• php application deployment to redhat [closed]

  - by Subhash Dike

  I am a .net background person with most of the work with Windows environment and IIS etc. I have been given a task to deploy one php application on RedHat Linux box. All I have is the credentials and the server IP of that box. Can someone help about how to get started creating a new website on Apache 2.0 on redhat box and then putting php code over to that. I do not have physical access to that server as well. I know it's very basis question, but I am in dark for these things. Even if you can point me to some documentation that's fine or else at least the analogy with IIS should also help to certain extent.

• Search the internet for a term selected in a text editor/viewer

  - by cipricus

  It seems possible (as I learned from a comment to this question made by user55822) to use Artha in order to search a term on the Internet by using "keybinding". What the aforementioned user says is that "you could search mouse selection anywhere by using an app like Artha, or by keybinding sh -c 'firefox "http://translate.google.com/#en/fr/$(xclip -o)"' (example given translate english into french)" A lot of things are obscure for me here. I could use Artha or keybinding (as alternative), or both? How to do that in each case? and "The command I gave you will open google translate in Firefox with your mouse selection (text highlighted) as a query. Use sh -c 'firefox "https://www.google.com/search?q=$(xclip -o)"' if you want regular Google over Google translate. And obviously, that would work everywhere" I do not know what to do with that formula. What should I do exactly? How to use it? In what application?

• What's the normal way machine-learning algorithms are integrated into normal programs?

  - by Benjamin Pollack

  I'm currently taking a machine learning course for fun, and the course heavily focuses on Matlab/Octave to write the code. One thing mentioned in the course is that, while Matlab/Octave are great for prototyping, they're very rarely used for production algorithms. Instead, those algorithms are typically rewritten in C++/Python/etc., using appropriate libraries, before reaching customers. Fair enough; I get that. But here's my question: is that done for cultural reasons, for technical reasons, or because there is really no language that provides Matlab/Octave-like fluidity, but in a compiled form that can be linked from C/C++/$MainstreamLanguage? The game industry uses Lua for game logic because it's easy to embed, and vastly superior for expressing things like AI. Likewise, there are Prolog variants for rules-heavy applications, Scheme variants for compilers, and so on. If there's a matrix equivalent language, what is it? If there isn't, why is this field different?

• Making it myself vs. modifying someone else's code as a beginner

  - by JamesGold

  I just started getting into open source projects mainly for the learning experience. I've made a few tiny contributions to some small projects. Most of my time has been spent just reading over other people's code and trying to understand how it works. Often times I find myself frustrated by a lack of documentation and unit tests. There are also times where I think I can see a more intuitive solution to a problem, but implementing it would require large restructuring of code. I see all this and wonder to myself why I don't just start clean on the whole thing by myself and do things "the right way"? I'd also enjoy the experience of building it from scratch, as it would force me to learn skills that I might not learn by working on other people's code. On the other hand, working on other people's code is also a great experience because it requires me to understand and work with other people's code and collaborate with them. It's just harder, IMO. Thoughts?

• At what point is asynchronous reading of disk I/O more efficient than synchronous?

  - by blesh

  Assuming there is some bit of code that reads files for multiple consumers, and the files are of any arbitrary size: At what size does it become more efficient to read the file asynchronously? Or to put it another way, how small must a file be for it to be faster just to read it synchronously? I've noticed (and perhaps I'm incorrect) that when reading very small files, it takes longer to read them asynchronously than synchronously (in particular with .NET). I'm assuming this has to do with set up time for things like I/O Completion Ports, threads, etc. Is there any rule of thumb to help out here? Or is it dependent on the system and the environment?

• How to create a use case diagram for board game played on PC

  - by user970696

  I'm struggling with a task as I was given to practice UML and use cases. The problem is that I should model computer version of a board game so I am unsure about a few things. obviously it does not matter if you play against the PC or another player, the actions are the same. The game is simply like tic tac toe. E.g. Actor Player ---(Place a diamond)-----include----(Check for a row)---include--(Swap players) But the game is played on the PC, so is Check for row really a use case? And the same with Swap players? Because the system would do that. On the other hand, if it was not, how could I continue?

