  • Possible for one developer to work on a site thats on another developer's server?

    - by cire4
    Sorry for the confusing title. Let me explain: I am currently trying to get a site developed. My current developer has taken the site about as far as I think they are capable of and I am planning on hiring another developer to put the finishing touches on it, debug it and upgrade some of the more technical details. The site is hosted on my current developer's server. They are scheduled to work on it until mid-April, at which point they will transfer the site to my server. I would like the new developer to get started on the upgrades to the site as soon as possible. So my question is this: Is it possible for the new developer to start working on upgrades to the site while it is still on the old developer's server (and without the old developer knowing about it)? Would the new developer have to create a mirror site and work on it that way? I'm having trouble imagining if this is possible so any advice you can offer would be much appreciated!

  • How to create an auto-grader in and for Python

    - by recluze
    I'm trying to create an auto-grader for one of my beginning programming courses for python. From my online search, I've come to know that it is effectively a unit test framework that tests the student's code rather than production code but I'm not really sure how to structure the flow of the program. Can anyone please provide a strategy for submission of code by students and automating the whole process of marking? For instance, how would the student code be submitted and then stored/structured on disk, how would the grades be stored/reported? I'm only looking for a broad strategy and will try on my own to fill in the blanks. (I asked this on stockoverflow.com initially but it's considered as off-topic and I was suggested to ask here.)

  • 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.

  • How to access files on a drive from an older system, mounted in a new system?

    - by David Thomas
    I've recently built a new system, after a rather large physical injury was sustained by my previous system (a precarious balance, and gravity, were not a happy mix). Surprisingly the /home drive of that system appears to have more-or-less survived the trauma. However... I decided to use a fresh drive for / (and swap) partition(s), and another fresh drive for the new /home. Now that's working, I decided to install the old /home drive (that I had assumed until now would be entirely dead and without capacity for use) into the new system to recover the files and data (so far as is possible). At this point I've run into a snag: I have no idea how to go about this (with Windows it was relatively easy, the new drive would be the latest character of the alphabet, and go from there). With 'disk utility' (System - Administration - Disk Utitlity) I've worked out which drive it is (/dev/sda) but clicking on 'mount' produces an error: 1: helper failed with: mount: according to mtab, /dev/sdb1 is already mounted on / mount failed ...if it is mounted on / I can't see it. I'm also moderately confused by the disk (device /dev/sda) being referred to as /dev/sdb1. Any and all insights would be incredibly welcome (I've already voted for: Idea #9063: New internal hard drives default automount at Brainstorm). Edited in response to Roland's request for a screenshot of disk utility: Details (so far as I know them): 40GB disk is / and swap, 1.0 TB Samsung is /home 1.0 TB Hitachi is from the old system (and was the old /home drive). Output from sudo fdisk -l pasted below: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000bef00 Device Boot Start End Blocks Id System /dev/sda1 1 121601 976760001 83 Linux Disk /dev/sdb: 40.0 GB, 40018599936 bytes 255 heads, 63 sectors/track, 4865 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00037652 Device Boot Start End Blocks Id System /dev/sdb1 * 1 4742 38084608 83 Linux /dev/sdb2 4742 4866 993281 5 Extended /dev/sdb5 4742 4866 993280 82 Linux swap / Solaris Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e8d46 Device Boot Start End Blocks Id System /dev/sdc1 1 121602 976760832 83 Linux

  • Org-mode lags in highlighting source

    - by quanticle
    I'm using org-mode to maintain my programming notes. This means I have lots of source code blocks, as follows. #+begin_src <language name> <code> #+end_src One thing I've noticed is that when I write the #+end_src, emacs doesn't color the source code as such. Yet, if I quit emacs and reopen the notes file (or force a refresh with the Org-Refresh/Reload-Refresh setup current buffer menu entry) the source is colored grey if I'm using the GUI or green if I'm using emacs in the terminal. Is this an inherent limitation of emacs, or am I doing something wrong in setting up my code blocks that's preventing emacs from going back and recoloring the source code that I've entered?

