• How To Make Hundreds of Complex Photo Edits in Seconds With Photoshop Actions

  - by Eric Z Goodnight

  Have a huge folder of images needing tweaks? A few hundred adjustments may seem like a big, time consuming job—but read one to see how Photoshop can do repetitive tasks automatically, even if you don’t know how to program! Photoshop Actions are a simple way to program simple routines in Photoshop, and are a great time saver, allowing you to re-perform tasks over and over, saving you minutes or hours, depending on the job you have to work on. See how any bunch of images and even some fairly complicated photo tweaking can be done automatically to even hundreds of images at once. When Can I use Photoshop Actions? Photoshop actions are a way of recording the tools, menus, and keys pressed while using the program. Each time you use a tool, adjust a color, or use the brush, it can be recorded and played back over any file Photoshop can open. While it isn’t perfect and can get very confused if not set up correctly, it can automate editing hundreds of images, saving you hours and hours if you have big jobs with complex edits. The image illustrated above is a template for a polaroid-style picture frame. If you had several hundred images, it would actually be a simple matter to use Photoshop Actions to create hundreds of new images inside the frame in almost no time at all. Let’s take a look at how a simple folder of images and some Image editing automation can turn lots of work into a simple and easy job. Creating a New Action Actions is a default part of the “Essentials” panel set Photoshop begins with as a default. If you can’t see the panel button under the “History” button, you can find Actions by going to Window > Actions or pressing Alt + F9. Click the in the Actions Panel, pictured in the previous illustration on the left. Choose to create a “New Set” in order to begin creating your own custom Actions. Name your action set whatever you want. Names are not relevant, you’ll simply want to make it obvious that you have created it. Click OK. Look back in the layers panel. You’ll see your new Set of actions has been added to the list. Click it to highlight it before going on. Click the again to create a “New Action” in your new set. If you care to name your action, go ahead. Name it after whatever it is you’re hoping to do—change the canvas size, tint all your pictures blue, send your image to the printer in high quality, or run multiple filters on images. The name is for your own usage, so do what suits you best. Note that you can simplify your process by creating shortcut keys for your actions. If you plan to do hundreds of edits with your actions, this might be a good idea. If you plan to record an action to use every time you use Photoshop, this might even be an invaluable step. When you create a new Action, Photoshop automatically begins recording everything you do. It does not record the time in between steps, but rather only the data from each step. So take your time when recording and make sure you create your actions the way you want them. The square button stops recording, and the circle button starts recording again. With these basics ready, we can take a look at a sample Action. Recording a Sample Action Photoshop will remember everything you input into it when it is recording, even specific photographs you open. So begin recording your action when your first photo is already open. Once your first image is open, click the record button. If you’re already recording, continue on. Using the File > Place command to insert the polaroid image can be easier for Actions to deal with. Photoshop can record with multiple open files, but it often gets confused when you try it. Keep your recordings as simple as possible to ensure your success. When the image is placed in, simply press enter to render it. Select your background layer in your layers panel. Your recording should be following along with no trouble. Double click this layer. Double clicking your background layer will create a new layer from it. Allow it to be renamed “Layer 0” and press OK. Move the “polaroid” layer to the bottom by selecting it and dragging it down below “Layer 0” in the layers panel. Right click “Layer 0” and select “Create Clipping Mask.” The JPG image is cropped to the layer below it. Coincidentally, all actions described here are being recorded perfectly, and are reproducible. Cursor actions, like the eraser, brush, or bucket fill don’t record well, because the computer uses your mouse movements and coordinates, which may need to change from photo to photo. Click the to set your Photograph layer to a “Screen” blending mode. This will make the image disappear when it runs over the white parts of the polaroid image. With your image layer (Layer 0) still selected, navigate to Edit > Transform > Scale. You can use the mouse to resize your Layer 0, but Actions work better with absolute numbers. Visit the Width and Height adjustments in the top options panel. Click the chain icon to link them together, and adjust them numerically. Depending on your needs, you may need to use more or less than 30%. Your image will resize to your specifications. Press enter to render, or click the check box in the top right of your application. + Click on your bottom layer, or “polaroid” in this case. This creates a selection of the bottom layer. Navigate to Image > Crop in order to crop down to your bottom layer selection Your image is now resized to your bottommost layer, and Photoshop is still recording to that effect. For additional effect, we can navigate to Image > Image Rotation > Arbitrary to rotate our image by a small tilt. Choosing 3 degrees clockwise , we click OK to render our choice. Our image is rotated, and this step is recorded. Photoshop will even record when you save your files. With your recording still going, find File > Save As. You can easily tell Photoshop to save in a new folder, other than the one you have been working in, so that your files aren’t overwritten. Navigate to any folder you wish, but do not change the filename. If you change the filename, Photoshop will record that name, and save all your images under whatever you type. However, you can change your filetype without recording an absolute filename. Use the pulldown tab and select a different filetype—in this instance, PNG. Simply click “Save” to create a new PNG based on your actions. Photoshop will record the destination and the change in filetype. If you didn’t edit the name of your file, it will always use the variable filename of any image you open. (This is very important if you want to edit hundreds of images at once!) Click File > Close or the red “X” in the corner to close your filetype. Photoshop can record that as well. Since we have already saved our image as a JPG, click “NO” to not overwrite your original image. Photoshop will also record your choice of “NO” for subsequent images. In your Actions panel, click the stop button to complete your action. You can always click the record button to add more steps later, if you want. This is how your new action looks with its steps expanded. Curious how to put it into effect? Read on to see how simple it is to use that recording you just made. Editing Lots of Images with Your New Action Open a large number of images—as many as you care to work with. Your action should work immediately with every image on screen, although you may have to test and re-record, depending on how you did. Actions don’t require any programming knowledge, but often can get confused or work in a counter-intuitive way. Record your action until it is perfect. If it works once without errors, it’s likely to work again and again! Find the “Play” button in your Actions Panel. With your custom action selected, click “Play” and your routine will edit, save, and close each file for you. Keep bashing “Play” for each open file, and it will keep saving and creating new files until you run out of work you need to do. And in mere moments, a complicated stack of work is done. Photoshop actions can be very complicated, far beyond what is illustrated here, and can even be combined with scripts and other actions, creating automated creation of potentially very complex files, or applying filters to an entire portfolio of digital photos.

