Extending RJ11 (Phone line)

othniel91 — Wed, 28 Oct 2015 11:49:32 +0800

Does extending the RJ11 cable say 50 meters deteriorates the line? As in from the wall port to the router 50M. Doing some reorganization of routers placement, not sure if it will lose signal or increase attenuation and decrease the SNR margin.

Googled but this is as assuring as I can find: Ars Forums

But i need some network eng/tech to confirm this or If anyone run this type of configuration before, obviously I want to LAN my router instead of using wireless and CAT5/6 cables are way expensive then phone cable.

Thanks in advance

Hacked? or just power failure?

Contract of Service vs Termination of Service

othniel91 — Fri, 13 Jun 2014 08:55:01 +0800

Say the Contract of Service is 2 years and Termination of Service requires 3 months notice or pay 1 month penalty from either party that decides the termination.

What if next month my contract ended and I would like to resign voluntarily without renewing my contract.

Do I just write the resignation letter contains notice of one month (or less like 1 week) or would that course of action breach my contract?

PS: I know I would have better answer if I ask HR (my dept actually) but I'd prefer to ask here instead :|

C Programming - Storing String in Structured Array

othniel91 — Mon, 02 Jun 2014 10:19:42 +0800

Why I can do like this:

CODE

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

struct record {
char name[50];
float marks;
};

void main(){
int x;
struct record results[50] = {"Ben", 77.10};
for
for(x=0;x<50;x++){
printf("Name: %s\nMarks: %3.2f\n", results[x].name, results[x].marks);
}
}

See the: struct record results[50] = {"Ben", 77.10};

But I can't do it individually, example

results.name[0] = "Ben";

or

results[0].name[0] = "Ben";

or

results[0].name = "Ben";

However for real data type and int can, example: results[0].marks = 77.10;

I'm not expecting straight answers, give me a clue or tip would do! thanks!

Forward US IP to MSIA IP

othniel91 — Thu, 29 May 2014 15:09:41 +0800

This is my situation, not sure should I post here or Networking section. I have a linux admin cert but never learn IP Tables or NAT, so bear with me.

I am running a 2 server, a dedicated which is in Malaysia and a VPS which is located in Seatle, USA.

Aside from other service that the dedicated server is running, among them is a web server, what i want to achive here is like this:

Public visit Domain (example.com) which the DNS (cloudflare) points to the US VPS, then fetch the web content from Msia Server. I'm not sure how to explain as simple as that, its like I want people to not access directly to the Msia server, but through a proxy site which represents the dedicated server.

I've googled and not sure if IP Tables is my solution? Not asking for a copy paste answer, just a quick tip or guide to help me steer the right direction.

Details (IP is not real for security purposes)

Dedicated
OS: CentOS
Dedicated IP: 101.127.90.1
Listening Port: 80, 443

VPS: CentOS
Dedicated IP: 221.51.31.90

Neigbour using spray machine

othniel91 — Fri, 19 Jul 2013 21:58:13 +0800

I have a neighbor who once in a while spray his car using a machine, the problem is, it gets very smelly and sound from the machine gets very disturbing after quite some time, I'm thinking of reporting it to the authorities because previously he was doing it in the evening which I wouldn't mind but now he does it even at midnight!

I've skim through the Act 127 of environmental quality, it did not mention of air pollution from spray in particular, I wouldn't want to make a report and fail which will make him retaliate by doing it more often, i want to make sure it stopped once and for all.

A neighbor across the street did talk to him once but it did not work, if anyone were to take the blame after the report it'd be him

Anyway is it illegal and against the law? I live at a residential area, a terrace house with no management, basically i only have Dewan Bandaraya to complain to...

Old PC Upgrade or Buy New? For home server

othniel91 — Fri, 05 Apr 2013 12:18:54 +0800

I have with me an old am2 sempron processor (Sempron 3000+ Manila), It's been kept idle back in the box since 4 years ago. I'm re-purposing it to be a home server because I'm in need of one. The server for all intents and purposes is goinng to be a simple LAMP server, it wont perform intense cpu task. The problem is that the previous board is faulty (capacitor problem and southbridge overheating problem) but the parts is such as DDR2 RAM (1GB x2) 160GB HDD are in good condition. So now what's between me making it into the server is the motherboard.

Before going to my dilemma of options, my main question is which options will be more worth the money that fits my purpose of a home server? especially in terms of power, performance and cost.

Option 1:
Buy a new board: Asrock N68C-GS FX Supports DDR2 and DDR3 AM2 - AM3+ = RM 160 or so

Option 2:
Raspberry Pi + 8GB CARD = RM 190

Option 3:
Intel Desktop D2500HN w Integrated Intel Atom Processor Motherboard = RM200
*I have 2GB DDR3 ram

I'll rephrase my question once more, considering my budget of RM 300, I'm intending to get myself a personal home server. Which one of those option above will be more well suited for this purpose? I am yet to decide yet because every one of those option are presumably good enough, I need another persons opinion on this. Thanks

Installing RAM from 2GB + 4GB

othniel91 — Thu, 16 Feb 2012 00:36:58 +0800

When I bought my system, it had 2GB RAM installed, but I am running on W7 64bit and I would like to get the most out of my system, but getting the same model of 2GB is rather a waste of cash and will only disrupt my plans for future upgrades. So I thought of getting 4GB first and maybe adding it up later on if I need to, so here's the problem, will there be any memory conflict in installing 2GB + 4GB RAM DDR3?

