How can cropping images make the file bigger?!? (6)

1 Name: Artist : 2013-08-17 21:40 ID:QfDEDDc+

For some reason sometimes when I crop an image to reduce the file size the opposite effect happens and the file actually gets bigger? How does this happen and can it be avoided without affecting the picture quality?

2 Name: 4n0n4ym0u5 h4xx0r : 2013-09-01 12:02 ID:2K9ioN4N

Sounds like a format change. Maybe you cropped a png and saved as jpeg? Or maybe you cropped a 8bit png and saved as 24bit?

3 Name: 4n0n4ym0u5 h4xx0r : 2013-09-06 04:25 ID:DP7+Y0kk

Nope, no format change. though the images were all .JPG as I recall. The program I did the editing in was XNview.

4 Name: Kovalski : 2014-08-10 13:12 ID:8GHeQ3Of

It can be happened for some reasons. I saw such thing for once when I edited my icons using special editors from aha-soft.com maybe other I don't remmeber exactly. I cropped a picture a lil bitbut I set the edges of the croppin frame OUTSIDE the edge of the picture. After I cropped programm added this piece to initial picture and it became larger.

>>1 is probably long gone, but anyway.

When you do something to a jpeg image, this is usually how an image editing program would do it:

(loading)

  1. Decompress jpeg file
  2. Convert jpeg macroblocks to bitmap
  3. Do image editing operation

(saving)
4. Convert bitmap to jpeg macroblocks
5. Throw away some amount of detail (configurable)
6. Compress jpeg file
7. Add metadata (like "CREATED BY ADOBE PHOTOSHOP LOLOL", thumbnail, date and time, etc)

How will the failure of net neutrality effect online gaming? (4)

1 Name: Bill of the Gates : 2014-01-27 12:03 ID:1mJ/GH/f

How will the failure of net neutrality effect online gaming? Will I have to pay more to play world of warcraft?

2 Name: 4n0n4ym0u5 h4xx0r : 2014-06-04 19:49 ID:BFx+5FvW

Probably not. If your ISP is so evil as to try to extort money from someone, it will most likely be Blizzard, or the company that makes the game you want to play. And if Blizzard don't comply, your ISP might try to drive away Blizzard's profits by slowing down everyone's connection to their servers. So no, if this repeal comes into force, you probably won't be affected monetarily.

3 Name: Bill of the Gates : 2014-06-09 17:11 ID:eOdvkNAZ

So instead of costing me more, it'll just make me more likely to get ganked then when playing online. It is probably a good thing I don't have Comcast any more, greedy comcastards...

[HELP] Single questions & Help Thread [n00b] (354)

1 Name: CyB3r h4xX0r g33k 2005-09-05 20:53 ID:KxkIsG20

If you have a single (or some more) question regarding any of the tech topics of this board and feel that it wouldn't justify creating an own thread just for that, feel free to post it in here.

If you know the answer to any of the questions in this thread, please help us out here! I am sure it's going to be appreciated.

I am creating this thread since there's ben popping up too many threads lately with single questions asking for help that aren't really set out to create too much interest.

Thank you for your reply.
The output of ifconfig gives me values for "inet addr," "Bcast," and "Mask." So I guess I can assume those values are the current LAN address, the Broadcast and the Netmask? Should the broadcast number look something like 255.255.255.255? I know the mask should look like that, but other guides say that the broadcast should be the last address in your network's range, like, for your example, "192.168.0.255," so the output confuses me a little.

Does iTunes for Windows do anything to your music files at all?

As in, does it have any sort of deal where when you add your giantass folder of music to its library, it renames all the music files to random alphanumeric things like "HH23X9.mp3 and then places them in a folder tree with names much similar to that? Or does it add some sort of code to your files that only allows them to be played back from within iTunes?

For various reasons I will be forced to use iTunes for the management of my music library but I'm almost scared to try this because I hear things like this about iTunes for Windows very frequently.

Can anyone confirm or deny any of this for me?

I only used it briefly, but I think it stores its own metadata without actually touching your files. That would create problems for a lot of people.

There's probably an option to move/rename/tag music, though.

I use Debian wheezy and the official Firefox binaries.

Just go to the Firefox website and hit the download button. It'll give you a .tar.bz2 with firefox/ inside. Extract that somewhere you have read/write access to--I used /opt/firefox/. After that, add that directory to your $PATH (e.g. open up ~/.profile and add something like PATH="/opt/firefox:$PATH"). Firefox's own updater should be able to update the software with no problems. Setting up any sort of desktop or menu shortcut shouldn't be difficult, just set it to run firefox (or the full pathname) and to use the icon in the firefox/icons/ directory.

Admittedly, it's not the best solution, but it works and ensures you get timely updates straight from Mozilla, with all the dependencies included. However, you may run into troubles with update-alternatives and the like, and you might have to set some options in your desktop environment (if you use one). But in lieu of a proper Mozilla Debian repository (maybe there is one, I haven't checked), it's one of the easiest ways to go about it. Maybe someone a little more package-savvy than myself could write a script that automatically fetches the latest binary, packs it into a .deb, and adds the relevant metadata? I don't see why it would be too hard.

How do I define my own keyboard shortcuts in Firefox under Linux? Make whatever keys I want perform whatever action I want and whatnot?

350 Name: 4n0n4ym0u5 h4xx0r : 2012-11-11 19:47 ID:LOUpMS5f

Running Debian 64-bit. Tried to enable multiarch to install Wine 32bit. I was suggested these commands by the "wine64-bin helper package." I ran these commands as root:

# dpkg --add-architecture i386
# apt-get update
# apt-get install wine-bin:i386

When I tried the last command, this was the output:

http://pastebin.com/brSXhAny

The most relevant information, I think, is at the bottom:

dpkg: error: --configure needs a valid package name but 'libuuid1' is not: ambiguous package name 'libuuid1' with more than one installed instance

TRON is just a specification, but there is a tron-conforming open source os-skeleton available. Skeleton means it lacks code for communicating with processor and memory, if I remember correctly. It does have the higher-level interfaces and some drivers ready as well as the real-time time-allocation stuff.

Also, you already have an I(ndustrial)-TRON system if you have a Japanese camera or car.

This is the current project's web site: www.t-engine.org

So, TRON isn't 'non-existent' as some people seem to believe.

http://www.t-engine.org/download/index.php?route=product/product&product_id=123

This is the main source. There is also t-microkernel and some packages I don't really know about. If you want to get a t-kernel running you should know your target system's memory management support and the type of processor. It's possible, but if you can do it you can just walk in to some software company and ask for a job. I haven't found any 'ready-to-go' source packages.

How does one download Wikipedia for offile reading, in Linux? (4)

It is in fact possible to keep and offline mirror of Wikipeda for yourself. But just the text of it obviously. If you tried to download ALL of every Wikipedia article, including sounds images and videos, it would probably be a couple terabytes in size.
Now, I can't for the life of me though figure out how to do it in Linux. I can find page after page of how to do it in Windows, but nothing for Linux. Help please?
