  • "44 Tips" in PHP Magazin and Other NetBeans IDE Screencasts

    - by Geertjan
    My recent YouTube series "44 Tips for Front End Web Devs" (part 1, part 2) has been picked up by PHP Magazin: http://phpmagazin.de/news/Frontend-Entwicklung-mit-NetBeans-IDE-168339 Great. I'm working on more screencasts like that, from different angles. For example, one will methodically explain each and every window in NetBeans IDE; another will step through the creation of an application from conception to deployment; while another will focus on the NetBeans IDE extension points and how easily they can be used to add new features to NetBeans IDE. The screencast approach has, I think, a lot of advantages. They take less time to make and they seem to be more effective, in several ways, than tutorials. Hearing someone talk through a scenario seems to also put things in a clearer perspective than when you have everything written out in a document, where small details get lost and diversions are more difficult to make. Anyway, onwards to more screencasts. Any special requests?

  • How important is it for a programmer to have an online presence?

    - by Jer
    I've noticed more and more mentions (both in posts here and in actual job descriptions) of programmers's "portfolios" - typically their public profiles on sites such as this, github, etc. How important is this, and would companies (startups in particular) reject (or immediately discard withouth even interviewing) otherwise outstanding candidates who don't have an online presence? Personally, I prefer to keep a very low profile online. My name here cannot identify me, and I have other handles for other sites. I have a very spartan (and completely private) Facebook page. I do code on my own but the code lives in local repositories. In general, the less information online about me, the better. I could see a designer needing some sort of online portfolio, but for a programmer, is this really a big negative when job-searching?

  • Some mail details about Orange Mauritius

    Being an internet service provider is not easy after all for a lot of companies. Luckily, there are quite some good international operators in this world. For example Orange Mauritius aka Mauritius Telecom aka Wanadoo(?) aka MyT here in Mauritius. The local circumstances give them a quasi-monopol position on fixed lines for telephony and therefore cable-based DSL internet connectivity. So far, not bad but as usual... the details. Just for the records, I am only using the services of Orange for mobile but friends and customers are bound, eh stuck, with other services of Orange Mauritius. And usually, being the IT guy, they get in touch with me to complain about problems or to ask questions on either their ADSL / MyT connection, mail services or whatever. Most of those issues are user-related and easily to solve by tweaking the configuration of their computer a little bit but sometimes it's getting weird. Using Orange ADSL... somewhere else Now, let's imagine we are an Orange ADSL customer for ages and we are using their mail services with our very own mail address like "[email protected]". We configured our mail client like Thunderbird, Outlook Express, Outlook or Windows Mail as publicly described, and we are able to receive and send emails like a champion. No problems at all, the world is green. Did I mention that we have a laptop? Ok, let's take our movable piece of information technology and visit a friend here on the island. Not surprising, he is also customer of Orange, so we can read and answer emails. But Orange is not the online internet service provider and one day, we happen to hang out with someone that uses Emtel via WiMAX or UMTS.. And the fun starts... We can still receive and read emails from our Orange mail account and the IT world is still bright but try to send mails to someone outside the domain "@intnet.mu" or "@orange.mu". Your mail client will deny sending mail with SMTP message 5.1.0 "blah not allowed". First guess, there is problem with the mail client, maybe magically the configuration changed over-night. But no it is still working at home... So, there is for sure a problem with the guy's internet connection. At least, it is his fault not to have Orange internet services, so it can not work properly... The Orange Mail FAQ After some more frustation we finally checkout the Orange Mail FAQ to see whether this (obviously?) common problem has been described already. Sorry, but those FAQ entries are even more confusing as it is not really clear how to handle this scenario. Best of all is that most of the entries are still refering to use servers of the domain "intnet.mu". I mean Orange will disable those systems in favour of the domain "orange.mu" in the near future and does not amend their FAQs. Come on, guys! Ok, settings for POP3 are there. Hm, what about the secure version POP3S? No signs at all... Even changing your mail client to use password encryption with STARTTLS is not allowed at all. Use "bow.intnet.mu" for incoming mail... Ahhh, pretty obvious host name. I mean, at least something like pop.intnet.mu or pop3.intnet.mu would have been more accurate. Funny of all, the hostname "pop.orange.mu" is accessible to receive your mail account. Alright, checking SMTP options for authentication or other like POP-before-SMTP or whatever well-known and established mechanism to send emails are described. I guess that spotting a whale or shark in Mauritian waters would be easier. Trial and error on SMTP settings reveal that neither STARTTLS or any other connection / password encryption is available. Using SSL/TLS on SMTP only reveals that there is no service answering your request. Calling customer service So, we have to bite into the bitter apple and get in touch with Orange customer service and complain/explain them our case and ask for advice. After some hiccups, we finally manage to get hold of someone competent in mail services and we receive the golden spoon of mail configuration made by Orange Mauritius: SMTP hostname: smtpauth.intnet.mu And the world of IT is surprisingly green again. Customer satisfaction? Dear Orange Mauritius, what's the problem with this information? Are you scared of mail spammer? Why isn't there any case in your FAQs? Ok, talking about your FAQs - simply said: they are badly outdated! Configure your mail client to use server name based in the domain intnet.mu but specify your account username with orange.mu as domain part. Although, that there are servers available on the domain orange.mu after all. So, why don't you provide current information like this: POP3 server name: pop.orange.muSMTP server name: smtp.orange.muSMTP authenticated: smtpauth.orange.mu It's not difficult, is it? In my humble opinion not really and you would provide clean, consistent and up-to-date information for your customers. This would produce less frustation and so less traffic on your customer service lines. Which after all, would improve the total user experience and satisfaction level on both sides. Without knowing these facts. Now, imagine you would take your laptop abroad and have to use other internet service providers to be able to be online... Calling your customer service would be unnecessary expensive!

