• Is embedded programming closer to electrical engineering or software development?

  - by Jeremy Heiler

  I am being approached with a job for writing embedded C on micro controllers. At first I would have thought that embedding programming is to low on the software stack for me, but maybe I am thinking about it wrong. Normally I would have shrugged off an opportunity to write embedded code, as I don't consider myself an electrical engineer. Is this a bad assumption? Am I able to write interesting and useful software for embedded systems, or will I kick myself for dropping too low on the software stack? I went to school for computer science and really enjoyed writing a compiler, managing concurrent algorithms, designing data structures, and developing frameworks. However, I am currently employed as a Flex developer, which doesn't scream the interesting things I just described. (I currently deal with issues like: "this check box needs to be 4 pixels to the left" and "this date is formatted wrong".) I appreciate everyone's input. I know I have to make the decision for myself, I just would like some clarification on what it means to be a embedded programmer, and if it fits what I find to be interesting.

• How to move from Programmer to Project Lead

  - by DoctaStooge

  At my job, I'm currently a programmer, but in the next few weeks I'll be taking control my own project. I was wondering if anyone else here has been in the same situation, and if so, what advice you can offer to help me be able to better run my project. Experience in dealing with contractors would be greatly appreciated. A little more info: Project will have 3 people including myself, with extra people coming in when needing testing. The project has been programmed mainly by 2 people I would like to contribute to the programming as I like doing it and think I can add to the program, but am afraid of how the contractors will react. I don't want to create bad feelings which may harm the project. EDIT: Forgot to mention that I'll have to be picking up communications with customers to make sure their needs are met. Any advice on talking to customers cold would be greatly appreciated. EDIT 2: This is not a new project, I'm picking it up around version 6. Sorry that I didn't make it clear before.

• Building an intranet

  - by WernerCD

  I'm researching for a project I'm going to be doing at work on the side... I work for a small hospital and we recently upgraded all the browsers inside our intranet to IE8 (Goodbye 6 :). We have a small, obsolete intranet built by someone who isn't a web designer... functional enough, but annoying to maintain and really sparse. What I'm wanting to do... is use a good framework. I'm looking for suggestions... I'm looking for something Windows IIS based. I'd love windows authentication - with the ability to delegate sub-sections of the website to managers. Right now it's my job to add/update/delete anything from the site... I'd like something not complicated that can be delegated to non-technical people. Like... the Cafeteria Manager should be able to update the menu without putting a ticket into me. She'd log into her computer, open the intranet (which would use her windows log-on to identify her) and have elevated privileges to edit her section of the intranet. If I have to "extend" a good framework to get Windows Authentication, I'll do it... but I'd prefer it to be baked in. What are some good frameworks, tools and places to start? While this isn't a "Huge" project... it's going to be bigger than the basic stuff I've done before and I'd like a good place to start.

• Korea&rsquo;s Anti Abortion / Pro Life Movement

  - by Randy Walker

  The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

• why are transaction monitors on decline? or are they?

  - by mrkafk

  http://www.itjobswatch.co.uk/jobs/uk/cics.do http://www.itjobswatch.co.uk/jobs/uk/tuxedo.do Look at the demand for programmers (% of job ads that the keyword appears), first graph under the table. It seems like demand for CICS, Tuxedo has fallen from 2.5%/1% respectively to almost zero. To me, it seems bizarre: now we have more networked and internet enabled machines than ever before. And most of them are talking to some kind of database. So it would seem that use of products whose developers spent last 20-30 years working on distributing and coordinating and optimizing transactions should be on the rise. And it appears they're not. I can see a few causes but can't tell whether they are true: we forgot that concurrency and distribution are really hard, and redoing it all by ourselves, in Java, badly. Erlang killed them all. Projects nowadays have changed character, like most business software has already been built and we're all doing internet services, using stuff like Node.js, Erlang, Haskell. (I've used RabbitMQ which is written in Erlang, "but it was small specialized side project" kind of thing). BigData is the emphasis now and BigData doesn't need transactions very much (?). None of those explanations seem particularly convincing to me, which is why I'm looking for better one. Anyone?

• In which fields does quality of the software product matter as much as the completion time?

