  • Is there a Javascript library for creating vintage photos?

    - by Nguyen Thanh Tu
    I'm working on a Canvas object in HTML5, and I am attempting to make some photos look "better". I tried VintageJS, an existing photo-retouching Javascript library, and Picozu, a web application cloning some Adobe Photoshop functionalities, but I'm still not happy. Can you help me with an algorithm or point to an existing Javascript library that would allow me to make my photos look like the following example? http://i46.photobucket.com/albums/f137/thanhtu_zx/Untitled-1.jpg

  • Is is good or bad to have the email address of a domain's registrant on the same domain?

    - by Eric Nguyen
    Say I own domain abc.com. I think it's a bad idea to use [email protected] as the registrant's (myself) email address. This will cause problems when I need to transfer the domain to another registrar e.g. GoDaddy. The new registrar will then try to send email to [email protected] which is unlikely to function normally since the DNS settings are undergoing changes. So I believe it's best to use email address independent from the domains I own as the registrant's email address. (Isn't it the practice Google Apps is using?) Have I missed something here or am I right?

  • WD external hard drive not detected

    - by Khang Nguyen
    I am a beginner in Ubuntu. And I have just installed Ubuntu 11.10 in my Dell laptop. When I plugged my WD external hard drive in, it read the first time, but since I have a unlock.exe file (password for the hard drive). So I installed Wine to read it. But it gives me an error. I restart the machine, and plugged the hard drive in again. And it is not recognized anymore. Can anybody help me, please? Thank you!

  • Avoid SEO loss after URL structure change

    - by Eric Nguyen
    We recently re-wrote our site from Umbraco to WordPress. This has been done by third-party developers. I have been the project manager and it is my mistake that I haven't notice the change of URLs that affect SEO until now. New site was launch last Thursday. The old URL for a "place" (a WordPress custom post type, in case you're WordPress expert and want/ need to point me to another discussion on WP Stackexchange) page is as follows: ourdomain.com/singapore/central/alexandra/an-interesting-place Now it has been changed to ourdomain.com/places/an-interesting-place I have already requested the third-party developers to work rewriting the URLs to emulate the old URL structure. However, it's taking quite a lot of time (we have multiple custom post types e.g. events etc. so it might be complicated; the developers seem quite by blur when I first mentioned rewriting URLs for the custom post types) In the meantime, I wonder if there is a quicker work around for this 1) Use .htaccess to rewrite ourdomain.com/singapore/central/alexandra/an-interesting-place to ourdomain.com/places/an-interesting-place This should avoid 90% loss of the search traffic. I suppose I can learn how to do this quite quickly but no harm mentioning it here 2) Use rel="canonical" to indicate that ourdomain.com/places/an-interesting-place is the exact duplicate of ourdomain.com/singapore/central/alexandra/an-interesting-place I will definitely go for both approaches (and also I'm changing 404 page to cater for this temporary isue) but I wonder if 2) is even feasible and if I have missed anything. Is there anything else you could recommend me in this situation. Let me know if my question is not clear anywhere. Clarifications The old website is on a Windows Server EC2 completely separated from the Linux EC2 instance on which the new site is running. In addition, the same domain "ourdomain.com" is used here (an A record is used to point to an EC2 Elastic IP). Therefore, the old server is completely inaccessible at the moment, unless you we use the IP address to old server (which doesn't help me at all in this case). Even if the old server is accessible, I can't see where one can put the .htaccess or a HTML file to do 301 redirect here. Unless I'm successful with my approach 1) or the developers can rewrite the URLs with coding, 404 page is really a choice for me.

  • How To Build An Enterprise Application - Introduction

    - by Tuan Nguyen
    An enterprise application is a software which fulfills 4 core quality attributes: Reliability Flexibility Reusability Maintainability Reliability is the ability of a system or component to perform its required functions under stated conditions for a specific period of time. Because there are no ways more than testing to make sure a system is reliability, we can exchange the term reliability with the term testability. Flexibility is the ability of changing a system's core features without violating unrelated features or components. Although flexibility can helps us to achieve interoperability easily but the opposite is not true. For example, a program might run on multiple platforms, contains logic for many scenarios but that wouldn't mean it was flexibility if it forces us rewrite code in all components when we just want to change some aspects of a feature it had. Reusability is the ability of sharing one or more system's components for another system. We should just open a component's reusability in the context in which it is used. For example, we write classes that implement UI logic and deliver them to only classes which implementing UI. Maintainability is the ability of adding or removing features to a system after it was released. Maintainability consists of many factors such as readability, analyzability, extensibility therein extensibility is critical. Maintainability requires us to write code that is longer and complexer than normal but it doesn't mean we introduce unneccessarily complex code. We always try to make our code clear and transparent to everyone. An application enterprise is built on an enterprise design which consists of two parts: low-level design and high-level design. At low-level design, it focuses on building loose-coupled classes or components. Particularly, it recommends: Each class or component undertakes only single responsibility (design based on unit test) Classes or components implement and work through interfaces (design based on contract) Dependency relationship between classes and components could be injected at run-time (design based on dependency) At high-level design, it focuses on architecting system into tiers and layers. Particularly, it recommends: Divide system into subsystems for deployment. Each subsytem is called a tier. Typical, an enterprise application would have 3 tiers as illustrated in the following figure: Arrange classes and components to logical containers called layers. Typical, an enterprise application would have 5 layers as illustrated in the following figure

