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.

I've got a problem with my IP address. My modem is connected to my router and my router is connected to the other computers including my own and they all share the same IP address. How would I assign different IPs to the computers (2).

I'm on a static IP plan with my ISP as that's all they provide.

302 Name: 4n0n4ym0u5 h4xx0r : 2008-11-01 12:42 ID:3nBlYWwF

If you want unique IPs for each box, you need to to purchase a subnet block (usually a /29) from your ISP then reconfigure your router. Having an ISP that doesn't suck and some networking knowledge is a start.

Total noob/dumb question here:

I have Firefox clear my cache and cookies automatically every time I close Firefox. I also use CCleaner; which I have set to clean everything 7 times over. My question is, since I have Firefox clearing my cache every time I close it, does CCleaner still clean the cache and cookies from FF too? Or should I turn the function off in FF so CCleaner can clean everything 7 times.

Hope all of that made sense....

I have a tv hardware question here(It would really help if anyone who answers was a Chicagoan like me), anyway I got a new HDTV along with a antenna for local HDTV and digital channels. Anyway about a month ago one of the station finally went HD after moving in a new building(for the Chicago users it's channel 2). But for some reason my tv can't get the HD/digital signal. Is something wrong or somthing that I could do to fix it?

Does anyone know of a good open source BT tracker (not software, an actual tracker) that's reliable? I'd like to create a few torrents for an open source project, and would rather not track them on TPB.

Thank you, that is exactly what I was looking for.

If Firefox has already cleaned the cache, CCleaner will not be able to do anything. That is, unless it's very clever and installs a filesystem filter driver or something -- based on the product documentation it's not doing anything of the sort (lol, VB 6).

If you're using CCleaner for the shredding (secure delete) feature then you most likely want to use CCleaner alone to clean your FF cache. The downside being that the cache is not guaranteed to be cleaned immediately after you exit FF.

let me see if i can explain this right...

i've got 2 160 gb hdds in my computer. i recently backed up my info from my old setup on one hdd, and i copied all of the info from that hdd to the hdd i'm using now. my question is, is there a way to back up the new info that i've got on my main hd to the other one? i dont want to backup everything, just the stuff i've downloaded recently on my main hdd (e.g. music, pictures, ect...)

hope all that made sense...

There is software that will do this for you. I use Rsync on my unix boxen, I believe there is a windows port too.

311 Name: 4n0n4ym0u5 h4xx0r : 2008-12-04 21:38 ID:j3A0Oyto

rsync is awesome. I'm 95% sure it's what OS X's Time Machine (think Windows System Restore/Shadow Volume Service) uses. Oldish Win32 port. Cygwin+rsync easy to use package.

I've two questions:

+I use a standard PC 104-key USB keyboard plugged with a MacBook Pro running OS X. I would like to use the home, end, pgup, pgdown, etc buttons with it, but they don't work. If possible, I'd rather not have to hold some retarded quintuple-bucky keycombo to achieve the Shift+Home or Ctrl+ArrowKey type behavior you see in oh, say, every other fucking text editing GUI ever made that's worth it's salt. Even just a pointer to the right configuration panel would be greatly appreciated.

+The built in OS X Terminal app does weird things with very dark greys (irssi hashmarks surrounding nicknames) even if it's at 100% bg opacity. Putty in Windows displays them properly -- I guess it could be the monitor profile settings in OS X. Also, for some reason IME doesn't work with it (even though it does support unicode up to at least UTF-8 if you copy and paste). It just sucks in general IMO. Does anyone know if iTerm (or any other alternative OS X terminal app) will fix these issues, preferably without sucking in general?

TIA. Also, please feel free to keep the "lol you're a macfag" comments to yourselves. I am aware that some of you may hold this opinion, and may even be correct, but I do not give a flying fuck.

312 Name: >>311 : 2008-12-06 02:12 ID:Heaven

iTerm fixed all of the problems in >>311 but one. I still can't use the home and end keys (or stuff like Ctrl+Arrow, Ctrl+Shift+Arrow) on my PC-104 properly in any os x app besides iTerm >_<.

I think what I really need is a windows/linux to os x transition cheat-sheet. Anybody know of a good one?

This just started happening the other day...

Every time I play music on my computer, (it doesn't matter what media player I use) and click on something else on my computer (pictures, or actually click out of my media player) I always here what sounds small skips in the song. The more I click on something, the worse it gets. It doesn't happen when I'm on the Net; I can click all over the place and nothing happens. I also just reformatted a few weeks back, so nothing is really taking up system resources. I've scanned for spyware, and viruses, but nothing comes up. Anyone have any ideas?

