  • Personal Software Process (PSP1)

    - by gentoo_drummer
    I'm trying to figure out an exercise but it doesn't really makes to much sense.. I'm not asking someone to provide the solution. just to try and analyse what needs to be done in order to solve this. I'm trying to understand which PSP 1.0 1.1 process I should use. PROBE? Or something else? I would greatly appreciate some help on this one from someone that has experience with the Personal Software Process Methodology.. Here is the question. For the reference case (“code1.c”), the following s/w metrics are provided: man-hours spent in implementation phase (per-module): 2,7 mh/file man-hours spent in testing phase (per-module): 4,3 mh/file estimated number of bugs remaining (per-module): 0,3 errors/function, 4 errors/module (remaining) Based on the corresponding values provided for the reference case, each of the following tasks focus on some s/w metrics to be estimated for the test case (“code2.c”): [25 marks] (estimated) man-hours required in implementation phase (per-module) [8 marks] (estimated) man-hours required in testing phase (per-module) [8 marks] (estimated) number of bugs remaining at the end of testing phase (per-module) [9 marks] Tasks 4 through 6 should use the data provided for the reference case within the context of Personal Software Process level-1 (PSP-1), using them as a single-point historic data log. Specifically, the same s/w metrics are to be estimated for the test case (“code2.c”), using PSP as the basic estimation model. In order to perform the above listed tasks, students are advised to consider all phases of the PSP software development process, especially at levels PSP0 and PSP1. Both cases are to be treated as separate case-studies in the context of classic s/w development.

