• What php programmer should know?

  - by emchinee

  I've dig the database here and didn't found any answer for my question. What is a standard for a php programmer to know? I mean, literally, what group of language functions, mechanisms, variables should person know to consider oneself a (good) php programmer? (I know 'being good' is beyond language syntax, still I'm considering syntax of plain php only) To give an example what I mean: functions to control http sessions, cookies functions to control connection with databases functions to control file handling functions to control xml etc.. I omit phrases like 'security' or 'patterns' or 'framework' intentionally as it applies to every programming language. Hope I made myself clear, any input appreciated :) Note: Michael J.V. is right claiming that databases are independent from language, so to put my question more precisely and emphasise differences: Practises or security, are some ideas to implement (there is no 'Pattern' object with 'Decorator()' method, is there?) while using databases means knowing a mysqli and a set of its methods.

• Earning extra cash as a programmer

  - by Anon

  I work as fulltime programmer and have a pretty well paid job for the country where I live, but I could do with a bit of extra cash at the moment (wife nagging about new kitchen etc.). I'd be interested in taking on small projects in my spare time. I'm not interested in writing malware or get rich quick schemes. I've checked out a few sites programmer freelance sites, but the projects all see to be very poorly paid or people that want malware creating (or both). Are there any good freelancing sites that I may have missed? Are there any other ways to find small freelance projects?

• What is the worst programmer habit?

  - by 0x4a6f4672

  Many people get into programming because programming is fun. At least in the beginning. After some time doing it professionally, programming is no longer fun, often just hard work. Sometimes we develop bad habits along the way to make it fun again. Some bad habits of programmers are well known, for example the "I fix that in a second" habit, the "reinvent the wheel" practice or the "all code except mine is crap" attitude (which often leads to "I will re-write the entire program from scratch" syndrome). There are things which a programmer should never do. What is the worst programmer habit?

• How to avoid being an API programmer only?

  - by anything

  I have almost six years of experience in java. I have developed many projects which used frameworks like Struts, Spring, Hibernate, JQuery , DWR, Ajax etc. I have used these technologies in almost all the projects I have worked on. Projects were very simple mostly with crud based apps. My everyday tasks involves creating few screens, writing queries, testing etc. After all these years I feel like I have turned into an API programmer who just uses these above mentioned frameworks which is not giving me any satisfaction of being a programmer. Is this normal or is it just me who is feeling like this?

• How do I read an arbitrary chunk from a PNG file?

  - by Mason Wheeler

  I've got some custom metadata to put into a PNG file. It's being saved through libpng, and it's not difficult to write out a custom chunk. I just call png_write_chunk with the name, length and data. But I can't see how to get the data back out again. I'd expect there to be a png_read_chunk function that takes a chunk name and returns a pointer to the data or something like that, but there's nothing like that in png.h. Does anyone know how to accomplish this?

• How can I write a Template.pm filter to generate PNG output from LaTeX source code?

  - by Sinan Ünür

  I am looking for a way of generating PNG images of equations from LATEX source code embedded in templates. For example, given: [% FILTER latex_display ] \begin{eqnarray*} \max && U(x,y) \\ \mathrm{s.t.} && p_x x + p_y y \leq I \\ && x \geq 0, y \geq 0 \end{eqnarray*} [% END %] I would like to get the output: <div class="latex display"><img src="equation.png" width="x" height="y"></div> which should ultimately display as: I am using ttree to generate documents offline. I know about Template::Plugin::Latex but that is geared towards producing actual documents out of LATEX templates. Any suggestions?

• Why do .png backgrounds appear black on iPhone device but not simulator?

  - by David Rea

  I started with a .tiff file and used GraphicConverter to change it to a .png and set a transparency color. Worked fine in the simulator but when I pushed to the device the transparency color became black. Tested with a .png I downloaded from the net and that worked fine, so it seems to only happen with some files. Thus I suspect it has something to do with the way GraphicConverter writes the .pngs, but I don't know enough about file formats to debug it. Any ideas/suggestions? Ideally I'd like to programatically treat all .pngs because my app allowed dynamic loading of arbitrary files, so I can't verify the transparency beforehand.

• Apache returning text/html on some png files

  - by Oren

  I have an Apache web server that has a sub folder for images. For some reason, a few of the .png files are returned as text/html and not as image/png. There is nothing indicating a permission problem and the files return with code 200 and with full size. I made sure that image/png is set and even tried forcing it with .htaccess Any idea where to look next? Edit: looks like an .htaccess configuration problem on a parent directory.

• Math questions at a programmer interview?

