No. If you run low voltage DC that matches what devices need (5V or 12V, typically), your wiring is staggeringly huge. Not only do you need the fat wire to carry the current safely, you don't have much room for voltage drop. Dropping 5V on 120V under load isn't a big deal, dropping 5V on 12V under load is literally unusable for most devices (12V stuff won't run on 7V).

If you run something sane, like 48V or so, then you still need conversion electronics at each point of use, and you don't gain much over just running 120/240VAC, except that now your converters are really expensive because they're less common and "weird." 120VAC to 5V is super common, 48VDC to 5VDC is less so. Some switch mode power supplies will work on DC, some won't, and it's harder on the bridge rectifier diodes, so they don't tend to last very long in that sort of use.

It's the sort of thing that sound good in isolation, but in practice leads to spending a lot of money to gain little or nothing in terms of efficiency.

The exception is for a small system where you can run 12VDC to LEDs and stuff (think a camper), and avoid bringing the inverter online at all. Inverters have a significant idle draw more or less proportional to peak power delivered (my 2kVA inverter idles at 30W DC, a 6kVA one that can hold 18kVA for 20 seconds idles at 100W DC).

I'm fully vax'd and boosted. I'll probably continue to get boosted in the future. All that said? I feel like the government did a really bad job communicating who needs the booster and when.

First, they gave vague recommendations to immunocompromised folks. They said everyone else probably didn't need it. Then they said well, ok for older folks. Then this new omni variant comes out and they're badgering everyone to get boosted NOW or your no longer considered fully vaccinated.

There would have been so much less confusion if they were consistent with their communication from the start, and did a phased rollout of the booster just like they did with the original vaccine.

Edit: My point is that they knew there was reduced efficacy of the vaccine back in September. They knew the general public would eventually need a vaccine. They should have had a plan to gradually get the population boosted. If they had, most who wanted a booster would have had one before omni existed.
Apparently if you go on maternity leave or extended sick/disability leave the relationship can also go bad. I think there are a significant number of cases where the relationship goes bad because of reasons other than just straight poor performance. But certainly, sure, straight poor performance is a frequent reason.

I don't think that unions like AWU are particularly concerned with the general performance review process.

I took a similar route, albeit much less intentionally and spanning almost a decade. Software QA -> Business Intelligence Analyst -> Data Scientist -> Data Engineer.

Here what I'd recommend today:

1. get very comfortable with Python. Scripting isn't enough, you'll need good OO principles, understand how to manage projects/libraries/dependencies, etc. This will take the longest, so start it first.

2. Read and re-read Designing Data-Intensive Applications by Kleppmann. This is the bible of data engineering and far outclasses anything else currently available.

3. Get your hands dirty with modern tools and the whole data lifecycle. DBT, Airflow, Snowflake, Postgres should be obvious (feel free to substitute prefect, clickhouse, etc. if desired). You'll also want familiarity with a cloud stack and how to manage it (terraform, pulumi, or CDK). A public portfolio project would be great, but being able to talk confidently about the how and why of these things is probably enough.

The hard part is getting that next job. Look for junior roles at big companies, and mid-level roles at startups who don't understand the data ecosystem yet (almost any startup whose product is not ML or ELT). The former will give more mentorship, the latter will be easier to get if you can talk the talk in an interview.

I do the same, but wait until the headache starts, rather than anticipating it, to drink something caffeinated. I've found this helps me quit faster, and a 10-minute headache isn't insufferable (a single caffeinated beverage usually ends the headache quickly for me). I've never needed more than 2-3 days to get passed that part.

But, like you, I've never tried to totally quit. I "test" myself by usually abstaining from caffeine on the weekends. If I get even a slight headache, then it's time to cut back.
But those machines are sooooo coool. Also, they give you ketamine to intubate, so more fun!
I'll be the contrarian. I was a pot per day drinker and quit for three months and felt no different, just missed the coffee. I quit the quit and I'm back to a pot per day, feeling much better.
Even if most communication is async there is a part of "somewhat async" and a part of "mostly sync" communication. And then there is the social aspect of not being alone, but "seeing" that others are working as well.

On the semi-async stuff: If I am stuck with a task I probably can grab a coffee and eat a snack or check mails, but I would like to get some feedback soon, while I'm in the state of mind of that task. Else I switch completely to a different task, which has effort to come back on speed on the initial task on e the feedback is there. And if there is some clarification needed, it is good if all parties focus on that topic for a while, till key questions are cleared and everybody is unblocked.