  • Transfer .com domain to GoDaddy - websites running on same domain - 3 weeks left until expiration, 2 days left web hosting

    - by Eric Nguyen
    Our company purchased this abc.com domain from a local registrar. The domain will expire in about 3 weeks. We have our main websites running on this abc.com domain and they cannot be down for too long. The web hosting service will end in 2 days. Our websites are already hosted and they are up and running on Amazon EC2. We would like to transfer the domain to GoDaddy now or as soon as possible. (since we have many other domains there and we belive GoDaddy will be better in long-term considering the prices and the features it offers) There are many questions on the decision to transfer the domain to GoDaddy: 1) Cost and time required to move out of our local registrar? This is currently unknown as I'm still trying to retrieve the agreement we have with them 2) How does the 3 week time left until expiration of the domain matters here? Should we wait until the domain expires and then purchase in through GoDaddy? How long would such process take as I suppose our websites will be down during that time? Any other drawbacks? 3) What can I do to ensure our websites will continue functioning regardless of the domain transfer process? It seems the actual registrar here is enom.com and the local registrar here just partners with it I suppose I should then park the abc.com domain with enom.com and make changes to DNS settings so that our websites can continue to be hosted on EC2 as normal. How long does it normally take the domain to be transferred to GoDaddy completely? Is it even possible at all to keep our websites are up and running during the whole domain transfer process? Apologies that I'm throwing many questions at the same time here. It's rather last minutes and I suddenly realised there are too many unknown risks.

  • Economical DNS hosting separate from local registrar for country specific TLDs - email or web hosting not required

    - by Eric Nguyen
    Our company owns many country specific top level domains (TLDs; .sg, .my). We will purchase more for other countries in all South East Asia. These domains are associated with our websites hosted on Amazon EC2. The DNS records are currently hosted on a dedicated server that will shut down tomorrow. (The name servers are set to the ones of a web hosting company) Therefore, I will need to host the DNS records somewhere else. Hosting the DNS records with the local registrar costs SGD18 a year per domain in addition to the domain price (which is already very expensive but we have no choice). It would be convenience to host DNS recors for all the country specific TLDs we have using a single service, separate from the local registrars from which we bought the domains. A few searches prompted examples like Amazon Route 53 and dnsmadeeasy.com and the likes. However, since I'm only concern about the country specific TLDs, not .com 1) Is it really economical to host DNS records of all domains in 1 single place as described above? (Have the relevant countries and/or the local registrars done something to keep their monopoly and always charges ridiculous prices for their country specific TLDs?) 2) I would imagine I will need to tell the local registrars to update the name servers to those of the DNS hosting service provider e.g. dnsmadeeasy.com here. Am I correct about how it works here? 3) Will I be able point the TLDs themselves to IP addresses I desire (the EC2 instances where my websites are) or will I only able to do so with the subdomains? 4) Are there any drawbacks that I should know here? Background about our needs: We need the websites associated with the country TLDs to be up and running all the times Also, we'll need to be able to add/edit A and CNAME records We use Google Apps for Business for internal email so I will need to be able to add/edit MX records and TXT records

  • 1 Google Analytics account or top-level domain + profiles for sub-domains vs. 1 account for each sub-domain

    - by Eric Nguyen
    We have the following websites An online magazine Singapore edition - sg.abc.com The same online magazine Malaysia edition - my.abc.com Forums around the same subjects as the online magazine but functions independently - forums.abc.com Classifieds site rather also around the same subjects but functions independently - directory.abc.com Each of the above websites currently has its own Google Analytics account. abc.com has a separate Google Analytics account too. sg.abc.com has the most traffic and generates most revenues Are there any practical benefits of merging all the above sub-domains to be under abc.com? I can think of more reliable analytics and consistency for sure. Are there more? cross-sales?

  • Is there a more intelligent way to do this besides a long chain of if statements or switch?