  - by anon

  So I went to an interview at Samsung here in Dallas, Texas. The way the recruiter described the job, he didn't make it sound like it was too math-oriented. The job basically involved graphics programming and C++. Yes, math is implied in graphics programming, especially shaders, but I still wasn't expecting this... The whole interview lasted about an hour and a half and they asked me nothing but math-related questions. They didn't ask me a single programming question, which I found odd. About all they did was ask me how to write certain math routines as a C++ function, but that's about it. What about programming philosophy questions? Design patterns? Code-correctness? Constness? Exception safety? Thread safety? There are a zillion topics that they could have covered. But they didn't. The main concern I have is that they didn't ask any programming questions. This basically implies to me that any programmer who is good at math can get a job here, but they might put out terrible code. Of course, I think I bombed the interview because I haven't used any sort of linear algebra in about a year and I forget math easily if I haven't used it in practice for a while. Are any of my other fellow programmers out there this way? I'm a game programmer too, so this seems especially odd. The more I learn, the more old knowledge that gets "popped" out of my "stack" (memory). My question is: Does this interview seem suspicious? Is this a typical interview that large corporations have? During the interview they told me that Google's interview process is similar. They have multiple, consecutive interviews where the math problems get more advanced.

• What should every programmer know about web development?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web application before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

• Woman Is the World's First Computer Programmer? [closed]

  - by Sveta Bondarenko

  This week, on 10th December, we celebrate the 197th birth anniversary of Ada Lovelace, often considered as the world's first computer programmer. Ada became famous not only as a daughter of romantic poet Lord Byron but also as an outstanding 19th century mathematician. Her works on analytical engine are recognized as the first algorithm intended to be processed by a machine. Women always played a crucial role in the computer science evolution, but unfortunately, they are considered to be not so good at programming and engineering as men. Even though the fair sex makes up a growing portion of computer and Internet users, there is still a large gender gap in the field of Computer Science. But all is not lost! According to the study women's enrollment in the computer science raised from 7 percent in 1995 to 42 percent in 2000. And it is still increasing. Soon women will take a well-deserved position among the world's top computer programmers. After all, a number of notable female computer pioneers such as Ada Lovelace, Grace Hopper, and Anita Borg have proven that women make great computer scientists. But will women make great contributions to the modern technologies industry? Or successful and famous female computer programmer is just a pipe dream?

• Ways to break the "Syndrome of the perfect programmer"

  - by Rushino

  I am probably not the only one that feel that way. But I have what I tend to call "The syndrome of the perfect programmer" which many might say is the same as being perfectionist but in this case it's in the domain of programming. However, the domain of programming is a bit problematic for such a syndrome. Have you ever felt that when you are programming you're not confident or never confident enought that your code is clean and good code that follows most of the best practices ? There so many rules to follow that I feel like being overwhelmed somehow. Not that I don't like to follow the rules of course I am a programmer and I love programming, I see this as an art and I must follow the rules. But I love it too, I mean I want and I love to follow the rules in order to have a good feeling of what im doing is going the right way.. but I only wish I could have everything a bit more in "control" regarding best practices and good code. Maybe it's a lack of organization? Maybe it's a lack of experience? Maybe a lack of practice? Maybe it's a lack of something else someone could point out? Is there any way to get rid of that syndrome somehow ?

• Thinking skills to be a good programmer

  - by Paul

  I have been programming for last 15 years with non-CS degree. Main reason I got into programming was that I liked to learn new things and apply them to my work. And I was able to find and fix programming errors and their causes faster than others. But I never find myself a a guru or an expert, maybe due to my non-CS major. And when I saw great programmers, I observed they are very good, much better than me of course, at solving problems. One skill I found good in my mid-career is thinking of requirements and tasks in a reverse order and in abstract. In that way, I can see what is really required for me to do without detail and can quickly find parts of solution that already exist. So I wonder if there are other thinking skills to be a good programmer. I've followed Q&As below and actually read some of books recommended there. But I couldn't really pickup good methods directly applicable for my programming work. What non-programming books should a programmer read to help develop programming/thinking skills? Skills and habits to develop to be good at programming (I'm a newbie)

• Attributes of an Ethical Programmer?

  - by ahmed

  Software that we write has ramifications in the real world. If not, it wouldn't be very useful. Thus, it has the potential to sweep across the world faster than a deadly manmade virus or to affect society every bit as much as genetic manipulation. Maybe we can't see how right now, but in the future our code will have ever-greater potential for harm or good. Of course, there's the issue of hacking. That's clearly a crime. Or is it that clear? Isn't hacking acceptable for our government in the event of national security? What about for other governments? Cases of life-and-death emergency? Tracking down deadbeat parents? Screening the genetic profile of job candidates? Where is the line drawn? Who decides? Do programmers have responsibility for how their code is used? What if a programmer writes code to pry into confidential information or copy-protected material? Does he bear responsibility along with the person who used the program? What about a programmer who knowingly or unknowingly writes code to "fix the books?" Should he be liable?