• Is it possible to map mouse coordinates to isometric tiles with this coordinate system?

  - by plukich

  I'm trying to implement mouse interaction in a 2D isometric game, but I'm not sure if it's possible given the coordinate system used for tile maps in the game. I've read some helpful things like this. However, this game's coordinate system is "jagged" (for lack of a better word), and looks like this: Is it even possible to map mouse coordinates to this successfully, since the y-axis can't be drawn on this tile-map as a straight line? I've thought about doing odd-y-value translations and even-y-value translations with two different matrices, but that only makes sense going from tile to screen.

  - by Jake Newkirk

  How do I change the color that the system displays just before the login screen is displayed? Here is the boot sequence on my machine in the order that things are displayed: The BIOS screen is flashed. A Black screen is displayed for a few seconds. My Plymouth splash screen is displayed. Purple screen is displayed for a few seconds (This is what I want to change). Finally, the login screen is displayed. Please let me know if you require any additional information while addressing this problem and as always, thank you for your time.

• Can't run TOR from terminal

  - by Thi G.

  So... I can't run TOR from my terminal. I have tried many different things, but I couldn't make it run. Once, it didn't stop to run when I wanted to. At my other attempt I also ended up failing because when it stopped to run I couldn't connect myself to the internet. I hope you can help me here guys. To be more specific, what I mean by "can't run from terminal" is that I can't hide my IP if I'm installing a program from terminal, for instance. Or if I'm running another program that is making a connection with the internet, my IP isn't being hidden. What I want is to make TOR work for all my programs. So my IP would be hidden in any connection with the internet.

• Why doesn't light continuous on my model?

  - by nosferat

  I created a basic textured cube model with Blender to practice modeling, and then I imported it into Unity. After I put up some lighting it looks pretty ugly. The light is not continuous on a row of textured cubes: What is more odd, the light on the blocks that makes up the floor is continuous. What am I doing wrong? UPDATE This is how it looks like without textures: https://dl.dropbox.com/u/45620018/without%20textures.PNG If I would not know that these are perfect cubes, I'd say there is a slight curve on surface. I also tried lightening the texture but it also didn't help: https://dl.dropbox.com/u/45620018/lighter%20texture.PNG I just simply exported the model from Blender and did not set up any normals or things like that. However I also did not do any special woth the floor brick model.

• What are good words for defining multiples?

  - by Scott Langham

  In databases you might take about one-to-many. This means there's one thing that maps to zero or more others. In this kind of style I'm looking for words that define min/max amounts of things. So far, I have: min max one 1 1 many 0 infinite optional 0 1 ??? 1 infinite Is there a single word that fits '???' to mean more than one? Do you have better alternatives for 'optional'? I'm wondering if there are any conventional names for those concepts?

• Search engine friendly, SEO blog software

  - by Steve

  Is there a comparison of the SEO capabilities of different blogging software/blogging plugins? I'd like things to be as optimised as possible. I have a basic grasp of SEO principles, probably 12-24 months old. I'm about to start a blog, after having a few previously. Also, I'm not up to speed on what pings are in the blogging world. What are they, and how do they work? I assume it is best to have blogging software that automatically pings.