• Is it reasonable to expect knowing the whole stack bottom up?

  - by Vaibhav Garg

  I am an Sr. developer/architect/Product Manager for embedded systems. The systems that I have had experience with have typically been small to medium size codebases - typically close to 25-30K LOC in C, using 8-16 and 32 bit low end microcontrollers. The systems have been entirely bootstrapped by our team - meaning right from the start-up code to the end application code has either been written by the team, or at the very least, is thoroughly understood and maintained by us. Now, if we were to start developing more complex systems with complex peripherals, such as USB OTG et al. (think, low end cell phones), there are libraries and stacks available commercially and from chip vendors that reduce the task to just calling the right APIs and being able to use those peripherals. Now, from a habit point of view, this does not give me and the team a comfortable feeling, not being able to comprehend the entire code tree, with virtual black boxes at the lower layers. Is it reasonable to devote, and reserve, time getting into the details of how the APIs are implemented, assuming that the same would also entail getting into details of relevant standards (again, for USB as an example)? Or, alternatively, should a thorough understanding of the top level usage of the APIs be sufficient? This of course assumes that the source codes to all libraries are available, which they are, in almost all cases. Edit: In partial response to @Abhi Beckert, the documentation is refreshingly very comprehensive and meticulously maintained, AFAIK and been able to judge. I have not had a long experience with the same.

• Is there a measure of code rot?