314 Name: 4n0n4ym0u5 h4xx0r : 2008-12-07 21:53 ID:8mdpAe7d

I keep gettin popups even though I'm not on websites that usually bring up popups.
I also get popups when I'm not using the internet(it just opens firefox by itself and starts poppin up ads from interplus click or something.)

I tried Spybot, Adaware, RegistryFix,AVG Antivirus, and everything. Does anyone know what I can do to get rid of it? Is it spyware? Or a Virus?

315 Name: 4n0n4ym0u5 h4xx0r : 2008-12-18 01:22 ID:VPi8Ln69

wondering if someone could help me here...every once in a while, this error message pops up in windows. it usually happens when i click on a song. i know when its about to happen, cause the system lags for a bit, finally plays the song, then the message pops up.

if i push ctrl+alt+del, and go into the task manager, it says that the "my music" folder isn't responding. anyway, this has been happening for a long time now (pretty much since I got my computer a while back) and it still happens even after I re-format and even put XP Pro on my machine.

here's a picture of the error message if it helps: http://tinyurl.com/3t8pq4

strange question here...

when i watch a video on my web browser the sound is very muddled and distorted. but when i open a new tab and do something else, the sound gets better. and as soon as i switch back, it gets bad again. also, when i scroll a webpage down, it makes the same sound. any thoughts? thanks!

319 Name: 4n0n4ym0u5 h4xx0r : 2009-01-02 11:00 ID:WXuhHeZs

Sounds like your browser's hijacked. Unfortunately I'm not sure what to do about that. I'm actually on a hijacked browser myself at a friends house right now...

Not really sure what the issue is, but about 4 images I've downloaded through torrents recently have been corrupted. I've never had this issue before, and it all seems to have started after this install of windows... I'm even downloading torrents that I'd already downloaded before and finding the images corrupted, or something. Anyone know what's up?

Ive found TVersity to work well for all of my streaming needs. After setting it up and navigating to your media server, click the RSS button at the top of the screen. this will save it as a feed with which you can access via the psp. As for pictures, navigate to the server and click a pic to d/l it. I was doing this earlier before coming here to post. psp sucks unless you are tech savvy.

quick question, im a noob to the computer world, well the hardware aspect of it at least, so does anybody know a good website with really understandable wording that could tell me what every piece does prosseser, graphics card etc. does and whats the best one on the market is? Ive read a lot of magazines on the topic but they were really confusing and i could only get the base info out of them.


327 Name: 4n0n4ym0u5 h4xx0r : 2009-03-24 22:12 ID:cbNmptVE


Processor does math.
Graphics card does pictures.
There is no 'best one on the market' for computer parts just like there is no 'best one on the market' for automobiles.

328 Name: 4c0st0s5!Ep8pui8Vw2 : 2009-03-28 18:36 ID:zZ55bNG3


>>327 did a pretty good job of summarizing it.
There are alot of standards, types and derivatives of most computer parts (SATA vs. ATA; DIMM vs. 184pinDDR2SDRAM vs. 240pin DDR2SDRAM; ect). It is also quite unrealistic to expect to get 'the best one on the market' unless you have a shitload of discretionary money, and assuming you did, it would be best to pay an IT guy to do it for you. If not, buy or P2P a "Computer Hardware for Dummys" type of book.

What exactly do you want to do? If you want to build a computer, it's best to buy a junker in the classifieds in your local paper, and upgrade it, plus it's alot cheaper.

Okay, so I'm trying to fix this guy's vista laptop. First off, one day he just can't seem to boot it up. eventually, he gets it to the login screen, but it won't go pas it. I get it from there and notice the same thing. I run vista's own system checking doohickeys - recovers from some severe filesystem errors. Basically, now, the laptop SEEMS to be fixed. It loads up really fast, no glitches anywhere, BUT... the password he used to use doesn't work anymore... no password works.

there's no other users. I can't just over-install vista to get a new password because you can't do that unless you've already logged in. Desperate, I downloaded OPHCrack or whatever, to crack what the password is... error.

Is he fucked? The only thing I can think of is to download a live-dvd linux, and try and save his files that way before he wipes it. either that, or just send it back to Dell. thoughts?

