  • Douglas Adams Describes the Invention of the Ebook [Video]

    - by Jason Fitzpatrick
    In 1993, Douglas Adams–of The Hitch Hikers Guide to the Galaxy fame–lent his creative talent and voice to explaining the invention of the Ebook. The audio segment was produced almost 20 years ago by Adams to both promote his own work in digital format and the work of early ebook publisher Voyager Expanded Books. You may notice Adams refers to their product as a PowerBook, a name they kept until they heard Apple would be releasing a laptop with the same name (from then on the product was simply referred to as Expanded Books). The thoroughly modern video accompanying Adams concise and entertaining description of book history is an animation courtesy of U.K. designer Gavin Edwards, which he submitted to a contest hosted by The Literary Platform intended to match a clever animation with Adam’s monologue.

  • Why don't we just fix Javascript?

    - by Jan Meyer
    Javascript sucks because of a few fatalities well pointed out by Douglas Crockford. We talk a lot about it. But the point here is, why we don't fix it? Coffeescript of course does that and a lot more. But the question here is another: if we provide a webservice that can convert one version of Javascript to the next, and so on, we can keep the language up to date. Such a conversion allows old code to run, albeit with an ever-increasing startup delay, as newer browsers convert old code to the new syntax. To avoid that delay, the site only needs to take the output of the code-transform and paste it in! The effort has immediate benefits for those businesses interested in the results. The rest can sleep tight: their code will continue to run. If we provide backward code-transformation also, then elder browsers can also run ANY new code! Migration scripts should be created by those that make changes to a language. Today they don't, which is in itself a fundamental omission! It should be am obvious part of their job to provide them, as their job isn't really done without them. The onus of making it work should be on them. With this system Any site will be able to run in Any browser, but new code will run best on the newest browsers. This way we reap the benefit of an up-to-date and productive development environment, where today we suffer, supposedly because of yesterday. This is a misconception. We are all trapped in committee-thinking, and we drag along things that only worsen our performance over time! We cause an ever increasing complexity that is hard to underestimate. Javascript is easily fixed. The fact is we don't. As an example, I have seen Patrick Michaud tackle the migration problem in PmWiki. It included forward migration scripts. Whenever syntax changes were made, a migration script was added to transform pages to the new syntax. As far as I know, ALL migrations have worked flawlessly. In other words, we don't tackle the migration problem, we just drag it along. We are incompetent! And why is that? Because technically incompetent people feel they must decide for us. Because they are incompetent, fear rules them. They are obnoxiously conservative, and we suffer the consequence of bad leadership. But the competent don't need to play by the same rules. They can (and must) change them. They are the path forward. It is about time to leave the past behind, and pursue the leanest meanest, no, eternal functionality. That would in and of itself revolutionize programming. So, why don't we stop whining and fix programming? Begin with Javascript and change the world. Even if the browser doesn't hook into this system, coders could. So language updaters should take it upon them to provide migration scripts. Once they exist, browsers may take advantage of them.

  • Themes for jQTouch

    - by Leticia Meyer
    I've been using jQTouch to make an iphone-like website. But, I don't want it to look like a native iPhone app (Since people will be using it on other phones), but I don't really like the included JQT theme. Anyone know any other themes? I've searched long and hard, but can't find any. If worst comes to worse, I guess I could always make my own, but I'm not too good at graphics. Just wondering if anybody knows about any others, including those in demos? Thanks in advance! -Leticia Meyer

  • How does timeseal work? [on hold]

    - by Simon Meyer
    I know the the fics (free internet chess server: www.freechess.org/) does use a program called timeseal to measure the time that a user needed to take a move. This timeseal is some time measurement on the client. Measuring on the client is much better and fairer than measuring the time on the server since you don't lose time just by having a bad connection. But since fics has a lot of interfaces to play on - what prevents rogue interfaces to say that they always only used 0.1 seconds for any move? Does anyone know how this is handled? Just a sidenote: i don't want to build a rogue interface, but i'm trying to build something similar that is measuing client side time but should not be easy to cheat on.

  • Where should you put constants and why?

