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.

Bulk Saving Images Encoded As Base64 Anonymous 16/02/10(Wed)20:50 No. 22045 ID: 78a278 [Reply]

File 145513380213.jpg - (8.35KB , 225x225 , help.jpg )

I have about 400 html files that contain images encoded in base64

<img src="data:image/svg+xml;base64,[really ass long string]">

I need some way to save these images as individual files. Yes, I can save as in my browser (firefox), but only one at a time, and there are 400 pages with as many as 100 images each. Page Info/Media also works, but only for one image at a time, selecting all and hitting save does nothing. So unless I can find some bulk method that will work with base64, I'm looking at a really, really long slog through this mess. Any help or advice would be greatly appreciated.

Is there a way to extend a router's signal using two wireless routers without having the 2 routers connected?
Everything I seem to find seems to require the two routers to be attached via cable.
I (hopefully) want one wireless router to "repeat" the signal in a long basement apartment with shitty coverage.
The guy who has the base router and modem in his room is a bit of a bitch about having any cables going out of his room.

The reason a wired connection is used is because if you're stupid enough to do it wirelessly, you cut your bandwidth in half. The radio can only receive or transmit at any given time, it can't do both.

Try connecting them via powerline networking. It turns your wall plug into a Cat5 (or 6, if you're naive enough to believe wireless signalling rates are actual data transfer rates) run.

Only if it supports a repeater mode. Can be easier to buy cheap range extenders, although keep in mind this only fills in gaps and you do lose performance. Many older routers only work well with certain models of their own brand too.

The main router nor secondary routers need to support repeater mode if you string them together via cat5. All you have to do is give the two routers the same name, same encryption method, same passkey, and disable DHCP on the secondary router.

So I was browsing my good old ISO folder today and noticed that I had an ISO of ReactOS.
I wondered if it was still being developed, but to much of my surprise the project looks dead.
Does anyone know more about this?

Its still not useable for most things. hardware support is rough at best. Interesting if you develop, but its not like you can throw this on an old system to replace XP or something.




cloning a system drive with multiple partitions. Anonymous 15/10/26(Mon)11:40 No. 21958 ID: 776200 [Reply]

I have pretty much decided that despite diagnostics I am going to upgrade/ get a bigger system HD. I'm just not sure where to begin.
I am using Windows 7.
The whole drive is like 500 Gigs and is in 3 partitions a 230 meg system drive.
A 100 meg system reserve partition that the system added during a migration to my current motherboard.
And a 250 meg partition (no this isn't all my storage space I have 2 other drives I added afterwards)
If it was just the partition with the system drive I Think I would just have to just create a System Repair Disk on a USB or something and then a system restore on the new drive. but that's only for one partition.

How would I go about partitioning my new drive to keep the current partitions (and Data) but resize the system and storage drive?
I feel like a bit of an idiot asking but really woudl like to do this myself.
If someone could spell it out in a moderately spoon fed way or point me somewhere to find this?

- or could you clone the whole drive on a larger drive and then fuck around with it with partition magic etc. ?

It should proportionally expand all non-system partitions on a disk if you follow the instructions on that link. Obviously if you have whole disk/partition encryption or the like enabled then all bets are off, since it won't be able to interpret the NTFS directory structure to expand the partition.

Personally the last time I had anything beyond system & boot partitions on a disk was when partitioning was the only means of controlling the block size. Controlling the block size meant you wasted less data, because a .5K file still occupied however large the block was, and smaller partitions had smaller block sizes. These days the block size is normally 4K (unless you go out of your way to change it) no matter how big or small the partition is.

Anonymous 16/02/07(Sun)19:41 No. 22042 ID: 3d0318

Use Clonezilla to image/copy the drives, then GpartEd to move and resize your partitions. Gparted is non destructive, but you can make resizing multiple partitions really slow if you dont think about the order of operations first.

I have a nexus 7 tablet and I run into the eternal bullshit of "insufficient space " when updating this bitch of a thing. I've used 2 cache cleaning programs, deleted a game that took up a GB and still can't update even facebook.

Any suggestions that don't involve hurling this thing into a lava pit?

Yesterday, my Dell Precision 390 had issues starting up. I got some kind of error message that spoke of the keyboard and some kind of heating issue. I hit F1 and it worked as usual.

Then today it won't start at all. The fans in the PSU just goes "woom", the lights in the front flashes and the computer flatly refuses to boot.

Please help. Is there some kind of fuse on the PSU etc that I should reset?

Technically it's a case of heat (expansion) and cold (contraction) physically moving parts apart enough to create problems. This is why 360s got a RROD, heat, contract, heat, contract, crack, RROD.

You'll still get heat/contract cycles, since even with a cooler the RAM slot will not be as cold as it is when the system is off.

It's a difference of inches vs. feet, so while the problem will still occur, it will occur more slowly.

Boosting router signal.
I got a new router and it has an internal antenna and it seems to have much weaker signal strength/ range than the previous model I used that is about 7 years older.
It's a D-LINK DIR-820L.
it has no place outside for an external antenna but I was wondering if I could boot the signal
with something like a USB WIFI Wireless Adaptor network card or something like this?

Any suggestions?

The problem with this thing is it has NO external antenna.
It *does* have a USB port however.
- which is why I mentioned the other USB antennas.

It is new but I actually got it a few months ago and never hooked it up.

It doesn't have an external antenna. It does have an internal antenna.

Sticking a reflector behind it can't do any harm so you may as well try it.

Oh. That's what you meant. No, you can't plug a USB NIC into the router and have the router use the NIC. You could use the NIC with your desktop or laptop to get better reception there.

I feel your pain about unused purchases. Last month I ordered a piece of equipment and had it shipped to another site for a coworker to use since he said he desperately needed it. I asked someone to go into his office today since he was out and we needed something in there, and the shipping box was sitting in there unopened. Well, we could use it, so I had it brought over. What do I find? Straight out of the box one of the power adapters is broken. Something we could have had replaced for free if he'd have opened the box when it came in or shortly thereafter, not six weeks later.

A reflector, so long as it's tuned for the RF ranges in question, could certainly work, although it will also result in a completely dead spot behind the reflector.

By way of comparison, with an N66, I can join from over 100ft away. Keep in mind an entire apartment building is sitting between those two points. As in, I'm in the corner of an apartment building, there's a dividing section (walkway, grass, etc.) between buildings, and on the other side of the other side of that building I can join my network. And there's wireless networks in that building, plus all around me. This is the power of good engineering though, as others have pointed out, properly choosing the correct channel(s) for your network is key given your surrounding. Only by walking around with a WiFi surveyor can you get a decent sense of how the WiFi networks look, though you won't see non-WiFi intrusions (security cameras, baby monitors, cordless phones, everything that uses 5Ghz & 2.4Ghz that doesn't use the WiFi standard to connect).

I have had the same issue, and ended up paying $40 for a pair of durable earbuds on amazon, and it was shipped with an already broken earbud. I might try these ones myself.
