  • How to wrap console utils in webserver

    - by Alex Brown
    I have a big dataset (100Mbs/day) and a bunch of console a TCL/TK tools to view it - I want to turn it into a web app that I can build, and others can maintain. In long: my group runs simulations yielding 100s of Mbs of data daily, in multiple (mostly but not only) text forms. We have a bunch of scripts and tools, mostly old school 1990's style stuff requiring a 5-button mouse, as well as lots of ad-hoc scripts that engineers build out of frustration every month or so. These produces UIs, graphs, spreadsheets (various sizes), logs, event histories etc. I want to replace (or at least supplement) the xwindows / console style UI with a web-based one, so I need the following properties: pleasant to program can wrap existing command-line tools in separate views (I don't need to scrape GUIs or anything) as I port logic from the existing scripts I can create a modularised and pleasant codebase to replace it I can attach a web-ui to navigate between views - each view is likely to contain keys which might make sense to view in another I am new to building systems that have logic on the back-end and front-end of a web-server. from that point of view, they do this: backend wraps old-school executables, constructs calls into them and them takes the output and wraps it up, niceifies it and delivers it to the web client. For instance the tool might generate a number of indexed images (per invocation) which I might deliver all at once or on-demand. May (probably) need to to heavy stats on some sources. frontend provides navigation connecting multiple views, performs requests from one view for data from another (or self to self), etc. Probably will have some views with a lot of interactivity. Can people please point me towards viable solutions for this? I know it's a bit of an open question so as answers come in I hope to refine the spec until we have a good match. I guess I expect to see answers like "RoR!" "beans!" "Scala!" but please give an indication of why those are a good fit; I know nothing! I got bumped off SO for asking an open-ended question, so sorry if its OT here too (let me know). I take the policy that I use the best/closest matched language for a project but most of my team are extremely low level (ie pipeline stages and CDyn) so I don't have the peer group to know where to start.

  • Why profile applications using AOP?

    - by Vance
    When tuning performance in a web application, I am looking for good and light-weight performance profiling tools to measure the execution time for each method. I know that the easiest profiling method is to log the start time and end time for each method, but I see more and more people using AOP to profile (add @profiled before each method). What's the benefit of AOP profiling compared to the common "log" way? Thanks in advance Vance

  • Effectiveness and Efficiency

    - by Daniel Moth
    In the professional environment, i.e. at work, I am always seeking personal growth and to be challenged. The result is that my assignments, my work list, my tasks, my goals, my commitments, my [insert whatever word resonates with you] keep growing (in scope and desired impact). Which in turn means I have to keep finding new ways to deliver more value, while not falling into the trap of working more hours. To do that I continuously evaluate both my effectiveness and my efficiency. EFFECTIVENESS The first thing I check is my effectiveness: Am I doing the right things? Am I focusing too much on unimportant things? Am I spending more time doing stuff that is important to my team/org/division/business/company, or am I spending it on stuff that is important to me and that I enjoy doing? Am I valuing activities that maybe I have outgrown and should be delegated to others who are at a stage I have surpassed (in Microsoft speak: is the work I am doing level appropriate or am I still operating at the previous level)? Notice how the answers to those questions change over time and due to certain events, so I have to remind myself to revisit them frequently. Events that force me to re-examine them are: change of role, change of team/org/etc, change of direction of team/org/etc, re-org, new hires on the team that take on some of the work I did, personal promotion, change of manager... and if none of those events has occurred since the last annual review, I ask myself those at each annual review anyway. If you think you are not being effective at work, make a list of the stuff that you do and start tracking where your time goes. In parallel, have a discussion with your manager about where they think your time should go. Ultimately your time is finite and hence it is your most precious investment, don't waste it. If your management doesn't value as highly what you spend your time on, then either convince your management, or stop spending your time on it, or find different management: Lead, Follow, or get out of the way! That's my view on effectiveness. You have to fix that before moving to being efficient, or you may end up being very efficient at stuff that nobody wants you to be doing in the first place. For example, you may be spending your time writing blog posts and becoming better and faster at it all the time. If your manager thinks that is not even part of your job description, you are wasting your time to satisfy your inner desires. Nobody can help you with your effectiveness other than your management chain and your management peers - they are the judges of it. EFFICIENCY The second thing I check is my efficiency: Am I doing things right? For me, doing things right means that I deliver the same quality of work faster [than what I used to, and than my peers, and than expected of me]. The result is that I can achieve more [than what I used to, and than my peers, and than expected of me]. Notice how the efficiency goal is a more portable one. If, by whatever criteria, you think you are the best at [insert your own skill here], this can change at two events: because you have new colleagues (who are potentially better than your older ones), and it can change with a change of manager (who has potentially higher expectations). That's about it. Once you are efficient at something, you carry that with you... All you need to really be doing here is, when taking on new kinds of work that you haven't done before, try a few approaches and devise a system so that you can become efficient at this new activity too... Just keep "collecting" stuff that you are efficient at. If you think you are not being efficient at something, break it down: What are the steps you take to complete that task? How long do you spend on each step? Talk to others about what steps they take, to see if you can optimize some steps away or trade them for better steps, or just learn how to complete a step faster. Have a system for every task you take so that you can have repeatable success. That's my view on efficiency. You have to fix it so that you can free up time to do more. When you plan a route from A to B - all else being equal - you try to get there as fast as possible so why would you not want to do that with your everyday work? For example, imagine you are inefficient at processing email: You spend more time than necessary dealing with email, and you still end up with dropped email threads and with slower response times than others. How can you improve? Talk to someone that you think is good at this, understand their system (e.g. here is my email processing system) and come up with one that works for you. Parting Thoughts Are you considered, by your colleagues and manager, an effective and efficient person at your workplace? If you are, what would you change if you were asked by your management to do the job of two people? Seriously, think about that! Your immediate reaction may be "that is not possible", but it actually is. You just have to re-assess what things that were previously important will now stop being important, by discussing them with your management and reaching agreement on relative priorities. For example, stuff that was previously on your plate may now have to be delegated or dropped. Where you thought you were efficient, maybe now you have to find an even faster path to completion, perhaps keeping in mind that Perfect is the Enemy of “Good Enough”. My personal experience (from both observing others and from my own reflection) is that when folks are struggling to keep up at work it is because of two reasons: They are investing energy in stuff that they enjoy doing which the business regards as having a lower priority than a lot of other things on their plate. They are completing tasks to a level of higher quality than what is required (due to personal pride) missing the big picture which almost always mandates completing three tasks at good enough quality than knocking only one of them out of the park while the other two come in late or not at all. There is a lot of content on the web, so I strongly encourage you to use your favorite search engine to read other views on effectiveness and efficiency (Bing, Google).