    - by Harrison Nguyen
    I'm implementing an IRC bot that receives a message and I'm checking that message to determine which functions to call. Is there a more clever way of doing this? It seems like it'd quickly get out of hand after I got up to like 20 commands. Perhaps there's a better way to abstract this? public void onMessage(String channel, String sender, String login, String hostname, String message){ if (message.equalsIgnoreCase(".np")){ // TODO: Use Last.fm API to find the now playing } else if (message.toLowerCase().startsWith(".register")) { cmd.registerLastNick(channel, sender, message); } else if (message.toLowerCase().startsWith("give us a countdown")) { cmd.countdown(channel, message); } else if (message.toLowerCase().startsWith("remember am routine")) { cmd.updateAmRoutine(channel, message, sender); } }

  • How to "kill" background worker completely?

    - by Ken Hung
    Hi All, I am writing a windows application that runs a sequence of digital IO actions repeatedly. This sequence of actions starts when the user click a "START" button, and it is done by a background worker in backgroundWorker1_DoWork(). However, there are occasions when I get the "This backgroundworker is currently busy......." error message. I am thinking of implementing the following in the code, by using a while loop to "kill" the background worker before starting another sequence of action: if (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); while (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); } backgroundWorker1.Dispose(); } backgroundWorker1.RunWorkerAsync(); I think my main concern is, will the backgroundWorker1 be "killed" eventually? If it will, will it take a long time to complete it? Will this coding get me into an infinite loop?

  • Formatting Parameters for Ajax POST request to Rails Controller - for jQuery-UI sortable list

    - by Hung Luu
    I'm using the jQuery-UI Sortable Connected Lists. I'm saving the order of the connected lists to a Rails server. My approach is to grab the list ID, column ID and index position of each list item. I want to then wrap this into an object that can be passed as a parameter back to the Rails Controller to be saved into the database. So ideally i'm looking to format the parameter like this: Parameters: {"Activity"=>[{id:1,column:2,position:1},{id:2,column:2,position:2} ,...]} How do I properly format my parameters to be passed in this Ajax POST request? Right now, with the approach below, I'm passing on Parameters: {"undefined"=>""} This is my current jQuery code (Coffeescript) which doesn't work: jQuery -> $('[id*="day"]').sortable( connectWith: ".day" placeholder: "ui-state-highlight" update: (event, ui) -> neworder = new Array() $('[id*="day"] > li').each -> column = $(this).attr("id") index = ui.item.index() + 1 id = $("#" + column + " li:nth-child(" + index + ") ").attr('id') passObject={} passObject.id = id passObject.column = column passObject.index = index neworder.push(passObject) alert neworder $.ajax url: "sort" type: "POST" data: neworder ).disableSelection() My apologies because this seems like a really amateur question but I'm just getting started with programming jQuery and Javascript.

  • Can't clone gitosis-admin.git local from my snow leopard server running gitosis

    - by joggink
    I've installed gitosis as described here: http://gist.github.com/264304 One of the things that I had to adjust was to give my git user permissions to use ssh (which I did trough server admin - access - ssh and added the 'git' user). When I ssh from my local machine (mac osx) as the git user, I get this response: PTY allocation request failed on channel 0 bash: gitosis-serve: command not found Connection to 10.0.0.108 closed. Which I think is normal, because in Pro GIT the author says you should get something like this if you try ssh'ing to the server using your git user: PTY allocation request failed on channel 0 fatal: unrecognized command 'gitosis-serve schacon@quaternion' Connection to gitserver closed. So far so good, I think? Now when I try to clone my gitosis-admin.git repository using this command: $git clone [email protected]:gitosis-admin.git I get this: Initialized empty Git repository in /Users/joggink/gitosis-admin/.git/ bash: gitosis-serve: command not found fatal: The remote end hung up unexpectedly So after doing some searching, I found an answer here on serverfault claiming I should use ssh:// as protocol for my git clone (which I thought is the default git protocol?) However, when I try: $git clone ssh://[email protected]:gitosis-admin.git This is the response: The authenticity of host ' (::1)' can't be established.

  • Seeking past end of file causes Apache hang, and it never restarts.