  • Contract Work - Lessons Learned

    - by samerpaul
    I thought I would write a post of a different nature today, but still relevant to the tech world. I do a lot of contract jobs myself and really enjoy it. It's nice to keep jumping from project to project, and not having to go to an office or keep regular hours, etc. I really enjoy it. I have learned a lot in the past few years of doing it (both from experience and from help given to me from others, and the internet) so I thought I'd share some of that knowledge/experience today.So here's my own personal "lesson's learned" that hopefully will help you if you find yourself doing contract work:Should I take the job?Ok, so this is the first step. Assuming you were given sufficient information about what they want, then you should really think about what you're capable of doing and whether or not you should take this job. Personally, my rule is, if I know it's possible, I'll say yes, even if I don't yet know how to do it. That's because the internet is such a great help, it would be rare to run into an issue that you can't figure out with some help. So if your clients are asking for something that you don't yet know how to program, but you know you can do it on the platform then go for it. How else are you going to learn?Use this rule with some limitation, however. If you're really lacking the expertise or foundation in something, then unless you have tons of time to complete the project, then I wouldn't say yes. For example, I haven't personally done any 3d/openGL programming yet so I wouldn't say yes to a project that extensively uses it. OK, so I want the job, but how much do I charge?This part can be tricky. There is no set formula really, but I have some tips for pricing that will hopefully give you a better idea on how to confidently ask your price and have them accept. Here are some personal guidelinesHow much time do you have to complete the project? If it's shorter than average, then charge more. You can even make a subtle note about this (or not so subtle if they still don't get it.) If it seems too short of a time (i.e. near impossible to complete), be sure to say that. It looks bad to promise a time that you can't keep--and it makes it less likely for them to return to you for work.Your Hourly rate: How long have you been working in that language? Do you have existing projects to back you up? Or previous contacts that can vouch for your work? Are there very few people with your particular skill set? All of these things will lend themselves to setting an hourly rate. I'd also try out a quick google search of what your line of work is, to see what the industry standard is at that point in time.I wouldn't price too low, because you want to make your time worth it. You also want them to feel like they're paying for quality work (assuming you can deliver it :) ). Finally, think about your client. If it's a small business, then don't price it too high if you want the job. If it's an enterprise (like a Fortune company), then don't be afraid to price higher. They have the budget for it.Fixed price: If they want a fixed price project, then you need to think about how many hours it will take you to complete it and multiply it by the hourly rate you set for yourself. Then, honestly, I would add 10-20% on top of that. Why? Because nothing ever works exactly how you want it to. There are lots of times that something "trivial" is way harder than it should be, or something that "should work" doesn't for hours and it eats away at your hourly rate. I can't count the number of times I encountered a logical bug that took away an entire's day work because debuggers don't help in those cases. By adding that padding in, it's still OK to have those days where you don't get as much done as you want. And another useful tip: Depending on your client, and the scope, you most likely want to set that you both sign off on a specification sheet before doing any work, and that any changes will result in a re-evaulation of the price. This is to help protect you from being handed a huge new addition to the project half-way in, without any extra payment.Scope of project: Finally, is it a huge project? Is it really small/fast? This affects how much your client will be willing to pay. If it sounds big, they will be willing to pay more for it. If it seems really small, then you won't be able to get away with a large asking price (as easily).Ok, I priced it, now what?So now that you have the price, you want to make sure it feels justified to your client. I never set a price before I can really think about everything. For example, if you're still in your introduction phase, and they want a price, don't give one! Just comment that you will send them a proposal sheet with all the features outlined, and a price for everything. You don't want to shout out a low number and then deliver something that is way higher. You also don't want to shock them with a big number before they feel like they are getting a great product.Make up a proposal document in a word editor. Personally, I leave the price till the very end. Why? Because by the time they reach the end, you've already discussed all the great features you plan to implement, and how it's the best product they'll ever use, etc etc...so your price comes off as a steal! If you hit them up front with a price, they will read through the document with a negative bias. Think about those commercials on TV. They always go on about their product, then at the end, ask "What would you pay for something like this? $100? $50? How about $20!!". This is not by accident.Scenario: I finished the job way earlier than expectedYou have two options then. You can either polish the hell out of the application, and even throw in a few bonus features (assuming they are in-line with the customer's needs) or you can sit and wait on it until you near your deadline. Why don't you want to turn it in too early? Because you should treat that extra time as a surplus. If you said it is going to take you 3 weeks, and it took you only 1, you have a surplus of 2 weeks. I personally don't want to let them know that I can do a 3 week project in 1 week. Why not? Because that may not always be the case! I may later have a 3 week project that takes all 3 weeks, but if I set a precedent of delivering super early, then the pressure is on for that longer project. It also makes it harder to quote longer times if you keep delivering too early.Feel free to deliver early, but again, don't do it too early. They may also wonder why they paid you for 3 weeks of work if you're done in 1. They may further wonder if the product sucks, or what is wrong with it, if it's done so early, etc.I would just polish the application. Everyone loves polish in their applications. The smallest details are what make an application go from "functional" to "fantastic". And since you are still delivering on time, then they are still going to be very happy with you.Scenario: It's taking way too long to finish this, and the deadline is nearing/here!So this is not a fun scenario to be in, but it'll happen. Sometimes the scope of the project gets out of hand. The best policy here is OPENNESS/HONESTY. Tell them that the project is taking longer than expected, and give a reasonable time for when you think you'll have it done. I typically explain it in a way that makes it sound like it isn't something that I did wrong, but it's just something about the nature of the project. This really goes for any scenario, to be honest. Just continue to stay open and communicative about your progress. This doesn't mean that you should email them every five minutes (unless they want you to), but it does mean that maybe every few days or once a week, give them an update on where you're at, and what's next. They'll be happy to know they are paying for progress, and it'll make it easier to ask for an extension when something goes wrong, because they know that you've been working on it all along.Final tips and thoughts:In general, contract work is really fun and rewarding. It's nice to learn new things all the time, as mandated by the project ,and to challenge yourself to do things you may not have done before. The key is to build a great relationship with your clients for future work, and for recommendations. I am always very honest with them and I never promise something I can't deliver. Again, under promise, over deliver!I hope this has proved helpful!Cheers,samerpaul

  • How do I make money from my FOSS while staying anonymous?

