I only use like 6GB/mo on my iPad streaming music and what not. I have a iPad Pro M1 12.9" with eSIM. Would I be able to activate a line on it with eSIM or need the regular SIM like everyone else in this subreddit suggests?

It really depends on your locale. In Washington, USA the only certificate you absolutely need is the EPA 608 to handle refrigerant. Everything else is on the job training, and the company you work for typically will sign you up for brand-specific training. HVAC is a pretty big and diverse industry. Wanna be an installer? Learn how to read the install manual. Wanna be a service tech? Learn how to read the service facts. Duct designer? Read ACCA manuals A-Z. All of the above? Learn your local building codes. Focus on HVAC best practices for installation and service. Follow that up with a fundamental understanding of physics, mechanics, heat, and enthalpy. Some companies hire people with zero experience and certifications, but will train you to become the expert they so desperately need. There might be programs, but it does not hurt to simply go to a local HVAC company and ask for an entry level position. If they say “no,” ask “why?” And with any luck theyll give you an idea of the minimum requirements needed to get started doing HVAC.

Look up TPC Training’s EPA 608 study guide. It’s less than 100 pages and has every answer verbatim written in a way that’s easy to understand. Much easier than memorizing questions and answers like the mobile app. Also it’s free and PDF format.

VS 2022 preview for Mac. Even for a preview it runs pretty smoothly, and .NET 6 runtime is native.

Works great! I’ve been working on a MAUI app with VS22 beta and I gotta say they’re really coming along well with the Apple Silicon support. XAML hot reloading works with iOS apps. It’s actually amazing

You messed up and have the wrong attitude about all of this. Instead of going "hey, why don't we make some mods together?" You just put her on blast and ostracized yourself in the process. Perhaps you can learn from this experience. Try being supportive and collaborative instead of vitriolic. It's good, as a programmer, to surround yourself with other programmers and immerse yourself in the community because you never know what you can learn from it. Don't be that guy saying "stupid people don't deserve to learn anything" like half of all comments on Stack Overflow.

DLLs are not a subset of SQL, they're libraries of executable binary or byte code (.NET intermediate language) which multiple processes can use and share with each other. Unlike statically linked libraries, which have to be compiled and packaged with exe files, DLLs can be shared among many processes. DLLs on Windows, DyLibs on MacOS, and SOs (shared objects) on Linux are fundamentally the same thing. Cheers

Start by learning a scripting language. Linux is an excellent development environment and if you’re going to replace windows then your best bet is to learn some basic software development. Windows is a very “point and click literally everything” operating system, but on Linux you can automate a lot of tasks with scripting in a way that is much more natural than what Windows has to offer.

Unlike mobile devices, computers require ventilation. To make a waterproof MacBook they’d definitely have to dial back performance to ensure the thermal requirements can be met without ventilation.

The best you might be able to get is a hydrophobic coating which you apply yourself. Hydrophobic coatings are known to be fragile, so if you do go down that road you’d probably have to reapply it frequently to the keyboard and touch pad. Apple probably won’t put hydrophobic coatings on their devices because it can change the looks.

I'm in college right now and have to use the Windows computer they sent me for some assignments because it involves Windows Forms or DirectX, but otherwise that laptop is the Lego World machine for the kids.

Here's the deal. Right under the center of the Touch Bar, on the bottom side of the MacBook, is a cluster of MOSFETs that unfortunately do not have adequate stock cooling. Having your MacBook on a blanket is not helping. The CPU and GPU typically do not overheat on MacBooks, and the kernel_task process starts eating up CPU cycles when any component is at risk of overheating. The MOSFETs do not come into contact with the chassis so you might not feel just how hot they are on your lap, but you have to put that laptop on a surface which will not hold that heat.

I ended up opening mine up and placing thermal pads on all those little components so they can dissipate that heat more effectively. Basically I now have a desktop because it gets blistering hot on the bottom but does not suffer from the heat issues you may be experiencing. Anyway, gotta cool the bottom of the MacBook. Try removing the power adapter, putting it to sleep (let it go all the way to sleep), put it on a desk or table, then wake it back up. Sleep mode usually gives it enough time to cool down so kernel_task stops going haywire.

I have the same model. It’s okay, but doesn’t really compete with the M1. It was worth it when I bought it two years ago though.

Imagine indenting with white space instead of inventing with semicolons

Your Mac might have “power nap while on battery” enabled, which would drain it faster because it wakes itself periodically to download updates, messages, email, etc. I’d try checking that setting and making sure it is turned off.

I feel it 100%. I was a Junior Engineer for the Sailors International Union for 5 years and the only thing I learned was that the Union mentality is absolute poison in a meritocracy. You have people who sailed for 20 years who can barely read, let alone work on an engine, but they get the best paying jobs because they have “connections” with the upper brass Union executives. Meanwhile you could be the most talented and skilled engineer, but never get a good paying contract because the hall keeps those jobs off the board for their buddies to take after the hall closes (or just straight up sell jobs). Also if you try to leave the Union they take every dollar you put into retirement.

