A few things that might help get those questions answered faster.
Be specific when you are talking about something - "my mp3 player is broken HALP!?"
- What kind of mp3 player, (brand and model)
- What isn't is doing now that it was before (the reason it is "broken")
- What were you doing to it last, right before it broke.. Did you maybe drop it?.. get it a little wet? try to flash the firmware?!

These all help in determining what can be done.
These rules do not just apply to MP3 players.
Just be as specific as possible and don’t leave stuff out, we want to be helpful here, try not to make it a scavenger hunt for clues!
These same rules apply for other situations like “I got a new motherboard and now my computer doesn’t post!”
-old motherboard model
-new motherboard model
-ram (speed)
and any other component you might have in there (most of the other stuff usually won’t matter but list what you know.

I don't know if it's still the case, but back when I was taught electronics they covered house wiring as part of the curriculum. I'm going to guess they don't do it anymore, because everyone younger seems shocked that a geek like me knows house wiring...

couple questions about computers

1. what is the cause of older games not working on more modern computers? is it because games are designed for certain OSes? or is it a hardware issue?

2. i've heard programs designed for powerpc macs won't work on intel macs. why? (just asking, i don't care really because apples are for faggots). if software is dependent on cpus, are there programs for pcs that won't work for amd machines?

remember to enable it in the BIOS too, otherwise the emulator won't be able to use the hardware. (in microsoft virtual PC 2007, you have to enable it in the settings too - enable hardware virtualization box is unchecked by default, so you have to check it)

on my older BIOS it says
1. intel virtualization technology
2. intel VT for directed I/O)

More importantly different processors imply different microcode and different microprogramming

Hey /halp/, i have a technical situation that i don't really understand.

So my dorm has its internet coming from one central router, and this router is configured to block internet access after 12AM.

With most websites it simply shows me a html block page with the option to submit a password.

Just running tor at standard settings doesn't help, cant establish connections to dir servers.

This is where 7chan comes in....

For some reason i can ALWAYS connect to https://7chan.org, im supposed to be blocked right now, but clearly im online and able to browse the website.

Any tips on getting past this router block?
As computer savvy as i am, i just cant understand how to brute force the password, which i would have tried.

Ive tried that in the past, and its true i can connect to other certain https websites like google https, but issues arise when they load items from a non https source.

For example:
http://www.gstatic.com/generate_204

A common resource 7chan and 4chan try to invoke, but luckily 7chan still works without it, albeit slowly.

Or with google, i cant open any links, and just slapping https on the front never works.

Many https sites simply dont load at all.

Okay, will take a look.

Can you explain why do you (highly) recommended MSSE so much? Is it because microsoft must be understand lacks in their os better than third party (and find ways to fix them)? Or other reasons?

Security Essentials is a third party product, GIANT Antispyware, that Microsoft acquired and turned into MSSE. It's got a very low CPU hit for a real time scanner, definitions updates are released daily (including weekends, and sometimes multiple times a day), and generally it works as well as GIANT Antispyware worked.

That being said, you really do need to rely on multiple AV products to avoid getting infected with malware that can hide from the particular AV product you have installed. By relying on multiple products, you have a lot of functionality overlap, but also each product will do unique things that make it harder for malware to hide from every AV product.

However if you install multiple real-time scanners you'll quickly regret it, since every time the system reads a file it's got to wait for the real-time scanner to intercept the read, check it for viruses, then let the system start reading the file. Real-time scanners don't work in parallel, you'll have program A reading file A, then program B reading file A, then program C reading file A, then passing it off to the system so it can read file A. And Windows constantly reads and writes files, so you need your real-time scanner to work well and efficiently. MSSE does this effectively on everything except the lowliest of netbooks and 1990s systems (OTOH up until a few months ago I had a 1.4Ghz P3 that MSSE ran perfectly fine on).

The reason I like MSSE is simply because it's adequate for AV protection and the real-time scanner works very, very well on anything approaching a modern system.