    - by Tim Meyer
    In our mostly large applications, we usually have a only few locations for constants: One class for GUI and internal contstants (Tab Page titles, Group Box titles, calculation factors, enumerations) One class for database tables and columns (this part is generated code) plus readable names for them (manually assigned) One class for application messages (logging, message boxes etc) The constants are usually separated into different structs in those classes. In our C++ applications, the constants are only defined in the .h file and the values are assigned in the .cpp file. One of the advantages is that all strings etc are in one central place and everybody knows where to find them when something must be changed. This is especially something project managers seem to like as people come and go and this way everybody can change such trivial things without having to dig into the application's structure. Also, you can easily change the title of similar Group Boxes / Tab Pages etc at once. Another aspect is that you can just print that class and give it to a non-programmer who can check if the captions are intuitive, and if messages to the user are too detailed or too confusing etc. However, I see certain disadvantages: Every single class is tightly coupled to the constants classes Adding/Removing/Renaming/Moving a constant requires recompilation of at least 90% of the application (Note: Changing the value doesn't, at least for C++). In one of our C++ projects with 1500 classes, this means around 7 minutes of compilation time (using precompiled headers; without them it's around 50 minutes) plus around 10 minutes of linking against certain static libraries. Building a speed optimized release through the Visual Studio Compiler takes up to 3 hours. I don't know if the huge amount of class relations is the source but it might as well be. You get driven into temporarily hard-coding strings straight into code because you want to test something very quickly and don't want to wait 15 minutes just for that test (and probably every subsequent one). Everybody knows what happens to the "I will fix that later"-thoughts. Reusing a class in another project isn't always that easy (mainly due to other tight couplings, but the constants handling doesn't make it easier.) Where would you store constants like that? Also what arguments would you bring in order to convince your project manager that there are better concepts which also comply with the advantages listed above? Feel free to give a C++-specific or independent answer. PS: I know this question is kind of subjective but I honestly don't know of any better place than this site for this kind of question. Update on this project I have news on the compile time thing: Following Caleb's and gbjbaanb's posts, I split my constants file into several other files when I had time. I also eventually split my project into several libraries which was now possible much easier. Compiling this in release mode showed that the auto-generated file which contains the database definitions (table, column names and more - more than 8000 symbols) and builds up certain hashes caused the huge compile times in release mode. Deactivating MSVC's optimizer for the library which contains the DB constants now allowed us to reduce the total compile time of your Project (several applications) in release mode from up to 8 hours to less than one hour! We have yet to find out why MSVC has such a hard time optimizing these files, but for now this change relieves a lot of pressure as we no longer have to rely on nightly builds only. That fact - and other benefits, such as less tight coupling, better reuseability etc - also showed that spending time splitting up the "constants" wasn't such a bad idea after all ;-)

  • How do I serve dynamic WebDAV directory listings using Apache

    - by Jack Douglas
    I can use mod_rewrite to redirect /dynamic.php/xyz.php to /dynamic.php and then server different content for xyz.php using $_SERVER - where xyz.php is any arbitrary filename requested by a client. No problem so far. When a client connects to my WebDAV server they can list the contents of a directory, eg / or /dynamic.php/ - how do I intercept this request so I can dynamically generate a list of available files for the client (which requests this list using PROPFIND)?

  • Ubuntu 12.04 + Raid0 + Windows 7 not loading

    - by Douglas
    please someone help me.... (Sorry for my english) Hi, I have a Pc with 2 Hd (1Tb each) on Raid0. I had a Windows 7 64bits working for several months. When I installed the Windows I let a 100Gb partition empty to install Ubuntu someday. I was using Linux on a Virtualbox, but this week I tried to install Ubuntu 12.04 in this 100Gb partition. I used the Ubuntu alternate cd, because the 'normal' cd was giving me trouble with the Raid0. The grub installation always reported a error. After a lot of work I found that I nedded to install grub on partition /dev/mapper/isw_chjbfeec_DougRaid1 (see Bootinfo below). The Windows installation created a 100Mb boot partition, so I needed to install grub in this partition. Now I have the Ubuntu working 100% ok. The problem is, the Windows is not booting! The windows option is present on the grub menu, but when I choose the windows option there is a black screen and after that the grub is reloaded.

  • Does the latest version of Ubuntu (12.04) support Unity 3D?

    - by Douglas Combs
    I just installed the latest version of Ubuntu (12.04) 64bit. I am using a Radeon HD 7750 vid card. I think I have the Catalyst driver installed correctly. But when I go to system and look at the details, it shows that my graphics is VESA:01. Does this mean I it, I didn't correctly install my driver? System Specs: MB: ASUS P7P55-M CPU: Intel i5 Quad Core MEM: 4GB DD3 VC: HIS Radeon HD 7750 (1GB DDR5) Thanks for help.

  • Multi-Threaded Pipelined Game Engine Data Synchronization Questions

    - by Douglas
    Let's say I'm setting up a worker pool based game engine with pipelining. Let's say I have 4 stages in my pipeline as such: Stage 1: Physics Stage 2: AI/Input Stage 3: Game Logic Stage 4: Rendering Now let's say that the physics detects a collision between a bullet and a character in stage 1. Two frames later the game logic may choose to remove that bullet from the simulation, however none of the other copies of the data for the other pipeline stages will get this information. How is this sort of thing and other things like it get handled? Do you generally make changes like this to every pipeline stage's data at the end of a frame?

