  • Whats the easiest way to convert a long in C to a char*?

    - by dh82
    What is the clean way to do that in C? wchar_t* ltostr(long value) { int size = string_size_of_long(value); wchar_t *wchar_copy = malloc(value * sizeof(wchar_t)); swprintf(wchar_copy, size, L"%li", self); return wchar_copy; } The solutions I came up so far are all rather ugly, especially allocate_properly_size_whar_t uses double float base math.

  • Masters vs. PhD - long [closed]

    - by Sterling
    I'm 21 years old and a first year master's computer science student. Whether or not to continue with my PhD has been plaguing me for the past few months. I can't stop thinking about it and am extremely torn on the issue. I have read http://www.cs.unc.edu/~azuma/hitch4.html and many, many other masters vs phd articles on the web. Unfortunately, I have not yet come to a conclusion. I was hoping that I could post my ideas about the issue on here in hopes to 1) get some extra insight on the issue and 2) make sure that I am correct in my assumptions. Hopefully having people who have experience in the respective fields can tell me if I am wrong so I don't make my decision based on false ideas. Okay, to get this topic out of the way - money. Money isn't the most important thing to me, but it is still important. It's always been a goal of mine to make 6 figures, but I realize that will probably take me a long time with either path. According to most online salary calculating sites, the average starting salary for a software engineer is ~60-70k. The PhD program here is 5 years, so that's about 300k I am missing out on by not going into the workforce with a masters. I have only ever had ~1k at one time in my life so 300k is something I can't even really accurately imagine. I know that I wouldn't have at once obviously, but just to know I would be earning that is kinda crazy to me. I feel like I would be living quite comfortably by the time I'm 30 years old (but risk being too content too soon). I would definitely love to have at least a few years of my 20s to spend with that kind of money before I have a family to spend it all on. I haven't grown up very financially stable so it would be so nice to just spend some money…get a nice car, buy a new guitar or two, eat some good food, and just be financially comfortable. I have always felt like I deserved to make good money in my life, even as a kid growing up, and I just want to have it be a reality. I know that either path I take will make good money by the time I'm ~40-45 years old, but I guess I'm just sick of not making money and am getting impatient about it. However, a big idea pushing me towards a PhD is that I feel the masters path would give me a feeling of selling out if I have the capability to solve real questions in the computer science world. (pretty straight-forward - not much to elaborate on, but this is a big deal) Now onto other aspects of the decision. I originally got into computer science because of programming. I started in high school and knew very soon that it was what I wanted to do for a career. I feel like getting a masters and being a software engineer in the industry gives me much more time to program in my career. In research, I feel like I would spend more time reading, writing, trying to get grant money, etc than I would coding. A guy I work with in the lab just recently published a paper. He showed it to me and I was shocked by it. The first two pages was littered with equations and formulas. Then the next page or so was followed by more equations and formulas that he derived from the previous ones. That was his work - breaking down and creating all of these formulas for robotic arm movement. And whenever I read computer science papers, they all seem to follow this pattern. I always pictured myself coding all day long…not proving equations and things of that nature. I know that's only one part of computer science research, but that part bores me. A couple cons on each side - Phd - I don't really enjoy writing or feel like I'm that great at technical writing. Whenever I'm in groups to make something, I'm always the one who does the large majority of the work and then give it to my team members to write up a report. Presenting is different though - I don't mind presenting at all as long as I have a good grasp on what I am presenting. But writing papers seems like such a chore to me. And because of this, the "publish or perish" phrase really turns me off from research. Another bad thing - I feel like if I am doing research, most of it would be done alone. I work best in small groups. I like to have at least one person to bounce ideas off of when I am brainstorming. The idea of being a part of some small elite group to build things sounds ideal to me. So being able to work in small groups for the majority of my career is a definite plus. I don't feel like I can get this doing research. Masters - I read a lot online that most people come in as engineers and eventually move into management positions. As of now, I don't see myself wanting to be a part of management. Lets say my company wanted to make some new product or system - I would get much more pride, enjoyment, and overall satisfaction to say "I made this" rather than "I managed a group of people that made this." I want to be a big part of the development process. I want to make things. I think it would be great to be more specialized than other people. I would rather know everything about something than something about everything. I always have been that way - was a great pitcher during my baseball years, but not so good at everything else, great at certain classes in school, but not so good at others, etc. To think that my career would be the same way sounds okay to me. Getting a PhD would point me in this direction. It would be great to be some guy who is someone that people look towards and come to ask for help because of being such an important contributor to a very specific field, such as artificial neural networks or robotic haptic perception. From what I gather about the software industry, being specialized can be a very bad thing because of the speed of the new technology. I When it comes to being employed, I have pretty conservative views. I don't want to change companies every 5 years. Maybe this is something everyone wishes, but I would love to just be an important person in one company for 10+ (maybe 20-25+ if I'm lucky!) years if the working conditions were acceptable. I feel like that is more possible as a PhD though, being a professor or researcher. The more I read about people in the software industry, the more it seems like most software engineers bounce from company to company at rapid paces. Some even work like a hired gun from project to project which is NOT what I want AT ALL. But finding a place to make great and important software would be great if that actually happens in the real world. I'm a very competitive person. I thrive on competition. I don't really know why, but I have always been that way even as a kid growing up. Competition always gave me a reason to practice that little extra every night, always push my limits, etc. It seems to me like there is no competition in the research world. It seems like everyone is very relaxed as long as research is being conducted. The only competition is if someone is researching the same thing as you and its whoever can finish and publish first (but everyone seems to careful to check that circumstance). The only noticeable competition to me is just with yourself and your own discipline. I like the idea that in the industry, there is real competition between companies to put out the best product or be put out of business. I feel like this would constantly be pushing me to be better at what I do. One thing that is really pushing me towards a PhD is the lifetime of the things you make. I feel like if you make something truly innovative in the industry…just some really great new application or system…there is a shelf-life of about 5-10 years before someone just does it faster and more efficiently. But with research work, you could create an idea or algorithm that last decades. For instance, the A* search algorithm was described in 1968 and is still widely used today. That is amazing to me. In the words of Palahniuk, "The goal isn't to live forever, its to create something that will." Over anything, I just want to do something that matters. I want my work to help and progress society. Seriously, if I'm stuck programming GUIs for the next 40 years…I might shoot myself in the face. But then again, I hate the idea that less than 1% of the population will come into contact with my work and even less understand its importance. So if anything I have said is false then please inform me. If you think I come off as a masters or PhD, inform me. If you want to give me some extra insight or add on to any point I made, please do. Thank you so much to anyone for any help.