    - by user21007
    Let's say that: You have created a FOSS project that other people find useful, perhaps useful enough to donate to or pay for modifications to be done. It is a perfectly legitimate and innocuous software project. It has nothing to do with cryptography as munitions, p2p music, or anything likely to lead to a search warrant or being sued. You want your involvement to stay anonymous or pseudonymous. You would like to receive some money for your efforts, if people are willing. Is that possible, and if so, how could it be done? When I talk about anonymity, I realize that it is necessary to define the extent. I am not talking about Wikileaks style 20 layers of proxies worth of anonymity. I would expect a 3 letter agency to be able to identify the person easily. What is wanted is shielding from commercial competitors or random people, who would not be expected to be able to get the financial intermediary to divulge your details just by asking for them. Why would you want to stay anonymous? I can think of several valid reasons, maybe you operate a stealth mode startup and don't want to give your competitors clues as to the technology you are using. Maybe it is a project that has nothing to do with your daily job, is not developed there, but the company you work for has an unfair (and possibly unenforceable) policy stating that any coding you do is owned by them. Maybe you just value your privacy. For what it's worth, you intend to pay the relevant taxes in your country on any donations.

Two KM articles reflect Oracles policy towards the use of VMware: 249212.1 and 475484.1 . The bottom line is: “you may use it at your own risk, but Oracle does not recommend it”. So far we have seen few problems with the use of VMware (other than performance and the usual limitations) but Oracle does not certify its software for the use in VMware (and specifically for RAC Software actively refuses any support) and any issue that may occur will be fixed for the native OS only. It is on the customer to prove that the issue is NOT due to VMware in case that an issue is encountered.

  • Weekly Cloud Roundup 2012-15

    - by Alan Smith
    Filtering the informative, insightful and quirky from the fire hose of cloud-based hype. Irving Wladawsky-Berger provides some great insight into The Complex Transition to the Cloud, sharing his views on the slow adoption of cloud computing in organizations. “…a prediction by the research firm Gartner that while cloud computing will continue to grow at almost 20 percent a year, it will account for less than 5 percent of totally IT spending in 2015.” With a more positive mindset, Balaji Viswanathan highlights 7 Salient Trends and Directions in Cloud Computing that could be shaping the industry over the next few years. Cloud computing also looks to save energy “A small business with 100 users that moved the Microsoft applications to the cloud could cut energy use and carbon emissions by 90%. Large organizations with 10,000 users saw a 30% reduction.” More on that story here. The expansion of Windows Azure has been in the news with the announcement of “East US” and “West US” datacenters; this was covered by Visual Studio Magazine and Mary-Jo, and according to thenextweb.com Microsoft are also building $112 million data center in Wyoming. The cloud price war is still in full swing with Joe Panettieri discussing the pricing of Windows Azure and Office 365 and asking How Low Can It Go?

  • Lubuntu: How do I arrange windows with keyboard shortcuts?

    - by iveand
    I have been testing with Lubuntu and have found it really pleasant. However, I cannot find an answer for one essential (for me) feature: being able to arrange windows with keyboard shortcuts. In Ubuntu this is done with the "Grid" plugin in "compizconfig-settings-manager". Unity uses this as well for window arranging. I am not interested in the "drag to the left to take up 1/2 the screen", but rather just the "hit some key combo" to put the active window to the left 1/2 of the screen, for example. I found this entry in "askubuntu" asking a very similar question: Is there a way to make Openbox behave like the Compiz Grid plugin? But it seems the "answer to this question", namely pyTile (http://sourceforge.net/projects/pytile/), doesn't do what I would like it to do. I don't want to tile all current windows, I want to resize one window at a time as I specify (left, right, top, center, bottom, 1/2, 2/3, 1/3, etc.). And I would prefer to do so with the keyboard. I think it possible to install compiz in Lubuntu, but this seems like "overkill" for this one feature (Grid keyboard shortcuts). Any help out there? It would REALLY MAKE MY DAY!!!