  - by DarenW

  I'm dealing, again, with a messy C++ application, tons of classes with confusing names, objects have pointers into each other and all over, longwinded Boost and STL data types, etc. (Pause and consider your favorite terror of messy legacy code. We probably have it.) The phrase "code rot" oft comes to mind when I work on this project. Is there a quantitative way to measure code rot? I wouldn't expect anything highly meaningful or scientific, since no other measure of code productivity or quality is so fine. I'm not looking for a mere opposite of measures of code quality, but specifically a measure of how many bad things happened after a series of maintenance software "engineers" have had turns hacking at the code. A general measure applying to any language, or many languages, would be great. If there's no such thing, at least for C++, which is a better than average language for creating messes. Maybe something involving a measure of topology of how objects connect during runtime, a count of chunks of commented out code, how mane files a typical variable's usage is scattered over, I don't know... but surely now, a decade into the 21st Century, someone has attempted to define some sort of rot measure. It would be especially interesting to automate a series of svn checkouts, measure the "rottenosity" of each, and plot the decay over time.

• Building a common syntax and scoping framework.

  - by Ben DeMott

  Hello fellow programmers, I was discussing a project the other day with a colleague of mine and I was curious to see what others had to say or if such a thing already existed. Background There are many programming languages. There are many IDE's and source editors that highlight and edit source code. Following perfectly and exactly the rules of a language to present auto-complete options and understand scopes in the code is rather complex. This task is complex enough that most IDE's implement different source-editors as plugins that often re-implement the same features over and over but in a different way (netbeans). From what I can tell most IDE's and source editors re-implement parsers that use regular expressions, or some meta-syntax Naur Form to describe the languages grammer generically. These parsers are implemented over and over and over again. Question Has anyone attempted to unify or describe a set of features through an API and have a consistent interface to parsing various programming languages and dialects. I'm not describing an IDE - but a consistent API for any program to use to parse and obtain meta-information from the source code. I realize various programming languages offer many different features which are difficult to 'abstract' into a set of features, but I feel this would be a worthwhile venture. It seems to me that this could possibly allow the authors of interpreters to help maintain a central grammer intepreter for their language. the Python foundation could maintain the Python grammer api, ANSI the C grammer api, Oracle the Java grammer API, etc Example usage If this was API existed code documentation generators could theoretically work across all dialects and languages to some level. It wouldn't matter if your project used 5 different languages a single application could document all of them and the comments and doc-tags within. Has anyone attempted this comprehensively?

