    Android 5.1’s new “ignore wireless networks without internet” feature (which does not have any way to be toggled off) basically disconnects from wifi networks lacking internet. This will cause major issues for tech gadgets such as the Chromecast, GoPro, Parrot’s Lineup of Drones (Bebop, ARDrone, etc). Basically all of these devices create a WiFi network that has no internet connectivity and in Android 5.1 the behavior is to automatically disconnect from these networks. I confirmed this on a Bebop and Chromecast so far as have other users. Yikes! Wonder how many months until Google…

It’s such a great example of Abbott’s hopelessness: He survived as Prime Minister after a failed party room spill motion only to deliver another classic clanger. Good job, Tony. Then I checked the date and realised it had only been 38 days since the attempted spill. It seems much longer because barely a day goes by without a spectacular cock-up or gaffe by Abbott or one of his…

    Ag: faster than Ack Some nice performance tricks; I particularly like the use of sljit: Ag uses Pthreads to take advantage of multiple CPU cores and search files in parallel. Files are mmap()ed instead of read into a buffer. Literal string searching uses Boyer-Moore strstr. Regex searching uses PCRE’s JIT compiler (if Ag is built with PCRE >=8.21). Ag calls pcre_study() before executing the same regex on every file. Instead of calling fnmatch() on every pattern in your ignore files, non-regex patterns are loaded into arrays and binary searched. (tags: jit cli grep search ack ag unix…

    The LibreOffice project was announced with great fanfare in September 2010. Nearly one year later, the project (from which LibreOffice was forked) was cut loose from Oracle and found a new home as an Apache project. It is fair to say that the rivalry between the two projects in the time since then has been strong. Predictions that one project or the other would fail have not been borne out, but that does not mean that the two projects are equally successful. A look at the two projects' development communities reveals some interesting differences. Click below (subscribers only)…

  • After a hit game, indie developers struggle to replicate success

    26 Mar 2015 | 4:04 pm
    Bithell has become one of a growing number of prominent indie game developers known by name after releasing a hit game. New platforms like Steam and iOS have made it easier than ever for a single developer to create a successful game, and sometimes those games really blow up - developers like Minecraft creator Markus "Notch" Persson have become fast millionaires solely off of a single title. But after the elation of a hit game comes a sudden realization: you need to make another one. This is pretty common among artists; the second album is always the hardest.
  • Microsoft rebrands Universal apps as "Windows apps"

    In the beginning there was the word, and the word was Metro. And then it was Windows 8-style. And then it was Modern. And then it was Windows Store. And then it was Universal. And today, Microsoft has decreed that henceforth these apps - which are all ultimately based on Windows Runtime - will be known as Windows apps. Historically, of course, "Windows apps" (or "Windows programs") referred to standard, Win32-based executables that ran on the Windows desktop. Under the new naming scheme, these Win32 apps will now be called Windows desktop applications. As you can see in the slide above,…

(If you need a primer on the phenomenon of gara-kei, you should probably read up on that here, but in short, it's how Japan's mobile phone market sped ahead with early technologies, then faltered when smartphone competition…

A 256 GB solid state drive standard. A 1920x1080p IPS display, once again standard. ASUS has really raised the bar for what someone can expect in a mid-range device. I honestly cannot believe that you can buy this much laptop for that kind of money these…

  • One name really stuck out - Zorin OS

    Good morning / evening / afternoon / day / night whenever you are reading this. My name is Antonio and I really like Zorin OS.I'm fairly new to the Linux community and I had a difficult time around at first when I stumbled across a few threads that were just distro wars. These sort threw me off track and I completely botched my first Arch linux install. Afterwards however, I found Ubuntu and found it to my liking for much except for a few things.The first thing was the interface. Unity isn't ugly, but I prefer something a little more like the Windows UI that isn't controlled by a brown-orange…

  • A non-techie’s perspective on blogging with Jekyll

    Scott Nesbitt
    26 Mar 2015 | 3:12 am
    As you probably know, I blog quite a bit. Not as much as I should in this space (sorry!), but quite a bit nonetheless. WordPress is my blogging platform of choice. Mainly because it’s powerful and flexible, as well as being easy to use. Due, in large part, to my work as a technology coach, I find myself investigating other blogging platforms. Sometimes, the proofs of concept that I create for my clients wind up being going concerns. That happened with two such blogs, as well as my coaching site. They were spread across a pair of services that designed for static blogging. There was…