  - by Nav

  Someone told me that if the software product meets clients expectations, it is good quality. But I've worked with Interaction Designers (the same kind of people who made Gmail's interface and usability so cool!), and I've loved working with them because even though they came up with hundreds of changes in requirements, and emphasised on many many subtle details, when the software was complete, I could look at the product and say WOW! The current place I work, the only thing that matters is completing the project on time. As long as it works and as long as the client says it's ok, nobody bothers to improve it. I'm not talking about gold-plating, but I believe that for a programmer to enjoy his (well, maybe her too ;) ) job, they should be able to proudly say that "Hey, I made that software" and that comes only when the product is of good quality. Apart from your opinions on this, I'd also like to know which fields (Eg. Aerospace, Finance etc.) could I find companies (or you could mention the company name) where the quality of a product is as important as completing the project on time?

• What would be a good opensource software for graphing circles, circular regions, and regions bounded by curves and/or arcs?

  - by Michael Dykes

  Hullo all. I have just started s job with Chegg, and my 1st assignment has me writign solutions for Stewart's Essential Calculus. I am dealing with the chapter on multiple integration, and need a good open-source software that I can easily use to draw regions (domains) that would require multiple integrals: i.e. circular regions, portions of circles, regions bounded by curves and/or arcs, and at some point 3D pictures. In most of these cases, I am not working with an exact equation or perhaps need to draw the region bounded by r (radius) between 1 and 2, and the angle theta bounded between pi/4 and 3 pi/4. I am not too terribly familiar with programs like Corel Draw, but the documents I have from this company suggest Corel Draw. So I think I am looking for an open-source free program like Corel Draw or something similar. Any additional suggestions would also be appreciated. I know I can do most, if not all of this using TikZ, but the learning curve is a bit steep, and at the moment I an on a time constraint. Thanks.

• Do you feel bad when you have to learn new things?

  - by tactoth

  New thing is not always cool. I see many people say they are very bored by doing the similar things day after day. For me it's the opposite - I'm always learning something new. During the last one and a harf year, nearly every two months I need to do lots of researches on a totally new topic: RTMP, MP4, SIP, VNC, Smooth streaming, ..., I have to read lots of specifications, download tones of open source projects to understand concepts, and turn them into my runnable code. And it was so bad! My brain has never been very sure and very familiar with anything, and when it's close to be sure and familiar, it'll have to switch to next thing. I kind of envy people who build upper level applications because they can be very focusing, and their knowledge set includes most things their job requires. Everything is quite measurable, direct and straightforward. Have you ever had the similar feeling? I'm thinking of asking my boss to assign me some other piece of work so that I work like moving forward on a broad road instead of figuring out a way in the dark, I think it'll be more relaxing, any suggestion?

• Is "send us a page with code" a typical interview requirement?

  - by acm

  Recently I was asked to show "a page with code" for a job interview. Being mainly a back-end programmer, and that's the position I applied for, I first said to the person I was talking to exactly that: PHP is executed at the server and therefore not visible by just giving a "page". However, following their desire, I sent links to the pages I've worked on before. Obviously they couldn't see anything except for the HTML, CSS, JS... They said it was not enough, they could not see the PHP. Understanding that they probably just wanted to know my skills and/or interest I sent them my Stack Overflow profile. Among all my questions and answers, most of them with code, certainly the PHP is there. But it seems this is not what they wanted. Well, I don't have any code put together that I can simply publish for someone to see. And I would never do it for the code I have deployed, obviously. So my question is/are: What does "send us a page with code" mean? What should I send? Is this a typical interview requirement?

• Upgrading a hard disk – To repave or to migrate, that is the question

  - by guybarrette

  I recently changed my laptop hard disk from the stock 250GB 5400 drive to a 320GB 7200 drive.  And no, I didn’t bought a SSD drive because the cost is way too much right now.  At $70, my upgrade was a lot cheaper than a SSD drive.  Maybe next year. When changing a system main hard drive, one must ask himself: To repave or to migrate, that is the question.  I choose to migrate so I went to the Acronis Website to take a look at their product line.  They have a few products that could do the job.  One being Acronis Migrate Easy 7.0 and the other being Acronis True Image Home 2010.  Since True Image was just $10 more then Migrate Easy, I bought True Image. I inserted my new hard drive in a 2.5” USB enclosure, and started the migration process.  Once the data copied, I switched the drives.  The process went very smoothly and without hiccups.  Highly recommended. BTW, Acronis offers free trials so I guess that nothing can stop you from “testing” a migration  ;-) var addthis_pub="guybarrette";

• Simple C: How do I scan this information in properly?