• Going Paperless

  - by Jesse

  One year ago I came to work for a company where the entire development team is 100% “remote”; we’re spread over 3 time zones and each of us works from home. This seems to be an increasingly popular way for people to work and there are many articles and blog posts out there enumerating the advantages and disadvantages of working this way. I had read a lot about telecommuting before accepting this job and felt as if I had a pretty decent idea of what I was getting into, but I’ve encountered a few things over the past year that I did not expect. Among the most surprising by-products of working from home for me has been a dramatic reduction in the amount of paper that I use on a weekly basis. Hoarding In The Workplace Prior to my current telecommute job I worked in what most would consider pretty traditional office environments. I sat in cubicles furnished with an enormous plastic(ish) modular desks, had a mediocre (at best) PC workstation, and had ready access to a seemingly endless supply of legal pads, pens, staplers and paper clips. The ready access to paper, countless conference room meetings, and abundance of available surface area on my desk and in drawers created a perfect storm for wasting paper. I brought a pad of paper with me to every meeting I ever attended, scrawled some brief notes, and then tore that sheet off to keep next to my keyboard to follow up on any needed action items. Once my immediate need for the notes was fulfilled, that sheet would get shuffled off into a corner of my desk or filed away in a drawer “just in case”. I would guess that for all of the notes that I ever filed away, I might have actually had to dig up and refer to 2% of them (and that’s probably being very generous). That said, on those rare occasions that I did have to dig something up from old notes, it was usually pretty important and I ended up being very glad that I saved them. It was only when I would leave a job or move desks that I would finally gather all those notes together and take them to shredding bin to be disposed of. When I left my last job the amount of paper I had accumulated over my three years there was absurd, and I knew coworkers who had substance-abuse caliber paper wasting addictions that made my bad habit look like nail-biting in comparison. A Product Of My Environment I always hated using all of this paper, but simply couldn’t bring myself to stop. It would look bad if I showed up to an important conference room meeting without a pad of paper. What if someone said something profound! Plus, everyone else always brought paper with them. If you saw someone walking down the hallway with a pad of paper in hand you knew they must be on their way to a conference room meeting. Some people even had fancy looking portfolio notebook sheaths that gave their legal pads all the prestige of a briefcase. No one ever worried about running out of fresh paper because there was an endless supply, and there certainly was no shortage of places to store and file used paper. In short, the traditional office was setup for using tons and tons of paper; it’s baked into the culture there. For that reason, it didn’t take long for me to kick the paper habit once I started working from home. In my home office, desk and drawer space are at a premium. I don’t have the budget (or the tolerance) for huge modular office furniture in my spare bedroom. I also no longer have access to a bottomless pit of office supplies stock piled in cabinets and closets. If I want to use some paper, I have to go out and buy it. Finally (and most importantly), all of the meetings that I have to attend these days are “virtual”. We use instant messaging, VOIP, video conferencing, and e-mail to communicate with each other. All I need to take notes during a meeting is my computer, which I happen to be sitting right in front of all day. I don’t have any hard numbers for this, but my gut feeling is that I actually take a lot more notes now than I ever did when I worked in an office. The big difference is I don’t have to use any paper to do so. This makes it far easier to keep important information safe and organized. The Right Tool For The Job When I first started working from home I tried to find a single application that would fill the gap left by the pen and paper that I always had at my desk when I worked in an office. Well, there are no silver bullets and I’ve evolved my approach over time to try and find the best tool for the job at hand. Here’s a quick summary of how I take notes and keep everything organized. Notepad++ – This is the first application I turn to when I feel like there’s some bit of information that I need to write down and save. I use Launchy, so opening Notepad++ and creating a new file only takes a few keystrokes. If I find that the information I’m trying to get down requires a more sophisticated application I escalate as needed. The Desktop – By default, I save every file or other bit of information to the desktop. Anyone who has ever had to fix their parents computer before knows that this is a dangerous game (any file my mother has ever worked on is saved directly to the desktop and rarely moves anywhere else). I agree that storing things on the desktop isn’t a great long term approach to keeping organized, which is why I treat my desktop a bit like my e-mail inbox. I strive to keep both empty (or as close to empty as I possibly can). If something is on my desktop, it means that it’s something relevant to a task or project that I’m currently working on. About once a week I take things that I’m not longer working on and put them into my ‘Notes’ folder. The ‘Notes’ Folder – As I work on a task, I tend to accumulate multiple files associated with that task. For example, I might have a bit of SQL that I’m working on to gather data for a new report, a quick C# method that I came up with but am not yet ready to commit to source control, a bulleted list of to-do items in a .txt file, etc. If the desktop starts to get too cluttered, I create a new sub-folder in my ‘Notes’ folder. Each sub-folder’s name is the current date followed by a brief description of the task or project. Then all files related to that task or project go into that sub folder. By using the date as the first part of the folder name, these folders are automatically sorted in reverse chronological order. This means that things I worked on recently will generally be near the top of the list. Using the built-in Windows search functionality I now have a pretty quick and easy way to try and find something that I worked on a week ago or six months ago. Dropbox – Dropbox is a free service that lets you store up to 2GB of files “in the cloud” and have those files synced to all of the different computers that you use. My ‘Notes’ folder lives in Dropbox, meaning that it’s contents are constantly backed up and are always available to me regardless of which computer I’m using. They also have a pretty decent iPhone application that lets you browse and view all of the files that you have stored there. The free 2GB edition is probably enough for just storing notes, but I also pay $99/year for the 50GB storage upgrade and keep all of my music, e-books, pictures, and documents in Dropbox. It’s a fantastic service and I highly recommend it. Evernote – I use Evernote mostly to organize information that I access on a fairly regular basis. For example, my Evernote account has a running grocery shopping list, recipes that my wife and I use a lot, and contact information for people I contact infrequently enough that I don’t want to keep them in my phone. I know some people that keep nearly everything in Evernote, but there’s something about it that I find a bit clunky, so I tend to use it sparingly. Google Tasks – One of my biggest paper wasting habits was keeping a running task-list next to my computer at work. Every morning I would sit down, look at my task list, cross off what was done and add new tasks that I thought of during my morning commute. This usually resulted in having to re-copy the task list onto a fresh sheet of paper when I was done. I still keep a running task list at my desk, but I’ve started using Google Tasks instead. This is a dead-simple web-based application for quickly adding, deleting, and organizing tasks in a simple checklist style. You can quickly move tasks up and down on the list (which I use for prioritizing), and even create sub-tasks for breaking down larger tasks into smaller pieces. Balsamiq Mockups – This is a simple and lightweight tool for creating drawings of user interfaces. It’s great for sketching out a new feature, brainstorm the layout of a interface, or even draw up a quick sequence diagram. I’m terrible at drawing, so Balsamiq Mockups not only lets me create sketches that other people can actually understand, but it’s also handy because you can upload a sketch to a common location for other team members to access. I can honestly say that using these tools (and having limited resources at home) have lead me to cut my paper usage down to virtually none. If I ever were to return to a traditional office workplace (hopefully never!) I’d try to employ as many of these applications and techniques as I could to keep paper usage low. I feel far less cluttered and far better organized now.