• My own personal use of Oracle Linux

  - by wcoekaer

  It always is easier to explain something with examples... Many people still don't seem to understand some of the convenient things around using Oracle Linux and since I personally (surprise!) use it at home, let me give you an idea. I have quite a few servers at home and I also have 2 hosted servers with a hosted provider. The servers at home I use mostly to play with random Linux related things, or with Oracle VM or just try out various new Oracle products to learn more. I like the technology, it's like a hobby really. To be able to have a good installation experience and use an officially certified Linux distribution and not waste time trying to find the right libraries, I, of course, use Oracle Linux. Now, at least I can get a copy of Oracle Linux for free (even if I was not working for Oracle) and I can/could use that on as many servers at home (or at my company if I worked elsewhere) for testing, development and production. I just go to http://edelivery.oracle.com/linux and download the version(s) I want and off I go. Now, I also have the right (and not because I am an employee) to take those images and put them on my own server and give them to someone else, I in fact, just recently set up my own mirror on my own hosted server. I don't have to remove oracle-logos, I don't have to rebuild the ISO images, I don't have to recompile anything, I can just put the whole binary distribution on my own server without contract. Perfectly free to do so. Of course the source code of all of this is there, I have a copy of the UEK code at home, just cloned from https://oss.oracle.com/git/?p=linux-2.6-unbreakable.git. And as you can see, the entire changelog, checkins, merges from Linus's tree, complete overview of everything that got changed from kernel to kernel, from patch to patch, errata to errata. No obfuscating, no tar balls and spending time with diff, or go read bug reports to find out what changed (seems silly to me). Some of my servers are on the external network and I need to be current with security errata, but guess what, no problem, my servers are hooked up to http://public-yum.oracle.com which is open, free, and completely up to date, in a consistent, reliable way with any errata, security or bugfix. So I have nothing to worry about. Also, not because I am an employee. Anyone can. And, with this, I also can, and have, set up my own mirror site that hosts these RPMs. both binary and source rpms. Because I am free to get them and distribute them. I am quite capable of supporting my servers on my own, so I don't need to rely on the support organization so I don't need to have a support subscription :-). So I don't need to pay. Neither would you, at least not with Oracle Linux. Another cool thing. The hosted servers came (unfortunately) with Centos installed. While Centos works just fine as is, I tend to prefer to be current with my security errata(reliably) and I prefer to just maintain one yum repository instead of 2, I converted them over to Oracle Linux as well (in place) so they happily receive and use the exact same RPMs. Since Oracle Linux is exactly the same from a user/application point of view as RHEL, including files like /etc/redhat-release and no changes from .el. to .centos. I know I have nothing to worry about installing one of the RHEL applications. So, OL everywhere makes my life a lot easier and why not... Next! Since I run Oracle VM and I have -tons- of VM's on my machines, in some cases on my big WOPR box I have 15-20 VMs running. Well, no problem, OL is free and I don't have to worry about counting the number of VMs, whether it's 1, or 4, or more than 10 ... like some other alternatives started doing... and finally :) I like to try out new stuff, not 3 year old stuff. So with UEK2 as part of OL6 (and 6.3 in particular) I can play with a 3.0.x based kernel and it just installs and runs perfectly clean with OL6, so quite current stuff in an environment that I know works, no need to toy around with an unsupported pre-alpha upstream distribution with libraries and versions that are not compatible with production software (I have nothing against ubuntu or fedora or opensuse... just not what I can rely on or use for what I need, and I don't need a desktop). pretty compelling. I say... and again, it doesn't matter that I work for Oracle, if I was working elsewhere, or not at all, all of the above would still apply. Student, teacher, developer, whatever. contrast this with $349 for 2 sockets and oneguest and selfsupport per year to even just get the software bits.

• What is the general definition of something that can be included or excluded?

  - by gutch

  When an application presents a user with a list of items, it's pretty common that it permits the user to filter the items. Often a 'filter' feature is implemented as a set of include or exclude rules. For example: include all emails from [email protected], and exclude those emails without attachments I've seen this include/exclude pattern often; for example Maven and Google Analytics filter things this way. But now that I'm implementing something like this myself, I don't know what to call something that could be either included or excluded. In specific terms: If I have a database table of filter rules, each of which either includes or excludes matching items, what is an appropriate name of the field that stores include or exclude? When displaying a list of filters to a user, what is a good way to label the include or exclude value? (as a bonus, can anyone recommend a good implementation of this kind of filtering for inspiration?)

• What new games are available for Ubuntu in 2011?

  - by Oli

  I know there have been other questions like "What native games are available?" and they often have issues because they turn into a never-ending list of every game ever released for Linux. But I'd like to know what's coming out this year. Good answers can include: A game that's coming out in 2011 A Linux port being released for games that might be older (eg Trine) As much information and as many screenshots and links as possible Few old games unless they're doing a major update that changes the game very significantly. One game per answer, add as much information as possible and work with each other to build a catalogue of awesome things to look forward to this year.

• Is it better to concentrate on one or two research projects throughout undergrad?