  - by Doc

  OK this is a simple question but for some reason I just can't get it right. I have to scan from a file hundreds of lines of code and store it in a array (which I can normally do a ok job with) however At one point the code will specify a number that then corresponds to the next batch of chars ints and floats going into various arrays. As I know I am not describing this correctly here is a example. one line of the file I am reading will contain something close to this. 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom the problem I am having is This part here 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom The rest after this is Generally the exact same however at this point the number at the front descides all the values that are going in. I am almost completely lost on how to write a way that can scan this and store the data into arrays correctly

• How do you keep down your urge to learn many things [closed]

  - by devsundar

  One of the difficulties i have is to lower my urge to learn new things (Languages, tools, frameworks etc.). I know it's good to stay the bleeding edge, but at the same time i want to learn things properly. I really see that i need to strike a balance between staying bleeding edge and knowing things properly. For example: Before choosing Arch (Desktop), Ubuntu(Server) and Knoppix(Portable) -- depending on situation -- as favourite distributions. Virtually i have tried all popular linux distributions. You name any popular linux (Redhat, Ubuntu, Arch, Suse, Knoppix, Slax, Slackware) i have tried it for some time. In fact i have spent few years experimenting the operating systems. Before choosing Python, Javascript (nodejs). I have tried all the languages i cameacross Scala, Haskell, Erlang, Ruby, Python, Perl, Scheme. Same applies for database. All popular db RDBMS (Oracle, Mysql, Postgres, SQLite[Favourite] etc) and NoSQL (Mongo, Couch, Neo4j etc.). Advantages i see: We get a overall picture of the technologies/tools/languages. It's useful to select the right tool for the job. We develop a taste and choose the One we like. Disadvantages: I feel that i spend somuch time and see a need to strike a balance. In summary, for e.g. If i see a blog post in HackerNews about CofeeScript i will try it out irrespective of what i am currently learning (Say Haskell). I switch back to learning Haskell, then again i see DART i check it out. And this continues.. Effectively i take more time to learn Haskell, but learnt about other new stuff on the way. The quetion i have is how do you strike a balance between staying bleeding edge and learning properly.

• Downclock CPU reaching critical temperature

  - by Draga

  I have an HP tx1250 laptop. It always had serious overheating problems and although usually it runs fine I'm now running a continuous test for my dissertation, this brings the CPU temp close to the critical and from time to time the computer shutdown for reaching it (checked the log). I use to have the same problem on Win XP but I noticed Win Vista and 7 downclock the CPU when is necessary to cool it down so I was thinking if the same is possible on Ubuntu 12. The only program I've found that may do the job is computer temp ( http://computertemp.berlios.de/ ) but it doesn't seems to work under Ubuntu 12. The inside of the laptop is fairly clean, the thermal paste is quite recent, I'm keeping it lifted from the desk and judjung by the sound of the fan that's running fine as well. The pc in now running between 78 and 91 degrees C but about once a day it shut down for reaching 95. I need the results of the test it's running pretty soon so it's important that it runs non-stop. I've though to set the maximum clock of the CPU to slightly less the maximum but then these tests I'm running would take much more time. Thanks! PS: first and last HP laptop for me.

• How do I create the "Gnome-Desktop-Item-Edit" program's launch icon with root privileges and more?

  - by GanZ

  I personally dont prefer running commands in terminal to achieve a task and prefer apps to execute the job. Creating launcher for apps is one such command where I prefer the gnome-desktop-item-edit application for creating launchers. If the gnome package is installed, just searching "create launcher" opens the app. But, it doesnt serve any purpose, because for starters the application cannot create launchers for various apps without root permission and the location where the apps have to be created. Usually the launcher apps with root permission can be created at /usr/share/applications and without root permission at /.local/share/applications. I dont prefer the latter location as it is vulnerable to deletion. Hence, in order to create the launchers through gnome with root, everytime I am forced to open this through terminal using the below command! $ sudo gnome-desktop-item-edit ~/.local/share/applications --create-new I dont want to open terminal everytime I want to create an application launcher on unity! I am able to lock the "Create Launcher" App in the Launcher, but not with root privileges So I want to be able to create the "Create Launcher" app shortcut on unity with default root privileges and for the app to create the launchers at usr/share/applications by default! Please help! P.S. I dont have enough rep points to add screenshots to help with the question!

• Why does there seem to be a lot of fear in choosing the "wrong" language to learn?