• Efficient solution for multiplayer space partioning?

  - by DevilWithin

  This question is a little tricky, but I will try to make it clear, Lets say I am building an online game, not in a mmo scale, but gladly supporting as many players as possible, in a authoritative server approach, and I want really big worlds with lots of AI simulated enemies. I am aware of a few strategies to save server's CPU by subdividing the space and not processing what doesn't need processing. I 've already split the world by regions, that will require loading times and small transitions, which i think is important to mantain the quality of gameplay when playing locally (alone or even with a couple of friends) because the players won't normally be in more than one or two regions. But even a region can become pretty big, and have a lot of NPC simulating at a time, how do I handle this without screwing the player's experience? Approaches like one server per region and alike are not in the table. I am mainly looking for data structures to hold hordes of enemies, and even peaceful NPC. To finalize the question, please note that vehicles exist, therefore its considerably fast to travel within a region, influencing the "when" to cull areas. Sorry for the confusing question, thanks

• Syslog/kernlog filling up with "did not claim interface N before use"

  - by Wayne Werner

  As I discovered when asking this question, it appears that demond_nscan is trying to use a device without claiming it. And it does it.... hundreds of time per second apparently. This makes kern.log and syslog huge (100GB ). In this particular case the problem is directly a result of some Lexmark drivers that were installed (found at /usr/local/lexmark/unix_scan_drivers/bin/demond_nscan). Here are a few things I know: The drivers are for an all-in-one printer/scanner device. There was a previous lexmark printer-only that was installed with CUPS This driver was the one for CUPS systems, and I think that it automatically added it to the list of printers in CUPS. The issue started spamming kern/syslog only after these drivers were installed, using the lexmark installers While googling around I found this thread that's not completely related, but it does mention that it might be happening when two drivers try to control the same device at the same time. How can I resolve this issue so that either I only have one driver, or get the driver to claim the device before usage?

