  • which diff tool do you use?
    J John Stewien

    WinMerge, does diff, 3 way merge, and can do a split view of a single file conflict that's spat out from git

  • repair or replace?
    J John Stewien

    If you are going to replace I can recommend importing an AMD Ryzen 4750G from South Korea. This CPU includes a good built in GPU, as GPUs are hard to come by right now. I found some at this eBay store https://www.ebay.com/str/beyondtheworld

  • AMD Ryzen and heat
    J John Stewien

    Looking at this page on Tom's Hardware for your CPU [AMD Ryzen 7 4750G Boost, Thermals, Overclocking, Power Consumption](https://www.tomshardware.com/reviews/amd-ryzen-7-pro-4750g-renoir-review/2) it appears that 65C max is the norm.

  • AMD Ryzen and heat
    J John Stewien

    Ryzen is spec'd to 95C. However standard practice for silicon is 65C if you want it to last. The lifetime vs heat is not a linear curve, you can kill a chip very quickly as you approach 125C.

  • Microsoft thinks my time is worthless.
    J John Stewien

    I have an offline installer that I update in the background while I'm working. And then do the update in my own time after it has downloaded. Instructions are here: [Create an offline installation - Visual Studio](https://docs.microsoft.com/en-us/visualstudio/install/create-an-offline-installation-of-visual-studio?view=vs-2019)

    The Win UI / UWP controls perform better than the corresponding WPF controls (says MS).

    I wonder how much faster? Because WPF is appalling for adding lots of objects to a parent control, as can be seen at the beginning of the following video: [My new DynamicDataDisplay.Reloaded project - YouTube](https://www.youtube.com/watch?v=c7qLWb2EHGI&t=21s)

  • Thinking of building a new desktop computer for my work
    J John Stewien

    I just got delivery of some parts to do my next budget build: CPU+GPU - AMD Ryzen 7 Pro 4750G, the G version has the GPU built into the CPU, did this because GPUs are very expensive right now. This is a nice CPU, but you have to order it from South Korea because it's OEM only. Motherboard - MSI A520M-A Pro, this board specifically supports the above CPU, has HDMI and DVI out on the board, and is low cost. I've had good experiences with MSI. Boards don't fail after 5 years like some other brands I've had. The A520M Pro (no -A) has HDMI and Display Port out on the back, but Display port cables cost extra. RAM - 16GB Crucial Ballistix DDR4-3200 16GB kit (2x8GB), "Engineered for the latest AMD platform" SDD - Crucial P2 NVMe M2 1TB, it also comes in 2TB form. P2 is more reliable than the P1, but I've only got good things to say about Crucial in general. Case - Thermaltake Versa H15 with 450W power supply, more than enough power for this build. I have 3 of these cases already, this makes the 4th, good for a neat build. Front panel ports are on top so you don't knock USB or audio peripherals out when you walk past. 2 x 32" 2560 x 1440 monitor with a BOE IPS panel (various brands, I have a Kogan). I love these BOE panels, great color, nice even brightness, supports freesync, and I run at 125% desktop scaling so everything is big and smooth, just the way my old eyes like it. I haven't built it yet, I'm expecting it to be flawless.

  • I'd like to ask a question about JSON to get a feel for priorities of coders here
    J John Stewien

    Some people have to work on air gap networks, where you can not copy anything to the network. It comes configured with a couple of approved things like the operating system, and whatever comes bundled with say Visual Studio 2015, and that's it. Nothing else gets in. With good reason too, e.g. see supply chain poisoning like the recent SolarWinds incident.

    All features should be on a different branch. If you are getting lots of conflicts then I have to wonder about your project architecture. Are you using something like PrismLibrary to separate out your modules?

  • Anyone here actually care about Windows 8 and silverlight / wpf / jupiter controversy?
    J John Stewien

    Yes I'm waiting eagerly to find out what GUI framework I'm going to be code against next. I'm programmer support in prototyping / research type area. So the useful lifetime of the apps I write isn't alway that long. Most of the code I write though is the logic and data handling code with a well defined interface for the GUI side of things to use. Changing the GUI framework to something else isn't really too big of task - designing the look and feel is the hardest bit, coding it is nothing.

  • WPF Performance
    J John Stewien

    "WPF Performance" vote +1 for oxymoron of the month. Joking aside, yes it does have some performance issues in parts. If you want speed try using Direct2D, if you want databinding and a comprehensive UI library use WPF. If you want to use a light C# wrapper around the old Win32 stuff, use Winforms. Maybe next months Build conference will offer up a new choice.

  • Why is VB being forsaken?
    J John Stewien

    It's a transform language, it transforms tables of data into other tables of data. Queries can be optimised, there are various key words for performing different functions, there's maths, filtering, and formatting, it's just that the inputs and outputs are limited to tabular format. Some problems are tricky and require programmer skill to solve.

    What about assember. It has to be more performant

    Yep, using SSE and MMX inline instrinsics embedded in my C++ code I can get a speed up of up to 16x. C++/CLR's support for mixed assemblies (.NET + native) rules! an interface for my C# GUI code with assembly level code at its core. One of the main reasons I like .NET.

  • Netbook recommendations
    J John Stewien

    I can't do without my netbook but there are 2 Really important things: - Get one with more than 1024x600 screen resolution as that really sucks. Ideally 1366x768 or more. - Get one with at least 2GB RAM, 1GB really doesn't cut it. I can recommend getting an Acer as I've been torturing one for over 2 years and its still going strong. The 1830T is good.

  • .NET or Java?
    J John Stewien

    The answer depends on the sort of person you are. Do you like your frameworks to be solid and slow to change (Java), or do you like to live on the edge a bit (.NET)? I love .NET because of the flexibility it gives me. Most of the time I'm a C#, C++/CLI, C++, ASM programmer. With .NET I can do all the GUI, Web and Database interfaces in C#, do bridging to legacy libraries in C++/CLI, and use C++ intrinsics in code blocks marked #unmanaged where I can do high performance assembly code for where I can leverage SSE and MMX. I do all this in one integrated IDE, one solution, and with one Mixed Mode debugger that allows me to step through the whole lot, all the code lines and calls, from top to bottom. Fantastic! I can choose which GUI framework I want depending on if I want a really quick and dirty Winforms app, or a pretty WPF app with databinding. For canvas type rendering I can use Winforms with an OnPaint handler, WPF visual tree, DirectX, or OpenGL through C++/CLI. It's all just so flexible. Custom devices with odd device drivers, not a problem. Legacy protocols and libraries, not a problem. Big flashy cutting edge GUI with a performance critical backend, not a problem. .NET is the glue that holds my life together. I also do Java when I have to, and Java has the advantage that it has some really good, mature frameworks. There's no denying that Java is solid, and makes a great backend platform. .NET seems to be in constant flux, and that means that often you are taking a gamble on what direction Microsoft decides to take in the future, this does spark some emotional unrest as you can see in the Silverlight/WPF/HTML5 debates going on around the net at the moment.