Of course it is a balance.
I think 10 million documents is a large corpus. A retriever like Sklearn TfIdf will have a hard time handling it in a reasonable time. The main goal of Cherche is to prototype a neural search engine quickly and with a large choice of retrievers and rankers for corpus sizes < 1 million documents which is a common use case in the industry.

Search implements a wrapper of the Python ElasticSearch client that is scalable and dedicated to corpora composed of tens of millions of documents.

that chip can suck down 150W of cooling (which is likely the cooling setup that benchmarks will be running with).

Not going to argue semantics here, but the grandparents point was that cooling the intel chips tends to be where it falls down (thus, the real world may differ significantly), even if there are paper gains in game benchmarks.

Offering a chip which takes double the cooling is just leaning into their point.

Rails is shockingly easy, especially Rails 7.

Strait up, use Rails with all the defaults (ImportMap, Hotwire) but use Postgres and maybe Tailwind (`rails new myapp --database=postgresql --css=tailwind`). No extra gems are needed really (if anything, they add more complexity as not all are updated to be compatible with Rails 7).

Re: "not plain English" - YC is BY FAR the most transparent and founder-friendly VC seed investor and goes to great lengths to educate founders.

This is as clear language as financings get in startup land.

If you're unwilling to learn basic terms and concepts of equity financings, than building a company using VC is probably not for you (which you seem to already know, given your "I'm interested in running a profitable business... and not owing anyone anything").

If, however, you have an idea that you think could be massive, and are therefore considering raising money from VC to get there faster, then you could start in no better place than YC.

Convert simple text to database script-(text2db.com)
Hi, I'm the creator of https://text2db.com/ , I have build this tiny tool to quickly create database script without any extra knowledge of script format.

This is my first project to help new learners/developers to quickly create database script using predefined symbols, Once in my company I had to design database, containing more than 10 tables
with foriegn key relationships, I had used this tool to create database in minutes (instead of using interface to create database).

I want other people to save time creating databases.

This website is still in progress, for now only MYSQL,PostgresSQL and MSSQL are supported.

Not really, I've done a lot of hard drugs, except heroin/opioids/benzos, and I'd say caffeine is the hardest to quit. Literally been on a 3 day binger awake and couldn't figure out why my head hurt, thought it was food, water, oh
no whoops it was a caffeine withdrawal.

Everything else I can do on and off, some things it's been years, caffeine I've only quit once. Lapsed and haven't been able to again.

Many (most? I always take employer-sponsored, not an expert on all plans) health insurance plans in the US have a concept of out-of-pocket max. This is a yearly amount that is essentially your maximum yearly liability. That amount can vary from plan to plan and year to year. Usually a lower out of pocket max means higher premiums, similar to the idea of having a lower car insurance deductible usually means higher premiums.

It looks like all plans sold through the healthcare.gov marketplace is required to have out of pocket maximums.

Ok. Can you agree that it should at least be an improvement in carbon emissions?

Grid tied solar often manages this, though exceedingly poor panel utilization as in the article typically won't. By the time you start adding batteries, you're unlikely to be net carbon negative during the system life. It's hard to get solid numbers for modern battery construction, though. They tend to be trade secret sort of values.
Solar generally pays off if your state/municipality offers SRECs and you get the Federal tax credit. In some places, like Washington DC, it goes as far being lucrative fast. My entire system will be paid off in under 5 years. After that, no electricity bills plus SREC income for another 10+ years.
The idea is to use the reflectors during winter or on cloudy days, etc. Too much labor for me, but still interesting.

But under what required re-payment terms? My understanding is that SAFEs are not really meant to be debt instruments, and that they are highly unsecured / non-collateralized forms of debt.

I was recently screwed over as an angel investor in a SAFE deal where the startup got acquired before their Series A, and I was just completely out of luck. "Thanks for the money, sucka" said the startup. Not verbatim, but that was the idea. Startup got the seed money, founders got the acqui-cash, angel investor chumps got nada.

As to debt, you might want to read this: https://www.upcounsel.com/safe-notes

Yes, SHA-512/256 is often a good option, despite its tragically confusing name. But (maybe going off on my own tangent here) it's got a few important shortcomings:

1. It's less widely supported than SHA-256 or SHA-512. For example, it's present in OpenSSL but not in Python's hashlib. A reasonable workaround here is to just truncate SHA-512 yourself, which gives you a functionally similar but not-output-compatible hash. But no one loves monkeying around with standards like this.

