  • Anyone have any opinions about Chilkatsoft? [closed]

    - by Joe Enos
    I'm considering purchasing the Chilkatsoft bundle, which includes a bunch of libraries on lots of technologies. Specifically, I care about .NET compression, encryption, FTP, and mail libraries, but I'm interested in looking at the rest of their stuff as well. Does anyone have any experience using these libraries, or opinions on the company or product in general? The price is right, and the content seems good, so I just want to make sure I do my homework before purchasing. Thanks

  • How to implement a multi-part snake with smooth movement? [closed]

    - by Jamie
    Sorry that i couldnt answer on my previous post but it got closed. I couldnt answer because i had to prepair for my finals. As there were problems with understanding of what im trying to achieve, im going to describe a little bit more in depth. Im creating a game in which you steer a snake. I assume everybody knows how that works. But in my case the snake isnt just propagating in an array element by element. Imagine a 2Dgrid on which the snake moves. Its 10x10 tiles. Lets say one tile is 4x4 meters. The snakes head spawns in the middle of the (3,2) tile (beginning with (0,0)), so its position is (4*3+2,4*2+2)(the 2's are so that the snake is in the middle of the 4x4 tile). And heres where the fun begins. when the snake moves, it doesnt jump to next tile. Instead it moves a fraction of the way there. So lets say the snake is heading to tile (4,2). After it moved once, its position is (4*3+2+0.1,4*2+2), where 0.1 is the fraction of the way it moved. This is done to achieve smooth movement. So now im adding the rest of the body. The rest is supposed to move along the exact same path as the head did. I implemented it so that each part of the body has its own position and direction. Then i apply this algorithm: 1.Move each part in its direction. 2.If a part is in the middle of the tile(which implies all of them are), change each parts direction to the direction of the part proceeding it. As i said before i could make this work, but i cant stop thinking that im overlooking a much easier and cleaner solution. So this is my question. Is there any easier/better/faster way to do this?

  • Why is the Amazon and Ubuntu One Music webapp part of common? Can it be removed without removing all others?

    - by DoDoGo
    I've just noticed that those two, which I have completely no use of, are part of the common package. This means I cannot remove them without removing everything. But I like all the other webapps, GMail, Docs and so on. I just don't want Amazon popping up in my launcher when I go there once a blue moon and not leaving until I turn Firefox off. Is there any way I can remove it without removing the rest?

  • admin-over-clients application

    - by azzido
    I have the same web application running on several different servers. Now I want a central place to administer everything in one web interface. What is the best way to do this? Should I provide a REST interface on every web application and let the admin application make all the calls? This seems like a common problem that's already been solved by smarter people than me. UPDATE: I want to change the application data per web application + see the results per web application

  • What are the names of default indicators in Ubuntu 11.10?

    - by sup
    How are they called? It is useful for configuring them via dconf, reporting bugs and so on but hard to find out. I remember there was similar wuestion for 11:04 but cannot find it. These are the indicators on my system: There are ten, the last one on the left is Tomboy, the rest is more or less default (the second from the left is displayed only if more than one keybord layout is used). What are their names?

  • Should You Bother to Create Meta Tags For Your Website?

    Some people will tell you that since Google no longer uses meta tags as a factor in your search engine placement that it is no longer necessary to include them in your website SEO. It is true that the Big G is top dog in the search engine game, and it is true that having meta tags will not do anything for your SERP with them, but what about the rest of the search engines?

  • swapping or trashing with vast amounts of unmapped pagecache

    - by Marco
    I'm using kubuntu jaunty (i386 32bit), kernel 2.6.28-13-generic. I've 4Gb of RAM, of which only 3317Mb are seen by the system (I guess because of the 32bit system). I'm seeing that the pagecache utilization is continually growing, up to the point that the system is unusable (after a few days). This happens also when I don't do anything (all user applications closed and the bare minimum of services enabled). If enabled, the system starts to use swap space (using it all in the end). Even if swap is disabled, disk activity becomes continuous, with the system unresponsive. For example, right now the system is working (albeit a tad slow), with only firefox and wing ide running, and I have 2Gb cached with only 45Mb mapped: $ free total used free shared buffers cached Mem: 3346388 3247328 99060 0 8416 2117980 -/+ buffers/cache: 1120932 2225456 Swap: 2144668 519448 1625220 $ cat /proc/meminfo MemTotal: 3346388 kB MemFree: 97128 kB Buffers: 7872 kB Cached: 2120224 kB SwapCached: 413860 kB Active: 2304596 kB Inactive: 865984 kB Active(anon): 2279168 kB Inactive(anon): 830236 kB Active(file): 25428 kB Inactive(file): 35748 kB Unevictable: 32 kB Mlocked: 32 kB HighTotal: 2492940 kB HighFree: 5456 kB LowTotal: 853448 kB LowFree: 91672 kB SwapTotal: 2144668 kB SwapFree: 1625244 kB Dirty: 84 kB Writeback: 0 kB AnonPages: 629304 kB Mapped: 45768 kB Slab: 45600 kB SReclaimable: 21756 kB SUnreclaim: 23844 kB PageTables: 4468 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 3817860 kB Committed_AS: 3735020 kB VmallocTotal: 122880 kB VmallocUsed: 9352 kB VmallocChunk: 66600 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 888832 kB If I try to drop the caches, little happes: # sync ; echo 3 > /proc/sys/vm/drop_caches ; free total used free shared buffers cached Mem: 3346388 3220580 125808 0 3020 2100600 -/+ buffers/cache: 1116960 2229428 Swap: 2144668 519356 1625312 Right now I've vm.swappiness = 5, but I've tried also with 0 and 1 (without noticeable differences).