  • Screencast several application windows at once in Microsoft Windows

    - by Birt
    I have several (20+) applications running on a Microsoft Windows PC. What I would like is a solution that allows me to broadcast the window of each application in a webpage, in readonly mode (there's no need for the users to interact with it). This should work even if the application is in the background, seeing that there's no way to fit all of them on the screen. I performed very extensive searching, from simple screencasting apps such as Camtasia, CamStudio or VHScrCap to things like VNC (haven't found any server able to broadcast multiple windows at once, much less background windows) and even application virtualization, but in the end I haven't found anything that fits my needs. Most solutions that allow capturing a window instead of the whole desktop will not let you capture multiple windows but only a single window and on top of that they don't even work when the window is in the background.

  • Who are the outspoken critics of Object-Oriented design?

    - by Xepoch
    Sure, object-oriented techniques are great and have stuck around for a while. I know only less than a handful of critics of the OO principles. It seems as though most non-OO designs and architectures are shunned, yet we continue to write a lot of good software in C and solve a lot of data changes via awk/sed and countless other examples. Correct tool for the correct job, yes? I'm having a hard time finding articles, presentations, or published criticisms of OO (even Fred Brooks has blessed information hiding). Are there any well-known, published and/or outspoken critics of OO?

  • What incidentals do server maintenance people/devs need?

    - by SeniorShizzle
    I'm trying to put together a thank-you package for clients who are server-side developers and in charge of their company's servers and databases. Since I've never been in that line of work before, I would like to know what it is like. Get inside your heads, for instance. My first thought was (don't hate me) a few patch cables. I don't know if you guys actually need these often or anything. What are some similar things that you like or need for your lives at work. Small incidentals less than $10 are preferred, like Coffee or a notebook, screwdrivers. Et cetera.

  • What's the format of Real World Performance Day?

    - by william.hardie
    A question that has cropped a lot of late is "what's the format of Real World Performance Day?" Not an unreasonable question you might think. Sure enough, a quick check of the Independent Oracle User Group's website tells us a bit about the Real World Performance Day event, but no formal agenda? This was one of the questions I posed to Tom Kyte (one of the main presenters) in our recent podcast. Tom tells us that this isn't your traditional event where one speaker follows another with loads of slides. In fact, the Real World Performance Day features Tom and fellow Oracle performance experts - Andrew Holdsworth and Graham Wood - continuously on stage throughout the day. All three will be discussing database performance challenges and solutions from development, architectural design and management perspectives. There's going to be multi-terabyte demos on show, less of the traditional slides, and more interactive debate and discussion going on. Tune-in and hear what else Tom has to say about this fairly unique event!