• Lead Programmer definition clarification

  - by Junaid

  I am working on PHP and MySQL based web application for more than 5 years now. I started my career from Intern - Jr Developer - Software Developer - Sr. Software Engineer [Team Lead] that's what I am nowadays. I was looking at the link at Wikipedia regarding who is a lead programmer. The link states the following: A lead programmer is a software engineer in charge of one or more software projects. Alternative titles include Development Lead, Technical Lead, Senior Software Engineer, Software Design Engineer Lead (SDE Lead), Software Manager, or Senior Applications Developer. When primarily contributing in a high-level enterprise software design role, the title Software Architect (or similar) is often used. All of these titles can have different meanings depending on the context. My current job responsibilities are more or less like a Development Lead and to some extent near Software Architect because I usually design the core structure of new products and managing 2-3 project simultaneously and in the meantime involved in assisting other teams regarding the structural design of their projects, I am usually on call with clients along with project managers, I code most of the time when my team stuck somewhere / workload / integrating some third party API and etc. Primary reason of this writing is to know if I qualify for a Development Lead Title? in accordance with my above mentioned job descriptions?

• Need Help Hiring a Perfectionist Programmer [closed]

  - by Bryan Hadaway

  I understand my question may be in the gray area, but I'm not able to use the Meta to ask if this question is appropriate or not so I'll simply have to risk it. My project is complete in the sense that it's a fully functional, ready to go 1.0 version. However, that's not good enough for my standards. My expertise is in HTML/CSS, not jQuery and PHP. I'm looking for someone to refine every character of my code for quality, speed, security and compatibility. I want everything to be as bug free as possible for launch. So I need an expert programmer who's a perfectionist in their coding who cares about the quality of their work (not just making it work) to review and refine my code. I'm sure I can't outright post the project's details and hope for interested parties to contact me as that wouldn't be beneficial to the community so instead I'm looking for advice from programmers about where some of best places to hire quality programmers are and the best strategies to hire the right programmer. In other words, screening applicants off of craigslist isn't going to cut it for this project. Thanks

• An entry-level programmer's best option [on hold]

  - by user134409

  I am facing a puzzle and I am not sure the best way to make a decision. In my spare time besides playing video games I got around to develop some games, nothing fancy, just small projects to get a better grasp at programming. After I finished college and got my BA in Computer Science, I got a job as web developer at a small firm. The next few months were very stressful as I had no previous experience and tried my best to make up for it. But after 6 months my boss told me I was inefficient and not very independent and let me go. To my credit, the help from the senior was very limited, I did learn a lot but I have learned by myself. For example they told me to do a UI in BackboneJS and I took me a while but I got it working (even if it was poorly designed). But I managed to do it all by myself because my senior was very busy and he did not have time even for my questions. Now I have found a new job again in web development but I am very afraid of what is going to happen next. I am afraid because I don't want to take the job and then be fired again after a couple of months, I get the feeling that this will be very bad on my CV, job hopping is like a red flag. They want to hire me but I am aware that they are working with new technologies and maybe I will end up not coping with it. So the question is: Should a entry-level programmer be better off with a starting job in QA, testing and work his way from there? I did learn allot from my first job but it was a moral blow when they decided to fire me. I do have a low self-esteem and I know my skills as a programmer are not that great. But I like programming and want to get better and I want to have a long career in it so that basically my pickle. Thank you in advance for the answers.

• How to get pngcrush to overwrite original files?

  - by DisgruntledGoat

  I've read through man pngcrush and it seems that there is no way to crush a PNG file and save it over the original. I want to compress several folders worth of PNGs so it would be useful to do it all with one command! Currently I am doing pngcrush -q -d . *.png then manually cut-pasting the files from the tmp directory to the original folder. So I guess using mv might be the best way to go? Any better ideas?

• What's the best way to install the GD graphics library for Nagios?

  - by user1196

  While trying to install Nagios 3.2.3, I ran their ./configure script and got these errors: checking for main in -liconv... no checking for gdImagePng in -lgd (order 1)... no checking for gdImagePng in -lgd (order 2)... no checking for gdImagePng in -lgd (order 3)... no checking for gdImagePng in -lgd (order 4)... no *** GD, PNG, and/or JPEG libraries could not be located... ********* Boutell's GD library is required to compile the statusmap, trends and histogram CGIs. Get it from http://www.boutell.com/gd/, compile it, and use the --with-gd-lib and --with-gd-inc arguments to specify the locations of the GD library and include files. NOTE: In addition to the gd-devel library, you'll also need to make sure you have the png-devel and jpeg-devel libraries installed on your system. NOTE: After you install the necessary libraries on your system: 1. Make sure /etc/ld.so.conf has an entry for the directory in which the GD, PNG, and JPEG libraries are installed. 2. Run 'ldconfig' to update the run-time linker options. 3. Run 'make clean' in the Nagios distribution to clean out any old references to your previous compile. 4. Rerun the configure script. NOTE: If you can't get the configure script to recognize the GD libs on your system, get over it and move on to other things. The CGIs that use the GD libs are just a small part of the entire Nagios package. Get everything else working first and then revisit the problem. Make sure to check the nagios-users mailing list archives for possible solutions to GD library problems when you resume your troubleshooting. ******************************************************************** Which package do I want? libgd2-xpm-dev? libgd2-noxpm-dev? php5-gd? I'm not looking to do any image processing myself - I just want to get Nagios working.