    I have always copy/paste this below code as a template for meta tags on project, but I think they are not effective as they could possible be. So, I need to know if there is anyway I can improve it. suppose I have a site called coop.com for a company called Coopm and we do import and export as a business in France. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <meta name="rpbots" content="index, follow" /> <meta name="description" content="ccop is a major import and export company" /> <meta name="keywords" content="coop, coop.com coop company, import export, import export france, " /> <meta name='REVISIT-AFTER' content='30 DAYS'> <title>coop is an import and export company located in France</title> </head> The reason I am asking, is because I want to know if there are better ways of constructing your SEO tags, and construction.

  • Should a project start with the client or the server?

    - by MadBurn
    Pretty simple question with a complex answer. Should a project start with the client or the server, and why? Where should a single programmer start a client/server project? What are the best practices and what are the reasons behind them? If you can't think of any, what reasons do you use to justify why you would choose to start one before the other? Personally, I'm asking this question because I'm finishing up specs for a project I will be doing for myself on the side for fun. But now that I'm finishing this phase, I'm wondering "ok, now where do I begin?" Since I've never done a project like this by myself, I'm not sure where I should start. In this project, my server will be doing all the heavy lifting and the client will just be sending updates, getting information from the server, and displaying it. But, I don't want that to sway the answer as I'm looking for more of an in depth and less specific answer that would apply to any project I begin in the future.

  • Learning Programming from scratch

    - by David542
    I am entirely new to programming, other than basic HTML/CSS knowledge. I want to learn programming as quickly and efficiently as possible, and I'm willing to put in the time (at least 70 hours a week). The reason I want to learn is because I have a startup that I've written a business plan for and have prototyped in Photoshop (both front-end and back-end pages). My goals is to have a prototype of the site up within 6 months. I have a good aptitude for math (A's in all math courses up through DiffEq and Linear Algebra). I assume learning programming from scratch can be a daunting task -- not because it is particularly difficult, but because there are so many areas and so much information. I want to make sure that I learn as efficiently as possible and have individuals (in addition to Google) to solicit advice from and that will help me when I get stuck or have questions. I know with other's help, my learning experience will be both more productive and enjoyable. What is the best way to find people that will help me in this? What are some good 'live' resources in addition to asking questions on Stack Overflow? Thank you very much for your time and help.

  • Benefits of Masters of Engineering Professional Practice for the lowly (yet aspiring) programmer

    - by Peter Turner
    I've been looking into in state online degree programs 'to fit my busy lifestyle' (i.e. three children, wife and hour and a half commute). One interesting one I've found is that Master of Engineering in Professional Practice. It looks more useful and practical than a MBA in project management. I'll contact the admission dept there about the specifics. But here I'm just asking in general. Do the courses in this degree apply to software engineering/development in even an abstract sense. The university I'm looking at does not have a Software Engineering major in the school of engineering. I'm not interested in architecture astronomy, but I am interested in helping my company succeed and being able to communicate technical information at a high and effective level as well as being able to lead my co-programmers toward a more robust end product. So my multipart question is: What might be the real benefit to me and my brain and How do I convince my boss (the owner of the company, who does do some tuition reimbursement) that just because it doesn't say anything about software that it might still do us some good? Oh, and how do I get past the fact that a masters degree would make me more qualified to be the project manager than... the project manager? (who is my supervisor)

  • Webserver on a rotating server with NAT IP or changing IPs

    - by hpsoftware
    i would have to elaborate my questions so please have patience Explaining the logic. if you are familiar with logmein then it installs a client software on your computer then it kinda keeps tracks where you computer is as long as it's connected to internet. So you can always access your computer no matter where it is whatever it's IP is you just go to logmein.com and then you can just access it. Now what i am asking 1. Let's assume i have a website hosted on my laptop let's call it webserver. so then i move around i have a new IP sometime even on a hotel network is it possible to do something like what logmein does so i can keep moving around my Webserver to new IP but it has some local client or something which keeps updating my IP or something i am sure i would need a gateway server somewhere which is connected to my domain name via DNS so somebody accessing my website www.mywebsite.com goes to my main server then gets routed to my laptop which could be anywhere but my gateway server is able to communicate to my webserver I will keep updating the case description based on comments to make more sense. please have patience with me.