  • Your Next IT Job

    - by BuckWoody
    Some data professionals have worked (and plan to work) in the same place for a long time. In organizations large and small, the turnover rate just isn’t that high. This has not been my experience. About every 3-5 years I’ve changed either roles or companies. That might be due to the IT environment or my personality (or a mix of the two), but the point is that I’ve had many roles and worked for many companies large and small throughout my 27+ years in IT. At one point this might have been a detriment – a prospective employer looks at the resume and says “it seems you’ve moved around quite a bit.” But I haven’t found that to be the case all the time –in fact, in some cases the variety of jobs I’ve held has been an asset because I’ve seen what works (and doesn’t) in other environments, which can save time and money. So if you’re in the first camp – great! Stay where you are, and continue doing the work you love. but if you’re in the second, then this post might be useful. If you are planning on making a change, or perhaps you’ve hit a wall at your current location, you might start looking around for a better paying job – and there’s nothing wrong with that. We all try to make our lives better, and for some that involves more money. Money, however, isn’t always the primary motivator. I’ve gone to another job that doesn’t have as many benefits or has the same salary as the current job I’m working to gain more experience, get a better work/life balance and so on. It’s a mix of factors that only you know about. So I thought I would lay out a few advantages and disadvantages in the shops I’ve worked at. This post isn’t aimed at a single employer, but represents a mix of what I’ve experienced, and of course the opinions here are my own. You will most certainly have a different take – if so, please post a response! I also won’t mention a specific industry – I’ve worked everywhere from medical firms, legal offices, retail, billing centers, manufacturing, government, even to NASA. I’m focusing here mostly on size and composition. And I’m making some very broad generalizations here – I am fully aware that a small company might have great benefits and a large company might allow a lot of role flexibility.  your mileage may vary – and again, post those comments! Small Company To me a “small company” means around 100 people or less – sometimes a lot less. These can be really fun, frustrating places to to work. Advantages: a great deal of flexibility, a wide range of roles (often at the same time), a large degree of responsibility, immediate feedback, close relationships with co-workers, work directly with your customer. Disadvantages: Too much responsibility, little work/life balance, immature political structure, few (if any) benefits. If the business is family-owned, they can easily violate work/life boundaries. Medium Size company In my experience the next size company I would work for involves from a few hundred people to around five thousand. Advantages: Good mobility – fairly easy to get promoted, acceptable benefits, more defined responsibilities, better work/life balance, balanced load for expertise, but still the organizational structure is fairly simple to understand. Disadvantages: Pay is not always highest, rapid changes in structure as the organization grows, transient workforce. You may not be given the opportunity to work with another technology if someone already “owns” it. Politics are painful at this level as people try to learn how to do it. Large Company When you get into the tens of thousands of folks employed around the world, you’re in a large company. Advantages: Lots of room to move around – sometimes you can work (as I have) multiple jobs through the years and yet stay at the same company, building time for benefits, very defined roles, trained managers (yes, I know some of them are still awful – trust me – I DO know that), higher-end benefits, long careers possible, discounts at retailers and other “soft” benefits, prestige. For some, a higher level of politics (done professionally) is a good thing. Disadvantages: You could become another faceless name in the crowd, might not allow a great deal of flexibility,  large organizational changes might take away any control you have of your career. I’ve also seen large layoffs happen, and good people get let go while “dead weight” is retained. For some, a higher level of politics is distasteful. So what are your experiences?

  • Slideshows in elastic or fluid layouts?

    - by aendrew
    Hi folks, I'm building a new WordPress TwentyTen child theme using the ElastiCSS framework ( http://elasticss.com/ ) and am trying to figure out the best way of using some sort of dynamic content slideshow. What is the best way to implement a slideshow in a fluid or elastic layout such that it remains proportional to the other items in the content area? Should I even bother trying to obtain that? Or should I use like four different sizes in conjunction with something like the Less framework ( http://lessframework.com/ )? Thanks! (BTW, I've posted here because this was more of a "what's the best option" question than a "How do I program that?" question. If you think it would be more appropriate on SO, please move it there.)

