    I’ve been interested in building a radar system for a while now. I’ve been following the development of the RTL-SDR for a while, and I’ve been wanting to build a system that uses it. I’ve also been wanting to build a web app that uses WebUSB to communicate with a USB device. So I decided to combine the two and build a web app that uses a RTL-SDR to display aircraft on a map.

I might be understating it a bit, but WebGL is a big deal. You only need to spend five minutes on one of the many design awards sites to see site-after-site fully leaning into the power of canvas. Tools like threejs bring the power of 3D and GLSL shaders to the browser and, with that, a whole new level of visual effects.

Visual Studio DTE in Powershell​

Control Visual Studio from Powershell using the DTE (Development Tools Environment) COM Object.

I found a simple answer by playing with the idea in ISE for a little while.

Basically, the call to GetActiveObject returns a COM object, which can be used directly in PowerShell. After executing LoadDTELibs, you can get an instance of DTE by calling GetActiveObject and then refer to the result directly.

So...
PS> $dte = [System.Runtime.InteropServices.Marshal]::GetActiveObject("VisualStudio.DTE.11.0")
PS> $dte = [System.Runtime.InteropServices.Marshal]::GetActiveObject("VisualStudio.DTE")
PS> $dte.solution.Create("D:\Testing", "Acme.sln")
PS> $dte.solution.SaveAs("D:\Testing\Acme.sln")
Get-ChildItem HKLM:\Software\Classes -ErrorAction SilentlyContinue | Where-Object {
    $_.PSChildName -match '^\w+\.\w+$' -and (Test-Path -Path "$($_.PSPath)\CLSID")
} | Select-Object -ExpandProperty PSChildName
Sub DTEExample()
    Dim objTextDoc As TextDocument
    Dim objEP As EditPoint

    ' Create a new text document.
    DTE.ItemOperations.NewFile("General\Text File")
    ' Get a handle to the new document.
    Set objTextDoc = DTE.ActiveDocument.Object("TextDocument")
    Set objEP = objTextDoc.StartPoint.CreateEditPoint
    ' Create an EditPoint and add some text.
    objEP.Insert "A test sentence."

This invention is important for the large-scale synthesis of fertilizers and explosives. It is estimated that two thirds of annual global food production uses ammonia from the Haber–Bosch process, and that this supports nearly half the world population. Oh shit...

  • 2022-07-03 How Certificates Work: Public Key; Security Services Microsoft Docs

    Digital certificates are electronic credentials that are used to assert the online identities of individuals, computers, and other entities on a network. Digital certificates function similarly to identification cards such as passports and drivers licenses. They are issued by certification authorities (CAs) that must validate the identity of the certificate-holder both before the certificate is issued and when the certificate is used. Common uses include business scenarios requiring authentication, encryption, and digital signing.

  • 2022-07-03 Cryptography - Win32 apps Microsoft Docs

Despite the vampires' vulnerability to sunlight, and all of mankind's technological advances, the vampires' greater strength and speed made them impossible to defeat until humanity sheltered them in giant walled cities and trained a group of elite warriors, the Priests, which turned the tide.

  • 2022-04-17 What Does "Shitty Job" Mean in The Low-Skill, Low-Pay World?

    There’s all sorts of terms and experiences I’m sure I could apply this to, but right now the one that interests me most is the phrase a shitty job. I recently transitioned from having lived my whole life doing the kind of jobs you could do with zero day’s training and no developed skills. I’ve heard the phrase (and some classier high-end equivalents) since then, but it’s used much differently; it’s describing a different set of worries as experienced by a different kind of person living a different sort of life. The Author - Resident Contrarian on Substack - writes about different kinds of people issues.