  • High resolution graphical representation of the Earth's surface

    - by Simon
    I've got a library, which I inherited, which presents a zoomable representation of the Earth. It's a Mercator projection and is constructed from triangles, the properties of which are stored in binary files. The surface is built up, for any given view port, by drawing these triangles in an overlapping fashion to produce the image. The definition of each triangle is the lat/long of the vertices. It looks OK at low values of zoom but looks progressively more ragged as the user zooms in. The view ports are primarily referenced though a rectangle of lat/long co-ordinates. I'd like to replace it with a better quality approach. The problem is, I don't know where to begin researching the options as I am not familiar either with the projections needed nor the graphics techniques used to render them. For example, I imagine that I could acquire high resolution images, say Mercator projections although I'm open to anything, break them into tiles and somehow wrap them onto a graphical representation of a sphere. I'm not asking for "how do I", more where should I begin to understand what might be involved and the techniques I will need to learn. I am most grateful for any "Earth rendering 101" pointers folks might have.

  • Automated Acceptance tests under specific contraints

    - by HH_
    This is a follow up to my previous question, which was a bit general, so I'll be asking for a more precise situation. I want to automate acceptance testing on a web application. Briefly, this application allows the user to create contracts for subscribers with the two constraints: You cannot create more than one contract for a subscriber. Once a contract is created, it cannot be deleted (from the UI) Let's say TestCreate is a test case with tests for the normal creation of a contract. The constraints have introduced complexities to the testing process, mainly dependencies between test cases and test executions. Before we run TestCreate we need to make sure that the application is in a suitable state (the subscriber has no contract) If we run TestCreate twice, the second run will fail since the state of the application will have changed. So we need to revert back to the initial state (i.e. delete the contract), which is impossible to do from the UI. More generally, after each test case we should guarantee that the state is reverted back. And since, in this case, it is impossible to do it from the UI, how do you handle this? Possible solution: I thought about doing a backup of the database in the state that I desire, and after each test case, run a script which deletes the db and restores the backup. However, I find that to be too heavy to do for each single test case. In addition, what if some information are stored in files? or in multiple or unaccessible databases? My question: In this situation, what would an experienced tester do to write automated and maintanable tests. Thank you. More info: I'm trying to integrate tests into a BDD framework, which I find to be a neat solution for test documentation and communication, but it does not solve this particular problem (it even makes it harder)

  • How to add precedence to LALR parser like in YACC?

    - by greenoldman
    Please note, I am asking about writing LALR parser, not writing rules for LALR parser. What I need is... ...to mimic YACC precedence definitions. I don't know how it is implemented, and below I describe what I've done and read so far. For now I have basic LALR parser written. Next step -- adding precedence, so 2+3*4 could be parsed as 2+(3*4). I've read about precedence parsers, however I don't see how to fit such model into LALR. I don't understand two points: how to compute when insert parenthesis generator how to compute how many parenthesis the generator should create I insert generators when the symbols is taken from input and put at the stack, right? So let's say I have something like this (| denotes boundary between stack and input): ID = 5 | + ..., at this point I add open, so it gives ID = < 5 | + ..., then I read more input ID = < 5 + | 5 ... and more ID = < 5 + 5 | ; ... and more ID = < 5 + 5 ; | ... At this point I should have several reduce moves in normal LALR, but the open parenthesis does not match so I continue reading more input. Which does not make sense. So this was when problem. And about count, let's say I have such data < 2 + < 3 * 4 >. As human I can see that the last generator should create 2 parenthesis, but how to compute this? After all there could be two scenarios: ( 2 + ( 3 *4 )) -- parenthesis is used to show the outcome of generator or (2 + (( 3 * 4 ) ^ 5) because there was more input Please note that in both cases before 3 was open generator, and after 4 there was close generator. However in both cases, after reading 4 I have to reduce, so I have to know what generator "creates".