  • How to manage long running background threads and report progress with DDD

    - by Mr Happy
    Title says most of it. I have found surprising little information about this. I have a long running operation of which the user wants to see the progress (as in, item x of y processed). I also need to be able to pause and stop the operation. (Stopping doesn't rollback the items already processed.) The thing is, it's not that each item takes a long time to get processed, it's that that there are usually a lot of items. And what I've read about so far is that it's somewhat of an anti-pattern to put something like a queue in the DB. I currently don't have any messaging system in place, and I've never worked with one either. Another thing I read somewhere is that progress reporting is something that belongs in the application layer, but it didn't go into the details. So having said all this, what I have in mind is the following. User request with list of items enters the application layer. Application layer gets some information from the domain needed to process the items. Application layer passes the items and the information off to some domain service (should the implementation of this service belong in the infrastructure layer?) This service spins up a worker thread with callbacks for both progress reporting and pausing/stopping it. This worker thread will process each item in it's own UoW. This means the domain information from earlier needs to be stored in some DTO. Since nothing is really persisted, the service should be singleton and thread safe Whenever a user requests a progress report or wants to pause/stop the operation, the application layer will ask the service. Would this be a correct solution? Or am I at least on the right track with this? Especially the singleton and thread safe part makes the whole thing feel icky.

  • How long can you be out of the MS market before it affects your career [closed]

    - by dave
    I've been working with .Net since it first came out and have done my best to use the latest and greatest things from Redmond. That being said, I've been working for the past year in the Python/Unix/Web world. In order to keep myself relevant in the MS world, I've been working part-time on a WPF project but I do not know how much longer that work will continue. So my question is: If I were to move totally to the Unix/Python/Web world, how long could I stay there before it starts getting hard to get another MS job? I am trying not to burn bridges in my career as I've found MS jobs pay better and tend to be more plentiful. PS: I like my Python job since it is something new and I get to work from home. It has provided a different view on coding that I've found useful. EDIT: I was out of the MS market for 12 months before attempting to get another MS job. No-one said "Gee you've been gone a while" but I did get a conspicuous lack of responses to job applications. My feeling is that the head-hunters do not bother to look beyond your last job. In the end, I got employment via my own network rather than the pimps. So, to answer my question: "not long, especially if you trust your career to head hunters."

  • Short keyword-only HTML Title or Long Titles - to rank better

    - by user11221
    I would like to know if long html titles should be used for pages instead of google adwords keyword tool based short titles - for SEO / Ranking purposes? I feel that it is a mistake to use short html titles made up of 2-3 words strictly based on google adwords keyword tool. I have tried using short ones based on what the adwords keyword tool suggested, but that has served me no purpose as I cannot see my website pages anywhere in the search results. Please correct me, if wrong.

  • SQL Server-Determine which query is taking a long time to complete

    - by Neil Smith
    Cool little trick to determine which sql query which is taking a long time to execute, first while offending query is running from another machine do EXEC sp_who2 Locate the SPID responsible via Login, DBName and ProgramName columns, then do DBCC INPUTBUFFER (<SPID>) The offending query will be in the EventInfo column.  This is a great little time saver for me, before I found out about this I used to split my concatenated query script in to multiple sql files until I located the problem query

  • The Long Tail Keyword Phrase Phenomenon

    There's been much conversation and debate over whether to use short tail or long tail keyword phrases when working optimizing your articles and websites. I think a bit of both may be in order. Well let's first distinguish the difference and then we can talk about how we can apply them to our articles and/or website meta tags.