    - by talkingnews
    I've actually solved my problem with a better script, but I'm still left wondering why Apache2 hung completely - this is an out-of-the-box ISPCONFIG 3.03 install, everything bang up to date, running perfectly. Until... The troublesome but innocent-looking script: $fp = fopen("/var/log/ispconfig/cron.log", "r"); fseek($fp, -5000, SEEK_END); $line_buffer = array(); while (!feof($fp)) { $line = fgets($fp, 1024); $line_buffer[] = $line; $line_buffer = array_slice($line_buffer, -10, 10); } foreach ($line_buffer as $line) { echo $line; } You get the idea, just a script I found on a forum somwehere. I did this for various logs, since it's a nice easy window on what's occurring (in a protect dir, of course!). One day, the logs having grown large an me having sorted all my cron, scripting and mail queue errors, I thought I was time to start afresh. updated, rebooted, archived and deleted the logs. When I ran my script a couple of hours later, it hung. And hung. 8 minutes I waited. Chrome timed the page out, of course, but the server never came back to life. htop showed /usr/sbin/apache2 -k restart using 100% CPU. Never came back until I did a service apache2 restart. Ran fine, as soon as I hit that logfile again...dead. So, I worked out it was the logfile script, and I worked out that seeking beyond the end of the file wasn't good, and I found a better script http://www.php.net/manual/en/function.fseek.php#90450 But what I'm left wondering is... why didn't something restart or kill the process? How was one hanging page able to bring down the whole server? It's running suphp. I say "out of the box", I've tweaked mysql and apache to fork and reserve sensible amounts of processes for the 512Mb RAM the VPS has, and it'll handle multiple refreshes of large pages, and hadn't hung before. Any ideas how I'd avoid this? Google isn't my friend in this instance beyond the reccs. above about number of processes vs RAM available.

  • Video Freezes Every few seconds

    - by Chandan
    Hi, I have problems playing videos on my Ubuntu 10.10 machine. The video FREEZES every 20-25 seconds, while I could still hear the audio. I use Totem Movie Player (GStreamer) & have nVidia on-board graphics card & AMD DualCore processor. After some 5-10 seconds, the videos resumes skipping the hung portion. But, I can hear the audio of that part! I've tried it with SMPlayer (GUI), VLC & Kaffeine. But, the same problem... I recently uninstalled the nVidia drivers and since then, not even for a second, no video hung! So, I thought its the problem with the proprietary nVidia drivers. But, since its uninstalled, I'm not able to get the desired desktop resolution & effects. So, is there any way I can work it out?

  • Diagnosing SAN connectivity issues (RHEL5)

    - by Matthew
    We are currently utilizing GFS2 to share a SAN LUN between 3 servers. However due to a feature problem with vendor software we are using, we currently have the volume unmounted on two of the boxes, and are instead exporting the GFS2 filesystem via NFS from the first one (the software requires some weird locking mechanics that GFS2 doesn't support). As of this morning, NFS was no longer able to read/write to the volume from any of the servers, including the NFS server. I then tried checking the normal mount (the directory that is exported on the NFS server) and I received a weird input/output error just trying to CD into it. When I tried running multipath, I got a DM error, however multipath -l worked just fine. I tried unmounting the GFS2 volume, and the CLI hung. I ran init 0 which killed most services, but then the shutdown appeared to have been hung. I logged in via out of band access (hp ILO) and saw that the shutdown was hung trying to unmount GFS2 volumes. My main priority was getting the box back online so after about 5 minutes of waiting I did a hard reset. I am now trying to figure out what went wrong. What are the correct logs to investigate? I've never run into SAN issues like this before. The SAN is connected via 2 fibre connections. Any help would really be appreciated. Everything appears to be up and functional now.

  • Randomly displayed flashing lines, no response to all shortcuts, just power off. [syslog included]

    - by B. Roland
    Hello! I have an old machine, and I want to use for that to learn employees how to use Ubuntu, and to be easyer to switch from Windows. I've been installed 10.04, and updated, but this strange stuff is happend. Graphical installion failed, same strange thing. With alternate workd. Sometimes, when I boot up, a boot message displayed: Keyboard failure..., often diplayed after reboot, and after shutdown, when I haven't plugged off from AC. I replaced the keyboard yet, same failure... If I powered off, and plugged off from AC, no keyboard problems displayed in boot time. Details Configuration: Dell OptiPlex GX60 - in original cover, no changes. 256 MB DDR 166 MHz Intel® Celeron® Processor 2.40 GHz Dell 0C3207 Base Board I know, that is not enough, but I have three other Nec compuers, with nearly similar config, and they works well with 9.10, 10.04, 10.10. Live CDs I've been tried with 10.04 and 10.10, but the problem is displayed too. With 9.10 no strange things displayed, but it froze, during a simple apt-get install. Syslog An error loop is logged here, but I paste the whole startup and error lines. The flashing lines are displayed sometimes immediately after login, but sometimes after 10 minutes, but once occured, that nothing happend. Strange thing is displayed immediately after login: here. An other boot, after some minutes, strange lines, and loop in log appeard: here. The loop should be that: Jan 23 00:20:08 machine_name kernel: [ 46.782212] [drm:i915_gem_entervt_ioctl] *ERROR* Reenabling wedged hardware, good luck Jan 23 00:20:08 machine_name kernel: [ 47.100033] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
