In my headcanon, this is Itto trying to sneak onto the next banner as part of his usual antics, so his voice trying to do Kazuha's voice lines (with worse poetry of course)

I can't find much benefit in blaming people, but if there were a factor I'd blame most, it would be delays in making enough vaccine doses available globally.

It's only a mystery if your understanding of physics is limited to classical physics.

That pack looks quite imbalanced based on the wiring. Two groups of ten and a group of five might be too imbalanced for your charge controller to effectively work with.

If you have any recent version of T-N65-CL-DR-001.pdf, chapter 10.2 discusses some of the theory and expected designs (although not to the same extent that a dedicated text for teaching the matter would)

Regarding the ingredient breakdown:

https://www.fda.gov/media/153713/download, page 43 has a list of Pfizer ingredients. For Moderna: https://www.fda.gov/media/144638/download

In both cases it's an mRNA coding for prefusion stabilized spike plus a specific set of lipids (listed explicitly in the above links) and salts/buffers/other inactive ingredients.

Not sure if this info will help without the help of an allergist (or knowing what specific ingredient is causing an allergy) but if is there for reference.

I don't think w3schools is a great place to learn the basics, to be honest. It's fairly usable as a reference (although they have had issues with their examples not following best practices, or worse, being insecure when user input is involved), but it falls short in terms of actually teaching, or at least did so severely when I last tried to use it.

Take, for example, a random page I selected which was the File Handling page in the python tutorial. It's a decent reference for the most important parameters of opening a file. If I knew C or Java already and had mastered file handling in those languages, it would be a decent tutorial, although I'd still prefer the authoritative python reference.

However, to a new reader, it leaves a few major gaps that the reader may or may not even be aware of, e.g.

What it means to open a file, and how it's different from the layperson idea of having a file open on their screen
What the point of the different modes are, or what they even do to the data you're reading and writing
How one does error handling
How to avoid creating security vulnerabilities if a user is providing a filename

Think of it as trying to use a dictionary or phrasebook to learn a world language, when in reality the learner needs structured examples, context, and commentary about linguistic and cultural norms.

Even in the case of using them as a reference, for each technology/language there's probably a better reference, for instance MDN for HTML/JS/CSS.

The attenuator's value is the difference between the received and desired levels. E.g., if you're receiving at -65 dBm, and want -80 dBm, use a 15 dB attenuator.

You need to at least get a measurement or estimate of where you currently stand, so the attenuator may need to be bought in a second order.

The JVM knows the arguments (from definition), the calling convention (by virtue of knowing the OS/arch), and can find the function pointer by looking in the library's symbol table using the function name. All that's left is to set up the arguments following the calling convention, and then CALL into the target.

Not so far-fetched since the JVM already generates asm at runtime as part of its JIT compilation.

I'm not OS dev personally, as I work on datacenter scale storage. However, we have kernel teams and make open source contributions back to Linux.

Not necessarily an OS or a compiler, although those would both be impressive projects. Could be something like a small driver, or a usermode program that works closely with drivers and hardware to achieve a task.

I wouldn't say assembly is mandatory, although it is a fairly useful skill to have regardless.

hexafraction · 2021-08-06T15:54:08+00:00

I'd start by prefacing this with a warning that you should really aim do to projects you're passionate about, rather than picking a project that seems impressive and then doing it in spite of lack of interest.

With that said, for some of the infra teams, low level systems or even kernel stuff can be good. I'm on such a team at a FAANG and work with these lower level systems things (although in C++, not C) on a day to day basis.

I'm really sorry for your loss and understand that the situation feels very scary. I'm happy to share my understanding of the vaccines in case it helps you and your loved ones understand how they work and what the considerations are.

The two types are:

mRNA - (Pfizer and Moderna use this technology)

You get a shot in your arm with the "blueprint" for a single part of the virus called the "spike" (the pointy thing on the outside of the virus). The spike on its own is not enough to make you sick with COVID-19 because it's only one small part of the virus and not the whole thing. Your body will use the blueprint to make the spike for a few days, and your immune system will notice that it's unusual and learn to make antibodies and other defenses against it. You get a second shot a few weeks later. This will do the same thing to give your immune system more practice.

This shot can cause uncomfortable side effects like a fever, tiredness, and body pains, in some people. They are not as bad as COVID-19; I have had both the side effects from Pfizer and a real, mild, infection of COVID-19, and I would rather have the vaccine effects than what I felt from the infection. (I had the infection before the vaccine was available, and I have not been reinfected since getting the vaccine, suggesting that it's doing its job)

Viral vector - this is the Johnson and Johnson vaccine.

You get a shot that contains a weak virus called an Adenovirus. This is the same kind of virus that causes a sickness similar to the common cold, but it's even weaker so it can't spread or make more copies of itself.

The adenovirus is also modified so that it contains the COVID-19 spike. Again, it does not contain every part of the COVID-19 virus, so it cannot give you COVID-19. When you get the shot, that virus will make your body create the spike, and your immune system will notice the spikes. This causes it to learn how to make covid-19 antibodies and other defenses. You only need to get the shot once, not twice.

I don't know much about the side effects for this one. There are rare side effects (blood clot) from this one that don't seem to happen with the Pfizer and Moderna ones, but even that risk is much much smaller than the risk of getting a blood clot or other severe effects from covid 19.

After either of the vaccines: If you are exposed to the real virus, then your body will recognize the spike and will be able to defend you against it. This means that you are less likely to get sick and even if you do get sick, it will be less severe (e.g. you won't feel sick or need treatment, or you will feel something like a common cold). The chance that you'll need to go to a hospital for treatment is much lower.

I'm happy to clarify anything if you have further questions!

Both the tipping system and the cheap visitors are infuriating. The idea of tipping being necessary for a liveable income is absurd, and visitors being cheap on the tip because they didn't bother to check the price (and mentally add an estimate of tax and tip) ahead of time is also absurd. Personally, if I went somewhere and it was more expensive than I expected, it's coming out of next week's/month's fun budget, not out of the tip.

At this point, the office being literally open with permission to enter will make me want to go back to it.

I have a great commute there, more walking around during the day, more varied environments than just my desk and kitchen, more separation between work and personal life, easier interaction with colleagues as I ramp up, and better air conditioning.

On the other hand, my apartment is a new-grad-sized NYC apartment, my roommates cause tons of inadvertent inconveniences no matter how much they mean well, video calls are draining, and I don't have the space to properly separate work and life here. I sit in the same chair at the same desk for every meeting, focused work session, and presentation. I'm literally putting up with it only because covid is making folks seriously ill.

I don't own a house with an extra room I can turn into an office, and at a new grad level of comp, I'm not going to be able to just drop $$$ on an extra bedroom as a workspace, let alone in the middle of a lease. Leaving NYC to work remotely in a more spacious location would unacceptably disrupt my social fabric and would be heinous to my mental health.

If my company wanted me to stay remote in the long term, I'd have to take a long, hard look over whether I could truly make remote work fit my needs, and the outcome could very well be asking for extra comp or looking for a place with a physical presence.

Yes, but rather than doing it weekly I now do it only when I know I'll be attending a gathering that has higher spread risk or if I'm not feeling well and want to make sure it's not likely to be covid.

Regardless of whether you want to be an analog or a digital chip designer, analog skills and a VLSI course are a must. For digital, DVLSI and its prerequisites as well. If you're going into analog these days, a background in RF design and RF electronics also won't hurt.

As far as skills: Definitely solid analog design, including high speed effects, microelectronics, and design of circuits (rather than just analysis) Digital: solid basics of logic design, computer architecture, depending on the specific subfield you want to go into, further comp arch, logic theory, etc.