  - by AruniRC

  Currently in the 4th semester of engineering in an Indian university. The thing is - is it better to do as many short-lived projects/research work on diverse topics of computer science or stick to one/two projects consistently throughout my undergraduate years? Case in point: currently working on an image-processing project that promises to carry on for a year or so (as per the prof). Does this seem like being over-specialized at too early a level? Although taking on too many things will spread me out thin and in all probability not end up getting any meaningful work done. Especially as I hope to apply for grad school in the US. Would really appreciate any views and suggestions on this.

• Simpler Times

  - by Simon Moon

  Does anyone else out there long for the simpler days where you needed to move a jumper in the jumper block to set your modem card to use IRQ7 so it would not conflict with the interrupts used by other boards in your PC and your modem card came with a 78 page manual telling you everything you would need to know to write your own driver for the board including a full schematic along with the board layout showing every chip, capacitor, and resistor?  Ahhhhh, the simplicity!I am wrestling with UserPnp issues for a USB software licensing dongle that is needed by some third party software in one of our production applications. Of course, every machine in production is virtual, so it could be anything in the chain of the software application library to the device driver running on the VM to the configuration of the simulated USB port to the implementation of the USB connection and transport in the virtual host to the physical electrical connections in the USB port on the hypervisor.If only there were the virtual analog to a set of needle-nose pliers to move a virtual jumper.Come to think of it, I always used to drop those damn things such that they would land in an irretrievable position under the motherboard anyway.

• SQL Bits VII

  - by Tomaz.tsql

  I was very happy to dive in into SQL Bits VII. Several interesting presentations, interesting concepts, advices and most of all interesting people. Some things actually disturb me. 1. the outlook of all presentations. I would recommend to have standardized outlook of all presentations for each of the presenter. Meaning, to have a general rules of PPT design (fonts, views, etc.), general diagrams, pictures that can be used by everyone (something like techEd introduced as well as SQL PASS). 2. access...(read more)

• Using implode, explode etc.. on one line vs separating them into multiple lines with meaningful variable names

  - by zhenka

  I see a lot of people coding in PHP being rather proud if they manage to write a complicated one line statement that does clever things. But what is the advantage? It is not only harder to keep in once head while writing, but makes code much less readable. In my opinion reading short statements, if well written, can be like reading an essay, while complicated one liners can potentially make me pause and think for much longer then it would take for the coder to simply separate them into meaningful units. Am I wrong in thinking this? How would you go about proving your point to another programmer regarding this?

• What is the career path for a software developer/ programmer? [closed]

  - by Lo Wai Lun

  I've been working as a programmer for a few months and I often study CCNA , CISSP for future. Besides simple coding I was working on specs, designing applications, and all those around-like things. My question is, I want to be a information / system security specialist. what's the career path I should be aiming for? Is it like working on code for the rest of my life? :) Restart my career from the network engineer ? Or do programmers make a good manager-position people ? I know it's very subjective. Thing is, lately I find myself much more into the designing/working on specs part of the development project then the coding itself. How do you see it? Would you like to go from development to information security? Would you like to work on a project with a manager that used to be a coder?

• Horizontal title bar shadow while in full screen

  - by Atcold

  While in full screen the horizontal shadow of the title bar (I am not too sure about its name) appears on top of everything. How can I get rid of it? It's quite distracting while coding in Guake mode and annoying while watching movies. In the picture I've setup Guake with some transparency (that's why you can see things underneath), but the shadow is on the top of everything while I am in fullscreen. This, as I have already said, happens to me both while I am watching movies or programming in fullscreen mode. This usually happens after awaking the laptop from hibernation. Now it looks like it has gone, but I am still wandering if someone knows something about it. And here back it is :[ I'm running Ubuntu 13.04

• Letting go of a project

  - by SkyOrg

  I've been the sole developer of a niche product for my company for nearly 6 years. I've grown quite attached to the project and I enjoy working on it. However, it was the decision of management to take the project out of my hands and move it under the wings of another team. Unfortunately, I'm having a hard time letting go of the project. I'm sad to see it leave my hands since I've put so much time into it and enjoyed working on it, but it also allows me to work on new things. I've even caught myself being a bit hostile to the other team, which is poor on my part. How can I convince myself to just let it go?
