So this is interesting: Normally a Windows program (executable) if you try to run it anywhere else will show a message “cannot be run here” and terminates.
Printing this message is actually done by a little program whos task is to only print out this very message. So it can be overwritten.
Michael Strehovský did exactly this, very impressively. He documented what he did to get the game “snake”, written in C#, running on DOS instead of the “does not run here” stub. In an executable file that would run both, on standard 90s MS-DOS as well as on Windows with the .NET Framework installed.
He used a quite elaborate toolchain – namely DOS64-stub.
You can read all of this in the full thread. I recommend a deeper dive, as it’s a great start to better understand the inner workings of your computer…
When you own a recent iOS device (iOS 11 and up) you’ve got the choice between “High Efficiency” or “Most Compatible” as the format all pictures are being stored by the camera app.
Most Compatible being the JPEG format that is widely used around the internet and other cameras out there and the “High Efficiency” coming from the introduction of a new file format and compression/reduction algorithms.
A pointer to more information about the format:
High Efficiency Image File Format (HEIF), also known as High Efficiency Image Coding (HEIC), is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12 (ISO/IEC 23008-12). The MPEG group claims that twice as much information can be stored in a HEIF image as in a JPEG image of the same size, resulting in a better quality image. HEIF also supports animation, and is capable of storing more information than an animated GIF at a small fraction of the size.
As Apple is aware this new format is not compatible with any existing tool chain to work with pictures from cameras. So you would either need new, upgraded tools (the Apple-way) or you would need to convert your images to the “older” – not-so-efficient JPEG format.
RTL-SDR is a very cheap ~$25 USB dongle that can be used as a computer based radio scanner for receiving live radio signals in your area (no internet required). Depending on the particular model it could receive frequencies from 500 kHz up to 1.75 GHz. Most software for the RTL-SDR is also community developed, and provided free of charge.
The origins of RTL-SDR stem from mass produced DVB-T TV tuner dongles that were based on the RTL2832U chipset. With the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) it was found that the raw I/Q data on the RTL2832U chipset could be accessed directly, which allowed the DVB-T TV tuner to be converted into a wideband software defined radio via a custom software driver developed by Steve Markgraf. If you’ve ever enjoyed the RTL-SDR project please consider donating to Osmocom via Open Collective as they are the ones who developed the drivers and brought RTL-SDR to life.
If you, like me, once every while need to type the same again and again it might also get tired for you as it got for me.
A specific example: I very frequently need to have the current date available to be entered.
May it be because I need to name a file correctly, prepending it with the current date, or because I need it to refer to a specific date in a text I am currently typing.
The common scheme for dates I am using is YYYY-MM-DD. The 24th of September 2019 becomes 2019-09-24.
For when I am on Windows I am using a small utility called “TyperTask” to have a system wide shortcut available to me that will enter the current date with the press of a button.
As you can see in the screenshot above. By simply adding / editing the TXT file you will be able to specify new shortcuts. In the above case ALT+D or STRG+SHIFT+D will generated my desired date text pattern.
XamariNES is a cross-platform Nintendo Emulator using .Net Standard written in C#. This project started initially as a nighits/weekend project of mine to better understand the MOS 6502 processor in the original Nintendo Entertainment System. The CPU itself didn’t take long working on it a couple hours here and there. I decided once the CPU was completed, how hard could it be just to take it to next step and do the PPU? Here we are a year later and I finally think I have the PPU in a semi-working state.
If you ever wanted to start looking at and understand emulation this might be a starting point for you. With the high-level C# being used to describe and implement actual existing hardware – like the NES CPU:
The author does the full circle and everything you’d expect from a simple working emulator is there:
I am using 1Password for years now. It’s a great tool. So far.
As I am using it locally synced across my own infrastructure I feel like I am getting slowly but surely pushed out of their target-customer group. What does that mean?
The current pricing scheme, if you buy new, for 1Password looks like this:
So it’s always going to be a subscription if you want to start with it and if you want it in a straight line.
It used to be a one-time purchase per platform and you could set-up syncing across other cloud services as you saw fit. If you really start from scratch the 1Password apps still give you the option to create and sync locally but the direction is set and clear: they want you to sign up to a subscription.