Good old reads​

Because of that I usually make all my services and systems crash only. End up using things like use atomic file moves, open files with append-only, use kill -9 to stop services and so on. To make your system crash-onl,y you have to go down the base system calls.
Some observed effects so far (many are covered in the article):
* Faster restarts (if your regular operation involves restarting lots of processes).
* Less code (don't have to handle both the clean shutdown and dirty shutdown).
* Recovery/cleanup code if it is needed, is often ends up moved to startup instead of shutdown (you might have to recover corrupt files when you start up again. For example re-truncate the files to a known offset based on some index).
* Something else might need to manage external resources (OS IPC resources, shared memory, IPC message queues etc). This could be a supervisor process.
* If you do a lot of socket operations on localhost, your sockets could get stuck in TIME_WAIT state and you'll eventually run out of ephemeral ports if you do a lot of restarts (say during testing). SIGTERM signals often are caught and processes (libraries) perform a cleaner shutdown.
* Think very well about the database you use and see if it can can support crash only operation. Some do some don't ( I won't name any names here ).

    In a recent post, Parrhesia suggested that course grades should be 100% determined by performance on a final exam—an exam that could be taken repeatedly, with the last attempt being the course grade. (See also the discussion at r/slatestarcodex.) The idea is that grades are supposed to measure what you know, and if you do well on a final, then you know the material. Ha. Haha. Hahahahahahahaha.

    Zillow made news last week as it reported a loss of $881 million on its house-buying business last year⁠. That’s especially remarkable because house prices rose dramatically for much of the year. Naturally, this got me thinking about fantasy football. I’ll get to that later. But first, let’s back up and talk about what the business idea⁠—often called iBuying⁠—is actually about.

  • 2022-03-10 8 Techniques to Avoid GC Pressure and Improve Performance in C# .NET - Michael's Coding Spot

    .NET provides a lot of great collections types like List<T>, Dictionary<T>, and HashSet<T>. All those collections have dynamic size capacity. That means they automatically expand in size as you add more items.

    - Set initial capacity for dynamic collections
    - Use ArrayPool for short-lived large arrays
    - Use Structs instead of Classes (sometimes)
    - Avoid Finalizers
    - Use StackAlloc for short-lived array allocations
    - Use StringBuilder, but not always
    - Use String Interning in very specific cases
    - Avoid memory leaks
    - Summary:
        - Allocations should be avoided if possible.
        - Reusing memory is better than allocating new memory.
        - Allocating on the Stack is faster than allocating on the Heap.

In the entertainment world, there’s a long lineage of comedians who tried to copy each other, failed, and became great themselves: Johnny Carson tried to copy Jack Benny, but failed and won six Emmy awards. Then, David Letterman tried to copy Johnny Carson, but failed and became one of America’s great television hosts.

This heuristic is right 99.9% of the time, but it provides literally no value. When all the Brier scores are calculated, he is the best futurist of all. His heuristic is truly superb.

    One of the skills I wish I'd learned earlier in my career is basic Linux server administration. Specifically in relation to hosting something on the web, either a web app or API that I wrote myself, or something from the thriving self-hosted community, such as Wordpress. Managing servers is increasingly seen as the 'older way' of doing things, so it's easy to become a software developer and never learn to set up a VPS, set up remote access, stand up a firewall, etc.

So naturally, as an entrepreneur with full autonomy over my own schedule, I've applied gamification principles to innovate my own work schedule from the ground up rather than lazily adopting norms from the 9-to-5 world.

  • 2022-01-28 Feature Flags Feature Flags allow you to safely deploy and roll back new features. It means you can deploy features and then slowly roll them out to your users. If something has gone wrong, you can roll back new features without having to re-deploy your application. Feature Flags can also help you control access to certain features in your product (e.g. only show paid features to users with an active subscription).

  • 2022-02-08 Gyroflow

    Gyroflow is an application that can stabilize your video by using motion data from a gyroscope and optionally an accelerometer. Modern cameras record that data internally (GoPro, Sony, Insta360 etc), and this application stabilizes the captured footage precisely by using them. It can also use gyro data from an external source (eg. from Betaflight blackbox). Github: gyroflow/gyroflow: Video stabilization using gyroscope data