It's not perfect, malware authors certainly include it in their target list(though they are more effective at targeting Avast and AVG - you may as well not install either for all the protection you'll get from them), but it gets regular definition and program updates that trip them up. You'll want to enable the "update Microsoft software" feature of Windows Update to automatically install its program updates.

Still, you will want to have MBAM and other AVs installed in a scan-only configuration, since no single AV program is perfect (there's a very good argument being made that AV programs, which are a blacklist system, are on their last legs and only whitelist systems will survive).

Another tool to look at is CryptoPrevent, which configures the software restriction policies built into Windows to stop some types of malware. The idea here is to have overlapping defenses so that even if they penetrate one, it doesn't necessarily mean they'll penetrate everything you have. SRPs can be very effective so long as they're configured correctly.

Your friend is a dipshit and should stay away from computers.

A failing motherboard may cause an incident of data corruption, but it's far more likely to be flaky in other ways too. There are various small form factor business Dell models, like the gx280, from the Pentium D era that ran way too hot. Capacitors would burst on these, and you would experience random slowness.

There's really not a specific thing that points to a failing motherboard other than it won't power on when nothing but a known good CPU, known good RAM, and known good PSU are connected. Generally one arrives at the conclusion of a dead motherboard by eliminating everything else, or physically seeing damage.

In any event, a failing motherboard has nothing to do with the amount of data your operating system can handle, and the condition of your motherboard does not affect this one bit.

Kindly go into details on what is happening when you access this hard drive (does it show up in the BIOS setup menu? do you have a known working system that you can connect it to, what type of hard drive is it, etc.) and I can provide some advice.

Whats currently the best free software for cleaning up a Windows 8.1 PC?

Kinda just got my new PC up and running for a month now and was a bit unsure on what i should get to clean out registry errors, spyware and all of that general stuff its usually good to run trough each month.

So thought i should ask what people recommend, I use to run CC cleaner and Malwarebytes on my previous Windows / PC and that served me well enough.

Those people you are referring to just have shitty habits though. They are probably going to Ask Jeeves and typing "how can I make my computer faster?" so of course they just get bogus programs bundled with viruses. You say CCleaner is an exception, but this is just an example of a standard (legitimate) cleaner. I guess some people just don't know the difference between something like Penis Pill Popup Program Pro and legit software like CCleaner.

That said, OP, you don't need 50 different programs that do the same thing. Since your computer is new, though, I'd run PC Decrapifier on it, and you could also look at Glary's Registry Repair and System Mechanic.

No, they're just installing crap like "Advanced Uninstaller" and similar products that have what's best described as definition files. After you run a program's uninstaller, you tell the "cleanup" program what program you just uninstalled and they - based on the definition - walk through your drive removing files it "knows" the installer left behind. Any other piece of installed software that also used those files ends up hosed.

CCleaner doesn't do anything like that, the worst it does is it walk through the registry looking for files that are registered but aren't present at the registered location.

I do two things. CCleaner is nice for the temp files windows stores up, but know that doing this can impact your performance, same as clearing your cache. It's still worth doing, imo, cuz windows can really stock up on all the temps. if you use something often, just uncheck it from CCleaner.
Other than this, I periodically open up my Add/Remove Programs. I have it sorted by date used. I scroll through it, looking for names I don't recognize. If there are programs that I've not touched for a month then they are likely to be removed.
just stay on top of your shit. it's like keeping your room or kitchen clean

I am just looking for a point in the right direction...
I would like to mod my xbox to play backups from a usb. I have been finding plenty of guides but they don't quite seem to match my goal. A lot of time and trouble is spent being sure you can take the system online once again. Well, I'll not be paying for gold and have no interest going online, I would just like to play any game. Any idea, phrase or site to reccommend?

