Finally Run Useful Apps On A Windows Phone

September 26, 2019 by Bryan Cockfield 30 Comments

Not every piece of technology or software can succeed, even with virtually unlimited funding and marketing. About the same number of people are still playing Virtual Boys as are using Google Plus, for example. In recent memory, the Windows Phone occupies the same space as these infamous failures, potentially because it was late to the smartphone game but primarily because no one wanted to develop software for it. But now, you can run Android apps on Windows Phones now. (Google Translate from German)

To be clear, this doesn’t support all Android apps or all Windows Phones, and it will take a little bit of work to get it set up at all. But if you still have one laying around you might want to go grab it. First you’ll need to unlock the phone, and then begin sending a long string of commands to the device which sends the required software to the device. If that works, you can begin loading Android apps on the phone via a USB connection to a PC.

This hack came to us via Windows Central and Reddit. It seems long and involved but if you have any experience with a command line you should be fine. It’s an interesting way to get some more use out of your old Windows Phone if it’s just gathering dust in a closet somewhere. If not, don’t worry; Windows Phones were rare even when they were at their most popular. We could only find one project in our archives that uses one, and that was from 2013.

Windows 10 Goes To Shell

June 10, 2019 by Al Williams 51 Comments

Windows 10 — the operating system people love to hate or hate to love. Even if you’re a Linux die-hard, it is a fair bet that your workplace uses it and that you have friends and family members that need help forcing you to use Windows at least some times. If you prefer a command line — or even just find a place where you have to use the command line, you might find the classic Windows shell a bit anemic. Some of that’s the shell’s fault, but some of it is the Windows console which is — sort of — the terminal program that runs various Windows text-based programs. If you have the creator update channel on Windows 10, though, there have been some recent improvements to the console and the Linux system that will eventually trickle down to the mainstream users.

What’s New?

So what’s new? According to Microsoft, they’ve improved the call interface to make the following things work correctly (along with “many others”):

Core tools: apt, sed, grep, awk, top, tmux, ssh, scp, etc.
Shells: Bash, zsh, fish, etc.
Dev tools: vim, emacs, nano, git, gdb, etc.
Languages & platforms: Node.js & npm, Ruby & Gems, Java & Maven, Python & Pip, C/C++, C# &
.NET Core & Nuget, Go, Rust, Haskell, Elixir/Erlang, etc.
Systems & Services: sshd, Apache, lighttpd, nginx, MySQL, PostgreSQL

The changes to the console are mostly surrounding escape sequences, colors, and mouse support. The API changes included things like allowing certain non-administrative users to create symlinks. We’ve made X Windows work with Windows (using a third-party X server) and Microsoft acknowledges that it has been done. However, they still don’t support it officially.

Windows Utility Helps ID Serial Ports

May 22, 2019 by Lewin Day 49 Comments

The humble serial interface has been around for a very long time, and will stay with us in one form or other for the foreseeable future. It was easy enough to keep track of back in the days when a computer only had one, or perhaps two COM ports. However, in this day and age of USB-programmable microcontrollers, it’s likely you’ve got COMs coming out the wazoo. Thankfully, [Amr Bekhit] has put together a utility to help solve this problem.

[Amr’s] utility is called Serial Port Monitor, and it does what it says on the tin. When new serial ports are enumerated in Device Manager, a system tray notification pops up noting the number of the newly attached COM port. Additionally, it maintains a list of ports sorted in order of the newest first, and also features a right-click menu that allows the launching of various terminal programs.

It’s a useful tool to keep in your back pocket that can prove particularly so when programming many devboards at once, or any other time when you find yourself dealing with a mess of serial devices.

Incidentally, if you find yourself having continual headaches with USB-to-Serial adapters on Windows, this might just be your problem. Happy hacking.

Footnote: In light of this article, the author would like to formally apologise to [Cosmos2000] for permanently disabling COM1 on his main programming rig. Sorry, friend.

Finally, An Open Source Calculator

March 12, 2019 by Brian Benchoff 104 Comments

Microsoft has released the code for the Calculator app. This move is the latest in Microsoft’s efforts to capitalize on the Open Source community. Previous efforts have been the Open Sourcing of an extremely old version of DOS, and shoehorning Linux into Windows somehow in a way that’s marginally more user-friendly than spinning up a VM or popping over to your Linux partition. Oh yeah, Microsoft bought Github. Can’t forget that.

The release of the code for the Calculator app means now you too can truly verify all your calculations are correct. To build the Calculator app, you’ll need a Windows 10 computer and Visual Studio. You might think that this is the same code that’s been shipping for 30 years — it’s a simple calculator, right? Not so: the Calculator for Windows 8 had a strange and odd bug where the square root of 4, minus two, did not equal zero. Floating point is hard, kids.