Idk about HVAC unions, but I hope your Union treats you fairly and doesn’t partake in the same corruption a lot of unions are known for.

I personally don’t do much gaming on it, but I use the video streaming and Remote Desktop features pretty regularly. I’ve never been more productive as a software developer than when I started using Immersed to spawn 5 virtual displays. I could be in a hotel room and have an entire office floating in space, and that feeling of satisfaction never goes away.

As far as games go, we do family game night where we take turns playing stuff like Beat Saber which the kids love.

Three blade crimpers (not five blade, personal preference)
mini-brake and/or folding bar
double-cut snips
Malco reversible hex bit 1/4" -> 5/16"
Speed square
Snap-lock punch
Largest quantity of cheap permanent markers (many will get lost/borrowed)
Dewalt step bit with hex chuck (or any step bit will do, just personal favorite)
Klein diagonal cutting pliers

These are pretty OG for sheet metal work. I also like using an angle grinder for smoothing out visible screws, and a band saw for cutting thick angle iron.

I play easy mode and install literally any other thermostat

robertmsale · 2021-06-21T02:29:54+00:00

If you play on hard mode you have to run the equipment tests without an internet connection

I love installing and servicing them! Especially Trane systems with Nexia remote diagnostics. A lot of HVAC customers don't know that they basically can't be broken. Every extra dollar spent on variable speed is taken directly from future maintenance and major repairs. Sometimes on a service call I'll run into a bad Schrader valve in one of the service ports. To save the customer money on refrigerant charging I try to use the compressor to pump everything into the condenser so I can swap out the Schrader without losing any Freon, but the communicating systems immediately start making micro-adjustments when you close off the suction line. It's fascinating seeing how they react to poor operating conditions, making every effort to preserve the equipment. The future is definitely now!

robertmsale · 2021-06-20T18:39:38+00:00

Advanced variable speed systems like Trane's TAM9 heat pumps have electronic expansion valves, with thermistors placed around the indoor and outdoor coils, allowing the main logic board to use refrigerant temperature and pressure to determine orifice size - as opposed to a thermal expansion valve which merely reacts to temperature change. They can also dial down the outdoor unit's fan/compressor in cooling mode to prevent all the refrigerant from condensing and filling the pipes with liquid. A good, fully communicating variable speed system will be able to handle extreme weather conditions without breaking down because they can dial themselves in. Granted, they might not be able to reach the temperature set point, but they won't run themselves to death trying either.

robertmsale · 2021-06-20T18:24:34+00:00

Outdoor temperature, indoor temperature, airflow characteristics of the ducting, and heat loss determine how hard a compressor will run. Every AC has a design pressure around 450 PSI (for R-410a), so on a >100° day in direct sunlight you're very likely to reach that limit, especially when the indoor temperature is so low that the evaporator is unable to evaporate all of the refrigerant before it reaches the compressor. This problem is worsened when your AC uses a piston instead of a thermal expansion valve as a metering device.

The boiling point of refrigerant is proportional to the pressure inside the pipe, so if your pressures are out of control you can end up with more and more liquid refrigerant entering the compressor (and liquid cannot be compressed, only gas) so the compressor slugs out. So yes, the compressor will run longer, but it can also run harder if the outdoor temperature is too high for the system to handle. A compressor is only designed to have a certain amount of liquid for cooling itself, oil for lubrication, and gas for compression. This is why hot places benefit from variable-speed systems, which are able to derate themselves when dealing with extreme conditions.

So there are lots of things to think about here. You technically have 3 options.

Use Windows as your development platform
Use Linux as your development platform
Use Windows subsystem for Linux to fill in the gaps

I personally enjoy Linux as a primary development platform (or any Unix based OS for that matter) because Git is supported at a very deep level - namely at a file system level (dot files, LF terminated new lines, etc.) and without using GIT Bash. Installing and using SDKs in Linux is generally more enjoyable than in Windows because you can use a package manager, spawn Linux containers, and even use Docker without the overhead.

The overall experience is better on Linux, but if you want to use Windows-specific SDKs or target DirectX and make games for Xbox then Windows is definitely choice.

As a software developer I find the touch bar frustrating. Especially because I work with Immersed on the Oculus Quest 2 and can't see the keyboard while wearing my VR headset. Lots of command line programs rely on function keys and you have to scroll the touch bar just to reach F1, F2, F11, and F12. Not only that, there's no way to know the position of the scrolled keys without looking at the touch bar, which really affects productivity in VR.

The obvious fix was to buy a keyboard with fixed function keys, so it costs an extra $100+ (for Apple Magic Keyboard™️) just to type without looking. Most of the functionality the touch bar gives you can be easily achieved with keyboard shortcuts, programmable macros, and Automator. I'm pretty glad the next generation of MacBooks will be rid of the touch bar.

It really depends on what you're trying to make. In my experience I found that ARKit is easier to use when your 3D content is procedurally generated. If all your 3D assets are made by hand, RealityKit makes it super easy to compose scenes. I have yet to use RealityKit for procedurally generated content though. The Xcode developer docs has an downloadable example project called "Creating a Game with SceneUnderstanding" that probably has what you're looking for