  • Using the Java SE 8 Date Time API with JPA 2.1

    - by reza_rahman
    Most of you are hopefully aware of the new Date Time API included in Java SE 8. If you are not, you should check them out right now using the Java Tutorial Trail dedicated to the topic. It is a significantly leap forward in processing temporal data in Java. For those who already use Joda-Time the changes will look very familiar - very simplistically speaking the Java SE 8 feature is basically Joda-Time standardized. Quite naturally you will likely want to use the new Date Time APIs in your JPA domain model to better represent temporal data. The problem is that JPA 2.1 will not support the new API out of the box. So what are you to do? Fortunately you can make use of fairly simple JPA 2.1 Type Converters to use the Date Time API in your JPA domain classes. Steven Gertiser shows you how to do it in an extremely well written blog entry. Besides explaining the problem and the solution the entry is actually very good for getting a better understanding of JPA 2.1 Type Converters as well. I think such a set of converters may be a good fit for Apache DeltaSpike as a Java EE 7 extension? In case you are wondering about Java SE 8 support in the JPA specification itself, Nick Williams has already entered an excellent, well researched JIRA entry asking for such support in a future version of the JPA specification that's well worth looking at. Another possibility of course is for JPA providers to start supporting the Date Time API natively before anything is formalized in the specification. What do you think?

  • CA For A Large Intranet

    - by Tim Post
    I'm managing what has become a very large intranet (over 100 different hosts / services) and will be stepping down from my role in the near future. I want to make things easy for the next victim person who takes my place. All hosts are secured via SSL. This includes various portals, wikis, data entry systems, HR systems and other sensitive things. We're using self signed certificates which worked o.k. in the past, but are now problematic because: Browsers make it harder for users to understand exactly what is going on when a self signed certificate is encountered, much less accept them. Putting up a new host means 100 phone calls asking what "Add an exception" means What we were doing is just importing the self signed certs when we set up a new workstation. This was fine when we only had a dozen to deal with, but now its just overwhelming. Our I.T. Department has classified this as ya all's problem, all we get from them is support for switch and router configurations. Beyond the user having connectivity, everything else is up to the intranet administrators. We have a mix of Ubuntu and Windows workstations. We'd like to set up our own self signed CA root, which can sign certificates for each host that we deploy on the intranet. Client browsers would of course be told to trust our CA. My question is, would this be dangerous and would we be better off going with intermediate certificates from someone like Verisign? Either way, I still have to import the root for the intermediate CA, so I really don't see what the difference is? Other than charging us money, what would Verisign be doing that we could not, beyond protecting the root CA cert so it can't be used to make forgeries?

    I'm looking for a language that will let me do what I could do with Clipper years ago, and which I can do with Tcl, namely add functionality in a way other than just adding functions. For example in Clipper/(x)Harbour there are commands #command, #translate, #xcommand and #xtranslate that allow things like this: #xcommand REPEAT; => DO WHILE .T. #xcommand UNTIL <cond>; => IF (<cond>); ;EXIT; ;ENDIF; ;ENDDO LOCAL n := 1 REPEAT n := n + 1 UNTIL n > 100 Similarly, in Tcl I'm doing proc process_range {_for_ project _from_ dat1 _to_ dat2 _by_ slice} { set fromDate [clock scan $dat1] set toDate [clock scan $dat2] if {$slice eq "day"} then {set incrementor [expr 24 * 60]} if {$slice eq "hour"} then {set incrementor 60} set method DateRange puts "Scanning from [clock format $fromDate -format "%c"] to [clock format $toDate -format "%c"] by $slice" for {set dateCursor $fromDate} {$dateCursor <= $toDate} {set dateCursor [clock add $dateCursor $incrementor minutes]} { # ... } } process_range for "client" from "2013-10-18 00:00" to "2013-10-20 23:59" by day Are there any other languages that permit this kind of, almost COBOL-esque, syntax modification? If you're wondering why I'm asking, it's for setting up stuff so that others with a not-as-geeky-as-I-am skillset can declare processing tasks.