  • Parallelize incremental processing in Tabular #ssas #tabular

    - by Marco Russo (SQLBI)
    I recently came in a problem trying to improve the parallelism of Tabular processing. As you know, multiple tables can be processed in parallel, whereas the processing of several partitions within the same table cannot be parallelized. When you perform an incremental update by adding only new rows to existing table, what you really do is adding rows to a partition, so adding rows to many tables means adding rows to several partitions. The particular condition you have in this case is that every partition in which you add rows belongs to a different table. Adding rows implies using the ProcessAdd command; its QueryBinding parameter specifies a SQL syntax to read new rows, otherwise the original query specified for the partition will be used, and it could generate duplicated data if you don’t have a dynamic behavior on the SQL side. If you create the required XMLA code manually, you will find that the QueryBinding node that should be part of the ProcessAdd command has to be moved out from ProcessAdd in case you are using a Batch command with more than one Process command (which is the reason why you want to use a single batch: run multiple process operations in parallel!). If you use AMO (Analysis Management Objects) you will find that this combination is not supported, even if you don’t have a syntax error compiling the code, but you might obtain this error at execution time: The syntax for the 'Process' command is incorrect. The 'Bindings' keyword cannot appear under a 'Process' command if the 'Process' command is a part of a 'Batch' command and there are more than one 'Process' commands in the 'Batch' or the 'Batch' command contains any out of line related information. In this case, the 'Bindings' keyword should be a part of the 'Batch' command only. If this is happening to you, the best solution I’ve found is manipulating the XMLA code generated by AMO moving the Binding nodes in the right place. A more detailed description of the issue and the code required to send a correct XMLA batch to Analysis Services is available in my article Parallelize ProcessAdd with AMO. By the way, the same technique (and code) can be used also if you have the same problem in a Multidimensional model.

  • CRT as 2nd monitor goes screwy after start up?

    - by rhys
    new install of 12.04 on an old dell with a radeon ATI RV516 video card with monitor out and s-video out. During boot up all is good. Both screens operate and look fine. Then just before the desktop appears the cCRT goes purple and is covered in heavy horizontal lines, but as i said during boot up it was fine and the resolution was fine. The main monitor, an lcd, operates normally. everything else works fine, it's just the picture on the CRT that is screwed up. I used the same monitor and CRT running 11.10 which worked fine any help would be appreciated and yes i am a newbie to ubuntu here is a vid showing the completely normal screens at reboot then the purple badness when the desktop loads ?? and don't laugh at the slow machine, it's old. http://www.youtube.com/my_videos_edit?ns=1&video_id=zfuh6lBMLnc

  • Naming: objectAction or actionObject?

    - by DocSalvage
    The question, Stored procedure Naming conventions?, and Joel's excellent Making Wrong Code Look Wrong article come closest to addressing my question, but I'm looking for a more general set of criteria to use in deciding how to name modules containing code (classes, objects, methods, functions, widgets, or whatever). English (my only human language) is structured as action-object (i.e closeFile, openFile, saveFile) and since almost all computer languages are based on English, this is the most common convention. However, in trying to keep related code close together and still be able to find things, I've found object-action (i.e. fileClose, fileOpen, fileSave) to be very attractive. Quite a number of non-English human languages follow this structure as well. I doubt that one form is universally superior, but when should each be used in the pursuit of helping to make sure bad code looks bad?