331 Name: 4n0n4ym0u5 h4xx0r : 2009-04-02 03:52 ID:UeTLkCWR


NM, turns out the guy had changed his pass without telling anyone. yeesh

332 Name: 4n0n4ym0u5 h4xx0r : 2009-04-24 15:09 ID:gz1O9pQ1

Is there a way to easily change the default names assigned to drive letters in vista?

eg. i used to have a USB 4-in-1 card reader which I always had plugged in, and all its slots showed up as "removable disk" so i renamed them to "SD Reader", "CF Reader" etc for ease of identification.

i thought that would only apply to this specific hardware but apparently not - i now have an internal card reader installed, so having removed the external one, i now find that any usb flash drive i plug in which is assigned one of the letters formerly occupied by the card reader will be called "SD Reader" or similar if the drive doesnt have its own name. and renaming would then only change the name of the drive itself, not the drive letter.

its now slightly worse in that i have installed a dvd drive which windows refuses to let me rename at all, but it's showing up as "DVD-RW Drive (G:) SD Reader". so uh yeah. any way to change these back to the default without having to remove the dvd drive and replacing the card reader?

333 Name: 4n0n4ym0u5 h4xx0r : 2009-04-24 15:14 ID:gz1O9pQ1

actually nevermind, worked it out. i just searched the registry for one of the changed names, deleted the "DefaultLabel" key under the respective drive letters. works. yay.

Hey guys, I have a really annoying problem on my home network. When ever my little brother is playing a MMO and I'm watching videos on YouTube or something similar it lags him really bad. He uses windows xp and I have a MacBook running OS X 10.5. When ever him and our mom are online and shes doing something similar theres no problem. When him and a friend play this game there are no problems. They've had as many as three people on our network playing the game at the same time. It only lags when I'm on. I've tried turning EVERYTHING off. He only lags when I'M downloading or streaming a video or something. What should I do? Is OS X just a bandwidth hog? Honestly I think hes lying but just in case I'm wrong does anyone know what might be going on???

My question is how to get my C: directory to show up as a subfolder menu within the my Quick Launch toolbar in Vista (yeah, yeah, I know...) after clicking the ">>" icon. I've tried several things, but each attempt usually ended up as a link to the directory as opposed to a menu and would just open in a different window. I've tried googling some potential solutions, but they all say the same thing and none of them work. I know this is possible (somehow), as I've done it prior to reinstalling (again, somehow); I just don't remember what I did, or if I did anything special to begin with. I thought it might be some kind of hidden option that I haven't tinkered with yet. Any suggestions?

Does anyone know how to set up a vanilla LaTeX distribution to properly typeset Japanese documents made in PLatex2e? Or would it be better to just switch to PLatex2e entirely for Japanese documents? In that case, is there a decent English tutorial for using PLatex2e?

340 Name: 4n0n4ym0u5 h4xx0r : 2012-06-18 18:36 ID:7tXJRt/c

If you're on Windows, you could try MiKTeX. It downloads packages when you need them.

341 Name: 4n0n4ym0u5 h4xx0r : 2012-06-20 22:36 ID:wv/+lgkA

I'm already using MiKTeX. The problem is that the packages written for PLatex2e seem to be either partially incompatible with MiKTeX's LaTeX implementation, or impossible to find the right version of. I am still quite inexperienced with LaTeX, and for now I'd be happy even just to know what kind of packages and fonts are best to use for setting Japanese text. Later on I'd like e.g. support for vertical writing as well --- not sure if that's easily done in LaTeX.

If I'm setting up a home server with Debian, and I need to have a static IP address, what values do I plug in to my /etc/network/interfaces file and how do I find them? For example, what values should I use for address, netmask, network, gateway and broadcast?
Are there any guides or manuals that explain this? I haven't found one. They all explain how to format them, but I have no clue what values to use or how to find them.

343 Name: 4n0n4ym0u5 h4xx0r : 2012-08-15 12:15 ID:ByYvKJGI

It's pretty simple after you've done it a couple of times, just like building the Linux kernel as a beginner.

For starters, remember that the IP you'd configure in /etc/network/interfaces is your LAN IP, i.e., not your WAN IP.

Assuming your router is, we could use as our LAN IP. For this, we'd use "address". The "ghetto" method of getting the other values would be to connect via DHCP, run ifconfig, writing down the values, and transferring them into the interfaces file.

Simply add them in, change the address (if necessary), and, voila.

A quick example:

allow-hotplug eth0
iface eth0 inet static
# The other values go here...

Sorry if this guide is shit, not able to access a *nix system right now.

344 Name: 4n0n4ym0u5 h4xx0r : 2012-08-15 20:40 ID:pWCPQU8g

Is there a PPA or repo that always contains the absolute latest version of stable, non-beta, Firefox for any general Debian/.deb based distros? Ubuntu, Crunchbang, Trisquel, that sort?

I'm tired of any of my systems getting left behind with older versions of Firefox because I don't feel that I should have to upgrade the whole OS to get one program.

