Startup Script for Linux

akachester — Sat, 28 Nov 2009 21:41:13 +0800

Hi,

Not sure whether this is the correct place, but if it isn't, i am sorry.

I am trying to auto startup a program in Linux during every bootup. I tried creating a script and execute the script via the rc.M file in rc.d but it always shows me segmentation fault. What i tried in the script is :

./<program name here> <argument here>

but everytime it just shows me segmentation fault. However, when i tried to execute the script manually by doing ./<script name here>, it works fine. It just wont autostart by its own on bootup. Anyone had any idea how to create those scripts or perform this autostart during bootup?

Thanks.

Get current time

akachester — Mon, 09 Nov 2009 17:21:11 +0800

Hi guys,

I need some help here.

Had a program that can actually read the current time from the CPU via this :

CODE

gettimeofday(&tv1, NULL);

Now, from there, i can get the time in seconds and microseconds.

CODE

long seconds;
long useconds;

seconds = tv1.tv_sec
useconds = tv1.tv_usec;

My problem here is, i am trying to get it to have 100ms mark later than the supposed time. This is in order to predict the time my operation will finish (i assume my function will finish within 100ms). Is there a way to actually get the time exactly 100ms later? Can i do something like :

CODE

useconds = tv1.tv_usec + (100 * 1000);

to actually get the useconds to be exactly timed 100ms than the current time? I am afraid that the tv_usec would actually be overflowed and reset itself (increment the tv_sec parameter by itself). Is there a way to actually do this continuously without a problem?

My actual program would look like this :

CODE

long seconds;
long useconds;

gettimeofday(&tv1, NULL);

seconds = tv1.tv_sec;

while(1){

useconds = tv1.tv_usec + (100 * 1000);
printf("100ms later is [seconds : %ld] [useconds : %ld]\n", seconds,useconds);
}

Thanks.

Sending CTRL+Z in C Language

akachester — Thu, 22 Oct 2009 16:35:27 +0800

Hi guys,

I am currently trying to create a function to send SMS via AT Command using C language. And in order to complete the SMS, the AT Command / GSM Modem would need to detect a CTRL+Z. I am wondering, is it possible to include a CTRL+Z at the end of a string? And how could i do that? I tried sending it by ending it with an ASCII code of CTRL+Z but it doesn't seem to recognize. Anyone have any sample on this?

Thanks.

Delete Proxy Setting

akachester — Thu, 23 Aug 2007 15:48:05 +0800

Guys,

May i know does anyone know how to delete proxy setting installed in a PC?

I had installed a proxy setting into a PC via a .reg file which automatically install the proxy setting.

My problem is, after installing the proxy registration file, there are some sites that are blocked from being used. However, by manually setting up the proxy setting in the LAN (by typing the proxy setting on my own), there is no such problem. Therefore, i needed to know, by any way i can delete the automatically installed proxy from my current PC?

Thanks...

Frequent BSOD Problem

akachester — Wed, 25 Jul 2007 18:15:12 +0800

Hi guys,

I am facing a problem here. Lately, my Dell laptop had been facing frequent BSOD problem and need me to restart PC everytime it happens. This is what displayed when the BSOD happens :

A problem had been detected & windows has been shut down to prevent damage to your computer.
...........

Technical Information:

STOP X 0X0000008E

Win32k.sys - address BF8E5F91 base at BF8000000, DateStamp 45F013f6

Its actually a very long winded error code. If what i get there is not related, do let me know so i could copy the whole error message out for clarification purpose. Anyway, the BSOD only happens when i tried certain programs like SQL Server 2005. I do feel it MIGHT be due the program needed to use a high amount of memory and causes the program to BSOD. Thus far, only the SQL program is causing this problem. I already tried reformat, reinstall drivers, reinstall SQL and its still the same. I do not feel the software have any problem as many of my colleague is using them as well without any problem. Do you know what might happen here and is it due to hardware defect?

I am still waiting for confirmation from Dell though...

[Help] Kia Spectra Air Conditioning

akachester — Tue, 03 Jul 2007 08:34:49 +0800

Hi guys,

First of all, sorry if i posted this in the wrong section as i had never posted in this section before. Please do inform me if i have done so..

Anyway, this is my problem and i hope some experts here can help me solve it. Last week, the battery of my car suddenly went 'kaput' on me and i had to replace it with a new one. As normal, some of the electronic stuff will be set back to default. Anyway, after i had changed the battery, the is something wrong with my air conditioning control.

In the middle bay of a Kia Spectra, there is 3 buttons which is : AC On Button - Outsite Ventilation Button - Inside Air Circulation Button (Sorry if i use the wrong term). Basically, by default before i change the battery, both the AC On and Inside Air Circulation button will be turned on everytime i start my car. When i changed the battery, it suddenly changed to AC On and Outsite Air ventilation by default.

This makes me needed to manually switch it from Outsite to Inside Air Circulation everytime i start my car. Is there any way to fix this problem?Can i set the Inside Air Circulation Button as default ON instead of the other one? Hope you guys understand my question here..Sorry for making this so complicated..LOL...

---------

One more question, anyone knows where can i get a specific Car Owner's Manual either via eBook or the hard copy version? I am specifically looking for the Toyota Levin AE101 SilverTop manual for a friend of mine (either manual or engine tuning manual). If anyone can point me to a direction on where can i find them, i will appreciate their help..

Thanks alot to all the sifu here...

Keyboard Typing Problem

akachester — Thu, 28 Jun 2007 11:58:49 +0800

Hi guys,

I am having a weird problem recently (OK, its not on my PC but its my dad's PC). What happen was, when i am typing something using the keyboard, sometimes, the character does not comes out.