  • Good book for a software developer doing part-time (Linux) system administration work

    - by Tony Meyer
    In many smaller organisations, developers often end up doing some system administration work (for obvious reasons). A lot of the time, they have great developer skills, but few system administration skills (perhaps all self-taught), and so have to learn as they go, which is fairly inefficient. Are there canonical (or simply great) books that would help in this situation? More advanced than just using a shell (presumably a developer can do that), but not aimed at someone that hopes to spend many years doing this work. Ideally, something fairly generic (although specific to a distribution would be OK), covering databases, networking, general maintenance, etc, not just one specific task. For the most part, I'm interested in shell-based work (i.e. no GUI installed), although if there's something outstanding I'm missing, please point it out. (As an analogy, replace "system administration" with C, and I'd want K&R, with C++ and I'd want Meyers' "Effective C++").

  • How to chroot Apache on CentOS?

    - by Jonathan Meyer
    I have been advised by a sysadmin, to run Apache in a chroot jail, in order to prevent that an attacker could take control of server. So my question is: What is the best method to chroot Apache/2.2.3 in RHEL/CentOS 5?, i only use the default modules that comes with Apache like mod_php and also mod_security. I heard of mod_security SecChrootDir but i don't know if it would be suitable for my config, it says that it's recommended only for static file serving in the documentation. Thank you!

  • Excel: conditionally format a cell using the format of another, content-matching cell

    - by Eric A. Meyer
    I have an Excel spreadsheet where I’d like to be able to create a “key” of formatted cells with unique values, and then in another sheet format cells using the key formatting. So for example, my key is as follows, with one value per cell and the visual formatting indicated in parentheses: A (red background) B (green background) C (blue background) So that’s on one sheet (or in a remote corner of the current sheet—whichever is better). Then, in an area that I mark for conditional formatting, I can type one of those three letters and have the cell where I typed it visually formatted according to the key. So if I type a “B” into one of the conditionally formatted cells, it gets a green background. (Note that I’m using backgrounds here solely for ease of explanation: ideally I want to have all visual formatting copied over, whether it’s foreground color, background color, font weight, borders, or whatever. But I’ll take what I can get, obviously.) And—just to make it extra-tricky—if I change the formatting in the key, that change should be reflected in cells that reference the key. Thus, if I change the “B” formatting in the key from a green background to a purple background, any “B” in the main sheet should switch to the new color. Similarly, it should be possible to add or remove values from the key and have those changes applied to the main data set. I’m okay with the formatting-update-on-key-change being triggered by clicking a button or something. I suspect that if any of this is possible it will require VBA, but I’ve never used it so I’ve no idea where to start if that’s the case. I’m hoping it’s possible without VBA. I know it’s possible to just use multiple conditional formats, but my use case here is that I’m trying to create the above-described capability for someone who isn’t conversant with conditional formatting. I’d like to let them be able to define a key, update it if necessary, and keep on truckin’ without me having to rewrite the spreadsheet’s formatting rules for them. --- UPDATE --- So I think I was a bit unclear about my original request. Let me try again with an image. The image shows the “key” on the left, where values and styles are defined using keyboard and mouse input. On the right, you see the data that should be formatted to match the key. Thus if I type a “C” into a cell in the Data area, it should be blue-backed. Furthermore, if I change the formatting of “C” in the Key to have a purple background, all the “C” cells should switch from blue to purple. For further craziness, if I add more to the Key (say, “D” with a yellow background) then any “D” cells will be styled to match; if I remove a Key entry, then matching values in the Data area should revert to default styling. So. Is that more clear? Is it possible, in whole or in part? I don’t have to use conditional formatting for this; in fact, at this point I suspect I probably shouldn’t. But I’m open to any approach!

  • Is it possible to disable the retry mechanism in Exim

    - by Tony Meyer
    I have a very simple Exim configuration that's just forwarding all mail to a set of destination addresses. When immediate delivery to an address fails, the message is added to the queue (and then processed by the retry rules). I want to change this so that if immediately delivery fails, the message is :blackhole:d. (It's ok if a bounce is generated instead, as I'll just redirect the bounce to the :blackhole:). This needs to occur for temporary failures (i.e. 4xx) as well as permanent (i.e. 5xx) ones. I understand that this means that if delivery can't be done immediately the message will be permanently and irretrievably lost. In this particular context, that isn't a problem. Reading over this, it sounds suspiciously like "how can I improve my spamming Exim server". That really isn't what this is for, and if you can figure out a way I can prove that, I'm happy to do so!