The long of it: I got a launch xbox, it actually didn't RRoD for three years. Finally went down, sent it in and they refurb'd it and that worked for another two or so. It red ring'd again and I just didn't care anymore. I had it packed away for over a year. Then i took it apart into its components, threw the case away, and have been toying with the idea of submerging it in oil to keep it cool rather than trying to fix the air cooling for another try. I am at the precipice, I have the oil and the container and the pump and the radiator. I am ready to plunge it all into the liquid except that I don't want to pull it out and clean it if/when I need to reroute some points with some wires. It seems like JTAG is my answer (I know how to flash my drive, but that only allows backups of the DVD variety, which I will do if I must, but is less preferred as it still requires some media) BUT JTAG requires a dashboard level of some very old version or even older. MY dash is past this. search and search, I cannot find how to reset my mobo and delete the updates. Wiping the HDD is not the same. The data is stored on the box somewhere.
Anyway, I'll be updating to respond to you all and to add what I find. Not sure if this is quite the right board, but it's definitely more appropriate than /b/.

Hello people of this board all the way from Mexico! I have a huge question and I was hoping that you fellows could provide me with some insight on what to do here, please.

As some of you might know, our government approved the law Telecom (old news, but I’ll leave a link with more info here: https://www.eff.org/deeplinks/2014/05/proposed-mexican-telecom-law-would-be-disaster-internet-freedom ) which basically means three big things:

My internet service provider will monitor all my activities (from now on all ISP check their customers).
My ISP will have a 2 year data archive of everything i do online and can check it whenever it feels like doing so; &
In case my ISP finds anything that the government dislikes (such as bad-mouthing the president or arranging a pacific protest) it will inform the authorities and will be arrest any suspect without a judge’s warrant.

As someone that likes to occasionally likes to lurk in /ss/, /cake/ and into sad panda I was wondering what measures I can take to be able of surfing these pages without having to worry to get caught (as a safety measure, I’m posting this from a cyber café).

Please, if you can, help a bro out, trying to explain as much as you can in layman’s terms (my English is not that good) and I needed an answer compatible with Mac (yes I know Mac is shit; just bear with me on this one as I have to bear with it) and PC. Thanks in advance for your help! Hope you can offer some insight of what can I do =D.

In theory SSL should protect you from casual observation. However SSL can be cracked, even somewhat easily if the server isn't using PFS (which requires substantially more CPU time for the server, since basically every connection to the server gets encrypted using a different encryption key, which takes CPU time both to generate and to use).

What you could do is use a VPN service, which can use cryptographically stronger keys (making it harder for your ISP to crack) between you and the service, making your ISPs captured traffic less useful. This service also needs to exist outside of your country, otherwise you'll just be shifting logs and enforcement to the VPN provider's ISP. VPN connections can still "leak" data to your ISP about what you're doing, particularly using DNS lookups, however this is a well known problem so some VPN clients and/or client configurations can make this less of a problem.

Alternately you could use Tor, but that's increasingly likely to get you red-flagged as a terrierist and/or child pornographer.

Pretty simple question. I want to make a few YouTube vids which consist of just an mp3 with a static picture tacked on to make it an actual movie file. Windows Movie Maker sucks because it can't understand .mp3 files, and converting the .mp3 to .wma adds popping noises, regardless of what method I use to convert it.

I've seen programs out there for making movie files, but I'm not sure what's a virus/needs money to work, etc.

okay so I went with your suggestions and I've been looking up this unknown random app stores on the net but they all require me to have an icon that's 100 x 01020 pixels exactly and other banal shit that I can't be bothered doing.

My motivation at this point is just to publish it so I can delete it from my usb and never think about it again. It's a really basic app (literally made in flash then adapted to apk) but it's useful for specific technical applications. My secondary motivation is I can include having developed the app on my resume to make myself a better candidate for some things but if I have to prove I want to be able to point to a published place and go HERE IT IS!

Are there any places I can just dump the apk and it have a chance of being found by people looking for apps without having to jump through shitty hoops.