  - by Shewbox

  Perhaps its just me, but as a current CS student I have already come across many questions on this site and elsewhere about not just "Which language should I use for x?" but also "Does anyone still use language Y?" My first CS class was taught in Scheme, which, if I'm not mistaken, isn't used widely (at least in comparison to languages like Java, PHP, Python, etc). Many of my classmates balked at the idea of having to learn a language they would never have to use again, but I don't quite understand where so much of this fear of learning less popular languages comes from. No, I may not use Scheme in any job I get, but I certainly don't regret having learned to use it (albeit in a very beginner, not very in-depth manner in that one semester). I am taking a search engines class this semester, which is done in Perl and again I am seeing classmates complaining about the language choice. I can understand having a favorite language and disliking others but why do some get worked up over learning it in the first place? Can you really learn the "wrong" language? Isn't learning something like Scheme or Haskell good mental exercise if nothing else, and useful at least to exposure to different ways of solving problems?

• Is it reasonable to null guard every single dereferenced pointer?

  - by evadeflow

  At a new job, I've been getting flagged in code reviews for code like this: PowerManager::PowerManager(IMsgSender* msgSender) : msgSender_(msgSender) { } void PowerManager::SignalShutdown() { msgSender_->sendMsg("shutdown()"); } I'm told that last method should read: void PowerManager::SignalShutdown() { if (msgSender_) { msgSender_->sendMsg("shutdown()"); } } i.e., I must put a NULL guard around the msgSender_ variable, even though it is a private data member. It's difficult for me to restrain myself from using expletives to describe how I feel about this piece of 'wisdom'. When I ask for an explanation, I get a litany of horror stories about how some junior programmer, some-year, got confused about how a class was supposed to work and accidentally deleted a member he shouldn't have (and set it to NULL afterwards, apparently), and things blew up in the field right after a product release, and we've "learned the hard way, trust us" that it's better to just NULL check everything. To me, this feels like cargo cult programming, plain and simple. A few well-meaning colleagues are earnestly trying to help me 'get it' and see how this will help me write more robust code, but... I can't help feeling like they're the ones who don't get it. Is it reasonable for a coding standard to require that every single pointer dereferenced in a function be checked for NULL first—even private data members? (Note: To give some context, we make a consumer electronics device, not an air traffic control system or some other 'failure-equals-people-die' product.) EDIT: In the above example, the msgSender_ collaborator isn't optional. If it's ever NULL, it indicates a bug. The only reason it is passed into the constructor is so PowerManager can be tested with a mock IMsgSender subclass.

• Open Source Highlight: namebench

  - by eddraper

  DNS is a big deal.  Even small incremental changes to improve its performance can yield significant value due to the vast quantity of look-ups required when using the internet.  Until now, It’s always been one of those things I had to kinda take on faith… was my ISP doing a good job?  Are those public DNS server really that much faster?  What about security and privacy concerns? Let me introduce you to namebench.  This is the kinda tool I really love – one that immediately delivers value and is almost over-the-top OCD in its attention to detail. Trust me, this tool is utterly ruthless in it’s quest for getting it right – you’re not left with a big question mark after it presents its data.  The results are conclusive and actionable.  Here’s what is does: It hunts down the fastest DNS servers from your desktop that it can find using thousands of requests.  No, it doesn’t pop up this little dialog in 10 seconds to give you some “off the cuff” answer from a handful of providers.  It takes the better part of 10-15 minutes to run.  When it finishes, it presents you with a veritable horn-o-plenty of data.  Mean response duration, response distribution, bad data,  no stone is left un-turned. Check it out.  You’ll dig it.

• Compensation advice on overseas contract with former employer [closed]

  - by user64248

  I work as a full time developer in the US. My previous employer from 3 years ago has sold a large startup project in Russia for next month, however their three and only senior developers have recently resigned. I still have somewhat intricate knowledge of the software to be installed since I was the original author, so my former employer, in somewhat of a panic, has asked if I can take two weeks vacation from my current job to fly to Russia and lead the startup. Logistically, I can do this and my current employer agreed without issue. Said former employer is very small and hasn't hired contractors before, and I haven't contracted either. The company simply asked my what my salary requirements are. I had, and still have, a great professional relationship with the owners. I feel like I'm doing this as a favor in a way. Payment is guaranteed, but I have no idea what I should bill for overseas work. If it matters, I was paid around 110k at the former employer. Just looking for some advice. There are many contracting salary threads here, but I feel that the overseas work throws a twist in things. Thank you!

• Do you do custom tests/work for a potential employer before the interview?