I am not going to purchase a subscription. With some searching I found a software which is extremely similar to 1Password and fully featured. And is available as 1-time purchase per platform for all platforms I am using.
Also. This one is the first that could import my 1Password export files straight away without any issues. Even One-Time-Passwords (OTP) worked immediately.
The name is Enpass and it’s available for Mac, Windows, Linux, iOS, Android and basically acts as a step in replacement for 1Password. It directly imports what 1Password is exporting. And its pricing is:
Subscriptions for services as this are a no-go for me. It’s a commodity service which I am willing to pay for trailing updates and maintenance every year or so in a major update.
I am not willing to pay a substantial amount of money per user per month to just keep having access to my Passwords. And having them synced onto some companies infrastructure does not make this deal sweeter.
Enpass on the other hand comes with peace-of-mind that no data leaves your infrastructure and that you can get the data in and out any time.
It can import from these:
As mentioned I’ve migrated from 1Password in the mere of minutes and was able to plug-in-replace it immediately.
Mass storage hardware breaks all the time. Sometimes it’s hardware that breaks, but sometimes it’s the software that breaks. If it’s the software (or own talent) that made the data go boom, TestDisk is a tool you should know about.
DISCLAIMER: If the data you are trying so recover is actually worth anything you might want to reserve to a professional data recovery service rather than trying to train-on-the-job.
TestDisk is powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable againwhen these symptoms are caused by faulty software: certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.
Fix partition table, recover deleted partition
Recover FAT32 boot sector from its backup
Rebuild FAT12/FAT16/FAT32 boot sector
Fix FAT tables
Rebuild NTFS boot sector
Recover NTFS boot sector from its backup
Fix MFT using MFT mirror
Locate ext2/ext3/ext4 Backup SuperBlock
Undelete files from FAT, exFAT, NTFS and ext2 filesystem
Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions.
TestDisk has features for both novices and experts. For those who know little or nothing about data recovery techniques, TestDisk can be used to collect detailed information about a non-booting drive which can then be sent to a tech for further analysis. Those more familiar with such procedures should find TestDisk a handy tool in performing onsite recovery.
And if you give up, think about writing an article of you actually digging deeper:
The Android tablets I am using for my kitchen scale display and for myfitnesspal data-entry are aging quite bad and apart from the near-display death of one of the tablets both are not supported and updated anymore.
Using them therefore poses an increasing risk. After one of them almost died on me I was determined to replace them both. Looking at alternatives at the lowest possible price quickly showed that I am not going to get another Android tablet.
Instead I was ready to give a chinese company a chance:
I ordered it on 24th of June and it was delivered today. All in all I’ve paid 136 Euro for the tablet and 45 Euro for the keyboard attachement.
Despite the ridiculously low price this thing is quite impressive. It’s sporting a fast-enough Intel Atom processor with 1.4 ghz and 4 Gbyte of RAM. The 64 Gb of solid-state storage where quickly upgraded by an additional 400 Gb MicroSD card for local data storage.
As of writing this it’s still installing and updating the Windows 10 to 1903 but so far I am beyond impressed.
I’ll write more about the device when I’ve had more time to use it. One word for the keyboard attachement: the keyboard is good-enough. Not great but better than for example that on the Pinebook. The touchpad is very small but works – the thing has a Touchscreen anyway.
The first device in my household recently has updated itself to the newest Windows 10 1903 build.
On the very first moment of the login screen appearing and logging in I could tell that I hate one specific change that has made it into this latest update.
And it’s the default mouse cursor.
Back in the Pre-Windows Vista days, when I used to work for Microsoft, I was using the latest internal build of Windows and just around the first RTM (release-to-manufacture) build they touched up on the final designs.
I remember vividly when the mouse cursor had changed from the one we new and used since Windows 3 to a shorter tailed more “high-def” looking one.
Since then there were a couple of changes on the cursor but the general design was kept.
Now apparently with the latest Windows 10 update from 1803 to 1903 I got a new – old default mouse cursor.
By reflex I changed it back to the one I love and stored safely in a backup. I cannot stand the long tail and the weird pixel-ness of the cursor. It just looks kinda weird to my eyes.