    Scott Nesbitt
    27 Jan 2015 | 2:34 am
    2015 is year of changes for me. The biggest change is my aim to streamline my processes, my systems, and my tools. I want to go back to basics with everything I do. That includes the Linux distro I use. While I like Lubuntu (and still recommend it), I’ve been feeling the need to go lighter. You might recall that a year or so ago, I took elementary OS for a two-week test drive. My experience was more than favourable, but as I wrote at the time: While I really like elementary OS, I see no compelling reason to switch over from Lubuntu. At least, for the moment. The moment came the weekend…

  • Android 5.1: “ignore wireless networks without internet feature” fails

    Benjamin Kerensa
    13 Mar 2015 | 9:42 pm
    Android 5.1’s new “ignore wireless networks without internet” feature (which does not have any way to be toggled off) basically disconnects from wifi networks lacking internet. This will cause major issues for tech gadgets such as the Chromecast, GoPro, Parrot’s Lineup of Drones (Bebop, ARDrone, etc). Basically all of these devices create a WiFi network that has no internet connectivity and in Android 5.1 the behavior is to automatically disconnect from these networks. I confirmed this on a Bebop and Chromecast so far as have other users. Yikes! Wonder how many months until Google…

You would think that things like good process and transparency come naturally to open source projects but the thing is, no matter how old or new the project is there are always people coming and going who have varying depths of experience in doing work in the open and as a result open is not always the default in open source projects. Most recently, I have been pushing for more transparency in some programs at Mozilla and specifically in the area that deals with…

If you want to add or remove any Nginx modules such as ngx_lua, ngx_http_secure_download_module, or nginx_uploadprogress_module you’ll either need to compile from source or find a PPA that meets your needs.

This prompts users for a username and a password before even allowing access to the admin files and WordPress authentication.

Even if your site has no sensitive information, it’s worth considering using HTTPS as Google now considers it a ranking signal.

  • How to merge or split pdf files using convert

    Peter Leung
    4 Mar 2015 | 5:30 am
    convert is a member of the ImageMagick software suite for image manipulation. Two of my earlier posts dealt with using convert to slice and resize an image. It is a lesser-known fact that convert also works with pdf files. I'd previously explained how to merge and split up pdf files using tools such as pdftk and gs. In this post, I'll illustrate how to do the same using the convert program. First, you need to install convert which is packaged in the ImageMagick suite. $ sudo apt-get install imagemagick Merging 2 pdf files (file1 and file2) into a new file (output) is as simple as executing: $…
  • How to update a MySQL table with data from itself

    27 Feb 2015 | 11:28 am
    Suppose I want to update a MySQL table with data that refers to the same table. To make it easier to follow along, I will use the following actual WordPress administration scenario. My task is to copy the attributes of a WordPress theme named decode to its child theme named decode-child. Theme attributes are stored in the MySQL table wp_options. The table has 2 relevant fields: option_name This field identifies the theme. The parent theme has the value theme_mods_decode; the child theme, theme_mods_decode-child.option_value This is the field we want to copy from the parent theme to its child.
  • What to do next after spinning up a Debian VPS

    Recently, I opened an unmanaged VPS hosting account with Digital Ocean (of which I am an affiliate), and created a barebone Debian virtual server. Because the hosting was unmanaged, I had to apply all the system changes to the machine myself. Below were the steps I took to set up the Debian virtual machine after spinning it up for the first time. I assume that you want to set up the LAMP stack - Linux, Apache, MYSQL, PHP - on your machine. SSH into the virtual machine. Before you can login, you need to know the public IP address of the new machine. Digital Ocean sends it to you in an email. $…

    If you share your Linux desktop machine with other users, you may occasionally need to switch from 1 X session to another. For example, you are busy writing code or blogging, and your spouse walks up to you and asks to 'quickly' check her email. You can log out so that she can login using her own account. But, the current context of your work is lost, and you need to re-establish it when you resume. A better way is to have her run a second simultaneous X session. The steps are as follows: Switch to a virtual terminal. By default, six virtual text terminals are available to you (Ctrl+Alt+F1 to…