How much Watt PSU Recommend for My Build

othniel91 — Tue, 14 Feb 2012 11:29:41 +0800

I am using

AMD Athlon II X2 260 (65 TDP)
Sapphire HD 6570 (Low profile card, non 6pin powered)
an ATX Mobo (24pin)
1 DVD Drive
1 320 HDD

No casing fans

So what wattage suitable for this? I'm currently using Cooler Master 500w but my problem is that I always keep this machine on everyday and figure out that 500w would hurt my electricity bill if this keeps going on.

Thanks and awaiting reply.

EDIT: I'm not into overclocking.

Opinions on this Poor Gaming Built

othniel91 — Thu, 02 Feb 2012 12:40:17 +0800

This will be super low budget gaming system (Budget: RM 500-700 for CPU, Motherboard, RAM and GC) and I have come out with this built:

CPU: Intel Pentium G620 2.6GHz or AMD Athlon x2 260 3.2 GHz
Motherboard: GA-H61M-S2-B3 (Gigabyte)
RAM: 4GB
Graphic Card: ATi RADEON HD 5770 (Thinking of getting the one from Gigabyte)

I know with this built could at least play the latest game such as Serious Sam 3 or Skyrim at low/med settings with acceptable frame-rates. So, I'm not asking for recommendation but opinions, as I myself am not an expert in hardware comparison and benchmark, I've done research but couldn't get the "YES IT IS GOOD" satisfaction, so thought I shoot this in the forum.

So the real question (Just in case you guys confused with my poor grammar)
1. Is AMD Athlon x2 260 which have 3.2 GHz is more beneficial than this Intel Pentium? In terms of gaming not video encoding etc.

2. Is there any other Graphic Card that are a little/lot better than the one mention in that price range or category of budget gaming cards?

3. Have anyone ever owned or have this similar built? Or at least voiced out your opinion, if you think it is rubbish say so, if you think it's totally outdated say so, I wouldn't mind harsh opinions.

2.5 HDD to Desktop

othniel91 — Tue, 31 Jan 2012 19:51:13 +0800

I would like to know if the 2.5 Hard Disk (that was directly taken out from laptop) can be used on the desktop? As it has similar connectors like the 3.5 HDD. Anyone tried it out?

Lowest Entry CPU Recomendation

othniel91 — Thu, 11 Aug 2011 19:28:45 +0800

Need a pc recommendation, getting this for my mom's friend =,=!
The thing is the budget is RM 700, and I been sourcing around all I can find is RM 900 and above, anyhow I don't know much about the latest hardware and price in the market so I need some help. LCD screen, keyboard, mouse and speaker no need, just the computer system, nothing fancy.

These are the important needs:
1. Able to run web browser without lag
2. Able to to open Microsoft office without lag
3. Able to run windows xp

If you can fulfill these other needs is a bonus:
1. Able to play really low-graphic games like dota, counter strike, starcraft: brood war, diablo those.
2. Able to play movies (hd is a bonus, but if can, SD videos could be played)

Sorry for the limitation, I even tried to built a Intel Atom but then, from my experienced of a netbook before, it's not suitable as there's always casual lags. I was thinking Athlon or some sort. So anyone mind helping me out ?

Take your time, maybe end of this month will buy it.

Building a Home Server 3k budget

othniel91 — Sat, 16 Jul 2011 22:52:32 +0800

Usage:
It's a home business server.

Type of server usage:
1. Email
2. Web Server
3. Database

My budget is RM 3 000 but can go up to RM 3.5k if needed. I want to use be Intel i7 960, but if anyone could suggest to me something better I would consider.

So what recommendation I need is:

1. Motherboard (if can have future upgradable options and power saving too if possible)
2. RAM (Clueless, should I go with KVR or get some gaming RAM that have heatsink?)
3. Hard Disk (I need to run on RAID 1, so a good performance drive not ssd, capacity of 1TB)
4. Casing (It must have good cooling system as it will run almost 24/7 most of the time)
5. Third Party CPU Fan
6. Power Supply that can power all these, if can have more power cable for fans
7. Also a UPS.
8. Any other thing that I've missed out?

The rest such as optical drive, keyboard, monitor, etc is not included in the budget so just focus on this first. Help me out ya, pretty urgent as I need to get all these by next week.

Oh the OS I'll be running is CentOS 6 64bit.

Edit: Can i use built-in graphics from motherboard? I don't think 960 have built in graphics.
