredible fast. Bootingtimes from around 30 seconds. XP took longer. Also the new HDD (1000GB Seagate ST31000528AS 7200rpm 32MB 7200 U/min SATA) is really fast too. 120 MB/s in average, 150 MB/s for peak. All in writing data on an unencrypted NTFS partition.

After encryption (TrueCrypt), I have rates of around 105 MB/s and 120-130MB/s in peak, so I loose around 15 MB/s. But I have to say CPU now rises to around 30-50% instead of <10% because of the encryption process. But I never mind. I have a dual-core (and soon a quad-core) so I don’t notice this “loss” at all. Safety by encryption is more worth. In my opinion, everyone should encrypt their drives.

Anyway, the rate-drop is still nothing compared to my old HDD (also a Seagate) with another encryption programm (Safeguard Easy). I had a loss of around 40 MB/s and rates later of 50 MB/s. So I’m lucky and I hope, finally GMod starts faster Razz