Of special interest to the community, it’s now possible to disable telemetry sent from the Calculator app to Microsoft servers. Yes, the Calculator app knows you forgot how to divide, and wow man, six times nine, you needed help with that? Fortunately, telemetry can be disabled in developer’s builds by disabling the SEND_TELEMETRY build flag. Now Microsoft won’t know you don’t do math so good.

At the time of this writing, we could not be bothered to contact Microsoft to find out when the pinball game or Ski Free will be updated and Open Sourced.

Linux Fu: Turn A Web App Into A Full Program

December 5, 2018 by Al Williams 68 Comments

I hate to admit it. I don’t really use Linux on my desktop anymore. Well, technically I do. I boot into Linux. Then I do about 95% of my work in Chrome. About the only native applications I use anymore are development tools, the shell, emacs, and GIMP. If I really wanted to, I could probably find replacements for nearly all of those that run in the browser. I don’t use it, but there’s even an ssh client in the browser. Mail client? Gmail. Blogging? WordPress. Notes? OneNote or Evernote. Wouldn’t it be great to run those as actual applications instead of tabs in a browser? You can and I’ll show you how.

Having apps inside Chrome can be a real problem. I wind up with dozens of tabs open — I’m bad about that anyway. Restarting chrome is a nightmare as it struggles to load 100 tabs all at once. (Related tip: Go to chrome://flags and turn “Offline Auto-Reload Mode” off and “Only Auto-Reload Visible Tabs” on.) I also waste a lot of time searching since I try to organize tabs by window. So I have to find the window that has, say, Gmail in it and then find Gmail among the twenty or so tabs in that window.

What I want is a way to wrap web applications in their own window so that they’d show up in the task bar with their own icon, but external web pages that open from these apps ought to open in Chrome rather than in the same window. If applications were outside of the single browser window, I could move them to different desktops and organize them like they were any other program, including adding them to a launcher. Hopefully, this would let me have fewer windows like this:

The Eric Lundgren Story: When Free Isn’t Free

May 14, 2018 by Tom Nardi 197 Comments

At this point, you’ve almost certainly heard the tale of Eric Lundgren, the electronics recycler who is now looking at spending 15 months in prison because he was duplicating freely available Windows restore discs. Of no use to anyone who doesn’t already have a licensed copy of Windows, these restore discs have little to no monetary value. In fact, as an individual, you couldn’t buy one at retail if you wanted to. The duplication of these discs would therefore seem to be a victimless crime.

Especially when you hear what Eric wanted to do with these discs. To help extend the functional lifespan of older computers, he intended on providing these discs at low cost to those looking to refurbish Windows computers. After each machine had its operating system reinstalled, the disc would go along with the computer in hopes the new owner would be able to utilize it themselves down the road.

It all sounds innocent enough, even honorable. But a quick glance at Microsoft’s licensing arrangement is all you need to know the whole scheme runs afoul of how the Redmond giant wants their operating system installed and maintained. It may be a hard pill to swallow, but when Eric Lundgren decided to use Microsoft’s product he agreed to play by their rules. Unfortunately for him, he lost.

Getting A Handle On Meltdown Update Impact, Stay Tuned For Spectre

January 9, 2018 by Roger Cheng 31 Comments

When news broke on Meltdown and Spectre ahead of the original disclosure plan, word spread like wildfire and it was hard to separate fact from speculation. One commonly repeated claim was that the fix would slow down computers by up to 30% for some workloads. A report released by Microsoft today says that “average users” with post-2015 hardware won’t notice the difference. Without getting into specific numbers, they mention that they expect folks running pre-2015 hardware to experience noticeable slowdowns with the patches applied.

The impact from Meltdown updates are easier to categorize: they slow down the transition from an user’s application level code to system level kernel code. The good news: such transitions were already a performance killjoy before Meltdown came along. There exists an extensive collection of tools (design patterns, libraries, and APIs) to help software developers reduce the number of user-kernel transitions.

Performance sensitive code that were already written to minimize kernel transitions will suffer very little from Meltdown updates. This includes most games and mainstream applications. The updates will have a greater impact on the minority of applications that frequently jump between kernel and user worlds. Antivirus software (with their own problems) have reasons to do so, and probably will end up causing most of the slowdowns seen by normal users.

Servers, with their extensive disk and networking IO — and thus kernel usage — are going to have a much worse time, even as seen through Microsoft’s rosy spectacles. So much so that Microsoft is recommending that admins “balance the security versus performance tradeoff for your environment”.

The impact from Spectre updates are harder to pin down. Speculative execution and caching are too important in modern CPUs to “just” turn off. The fixes will be more complex and we’ll have to wait for them to roll out (bumps and all) before we have a better picture.

The effects might end up being negligible as some tech titans are currently saying, and that probably will fit your experience, unless you’re running a server farm. But even if they’re wrong, you’ll still be comfortably faster than an Intel 486 or a Raspberry Pi.

Do any of you have numbers yet?