  • Managing BES Software Configurations

    - by DaveJohnston
    Hi, I am having problems with OTA deployment of a bespoke application that we have written. I have read loads of threads elsewhere and I have got mixed help, but for my particular case none of it has really helped. So I thought I would explain my exact situation and try and get some help here. I am running BES version 4.1.5 (Bundle 79) for Microsoft Exchange. The application we have written is split into 5 modules, which we control, and another 4 modules which are 3rd party libraries that we require. So for our modules the version numbers are regularly changing but for the others they are pretty much always going to remain the same. We have an alx file set up that identifies all of the files required and in fact I am able to create a software configuration and deploy the application with no problems. What I am trying to do however is maintain multiple versions of our application on the BES and be able to select which version I want to deploy to each user. I have tried this a number of ways (as I said I have read lots of other threads with solutions to this problem) but each seems to come with its own problem. First of all I tried just creating different configurations for each version of the application, but because they each had the same application ID the BES informed me that I couldn't do this. I read somewhere that the solution was to create a second shared folder (e.g. \Program Files\Common Files\RIM) and add the apploader stuff and the new version of the app to this folder. I could then create a second software configuration that would have the same application ID. The result of this seemed promising to start with. When I changed the config that was assigned to a user the new version was pushed out fine. But afterwards the BES reported that the device state was invalid, which meant I couldn't push anything else until I reactivated the device. I guess this is because the first config was never set to disallowed so the old version wasn't removed and the device essentially reported that it had multiple versions of the same application installed. The next suggestion I got was to change the application ID for each version, e.g. to include the version number. This meant that each version of the application could be included in a single configuration and I could set one to disallowed and the other to required. Initially this worked and the first version was deployed. But when I switched (i.e. the old version became disallowed and the new version required) the BES reported upgrade required and removed the old version. The device restarts and the old version is gone but the new version is not pushed out. I checked the BES and it still said Upgrade Required. I checked the log files and found: [40000] (11/12 09:50:27.397):{0xEB8} {[email protected], PIN=1234, UserId=2}SCS::PollDBQueueNewRequests - Queuing POLL_FOR_MISSING_APPS request [40000] (11/12 09:50:28.241):{0xE9C} RequestHandler::PollForMissingApps: Starting Poll For Missing Apps.

(You will notice I have removed actual names and email addresses etc for privacy reasons. But one question: where does the name of the module group come from? In my case it is close to the application ID but doesn't include the version number that I added at the end in order to get it to work. Is that information embedded in a COD file or something??) So it is reporting a duplicate module group on the device? What does this mean? I checked the device properties (as reported on the BES) and it confirms that the modules with the old version numbers are still present on the device. So the application has been removed but not the modules?? I checked the device and the modules are gone, so it is just the BES reporting that they are still there?? I checked the database and it has the modules in questions in the SyncDeviceMgmt table. If I delete these from the DB the BES changes to report Install Required, and low and behold the new version of the app is pushed out. So at the end of all that, my question is: does anyone have any other suggestions of how to handle upgrading our bespoke application OTA from the BES? Or can anyone point out something I am doing wrong in what I described above that might solve the problems I am having? I guess the question is why does the database maintain that the modules are on the device after they are removed? Thanks for any help you can provide.

  • How do you properly organize a commercial game?

    - by Reactorcore
    For the past months I've been studying programming and I've finally learned how to code, but one thing that is confusing me is how to properly organize the design of a game project - code wise. The game I'm building is a pretty standard commercial game. It has the basic components of a normal game: A world, characters and items interacting with each other and all of this is run by game manager. Basically you play as a hero in a world and do stuff. Fight, explore and interact. Think of your standard adventure game that starts off with an intro, goes to the menu system, then gets into the game and back to the menu. Pretty much like 99% of any commercial game or otherwise serious game projects. Thats what I'm aiming at. The problem is: How do you properly code a commercial game architecture? How do you organize it? How do you make it not become unmaintainable spaghetti code? What specific things to keep in mind when building this, codewise? How you can help me: a) Please tell how do you code your own game projects. What is your thought-process when designing the architecture? b) Recommend books, blogs, tutorials, videos or anything else on how to organize a commercial video game. c) Give hints and tips on do's/don'ts when building a game, codewise. Please help!