  • Where can I find a list of local japanese game publishers

    - by Erik
    What would be a good starting point for locating small or medium size game publishers in Japan. We have a US/EU released game that we believe will fit the Japanese market well, and are looking for companies that we could contact for possible co-publishing. EDIT: So far, I've found http://www.gamebusiness.jp/directory/category.php?id=10002 and from one answer, http://www.gamedevmap.com/index.php?query=Japan&Submit=Search Starting a bounty, I need as many publishers as I can get.

  • What are the advantages of mainframes?

    - by Scott Weinstein
    The downsides of Mainframes is well trodden ground; expensive, legacy, dwindling community, etc. I'm not particularly interested in the downsides, but I am curious if there are any benefits to mainframe hardware/software over the current Intel/AMD & Linux/Windows environment. I've been told that MFs are particularly good (and better than current servers) at heavy I/O loads. Is this still true?

  • Frontend development, where to start?

    - by glitch
    I've been stuck on the backend for years now, working on webservices, DBs, SDKs, APIs and all that jazz, and so that's an area that I have a decent grasp of, but I've absolutely no clue about how the frontend works. What's a good place to start for a backend monkey like me who wants to learn the best practices, latest technologies and the philosophy behind modern web page design and its interaction with the server? I want to be cool like all of the other javascript kids. Thanks!

  • Is there any evidence that lisp actually is better than other languages at artificial intelligence?

    - by Joe D
    I asked this question on SO but it was closed fairly promptly (within 3 minutes) because it was too subjective. I then thought to ask it here on Programmers, a site for "subjective questions on software development". Quoting from the original question: There seems to be a long-held belief (mainly by non-lispers) that lisp is only good for developing AI. Where did this belief originate? And is there any basis in fact to it?

  • DotNetNuke is switching to C#, uh oh

    - by Chris Hammond
    If you didn’t see Shaun’s blog post earlier this week you should give it a good read through . The post announced the fact that starting with Version 6.0 (targeted for Q2 2011) DotNetNuke will no longer be developed/released as a VB.NET Application. All development of the core platform will be in C# (this does not mean that the community modules for the platform will change languages).

Such as, is there a good website that has compiled open source games? I don't want an answer of "go google it" or "en.wikipedia.org/wiki/List_of_open_source_Android_applications" it gets really annoying on posts when people just give lazy answers.

  • HTG Explains: Do You Really Need to Safely Remove USB Sticks?

    - by Chris Hoffman
    You’ve probably heard that you always need to use the Safely Remove Hardware icon before unplugging a USB device. However, there’s also a good chance that you’ve unplugged a USB device without using this option and everything worked fine. Windows itself tells you that you don’t need to use the Safely Remove Hardware option if you use certain settings – the default settings – but the advice Windows provides is misleading.

  • Are proofs worth the effort?

    - by Shashank Jain
    I bought the de-facto book for learning about data structures and algorithms (CLRS). The book is though quite good but the singularity is in the proofs. The book is filled with Lemmas, theorems, peculiar symbols and unimaginable recurrence relations which are very hard to understand. I am able to somehow get the algorithms but the discrete mathematics just not for me. So should I leave them out and just concentrate on algorithims?
