10 Ιουλίου 20 04:00 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
Was just trying to make a Python 2 script work in Python 3 and at first it seemed I just needed a small change to add missing parentheses to the argument of a couple of print statements. But then another issue came up, it wasn’t understanding the command raw_input(somePrompt) that was occuring at various places […]

14 Απριλίου 20 10:28 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
If you’re having issues with your Windows 7 or newer, you should consider whether its installation has become corrupted (due to malicious software or hard drive errors). After doing a disk check (say by right clicking the appropriate drive under my computer and selecting Properties, then Tools tab and Error checking) and a complete virus […]

A friend sent me the other day a screenshot from the installer of Microwords Pro Greek version on Windows 10 that was showing gibberish instead of Greek. At their school on Windows 10 it was showing up fine, so they wondered what the issue was. They mentioned that on Windows 10 english it was showing […]

Fix: make ownCloud installer display in English language
26 Μαρτίου 20 02:33 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
OwnCloud is an interesting solution for setting up a file sharing cloud for a group of people. However,one issue I’ve found with its Windows desktop client’s current version (which looks clean of any viruses since I always check first) is that if your Windows 10 is configured with a preferred language that the desktop client’s […]

Fix: Buildbox activation issues on load
22 Φεβρουαρίου 20 09:51 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
Buildbox is a wonderful game authoring tool (that spans the whole nocode-code continuum, including the low-code aspect). It now has a free version too with nice templates and tutorials included. I had an issue with the Windows version (it also has an indentical MacOS-X version since it’s a Qt-based app) where it was complaining about […]

Fix: Acer Aspire One (AS1) ZG5 blank screen at startup
22 Δεκεμβρίου 19 02:15 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
Seems Acer Aspire One (AS1) ZG5 can have a recurring problem, esp. if its battery is near its end of life. If it shuts down abruptly its BIOS settings seem to get corrupted and its BIOS instead of discarding them seems to freeze. Luckily they have a way to update the BIOS via USB key […]

After upgrading from Visual Studio 2017 to Visual Studio 2019 I was able to update NuGet packages Fody and Costura.Fody of a solution that needed them (to package assembly DLLs inside console EXEcutables) and the solution was rebuilding fine. However after I synced the solution via a Git repository on another machine and installed the […]

For some time now I was trying to update the BIOS of an older Dell Inspiron 3537 laptop from inside Windows (with the InsydeFlash application that the respective Dell update package employs), only to get a blue screen saying Invalid Firmware Image upon reboot and the BIOS update was skipped every time. Since that update […]

11 Ιουνίου 19 09:31 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
OpenLayers is a fine alternative to the map visualization part of Google Maps Platform, however many of its examples sometimes use features from future and server-side Javascript versions, like “imports”. Based on lou’s answer at https://stackoverflow.com/questions/51093964/why-examples-dont-work-a-struggle-with-imports/56549364, here’s a fix I just did to make the Marker animation example work when you just copy-paste the example […]

Fix: Word print view showing no margins and pages appear collated

I’m often asked by friends and family to assist them on frustrating technical issues they can’t resolve by themselves. Thanks to remote access / support software like TeamViewer, this is a piece of cake nowadays. The solution to such problems isn’t always straightforward though. Just came across a Microsoft Word installation where suddenly the Print […]

Had just converted to target .NET framework 4.7.2 a Visual Studio solution full of 4.5 libraries, console apps and an MVC 5.0 (recently converted from 4.0) web app and all seemed to build fine, but then noticed that with web.config of the MVC web app open in the editor, it was showing lots of warnings […]

Fix: jqGrid search operator menu items jumping around on hover

A colleague noticed earlier on today, that on the Chrome browser they were using, the search operator menu items of a jqGrid on a web app’s UI were jumping around on hover, making it practically impossible to select one.    Seems this had started occurring on that ASP.net MVC web application, after a recent update […]

HowTo: Fix DVD/CD with Live filesystem (Packet/UDF) on Windows
10 Οκτωβρίου 18 09:33 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
The other day I found how easy it is to use a Live CD/DVD (where packet writing occurs when adding stuff) instead of a Mastered one (where all is kept to be written when you close the disk) on Windows. It feels more like using a USB flash disk and should be more safe regarding […]

Fix: jQuery’s jqGrid search UI custom styling
03 Οκτωβρίου 18 01:35 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
Lately, I’ve got the task of maintaining/extending an ASP.net MVC web application that is using jQuery’s jqGrid for data grids on its UI. First thing I noticed was how confusing the search UI on the grid’s header was: Those symbols on the left-side of each column’s searchbox are for the type of search (e.g. contains, […]

Fix: Windows 10 laptops with AMD graphics adapter going really slow
27 Ιουνίου 18 07:11 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
Quoting my comment from a discussion thread on the AMD Community website Actually the drivers back from 2015 that Microsoft serves for AMD laptop graphics adapters seem to make Windows 10 crawl (at everything, not just in graphics stuff). Installing the newest ones from AMD (in this case the beta driver) makes laptops work decently […]

HowTo: Install Skype desktop on Windows 10 (for older webcams)
22 Μαρτίου 18 02:05 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   
On Windows 10, Microsoft (they’ve acquired Skype some years ago) provide a Windows Store app for Skype, however Universal Windows Platform (UWP) apps like that one don’t support older webcams (even the ones embedded in not-that-old laptops). Unfortunately, Microsoft hasn’t bothered to provide some frame grabber driver to bridge with DirectShow-based etc. older webcams that […]

For some time now, I was getting very annoyed while copy-pasting content from other software into Microsoft Word 2010. I would press CTRL+C at some other software and then would press ALT+TAB to go into an open Word document and press CTRL+V to paste, but it would not. So I had to move my fingers […]

Fix: VSIX installer error – SignatureDescription could not be created

This is my answer at: http://stackoverflow.com/questions/31552082/vsix-installer-signaturedescription-could-not-be-created-for-the-signature-algo/ to the question on why some extensions fail to install at RC (Release Candidate) versions of Visual Studio 2015, showing error “SignatureDescription could not be created for the signature algorithm supplied”.