For example, if i press A B C on my keyboard, only A and C will come out and the B would be missing. This does not happens on specific keys but on most of the keys as well. Typing speed is normal, not those ultra high speed typing. May i know what might be wrong there? Thanks..

Cheapest Broadband Combination

akachester — Fri, 08 Jun 2007 23:56:54 +0800

Hi guys,

I am not sure where to put this and if this is in the wrong subforum, do inform me or help me move it ok. Thanks..

Anyway, this is my question..

I am about to shift to a new place and was looking forward to get myself a broadband line. Anyway, after some consideration, my mind is only having the Streamyx as an option. However, considering the fact that i need unlimited package, i would need to pay at least RM66 + Telephone Rental bill every month which almost equivalent to RM90.

Anyway, i am wondering, is there any other cheaper solution available for unlimited broadband connection?Is there any other choices available to consider in the same range as well?Thanks alot for the help...

Flickering Screen

akachester — Thu, 10 May 2007 19:39:25 +0800

Guys, I am in need of urgent help here..Almost getting crazy because of these..

Ok, previously, i had posted here regarding a flickering problem that i have been having my with computer and after a long time of help and researching, i know it is a problem caused by my GC. Something to do with artificats on the card. Tested it on 3D Mark and it had proven it..

And i thought it was already fine..Until it encounter another problem just now. This time, i am using the Palit 7600GS Sonic instead of the already dead 7300GT and i am pretty sure there is absolutely NO PROBLEM with this card. The reason i am saying is that this card belongs to my cousin and there is no problem at all when i use it. And this flickering problem also exist during the usage of my previous 7300GT but it happened only once..This is the 2nd time it happened..

I really wanted to know what might cause the problem here and i am really getting crazy problem persisting after another..

This is the flickering i am talking about:

There is absolutely nothing else i can do when this appears and the only thing i can do is restart and the problem is gone...

[WTA] Pricing For Hardware

akachester — Thu, 10 May 2007 19:13:41 +0800

Ok guys, i in need of help in term of pricing here. There are a few things that i would like to ask. Therefore, i will seperate this into different part. Please do let me know what do you guys feel the price point will be. Thanks alot...

-----------------------------------------------------------------------------------------

First of all, i got a 2nd rig (not a full rig) lying around collecting dust and i am sort of thinking of selling it to a good friend of mine. However, i do not know the price that i should offer him now. Please do let me know the price that i could offer him on these specs:

Processor : AMD Athlon 3000+ Venice E6

Motherboard : Gigabyte K8N SLi

Casing : Cooler Master Centurion 5

PSU : Cooler Master Real Power 450W

GC : Galaxy 7300GT 128MB DDR3 (Currently on RMA)

Actually, there is a few points to consider here. First of all, my friend is not an experts when it comes to computing. All he wants is a worthy rig which are not overpriced. Anyway, if you guys are helping me out in qouting a pricing in this rig, i hope to keep in mind that i really need to OFFER him a price that he couldnt resist (of course not ridiculous one like RM50 ).

I know AM2 is running on dirt cheap price now and i hope the price that i could give him on these obsolete S939 spec would be cheap enough to attract him and in the same time, does not give a huge loss to me..Thanks...

--------------------------------------------------------------------------------------------

Secondly, i would need to get a replacement GC for the spec above as the 7300GT is still under RMA and i do not want to sell a PC which are still not able to run. Therefore, i wanted to look for a replacement which will be:

The Cheapest PCI-Express GC currently available in the market AND its price

I really need to know which would be the cheapest available regardless of spec and it MUST be brand NEW..

------------------------------------------------------------------------------------------------

Finally, i am thinking of upgrading my rams as well and since i already fully utilized my 4 ram slots, i am thinking of selling off my current rams as well. Well, i am still in the process of "THINKING" until i have the budget to get a replacement..

Anyway, how much do you guys think these rams will be able to fetch in the current market?

2 * 512 Corsair TwinX PC3200 Pro Led (3-3-3-8)

2 * 512 Corsair XMS PC3200 C2PT (Rated 2-3-3-6)

Thanks alot for the help..Appreciate them...

Graphic Glithes On My Computer

akachester — Wed, 25 Apr 2007 19:06:36 +0800

Alright guys, as the title above, i have a problem in graphic just now. This is what happens:

I was enjoying myself with the C&C3 just now, trying to test out which setting will work best on my 7300GT. Everything was fine and as happens during the gaming, there are some part especially those that require intense lighting seems to be flickering slightly. I was ok with that but still looking for setting that might reduce it..

Anyway, all of a sudden during the game, glitches started to happen. My screen was flickering with black dotted lines all over. And i thought i had mistakenly set something on my C&C3 setting. Therefore, i decided to exit the game and heck, even the same is happening on my desktop. I was worried that it might be some problem with the temperature but no, its normal running at about 52c.

The reason i am worried about the temperature is that i took out my GC HSF yesterday to replace the TIM. When i changed it from the AS5 to the TR Chill Factor and boot it up, it started at a crazy 63c on my GC. I was afraid something might go wrong and i replaced it back with the AS5 and its normal again at 50c ..

What might go wrong with my system?My best bet would be a problem with the graphic card but i did NOT do any Overclocking in it.Running at default speed of 500/1400..

This is the examples of what happens..Even restarting does not fix it. I turn the PC off for a few minutes, and turn it back on, then only the problem dissapears and now back to normal ..

Please help me identify the problem..Thanks...