• Lazy coding is fun

  - by Anthony Trudeau

  Every once in awhile I get the opportunity to write an application that is important enough to do, but not important enough to do the right way -- meaning standards, best practices, good architecture, et al.  I call it lazy coding.  The industry calls it RAD (rapid application development). I started on the conversion tool at the end of last week.  It will convert our legacy data to a completely new system which I'm working on piece by piece.  It will be used in the future, but only the new parts because it'll only be necessary to convert the individual pieces of the data once.  It was the perfect opportunity to just whip something together, but it was still functional unlike a prototype or proof of concept.  Although I would never write an application like this for a customer (internal or external) this methodology (if you can call it that) works great for something like this. I wouldn't be surprised if I get flamed for equating RAD to lazy coding or lacking standards, best practice, or good architecture.  Unfortunately, it fits in the current usage.  Although, it's possible to create a good, maintainable application using the RAD methodology, it's just too ripe for abuse and requires too much discipline for someone let alone a team to do right. Sometimes it's just fun to throw caution to the wind and start slamming code.

• Ubuntu 12.04.2 won't boot after bumblebee instalation

  - by Andrej

  First of all sorry for my English, it's not my first language. Here is what I have done: I had a working ubuntu 12.04 with all updates and working bumblebee, so I could do optirun command and battery life was better than without bumblebee. Than I decided to reinstall both my systems installed windows 7 and ubuntu. Reinstalled Windows 7 all working as expected, than on other partition installed ubuntu 12.04. All worked perfectly. Than I installed bumblebee according to the procedure written here https://wiki.ubuntu.com/Bumblebee same steps that I used before. But now after I install drivers and do all written in procedure and I reboot my notebook system won't boot, it is simply stuck at black screen after short showing of start screen. I reinstalled ubuntu many times already and tried everthing, but when I try install nvidia drivers it won't boot after shutting down notebook and only thing I can do is reinstalling system. I have Lenovo Thinkpad Edge E530 and processor: Intel® Core™ i5-3210M CPU and graphic cards are Intel HD 4000 and Nvidia geforce gt630m After clean install without bumblebee, terminal command lspci| grep VGA is showing: 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 0de9 (rev a1) Can you suggest a sollution?? Or at least some links to similar topics??

• How far to go with Domain Driven Design?

  - by synti

  I've read a little about domain driven design and the usage of a rich domain model, as described by Martin Fowler, and I've decided to put it in practice in a personal project, instead of using transaction scripts. Everything went fine until UI implementation started. The thing is some views will use rich components that are backed up by unusual models and, thus, I must transform the domain model into what is used by those components. And that transformation is specially "complex" in the view-to-domain portion, up to the point that some business logic is involved. Wich brings me to the questioning: where should I do these adaptations? So far I've got the following conclusions: Doing it in the presentation layer is good because, well, if that layer imposes restrictions in it's model, then it should be the one to handle them. But it's bad because there'll be some business leakage. If I do it on the services objects (controllers, actions, whatever), then it'd be good because there won't be any change to the domain API just because of presentation layer, but it's bad because then I'd have transaction scripts, wich is not the intended design. Finally, if I do it on the domain model, there'd be no leakage of business logic at all. But in the future I could expect an explosion of the API into a series of methods designed just to handle that view-model <- domain-model adaptation. I hope I could make myself clear on this.

• Practical Approaches to increasing Virtualization Density-Part 1

  - by Girish Venkat

  Happy New year everyone!. Let me kick start the year off by talking about Virtualization density.  What is it?The number of virtual servers that a physical server can support and it's increase from the prior physical infrastructure as a percentage. Why is it important?This is important because the density should be indicative of how well the server is getting consumed?So what is wrong ?Virtualization density fails to convey the "Real usage" of a server.  Most of the hypervisor based O/S Virtualization  evangelists take pride in the fact that they are now running a Virtual Server farm of X machines compared to a Physical server farm of Y (with Y less than X obviously). The real question is - has your utilization of the server really increased or not.  In an internal study that was conducted by one of the top financial institution - the utilization of servers only went up by 15% from 30 to 45. So, this really means that just by increasing virtualization density one will not be achieving the goal of using up the servers in their server farm better.  I will write about what the possible approaches are to increase virtualization density in the next entry.