  • Do search engines directly penalize bad grammar?

    - by Nicolas Raoul
    Let's say I have a web page with user-contributed content, which is good content but with bad grammar, slang terms, inappropriate tone. I know that bad grammar is a also a problem because it drives away visitors and scares people from linking to it, but let's put that aside. Let's also put aside the fact that incorrectly spelt terms might be ignored by a crawler, potentially leading to less text-comparizon hits. QUESTION: Do search engines like Google directly recognize and penalize bad grammar? For instance because they might consider bad-grammar as a sign of low-quality content.

  • Health problem of a programmer

    - by gunbuster363
    Hi all, I've been annoyed by this fingers ache for quite a long time, my fingers ache because of too much mouse clicking during office hour plus play games after work. I forget game for a while and my fingers are getting better, but still my right pointing finger would feel pressure when I click the mouse. I haven't go to a doctor because I afraid the fee would be high and he would just suggest me too get rest for the fingers, also, I don't know what kind of doctor should I go and see. My fingers get less pressure if I use my expensive deathadder ( what a shame, I bought this for gaming, but now I use it for rest ) at home because its buttons are softer, however I cannot have such expensive mouse at my office because I am afraid people would steal it. I use some trick when I am using the mouse such as single-click open a file, adding more shortcuts at desktop for common jobs, do you guys have some other tips for me? Thank you.

  • Difference between a pseudo code and algorithm?

    - by Vamsi Emani
    Technically, Is there a difference between these two words or can we use them interchangeably? Both of them more or less describe the logical sequence of steps that follow in solving a problem. ain't it? SO why do we actually use two such words if they are meant to talk of the same? Or, In case if they aren't synonymous words, What is it that differentiates them? In what contexts are we supposed to use the word pseudo code vs the word algorithm? Thanks.

    In college me and my friends use to play cards all the time. I want to make a game for that. It's quite similar to hearts, a kind of modified hearts which we made up. I want to make a multiplayer game which could be played over the internet. Plus there should also be an option for computer to play if less players availiable at the time. I don't want to make a exe. I want to play in browser. How should I go about it.

  • What is the supposed productivity gain of dynamic typing?

    - by hstoerr
    I often heard the claim that dynamically typed languages are more productive than statically typed languages. What are the reasons for this claim? Isn't it just tooling with modern concepts like convention over configuration, the use of functional programming, advanced programming models and use of consistent abstractions? Admittedly there is less clutter because the (for instance in Java) often redundant type declarations are not needed, but you can also omit most type declarations in statically typed languages that usw type inference, without loosing the other advantages of static typing. And all of this is available for modern statically typed languages like Scala as well. So: what is there to say for productivity with dynamic typing that really is an advantage of the type model itself?

  • Algorithms and Programmer's day-to-day job

    - by Lior Kogan
    As of July 10, 2012, Stack Overflow contains 3,345,864 questions, out of which 20,840 questions are tagged as "Algorithm" - this is less than 0.6% ! I find it disturbing. Many programmers have several years of academic education in computer science / software engineering. Most of them are smart... When asked, most would say that they love algorithms. Computer programming is generally about solving problems using algorithms... Yet, only 1 of 160 questions is tagged as algorithm related. What does it say about our profession?

  • Repurpose a Kobo Reader as a Weather Station

    - by Jason Fitzpatrick
    Last month we showed you a clever hack that converted an old Kindle into a weather station; this new hack uses a Kobo ebook reader (cheaper hardware) and ditches the external server (less overhead). Even better, this new hack is simpler to deploy. You’ll need a Kobo unit, a free installer bundle courtesy of Kevin Short over at the MobileRead forums, and a few minutes to toggle on telnet access to your Kobo and run the installer.

  • Should I block bots from my site and why?

    - by Frank E
    My logs are full of bot visitors, often from Eastern Europe and China. The bots are identified as Ahrefs, Seznam, LSSRocketCrawler, Yandex, Sogou and so on. Should I block these bots from my site and why? Which ones have a legitimate purpose in increasing traffic to my site? Many of them are SEO. I have to say I see less traffic if anything since the bots have arrived in large numbers. It would not be too hard to block these since they all admit in their User Agent that they are bots.