2. SHA-512 doesn't have any hardware support that I'm aware of. SHA-256 has dedicated hardware acceleration on lots of ARM chips and recent x86 chips, which is very nice. But SHA-256 doesn't have enough margin in the digest size to truncate it. (SHA-224 is a thing, but it dumps more collision resistance than we're really comfortable with, in exchange for being only slightly resistant to length extensions.)

3. If your goal is to construct an XOF, SHA-512/256 is kind of perversely inefficient. You end up throwing away half your output bytes to prevent length extensions, but then running the hash (or at least the compression function) again to get more output bytes. On the output performance side, this is leaving a free factor of two on the table.

Well there is L-theanine[0] which I always found was the opposite of caffeine, and when you combine it with caffeine (500mg theanine & 200mg caffeine), you get a sort of flow state without the jitters of caffeine.

L-theanine takes the edge off caffeine. You could also just try L-theanine on its own.

This person needs to experiment with other nootropics besides caffeine. I've tried various stacks over the years like Alpha Brain, Mindlab Pro and a few others. They've been instrumental in getting shit done on a tight schedule, and I don't get that jittery 'wired' feeling you get taking plain caffeine supps on their own, just a mild flowy state (thanks to the L-theanine).

> there should be exact calculated amount of fuel left

Nothing is exact :) Ariane upper stage boosts JWST on a certain trajectory +/- some error in all directions, and then detaches. Along the way, they figure out the error and JWST corrects it with trajectory correction burns. This is somewhat independent of any fuel left for the "underboosting" you're talking about.

A mission designer looks at the performance specs/error distribution for Ariane and tries to include enough fuel so that, 99.X% of the time there will be enough for trajectory correction maneuvers AND a 10-year lifetime. When the (Ariane) burn is precise, errors are small, and less fuel is wasted on TCM, leaving more for the mission itself.

What this (10->20 year lifetime adjustment) really means is that NASA's left quite a lot of margin for TCM here... Which, for something this expensive, was a good thing :)
Sprint goals are based on capacity, which is loosely defined by how much your team works. Defining how much you need to work by basing it on how much you should achieve, which is based on a number defined by how much you (and your team) work, is circular reasoning.
You can get bean-to-cup machine and mix 50/50 or even 70/30 decaf and normal beans - it works very well (look at quality of decaf, make sure it's water or co2-decafinated not chemically-decafinated). Also as I said above L-Theanin works very, very well with coffee to relieve unwanted symptoms.
Sure, 1% of conspiracy theories turn out to have some truth to them — but on the whole, if there’s no way of knowing in-advance which ones those are, I don’t know if “engage with all the conspiracy theories, spend time and energy attacking fictional problems and innocent people” is a better response than “reject all the conspiracy theories, spend time and energy on definitely-real problems, allow some dodgy organisations to get away with stuff”...

> I have to spend extra time and energy planning for the case where they don’t follow through

This is why establishing trust is critical to any high performance org. It’s the basis of much of Military Spec Ops training. What makes SEALs, SF, Rangers and other SOCOM units so effective is how well they screen members for trust. They would rather have a mid-level performer with high trust than a high level performer with low trust. No one has the time/energy to be checking up on what is assigned or what you say will be done. You have to trust it explicitly. This is what makes these organizations hyper-effective. When trust is low procedures, process, and bureaucracy take over - all of which leads to incredible inefficiencies. I like to say Trust is currency.
I think a lot of this depends on the typical severity of Omicron (and future variants).

I'm vaccinated and boosted. I wear a mask in public. I don't go out much. I do travel fairly regularly (fly maybe 1-2x per month). I finally got Covid last week, likely on a flight. I had ~3 days of mild cold-like symptoms (sore throat, runny nose, congestion, very low grade fever that approached 101F). It was far less severe than any flu I've ever had. I extended my trip by a week to meet how I read the CDC guidelines (which are clear as mud for mildy symptomatic cases).

If the severity for everyone was that mild, then I'd say we're done. However, I worry about the unvaccinated and the unboosted. I wish there was better data on the severity of Omicron for different categories of people.
Sudden braking from a fast speed might be more likely to cause a skid (same as a car but scaled down), but if you're popping down to the shops or commuting to work, you likely will be cycling in a more relaxed style anyway. If you're uncomfertable with braking in the rain, I recommend finding a quiet strip on a rainy day and seeing what it's like. Actively try to skid so that you know what your bike's limits are - from decade of experience cycle commuting in a famously rainy city with some highly aggressive drivers, I've never found the rain to cause additional issues beyond getting wet if I'm unprepared.
The only time I have ever come off my bike by my own fault was skidding over a patch of ice about 9 years ago, so I would recommend higher levels of caution in the snow.
