I have had some annoying problems in recent months with my work laptop refusing to connect to certain WiFi login pages (more technically known as Captive Portals), essentially locking me out of the WiFi in certain places. Here is how I solved it.Continue reading “Failing to See WiFi Login Page [Captive Portal] / Solved”
For some reason, Microsoft has decided to hide some decidedly useful features in Windows 10 explorer behind the non-intuitive and rather unknown “shift-key + right-click” combination.Continue reading “Off-Topic: Windows Explorer Tip: Shift Right-Click”
Late last year I was trying to do some machine learning work on my brand new Alienware 15 R4 gaming laptop. I had bought the laptop in order to have something portable with sufficient performance to actually do convolutional neural network (CNN) training and inference “on the road”. The GTX 1060 in the laptop is just as powerful as my home desktop machine, and should run Tensorflow and Keras well. I had the setup working on the desktop already, and copied the code over to the laptop. When trying to run the code the first time, I got some rather strange errors that I finally figured out meant that I was missing the CUDA toolkit. I downloaded CUDA version 10, installed, and the machine rebooted into the Windows 10 automatic repair mode.Continue reading “Windows 10 Reboot Loop – CUDA & Alienware”
I recently asked myself the question of just how many Powerpoint files I had on my work laptop and on my home machines. It turns out that it was pretty easy to figure that out using Windows Powershell, with some commands I found on a random website.
In a previous Intel blog post “Question: Does Software Actually Use New Instruction Sets?” I looked at the kinds of instructions used by few different Linux setups, and how each setup was affected by changing the type of the processor it was running on (comparing Nehalem to Skylake). As a follow-up to that post, I have now done the same for Microsoft* Windows* 10. In the blog post, I take a look at how Windows 10 behaves across processor generations, and how its behavior compares to Ubuntu* 16 (they are actually pretty similar in philosophy).
The new Windows 10 Controlled Folder Access (CFA) feature is a great idea – prevent unknown programs from modifying your files, to stop ransomware in its tracks. It is so good that I forced an early update to Windows 10 Build 1709 (“Fall Creators Update”) on a couple of my home machines and enabled it. Now, I have quickly disabled it, as it is not possible to actually use it in a real environment. It just stops things a bit too hard.
A blog post from Undo Software informed me that Microsoft has rather quietly released a reverse debugger tool for Windows programs – WinDbg with Time Travel Debug. It is available in the latest preview of WinDbg, as available through the Windows Store, for the most recent Windows 10 versions (Anniversary update or later). According to a CPPcon talk about the tool (Youtube recording of the talk) the technology has a decade-long history internally at Microsoft, but is only now being released to the public after a few years of development. So it is a new old thing 🙂
Now that Windows 10 has been officially out for a while, I decided to give it a try on one of my home machines. I expect that all my Windows 8.1 machines will be updated eventually – it is a free update, after all, and supposedly things should work just as well as in Windows 8.1. Just with a different user interface. Windows 10 is indeed different from Windows 8.1 in fairly significant ways, and it really feels like what would have come after Windows 7 if Windows 8 hadn’t come between. I can see why many or even most people see this as the better upgrade path, even if I lament some of the changes made.