  • GWT: Generate more complete crawl error report

    - by Mike
    I'm a developer in charge of managing Webmasters and related issues (including correcting crawl errors) for dozens (hundreds, maybe?) of active sites and as part of my duties I create a report of every discrepancy, including all pages generating a 404 and all pages that link to those pages. Currently within Webmaster Tools I'm able to download a csv file of all pages with a 404 response, but I'm then having to manually click on every single one of those links and copy the "linked from" field to paste into my spreadsheet. This is extremely tedious and seems unnecessary; I would expect the ability to download all that data at once. I'm ultimately looking for the end result of one csv file that has every url with a 404, but also has every url that links to each one of them. Am I overlooking this functionality somewhere or does anyone have a good solution? Edit 1 (2/11/2013): Example of what the csv output looks like now: URL,Response Code,News Error,Detected,Category http://www.abcdef.com/123.php,404,,11/12/13,Not found http://www.abcdef.com/456.php,404,,11/12/13,Not found Which is great, but let's say 123.php has 5 pages that link to it. Now I have to duplicate that row in my spreadsheet 4 more times, then go into Webmasters, get all the url's that link to the page, and add that data to my spreadsheet. The output I would prefer: URL,Response Code,Linked From,News Error,Detected,Category http://www.abcdef.com/123.php,404,http://www.ghijkl.com/naughtypage1.php,,11/12/13,Not found http://www.abcdef.com/123.php,404,http://www.ghijkl.com/naughtypage2.php,,11/12/13,Not found http://www.abcdef.com/123.php,404,http://www.ghijkl.com/naughtypage3.php,,11/12/13,Not found http://www.abcdef.com/456.php,404,http://www.ghijkl.com/naughtypage1.php,,11/12/13,Not found http://www.abcdef.com/456.php,404,http://www.ghijkl.com/naughtypage2.php,,11/12/13,Not found http://www.abcdef.com/456.php,404,http://www.ghijkl.com/naughtypage3.php,,11/12/13,Not found Note the (hypothetical) addition of a "Linked From" column, as well as the fact there are only 2 unique URL's now (like before) but all of the "Linked To" pages are shown in one report. Edit 2 (2/12/2013): To clarify, my question is less about detecting and correcting 404's, but more about generating a report of what Google has listed as errors. Oftentimes, these errors aren't even valid anymore but I still need documentation to show that Google detected a problem and that problem is now fixed. Many of the "linked from" url's I find are actually outdated, cached resources. For example, I'll frequently see that the linked-from url is the sitemap, which is actually an old sitemap cached by Google that points to an old page. Neither the sitemap or old page exist, but they still appear in my crawl error reports because they are cached resources.

  • GnuPG v1.4.10 cant read

    - by Nicky Bailuc
    I was thinking of "Getting Involved" with Ubuntu and decided to join the Bug Squad. After a few steps of joining, I got an email with a OpenPGP key licenced at Gnu version 1.4.10 and went on their website. They recommended me a couple of apps that can decode the code, but none of them worked, in fact each of them said that the code is corrupted. I thought that there's something wrong with that email, so I resent the request. As I got another email and tried the code with those programs, the programs said the same thing. How can I decode the code properly? Is there an online way of doing it? Any suggestions?

  • Packages don't show up after adding ppa

    - by user32993
    I added ppa:ubuntu-mozilla-daily/ppa/firefox-aurora/ubuntu oneiric and ppa:banshee-team/ppa/ubuntu oneiric to my software sources, then did apt-get update. However, after selecting their specific sources from the menu in Software Center, the only packages available are language packs and extensions for Banshee and firefox-aurora. I had already uninstalled Banshee and Firefox. If I try and install Banshee/Aurora with sudo apt-get it will install the old version. Searching for Banshee/Aurora in Software Center only shows the old version. I'm guessing the packages in the PPAs conflict with the packages in the main sources. How do I install the newer versions?

  • Switch Hosts With Gmail Account Attached

    - by Wade D Ouellet
    Hi, I am transferring a client from their old host to my new one. Their domain-based gmail/apps account was connected to their old host, so when I changed the domain's name servers to the new host, naturally the gmail account stopped working. So I added the 7 MX records tho the new host's DNS and verified I own the domain on the new host's FTP but the email still isn't working. Is there something I'm missing? I added the MX records to the new host about two hours ago, is it possible it just takes longer than that? Also, outgoing mail seems to work. Members of the domain can't receive email though, just sends back an error. Thanks, Wade