I've only been able to find a PPA for Firefox Beta: https://launchpad.net/~mozillateam/+archive/firefox-next
And even when I added that to my older Ubuntu system it would still return that message the the currently installed version of Firefox is the latest one. Which it is not since I'm still on version 11 here.

Help, please?

345 Name: 4n0n4ym0u5 h4xx0r : 2012-08-16 03:41 ID:sYCeqEuy

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 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, "," 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?

347 Name: 4n0n4ym0u5 h4xx0r : 2012-08-28 15:17 ID:HH6HeEdn

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.

348 Name: 4n0n4ym0u5 h4xx0r : 2012-08-28 15:38 ID:HH6HeEdn

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.

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:


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


E: Sub-process /usr/bin/dpkg returned an error code (2)

The bigger problem is this: the same thing happens when I try to install anything from my package manager. Am I going to have to reinstall?
It's not that huge of a deal if I do, but it will be kind of a bitch. I'll keep looking for solutions and post if I ever get dpkg working again.

351 Name: 4n0n4ym0u5 h4xx0r : 2012-11-11 22:32 ID:LOUpMS5f

Same idiot again. I'm going to go ahead and just backup and reinstall, but if anyone has had this happen before and got it fixed, you can post it. I imagine I'm not the only one, even if it seems like it from the google results I got.

I recently bought a Gateway DX4375-UR22. It came with a 1 terabyte hard drive. I turned it on, and it booted up using Ubuntu. Me being me, I stupidly decided to take it apart. I put it back together, and now there is a problem with the hard drive. Everything else works fine, except for the hard drive. The drive is a Seagate Barracuda 1000 Gigabyte. I decided to try it in another computer, but the other one does not recognize it as a drive. I tried putting a hard drive from another computer into the Gateway to see if it would boot, but no luck. The seagate drive spins, but it is not transferring data or being recognized. Can I save the drive? How can I boot up the computer?

You didn't take the fucking drive itself apart, did you? If so it's fucked, buy a new one.
If I'm reading you wrong, then I guess the chances are you didn't plug it in properly. It's getting power fine, but are you sure there's any actual data connection?

like perhaps how polygons and vector points causes the objects to behave

Hm. First, this is usually done by existing engines. There are 2d physics engines and 3d physics engines, search for them. In simple cases you don't really need for them though.

Try watching unity tutorials, they explained how models often have a different simplified model specifically for physics. Something that looks like a chair may have a much more low polygon collision box than the model you actually look at.

In 2d games, hitboxes are often a bunch of squares, but they can be a bunch of circles, or even repeat the shape of what you see pixel to pixel.

Wow this place is fucking dead.

Existing videocards only work with poligons. At least used to, maybe some insane people made videocards specifically for voxels or something.

>how to calculate the RAM required to run a software from its codes and during programming

1) Run program
2) See how much memory it eats in resource manager or something

Fucking normalfags. We could be leaps and bounds over technological advances, but normalfags are satisfied with incompetent buggy cheaply made shit that falls apart in less than a year

If you know where things get allocated and deallocated, and know the size of them in your language you can probably come up with some values for a given piece of code by just reading through it and keeping track of what's in memory at any given time, if it's not too complicated as to make that unreasonable (you could likely have a static analyzer do that for you in many cases as well, given it's mostly mechanical work). Higher level languages tend to make that harder, but it often isn't impossible.

365 Name: Anonymous Techie : 2021-12-22 21:57 ID:Heaven

What technologies and languages are you guys interested in? There are probably like 3 posters here in total, so I'm curious what everyone has to offer.

I'm interested in gamedev, and I'm most comfortable with python, though I know a bit of everything, C#, Java, javascript, C++, C, x86 and x64 assembly. I'm writing in C++ now, but use about 2% of C++ features, and avoid standard C++ library, using pure winapi instead. Every time memory allocation is involved my brain pretty much freezes in terror, because I don't use vectors or lists, I don't use GlobalAlloc/GlobalFree, I use VirtualAlloc + a probably still buggy List<something> class I wrote + a stack memory allocator that can't free or reuse memory (can only go back to the previous point, by storing somewhere and later restoring usedThisMuchBytes variable).

All modern GPUs are programmable, so there's nothing stopping you from implementing ellipsoid rendering as a fragment shader. This is virtually guaranteed to be slower than the polygon-based rendering that is implemented directly in the GPU hardware though. At least as far as I'm aware, anyone here have OpenGL experience to comment on this?

can you get support studying cloud computing? im very discouraged after failing the first cert test which only have like 10 questions... im not sure i get the whole thing..

i really wanna jump about the whole subject and get a well paying career in it....