  • PHP frameworks - should I use them?

    - by 30secondstosam
    First of all let me explain who I am: I am a PHP Developer working for a company developing their CMS which handles online stores, data feeds and other content like blogs. I have been programming for 6 years and 4 of those have been in PHP. (I used to be a C# developer). My question is regarding PHP frameworks. I see so many jobs asking for zend, cakephp and other MVC types of frameworks. However, even as an experienced developer I have never used a PHP framework. Should I start learning? If so where do I even start as there are so many. I am about to re-write so much of my work's CMS and I'm wondering whether I could help myself a lot by using a framework. What do people think? Considering I will be re-writing a lot of the online store stuff... I am experienced in OO and I have used the .NET framework in the past. Thanks in advance for the replies.

  • what are some good interview questions for a position that consists of reviewing code for security vulnerabilities?

    - by John Smith
    The position is an entry-level position that consists of reading C++ code and identifying lines of code that are vulnerable to buffer overflows, out-of-bounds reads, uncontrolled format strings, and a bunch of other CWE's. We don't expect the average candidate to be knowledgeable in the area of software security nor do we expect him or her to be an expert computer programmer; we just expect them to be able to read the code and correctly identify vulnerabilities. I guess I could ask them the typical interview questions: reverse a string, print a list of prime numbers, etc, but I'm not sure that their ability to write code under pressure (or lack thereof) tells me anything about their ability to read code. Should I instead focus on testing their knowledge of C++? Ask them if they understand what a pointer is and how bitwise operators work? My only concern about asking that kind of question is that I might unfairly weed out people who don't happen to have the knowledge but have the ability to acquire it. After all, it's not like they will be writing a single line of code, and it's not like we are looking only for people who already know C++, since we are willing to train the right candidate. (It is true that I could ask those questions only to those candidates who claim to know C++, but I'd like to give the same "test" to everyone.) Should I just focus on trying to get an idea of their level of intelligence? In other words, should I get them to talk and pay attention to the way they articulate their thoughts, and so on?

  • What's cool about Lisp nowadays? [closed]

    - by Kos
    Possible Duplicates: Why is Lisp useful? Is LISP still useful in today's world? Which version is most used? First of all, let me clarify: I'm aware of Lisp's place in history, as well as in education. I'm asking about its place in practical application, as of 2011. The question is: What features of Lisp make it the preferred choice for projects today? It's widely used in various AI areas as far as I know, and probably also elsewhere. I can imagine projects choosing, for instance... Python because of its concise, readable syntax and it being dynamic, Haskell for being pure functional with a powerful type system, Matlab/Octave for the focus on numerics and big standard libraries, Etc. When should I consider Lisp the proper language for a given problem? What language features make it the preferred choice then? Is its "purity and generality" an advantage which makes it a better choice for some subset of projects than the modern languages? edit- On your demand, a little rephrase (or simply a tl;dr) to make this more specific: a) What problems are solvable with Lisp much more easily than with more common, modern languages like Python or C# (or even F# or Scala)? b) What language features specific for Lisp make it the best choice for those problems?

  • Not allowed to upload .HTML files to my own DNN Site: Is it normal?

    - by Jake M
    My Question: Our webhost provider wont make it so we can upload .html files to our DNN site trhough the DNN File Manager page. Is that normal, should I push them to allow me to do this? We have recently transferred our website to a Dot Net Nuke run website. We originally had our website on a Linux server with Python scripts handling the backend. Obviously we now have a Windows server running .NET with ASP .NET code on the backend. Our webhost is a local Australian company. And they are saying we cant upload any .html files to the main part of the server, ie, www.ourdomain.com/Portals/0/. They are saying that the only place I can upload .html files is via FTP to this folder *www.ourdomain.com/Portals/0/html_content* This is a major problem for me because I am trying to upload my own skin which means I need to upload a main.html file to www.ourdomain.com/Portals/0/skins/myskin/ but they wont let me?! I guess what I am asking is, is this normal practice, why would they not allow this? As an experienced web admin for Linux servers and as someone who is used to being able to do whatever I want on my OWN server this is someing that really pis$%s me off!

