Video Tutorial: Writing code onto Micropython Wemos D1 using Ampy
February 5, 2018
Last week we covered how to flash Micropython onto an ESP8266 (Wemos D1 Mini) but we had to type our code into the REPL by hand. That’s not terribly useful for a real world project, so this week we learn how to upload code and make it run on boot. We’ll be using a tool called Ampy, by Adafruit, since the Micropython world is a little immature.
First day's results for Windows 10
July 29, 2015
Something happened So the results are in from the first day of the Windows 10 release, and they are mixed. John has gone through the the upgrade process successfully on two machines (Windows 7 Home and Windows 7 Pro). In my case I got the wonderful “Something happened” when trying to write a USB installer (from two different machines). Eventually I broke down and downloaded the Windows 10 ISO from MSDN and burned it to a USB using the Windows 7 USB/DVD tool. It annoys me a great deal when there’s an error with no diagnostics information, fortunately I could work around it.
GFI Vipre Enterprise for Mac – Run away logs
August 16, 2013
Yesterday at the office we discovered that GFI Vipre for Mac has a “small” run away logging problem. The antivirus logs to /private/var/log/vipred_stdout.log and /private/var/log/vipred_stderr.log — The latter of which being the problem file. stderr on numerous machines was in excess of several gigabytes in size. While we never bothered to correctly address the issue, Alex “fixed” it by putting a script into JAMF Casper Suite to rm the file.
OpenDNS Umbrella – Safety or Zombies?
August 8, 2013
We started evaluating OpenDNS Umbrella at the office while back. While I’ve always been a big fan of OpenDNS (and even applied to work there once), I was reluctant to get into this “Umbrella” service. Not because I fear Umbrella Corp, but because it just didn’t seem useful. What little info I skimmed on the web wasn’t exactly what one would call exciting. After taking it for a spin, I’ve found that it actually is useful, though their marketing material is convoluted.
Setting up Node.JS on OSX – Quick and Easy
July 24, 2013
Recently, I’ve gotten into learning Node.JS. Installing Node on my servers for remote development is easy enough with a wajig install nodejs, however I want to be able to work off my laptop while I’m on vacation. While it’s not quite as easy as one command, it really isn’t that hard to setup.
Securing your Apple adapters in conference rooms
February 28, 2013
Modern IT is an increasingly Mac-friendly endeavor. One of the major annoyances (in my book) with Macs is the use of adapters and dongles. It isn’t so much that adapters are required, it’s that in shared spaces (such as conference rooms) you need to have them easily accessible AND removable, but not-easily wandered off with. This last requirement is the most troublesome for me because people seem to love to go wandering off with VGA and network adapters from conference rooms. They may have dozens of the damn things back at their desk (because I readily provide them to my users), but they’ll accidentally walk off with another. I found a solution to securing all types of Apple adapters in our conference rooms, and it costs about about $0.10 USD.
Making a bootable USB drive of OS X Mountain Lion
July 25, 2012
As of this morning, OSX 10.8 “Mountain Lion” is out. It’s a whopping $19.99 on the App Store and a couple hour download (depending on your internet connection). If you’ve got multiple machines to install, or just like to be prepared, you can make a bootable USB thumb drive of Mountain Lion. It’s really easy, in fact it is the exact same process as making USB drives for 10.7.
Taking Ubuntu 12.04 Precise Pangolin for a spin
May 10, 2012
It’s been about 2 weeks since Ubuntu 12.04 (Precise Pangolin) has been released and I figured it was about time to take it for a spin. I reformatted my Dell Latitude E4200 (which was running Linux Mint 12 KDE) and installed the 64 bit desktop edition. I thought I was done with this entire Unity/Gnome 3 debacle and off to KDE forever, turns out that might have been premature.
OSX Knows Better Than You: How to change the default application for a file
August 9, 2011
In case it wasn’t obvious by the number of Apple related posts as of late, I’ve been spending almost all my time on OSX based machines. One of the things I’ve found annoying is that I couldn’t change the default file/application association, or at least I couldn’t figure it out. I watched a lot of (downloaded) videos on my computer and every single time I do so, I have to drag it down to the VLC icon in the dock. A mistaken double-click (old habits) would end with QuickTime complaining to me. Recently, I figured out how to change the default application for a file type, and I can now proudly enlighten you how to do the same.
iPad vs Windows Pad (Dell XT2)
October 8, 2010
We’re trying to standardize onto Ubuntu at work and we need hardware that works really, really well. One thing that I thought might be nice to have in the office was the Dell XT2 tablets. Not that I expect everyone to have one, but I thought there might be at least a handful of users that would appreciate them. Especially those at the office that use iPads (albeit there are only a couple). Yesterday, we got in the XT2 for evaluation and I excitedly started carrying it around with me (I’ve always, always, always wanted a tablet). I’ve not had time to put Ubuntu on the machine, but I thought that the comparison to the iPad might be interesting.
WebDAV Clients – Linux & OSX
August 25, 2010
After getting LDAP, Apache & WebDAV working together in perfect harmony, I needed to get clients accessing the “shares” I was setting up. Fortunately Linux & OSX make this extremely easy. Windows… is another story, a story which can only be told… tomorrow.
Installing & Configuring OpenDS 2.2 on Ubuntu 10.04
August 19, 2010
Recently, I’ve needed to setup an open source centralized authentication server. After research and testing some of the options, I settled on OpenDS, and while I’m leery of anything running Java, I’ll admit… OpenDS is really nice. Most importantly, getting it up and running is a piece of cake.
IPv6: Backwater hick to bleeding edge – in a weekend?!
July 14, 2010
So last week, I didn’t know a whole lot about IPv6 (backwater hick — slow and behind the times). After spending a long weekend delving into the world of it, I find out that I’m basically on the bleeding edge already… and that makes me sad. How can I go from not even having used IPv6 to the bleeding edge in a few days? As it turns out, there isn’t much of a distance to go.