How did games like powerdrift defines the tracks back then?
curious how slopes, tilt and elevation was defined even without 3d. also the small tiny lumps gets different treatment too

372 Name: Anonymous Techie : 2022-03-26 14:36 ID:Heaven

You're a fan of asking extremely complicated questions, huh.

Most likely a 2d array. Each element in that array is something like
struct map_element {
int type;
int height;
int rotation;

373 Name: Anonymous Techie : 2022-03-27 00:54 ID:T0QDN3AF

>>372 >complicated
that didnt took you a whole page.
is this proven though? what is a rotation?

374 Name: Anonymous Techie : 2022-03-27 04:40 ID:Heaven

At what angle the fragment of a map is placed. This doesn't seem that important for decorative elements in background like trees, they never rotate, but chunks of map do. I don't know if you can even leave track in that game, so I don't know if you can collide with a tree.

It is also possible that the racing track is stored like a bunch of vectors, array of vectors, "this goes stright and up" "this goes a bit left", "this goes left a lot".

Knowing how it was made back then wouldn't help you much with making games now, technologies are very different.

375 Name: Anonymous Techie : 2022-03-27 11:02 ID:T0QDN3AF

>>374 hmmm. well you can leave the track and falls so theres a "limit"
of the track defined by the map i suppose.

>bunch of vectors

very interesting, can you give example? how can the tracks be merely vectors?

>different technology

indeed. these days its trivial to build tracks in 3d space, i suppose im just curious.

376 Name: Anonymous Techie : 2022-03-27 11:51 ID:Heaven

I mean it could be stored like "next chunk of the road is straight ahead", "next chunk of road is 10 degrees to the left", "next chunk of road is 10 degrees to the right and up". Doubt it works like that, probably just uses a 2d array, 2d array will waste more memory but will probably work faster. It is a guesswork.

struct road_direction {
int vertical_rotation;
int horizontal_rotation;

377 Name: Anonymous Techie : 2022-03-28 07:25 ID:Ao1ird7G

>>376 thres also sagital rotation, as in roads being tilted. so i guess then the array will contain a stack of 2d maps?

378 Name: Anonymous Techie : 2022-03-28 07:48 ID:Ao1ird7G

>>376 also that s just the graphic right? collission/physics not incuded i guess?

379 Name: Anonymous Techie : 2022-03-28 09:16 ID:anu4ByE6

How was physics programmed in Games like radmobile, powerdrift? like how the cars goes up an down and stick to the streets and no "jumps", orient towards tilted sprites... some voxel map? or splines? how do you write splines in 2d engine?

Please explain how ramps are programmed here https://www.lexaloffle.com/bbs/?pid=72871

381 Name: Anonymous Techie : 2022-03-28 16:36 ID:T0QDN3AF

looking for the books to help code games like radmobile, powerdrift, virtuoso in 3do, assortments of things from dealing with camera clipping, ramps that goes around and the physics/collission of the roads that goes tilted or even upside down

where can u find em?

383 Name: Anonymous Techie : 2022-04-21 11:48 ID:Heaven

1) google "cloud engineering courses"
2) pay for those
3) be disappointed that you didn't pay me instead

Does anyone have a recommendation for a technology to build a (relatively) simple game/app that runs in browsers these days?

I would like something a bit more intended for working with graphics/a main loop than JS

Something like Flash or Unity, but hopefully lighter weight.

Godot is capable of creating webbrowser games. You might want to look into webassembly.

FIXING the ENTIRE SM64 Source Code (INSANE N64 performance)
by: Kaze Emanuar

He made Super Mario 64 run at 3 times higher fps even on original hardware. He did it by making sure cpu unit and graphical unit fight for memory less, and adding memory alignment and such. Because of that, the game now requires an expansion pack, increasing the memory requirements from original 4 MB to 8 MB. Plus a lot of other work.

Pity, why they fuck with hardware that isn't even produced anywhere anymore.

388 Name: Anonymous Techie : 2022-06-06 07:17 ID:Heaven

team fortress 2 classic source code. An outdated version, but maybe worth taking a peak at.

I wonder if having no motivation to write programs is a good or a bad thing. It is a waste of time anyway, if you aren't getting paid for it.

It's for the knowledge and the challenge itself. The fame is only a useful side effect.

391 Name: Anonymous Techie : 2022-06-17 07:34 ID:Heaven

In windows 7 I can customize windows colors pretty extensively, but I can't find how to do the same in windows 10. Is it possible to change those? Windows 10 color customization is very very limited, but I suspect that it's still possible to change those old values through registry changes or some side program.