• Web application stopped behaving normally after migration from Dedicated servers to Ec2 servers

  - by sunny

  Web application stopped behaving normally after migration from Dedicated servers to Ec2 servers Old Dedicated Server configuration systemtype: 32 bit operating system. RAM: 3.99 Gb Ram Processer : 1.86 GHZ New Servers in EC2 systemtype: 64 bit operating system. RAM: 3.99 Gb Ram Processer : 2.73 GHZ - 2.31 GHZ Everthing is working fine in our production server. But as we migrated our web application from old servers to new servers and transferred the entire network traffice to new servers.Site suddenly stopped behaving abnormally. Sometimes it's super fast Some times slow. sometimes normal some times super slow and sometimes no response This all above happens with a time interval or around 2 - 3 minutes. This went on happening 8 - 10 hours. Few differences in old and new servers are Old servers are using II6 and New servers are using IIS 7.5. We are using exactly the same code in the old and new servers. Even the ec2 servers are having higher CPU then older servers but still having lower. But not sure how this is happned. Please suggets your views...

• Final Man vs. Machine Round of Jeopardy Unfolds; Watson Dominates

  - by ETC

  The final round of IBM’s Watson against Ken Jenning and Brad Rutter ended last night with Watson coming out in a strong lead against its two human opponents. Read on to catch a video of the match and see just how quick Watson is on the draw. Watson tore through many of the answers, the little probability bar at the bottom of the screen denoting it was often 95%+ confident in its answers. Some of the more interesting stumbles were, like in the last matches, based on nuance. By far the biggest “What?” moment of the night, however, was when it answered the Daily Double question of “The New Yorker’s 1959 review of this said in its brevity and clarity, it is ‘unlike most such manuals, a book as well as a tool’”. Watson, inexplicably, answered “Dorothy Parker”. You can win them all, eh? Check out the video below to see Watson in action on its final day.

• How to start a s3ql script automatically on boot?

  - by ks78

  I've been experimenting with s3ql on Ubuntu 10.04, using it to mount Amazon S3 buckets. However, I'd really like it to mount them automatically. Does anyone know how to do that? I've been working on a script, which works when its run from from the commandline, but for some reason I can't get it to run automatically on boot. Does anyone have any ideas? Here's my script: #! /bin/sh # /etc/init.d/s3ql # ### BEGIN INIT INFO # Provides: s3ql # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Start daemon at boot time # Description: Enable service provided by daemon. ### END INIT INFO case "$1" in start) # Redirect stdout and stderr into the system log DIR=$(mktemp -d) mkfifo "$DIR/LOG_FIFO" logger -t s3ql -p local0.info < "$DIR/LOG_FIFO" & exec > "$DIR/LOG_FIFO" exec 2>&1 rm -rf "$DIR" modprobe fuse fsck.s3ql --batch s3://mybucket exec mount.s3ql --allow-other s3://mybucket /mnt/s3fs ;; stop) umount.s3ql /mnt/s3fs ;; *) echo "Usage: /etc/init.d/s3ql{start|stop}" exit 1 ;; esac exit 0

• Open source vs commercial game engines

  - by Vanangamudi

  How commercial game accomplsih stunnning graphics with smooth game play? I am a huge die hard fan and follower of GNU Stallman and his philosophies and other Libre people Cmon how wud I miss Linus. but I got to admit commercial games does excellent jobs. One such good example is Assasin's Creed from Ubisoft. It has good quality graphcis and plays smoothly in my Dual core CPU with Nvidia Geforce 8400ES. Rockstar GTA4 has awesome graphcis but it's slower than AC considering the graphics quality tradeoff. Age of Empires from Ensemble studios, does include Massive crowd AI simulation, yet it plays so smoothly with eyecandy graphics and very large weapon sets and different techtree elements on the other hand. Open source games like Glest, 0A.D(still in alpha :) are not so smooth even though they have very restricted abilities? Coming to question: how do game companies achieve such optmizations, or the open source community is not doing optimizations, or there are any propriarity technological elements that benefits only the companies exists huh?? e.g the OpenSubDiv from Pixar just released open to community?? something like that. and why it is hard to implement optimizations? are there any legal restrictions???