  • Are Meta tags useful for SEO?

    - by Lynda
    Reading a Search Results with this or a similar phrased question can lead to reading a lot of conflicting answers. Are there any meta tags that matter in SEO? From what I have read I do know that meta keywords are no longer used (or so little it is not worth using them) and don't worry with using them. Meta Description tags are not used for page ranking but can effect click through rates so should be used but be less than 160 characters. I know the following meta tags exist: author - the author's name and possibly email address robots - to allow or disallow indexing by robots copyright - the copyright date of the page How much do these meta tags matter and are there others that are new (including ones that may not be used by all but might be used in the future or are used by only one of the big players like Google or Bing) meta tags that should be included? Note: Even if a meta tag doesn't matter in SEO but helps with click through rates similar to the descript tag does then feel free to include it with your answer.

  • AWR Performance Report and Read by Other Session Waits

    - by user702295
    For the questions regarding "read by other session" and its relation to "db file sequential/scattered read", the logic is like this: When a "db file sequential/scattered read" is done, the blocks are either already in the cache or on the disk.  Since any operation on blocks is done in the cache and since and the issue is "read by other session" I will relate to the case the blocks are on the disk. Process A is reading the needed block from the disk to the cache.  During that time, if process B (and C and others) need the same block, it will wait on "read by other session".  A and B can be threads of the same process running in parallel or unrelated processes.  For example two processes doing full table scan on mdp_matrix etc. Solutions for that can be lowering the number of processes competing on the same blocks, increasing PCTFREE.  If it is a full table scan, maybe an index is missing that can result in less blocks being read from the cache and so on.

  • Is there a simpler way to create a borderless window with XNA 4.0?

    - by Cypher
    When looking into making my XNA game's window border-less, I found no properties or methods under Game.Window that would provide this, but I did find a window handle to the form. I was able to accomplish what I wanted by doing this: IntPtr hWnd = this.Window.Handle; var control = System.Windows.Forms.Control.FromHandle( hWnd ); var form = control.FindForm(); form.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; I don't know why but this feels like a dirty hack. Is there a built-in way to do this in XNA that I'm missing?

  • Pair Programming: Pros and Cons

    - by O.D
    I need some experience reporting from the ones who have done pair programming, I noticed that lots of people recommend it but my experience was that at one point it's more efficient to sit alone, think and then write code than to talk with the other programmer (which can be very annoying to other programmers in the same office), do you agree to this? and if yes can you mention situations where pair programming is less efficient than traditional programming? Actually, I'm more interested in Cons than in Pros, but if it's your own experience I would like to read both, the Cons and the Pros. I would like to read what you think about the Programmer who doesn't have the keyboard, what can he do in the meanwhile other than talking about the concept? or checking the code on the screen?

    Nearly half of CFOs are planning to reduce their inventory during the first half of 2010 in part due to supply chain improvements that allow them to hold less product, but also because of reduced demand according to Kate O'Sullivan, Sr Editor at CFO Magazine. Her view is based on this quarter's Duke University Global Business Outlook Survey. Highlights: Employment will be a drag on the economy- full-time employment to increase by 1%. Temp hiring to grow <1%, Outsourcing 4%.  70% of CFOs at SMEs say credit conditions are worse then 12 mos ago - placing strains on inventory growth Asia and China finance execs are more optimistic than their EMEA or US counterparts and expect stronger growth in capital spending with a 16% gain Source: "Slouching Towards Recovery", CFO Magazine, April 2010, pgs 19-20

  • How can I let prospective employers know I'm a great developer?

    - by Zoe Gagnon
    I've recently read through Joel's guide to finding great developers (http://www.joelonsoftware.com/articles/FindingGreatDevelopers.html), and I feel really strongly that I am smart and get things done. The problem is, I didn't learn how to get things done until about halfway through college, so my GPA is less than stellar. Additionally, I've got a few other things going against me: late into the job market (~30), no internship, state college instead of university, and when I graduated, I pretty much had to take the first job that offered. With all of these things piled together, my resume (the first step to getting a job), is not terribly impressive. What can I do to let people know that I'm a great developer and would complement the best companies in the world?