  • How Can I Effectively Interview an Oracle Candidate?

    - by Tim Medora
    First, I browsed through SO for matching questions and didn't find one, but please point me in the right direction if this exact question has already been asked. I work with and around programmers of various skill levels on various platforms. I would consider my skills to be strong in terms of relational database design, query development, and basic performance tuning and administration. I'm mid-level when it comes to database theory. My team is looking to me to ensure that we have the best talent on staff, in this case, an engineer experienced in Oracle administration. To me, a well-rounded database administrator, regardless of platform, should also be competent in developing against the database so that is also a requirement. However my database skills are centralized around SQL Server 200x with experience in a few other products like SAP MaxDB, Access, and FoxPro. How can I thoroughly assess the skills of an Oracle engineer? I can ask high-level database theory questions and talk about routine tasks that are common across platforms, but I want to dig deep enough that I can be confident in the people I hire. Normally, I would alternate very specific questions that have a right/wrong answer with architectural questions that might have several valid answers. Does anyone have an interview template, specific questions, or any other knowledge that they can share? Even knowing the meaningful Oracle-related certifications would be a help. Thank you. EDIT: All the answers have been very helpful so far and I have given upvotes to everyone. I'm surprised that there are already 3 close votes on this question as "off topic". To be clear, I am specifically asking how a MS SQL Server engineer (like myself) can effectively interview a person with different but symbiotic skills. The question has already received specific, technical answers which have improved my own database design and programming skills. If this is more appropriate as a community wiki, please convert it.

  • How to forward AIM to Gmail

    - by iamjames
    Still have an old AIM email address lying around and would like to forward it to Gmail?  Here's how: 1.  Login to your AIM and click on Settings on the far right 2.  In the left menu click IMAP and POP  3.  This shows you your IMAP and POP setup information for AIM.  We're going to put this into your Gmail account so your Gmail account will check your AIM account and download all AIM emails. 4.  Login to your Gmail, click Settings and click Accounts and Import 5.  Click "Import mail and contacts".  A new window will pop up asking what account you want to import.  Enter your AIM Email Address and click Continue 6.  The next page asks for your password.  Enter your password and click Continue.  Step 2 asks your Import options.  I'd put a checkmark in "Leave a copy of retrieved message on server".  That way all your mail is still stored on AIM if you ever need it. 7.  Click Start import and you're done.  Next screen says it make take several hours up to 2 days before you start seeing imported messages and can check the status at Settings > Accounts and Import

  • Where to Start?

    - by freemann098
    my name is Chase. I've been programming for over 3 years now and I've made very little progress towards game development. I blame myself for it due to reasons. I have experience in many languages such as C++, C#, and Java. I have a little bit of knowledge in JavaScript/HTML and Python. My question is where to start on actually understanding jumping into game development. Whenever I watch game development tutorials it mostly makes sense until points of things like OpenGL or advanced topics that make no sense at all. An example is something like glOrhho Matrix or whatever. Videos either don't explain things like this or they're not explained very well. Do I not know enough basics? I find myself always copying code from a video but understanding very little of it. It's like i'm memorizing things I don't understand which makes it hard to program at all. If I were to want to get to the point where I could write my own game engine or just a game by myself in general in C++ using at the most documentation how would I start at mastering to that level. Should I learn C first, or get really good at basics in general with C++. I know there is a similar posted question on this site but it's not the same due to the fact the person asking the question has a well knowledge level in programming. I'm stuck in a loop of learning the same things but if I go farther I don't understand. I'm stuck in the same spot and need to make progress.