• IOS OpenGl transparency performance issue

  - by user346443

  I have built a game in Unity that uses OpenGL ES 1.1 for IOS. I have a nice constant frame rate of 30 until i place a semi transparent texture over the top on my entire scene. I expect the drop in frames is due to the blending overhead with sorting the frame buffer. On 4s and 3gs the frames stay at 30 but on the iPhone 4 the frame rate drops to 15-20. Probably due to the extra pixels in the retina compared to the 3gs and smaller cpu/gpu compared to the 4s. I would like to know if there is anything i can do to try and increase the frame rate when a transparent texture is rendered on top of the entire scene. Please not the the transparent texture overlay is a core part of the game and i can't disable anything else in the scene to speed things up. If its guaranteed to make a difference I guess I can switch to OpenGl ES 2.0 and write the shaders but i would prefer not to as i need to target older devices. I should add that the depth buffer is disabled and I'm blending using SrcAlpha One. Any advice would be highly appreciated. Cheers

• Lenovo Ideapad 205 and Ubuntu 12.04 LTS

  - by Oranges

  I just wanted to report one thing, because I know there are a lot of Ideapad S205 users out there, that had issues running Ubuntu on their Lenovo Ideapad S205 in the past. Lenovo Ideapad with Ubuntu 12.04 LTS: Everything works out of the box. I just installed it and everything, including the microphone, the webcam, the WLAN, the AMD E-350 CPU/GPU and the sound worked right away. In other words: Everything works. Even the AMD E-350 GPU works very well with the Open Source drivers and with the prop. drivers. The prop. drivers were automatically offered to me via Ubuntu itself. It works great. A long idea, written short: I love it. It's extremly stable and very fast. I am using the German version of the Idepad S205, combined with the 32bit version of Ubuntu. There is only one, single thing to keep in mind when installing Ubuntu on the S205: Plugin your USB/CD/DVD drive in the left USB-Port. I don't know why, but it only works with the USB-Port on the left side of the Netbook. This is only for installing Ubuntu. After it has been installed and updated successfully, all of the USB ports will work. Oranges - feedback on Lenovo S205 with Ubuntu 12.04 LTS.

On another computer it reported temperatures below 0 degrees centigrade, which was not possible, considering the environment temperature of ~22-24. Is this some known bug/issue? Should I try some Windows programs (like CPU-Z) and see they give similar results?

• SO-overflow induced passivity - how to cope?

  - by Ruben

  After not really working on my pet project for a while, I discovered Stackoverflow and upon perusing it more intensely I was quite amazed. I'm a bit of a perfectionist, so when I found eye-openers here highlighting many of the mistakes I made, I first wanted to fix everything. However, it's a pet project for a reason: I'm self-taught and I'm studying psychology, so programming skills can never become priority one (though it often helps, even in this field). Issues that stuck out were numerous security issues (e.g. CSRF-prevention and bcrypt eluded me) not object-oriented (at least the PHP part, the JS-part mostly is) no PHP framework used, so many of my DIY takes on commonly-tackled components (auth, ...) are either bad or inefficient really poor MySQL usage (no prepared statements, mysql extension, heard about setting proper indices two days ago) using mootools even though JQuery seems to be fashionable, so there's more probably always going to be better integration with services I'd like to use (like google visualization) So, my SO-induced frenzy turned into passivity. I can't do it all (soon) in the rather small amount of spare time I can spend on working on my project. I can leave some of the issues be in good conscience (speed stuff: an unfinished & unpublished project will never become popular, right?). No clear conscience without good security though and if I don't use a framework for auth and other complex stuff I'll regret having to do it myself. One obvious answer would probably be going open-source, but I think the project would need to become more impressive before others would commit to it. I can't afford to employ someone either. I do think the project deserves being worked on, though. How should I tackle it anyway? What's the best practice for little-practice people?