  • Some files not copied when moving an encrypted home to a different partition

    I have "successfully" moved my encrypted home to a separate partition using the instructions here: How can i move an encrypted home directory to another partition? However, some files are not being copied over. Most notably, I have a directory in my old home that contains the themes I use. This directory and it's contents are not copied over to the new home and therefore I come up with the default theme. Permissions on the directory that was not moved are identical to the other directories in home. Another discrepancy is that my Dropbox folder came over empty and had to resync itself. My concern is what else might be missing from the copied home. At this point, I've flipped back to the old home by re-editing /etc/fstab, but I'd really like to get /home cleanly and completely off of root without having to core the system.

  • Modularity through HTTP

    - by Michael Williamson
    As programmers, we strive for modularity in the code we write. We hope that splitting the problem up makes it easier to solve, and allows us to reuse parts of our code in other applications. Object-orientation is the most obvious of many attempts to get us closer to this ideal, and yet one of the most successful approaches is almost accidental: the web. Programming languages provide us with functions and classes, and plenty of other ways to modularize our code. This allows us to take our large problem, split it into small parts, and solve those small parts without having to worry about the whole. It also makes it easier to reason about our code. So far, so good, but now that we’ve written our small, independent module, for example to send out e-mails to my customers, we’d like to reuse it in another application. By creating DLLs, JARs or our platform’s package container of choice, we can do just that – provided our new application is on the same platform. Want to use a Java library from C#? Well, good luck – it might be possible, but it’s not going to be smooth sailing. Even if a library exists, it doesn’t mean that using it going to be a pleasant experience. Say I want to use Java to write out an XML document to an output stream. You’d imagine this would be a simple one-liner. You’d be wrong: import org.w3c.dom.*; import java.io.*; import javax.xml.transform.*; import javax.xml.transform.dom.*; import javax.xml.transform.stream.*; private static final void writeDoc(Document doc, OutputStream out) throws IOException { try { Transformer t = TransformerFactory.newInstance().newTransformer(); t.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, doc.getDoctype().getSystemId()); t.transform(new DOMSource(doc), new StreamResult(out)); } catch (TransformerException e) { throw new AssertionError(e); // Can't happen! } } Most of the time, there is a good chance somebody else has written the code before, but if nobody can understand the interface to that code, nobody’s going to use it. The result is that most of the code we write is just a variation on a theme. Despite our best efforts, we’ve fallen a little short of our ideal, but the web brings us closer. If we want to send e-mails to our customers, we could write an e-mail-sending library. More likely, we’d use an existing one for our language. Even then, we probably wouldn’t have niceties like A/B testing or DKIM signing. Alternatively, we could just fire some HTTP requests at MailChimp, and get a whole slew of features without getting anywhere near the code that implements them. The web is inherently language agnostic. So long as your language can send and receive text over HTTP, and probably parse some JSON, you’re about as well equipped as anybody. Instead of building libraries for a specific language, we can build a service that almost every language can reuse. The text-based nature of HTTP also helps to limit the complexity of the API. As SOAP will attest, you can still make a horrible mess using HTTP, but at least it is an obvious horrible mess. Complex data structures are tedious to marshal to and from text, providing a strong incentive to keep things simple. By contrast, spotting the complexities in a class hierarchy is often not as easy. HTTP doesn’t solve every problem. It probably isn’t such a good idea to use it inside an inner loop that’s executed thousands of times per second. What’s more, the HTTP approach might introduce some new problems. We often need to add a thin shim to each application that we wish to communicate over HTTP. For instance, we might need to write a small plugin in PHP if we want to integrate WordPress into our system. Suddenly, instead of a system written in one language, we’re maintaining a system with several distinct languages and platforms. Even then, we should strive to avoid re-implementing the same old thing. As programmers, we consistently underestimate both the cost of building a system and the ongoing maintenance. If we allow ourselves to integrate existing applications, even if they’re in unfamiliar languages, we save ourselves those development and maintenance costs, as well as being able to pick the best solution for our problem. Thanks to the web, HTTP is often the easiest way to get there.