    I am using 11.10 on my laptop and have a following issue: If I single click on items in notification area (or indicators), like messaging menu, sound menu, calendar, a menu appears and disappears as soon as mouse button is released. I need to do a long press then move pointer to menu area to be able to select items in it. Any clues to fix it? P.S. This is a fresh install but my home folder (thus settings) were restored from previous Ubuntu installation.

  • Understanding Long Tail Keywords For SEO

    Long tail keywords are typically two or more words (a phrase) that you type into a search engine like Google when you are searching for a product, service, the answer to a question or any kind of research you might find necessary. And if you're not at the top of the search engines (preferably in one of the first 3 positions), your chances of making money online decrease substantially.

  • Tools for building long-running Javascript webapp

    - by FilipK
    Given my lack of familiarity with such tools, could you suggest what tools / frameworks would be suitable for developing a long-running JavaScript webapp? The webapp would display a constantly updating chart. The updates would come through WebSockets (preferably) or XmlHttpRequest. I know and have written JavaScript with JQuery, but for this task I assume something like backbone.js or ExtJS would be appropriate (or maybe not?).

    I am fixing all of the duplicate content on my ecommerce site with all orignal descriptions etc. How long does it take google to start ranking it again? I used to have a good ranking that converted quite a few sales, in the last week i have had next to nothing.

  • Is there something like a "long running offline transaction" for NHibernate or any other ORM?

    - by Vilx-
    In essence this is a followup of this question. I'm beginning to feel that I should give up the whole idea, but I'll give it one more shot. What I want is pretty much like a DB transaction. It should track my changes to the DB and then in the end allow me to either commit or rollback them. If I insert an object, I should get it back in my next (appropriate) SELECT query. If I delete it, future SELECT queries should not return it. Etc. But there is one catch - this transaction would be very long running. It would start when the user opened a form (I'm talking about Windows Forms here), and the commit/rollback would be when the user closed it(with OK/Cancel). So it could take anywhere between seconds and days. This requirement rules out a standard DB transaction because that would lock the tables/rows it touched, and other users wouldn't be able to use the system. Also the transaction should not commit ANY changes to the DB until it was really committed. So if one user makes some changes, others don't see them until OK button is hit. This prevents errors in case the computer crashes or is disconnected from the network. I'm quite OK if the solution puts constraints on my model (I'm using MSSQL 2008, btw). I can design the DB/code any way I like. I'm also fine with the idea that a commit could fail because someone already modified one of the objects my transaction touched. Is there anything like this? I looked at NHibernate.Burrow, but I'm not sure that that's the thing I want. Added: It's the very beginning of the project so I'm not tied to NHibernate. I started out with it but I can still change easily.

  • Ajax long polling (comet) + php on lighttpd v1.4.22 multiple instances problem.

    - by fibonacci
    Hi, I am new to this site, so I really hope I will provide all the necessary information regarding my question. I've been trying to create a "new message arrived notification" using long polling. Currently I am initiating the polling request by window.onLoad event of each page in my site. On the server side I have an infinite loop: while(1){ if(NewMessageArrived($current_user))break; sleep(10); } echo $newMessageCount; On the client side I have the following (simplified) ajax functions: poll_new_messages(){ xmlhttp=GetXmlHttpObject(); //... xmlhttp.onreadystatechange=got_new_message_count; //... xmlhttp.send(); } got_new_message_count(){ if (xmlhttp.readyState==4){ updateMessageCount(xmlhttp.responseText); //... poll_new_messages(); } } The problem is that with each page load, the above loop starts again. The result is multiple infinite loops for each user that eventually make my server hang. *The NewMessageArived() function queries MySQL DB for new unread messages. *At the beginning of the php script I run start_session() in order to obtain the $current_user value. I am currently the only user of this site so it is easy for me to debug this behavior by writing time() to a file inside this loop. What I see is that the file is being written more often than once in 10 seconds, but it starts only when I go from page to page. Please let me know if any additional information might help. Thank you.

  • How long would it take to learn Python?

    - by Josh
    Hi all I have decided to take the time out after work to learn Python. Python appeals to me because at work (Web and eLearning Company), I have to follow out very repetitive tasks like delete all these tags, rename all these tasks and even more advanced repetive tasks. Additionally it would be good for me to get an understanding of Python first because of its fairly easy to learn syntax. How long would it take to learn the basics and go through these tutorials on Python (+ the Python tutorial)? I will only be spending 1 hour or so on it in the afternoons. http://openbookproject.net/thinkcs/python/english2e/index.html I have told my piano teacher I would like to take a month of learning piano to do this would this be adequate time? After this I may choose to learn PHP, because that is mainly what we use for web development at work. Thanks Josh