  - by Chuck Stephanski

  Every shop I've worked at we have followed what I thought was a standard hiring sequence: 1. solicit resumes 2. phone screen applicants we are interested in 3. in person interview 4. in some shops 2nd in person interview (just w/ CEO for example) Most places I apply to follow something along these lines. But some shops want to give me a test or ask me to build something after I send in my resume. They usually say "congratulations, you've made it to stage 2 of our hiring process!" But for all I know they are asking every applicant they get a resume from to do the same thing. This annoys me because it doesn't scale. If I'm applying for a lot of positions I can't spend all my time doing work that potentially can only land me one job. Plus there's no shared dedication to the process. If we do a 45 minute phone screen, that's 45 minutes the company commits to me and 45 minutes I commit to the company in hopes of a potential match. Do you guys have a policy regarding these sorts of things?

• Drive reporting incorrect free space

  - by Oli

  So I swapped my shiny SATA SSD for an even shinier PCI-E SSD. I run my core OS on the SSD because it's silly-fast. I did this on my old SSD so I created a new EXT4 partition and then just dded the data across (sorry I don't know the exact command I ran anymore) and after reinstalling grub, I booted onto the PCI-E SSD. At first glance everything had worked perfectly and things were running faster than ever. But then I noticed the free disk space on the new, larger drive: it was almost exactly the same as it was on the other disk... A disk that was half its size. So it looks as if I've copied the files across incorrectly and it's copied some of the filesystem metadata along with it. Tools like du and Disk Usage Analyzer come back with the correct figures. Things that look at the partition (and not the files) seem to think the drive is 120GB I've been using this drive for a week now so it's way out of sync with the old SSD so dumping the data and starting again isn't a job that fills me with joy but two questions: Is there a way to fix my filesystem so it knows what it's really on about? fsck e2fsck and badblocks all seem to be able to scan it without finding a problem with it. If I do plug my old SSD back in, copy the data off my PCI-E on to it and then copy it back onto a fresh filesystem (eg juggle the data around), what's the best way of doing that? I obviously want to keep all the permissions and softlinks where they are.

• Should this be written in C or php?

  - by user1867842

  This is my code; it speaks for itself on what I'm trying to do. <?php define("html","<html>"); define("htmlEnd","</html>"); etc... etc... ?> What I'm trying to do is make a wrapper for html's tags so they won't be needed anymore. But I can't get any of the attributes for html elements to be defined in PHP. This again speaks for itself; I don't know any other way of saying this. I guess how would I make another mark-up language like HTML without any tags but still keep everything about HTML is what I'm trying to say. My idea is for preventing XSS. For example, creating a special framework for the website itself that way there is no way any malicious attacker can guess because they know the HTML or PHP. I just don't want to make my website or something, and then my website gets hacked. Or if I make a website for someone and the website gets hacked. I am going to look like a unprofessional web developer. And what if I never get a job again.

So that was slightly unexpected in some aspects and I'm just thinking about what approach to take with this /updated So far I've been sifting through the code to understand what each part does, printed out copies of code and try to lookup APIs I'm not familiar with, and so I dunno how effective this process is -- I feel like it's gonna take some time -- and I dont want my new employers to feel like I'm not being productive. Anyone have some ideas or approaches for this kind of situation? I read some of the questions about learning new languages, but I'm curious to see if anyone's had experience with this with PERL.

• How can I better manage far-reaching changes in my code?

  - by neuviemeporte

  In my work (writing scientific software in C++), I often get asked by the people who use the software to get their work done to add some functionality or change the way things are done and organized right now. Most of the time this is just a matter of adding a new class or a function and applying some glue to do the job, but from time to time, a seemingly simple change turns out to have far-reaching consequences that require me to redesign a substantial amount of existing code, which takes a lot of time and effort, and is difficult to evaluate in terms of time required. I don't think it has as much to do with inter-dependence of modules, as with changing requirements (admittedly, on a smaller scale). To provide an example, I was thinking about the recently-added multi-user functionality in Android. I don't know whether they planned to introduce it from the very beginning, but assuming they didn't, it seems hard to predict all the areas that will be affected by the change (apps preferences, themes, need to store account info somehow, etc...?), even though the concept seems simple enough, and the code is well-organized. How do you deal with such situations? Do you just jump in to code and then sort out the cruft later like I do? Or do you do a detailed analysis beforehand of what will be affected, what needs to be updated and how, and what has to be rewritten? If so, what tools (if any) and approaches do you use?
