To compute walkability we followed the PCA approach outlined in the link below:
https://www.semanticscholar.org/paper/A-Data-Driven-Framewor...

This means that the score is considered relative to other areas in the US. A lack of sidewalks will negatively impact the score, for sure. Can I ask, how safe is it when there is traffic?

All of the above being said, if the score feels very wrong to you, it probably is! This will be a reflection of the fact that this is still at MVP stage
Novamin is very different from other toothpastes. I can feel it with my tongue - my teeth become glassy/hard in like 10 min, and the effect persists to the next day. I can’t speak to anyone else’s experience, but I can detect a scam toothpaste pretty quickly & send it back.
I had been looking to do this exact thing for so long. It didn't occur to me that it was possible to unlock the AT commands for the pinephone. I just wanted to turn it into a modem. It's a pretty solid price for that piece of tech alone, since dev kit LTE modem boards are >$100 in all the places I could find.

Thank you, sincerely!

Very cool. Genuine question: is using the URL as the encryption key considered secured enough for most usecases?
I imagine most people share these links via email, and if you or your recipient use a non-secure email provider, we should expect it to be parsed.

There was an article in the WSJ today about Facebook running Chinese propaganda ads that try to dispell the Uyghur genocide.

Last year the pandemic wiped out a bunch of the travel sector. Lots of travel companies went under or were acquired. Lola moved fast and expanded into the FinTech sector. We launched an MVP of our new Spend Management platform in three months, and six months after launch we're up 150% MoM in customer spend.

Our early customers rave about what we've built, and we're really excited for whats up next. We're entering a crowded space with some competitors that have valuations over $1B -- but we're winning deals against them when we go head to head. Our approach to the customer problem is unique, and CFOs of SMBs get excited when they realize what we're building. It's a fun place to work -- we don't do death marches, and the engineering team has a strong voice in how we build product.

We've got a strong leadership team in place. Our CTO is Paul English, the former co-founder of Kayak, and Mike Volpe, the CMO of Hubspot, CyberReason and a few others. They've helped other startups get big, and we're all really confident in what the rest of the year is going to bring.

I think the best solution is to not take anothers word for for its worth. Have a look at the system itself and tackle the issue of whether it benefits society/yourself/Group You Like, or not.

I also mine Gridcoin. I don't know how much I have ATM, but I like that even when I'm away living my life, in some small part I'm helping a scientist find something new. The reward is just there to help with on boarding in my mind.

If the coin ever jumped in price and a few miners see it as an investment, well hey its better than mining bitcoin and producing less useful data.

Gemini has decided to invest in a "technical solution to a social problem". Usually a terrible idea, but having spent some time in Gemini they seem to be succeeding. There's more concentrated random, weird, interesting stuff there than you can find on the web.

Notice that there's more of that stuff on the web, but you can't find it because search engines don't lead you there, and link connectivity between the interesting parts of the web is low.

It can actually represent all integers just fine. It works like any other base, except whereas for example in base 10, positions are multiplied by 10^0 = 1, 10^1 = 10, 10^2 = 100 and so on, in base 1 they are multiplied by 1^0 = 1, 1^1 = 1, 1^2 = 1, and so on. The result is that each digit adds 1 to the number, like tally marks. So we have, for example

111 = 3

11 = 2

1 = 1

= 0

-1 = -1

-11 = -2

-111 = -3
The problem with doing that is that it raises staffing costs, which is one of the things (the major thing, afaik) you're trying to optimize away by going to the cloud. You have to be cloud agnostic, which means not using value add services. No more SQS or the GCP/Azure equivalents, you have to run your own Kafka in case one of them goes evil.

If all you're using is VM's and their infinitely scaling ability, it can pretty easily become cheaper to just run your own hosts and manage a pool of not-yet-in-use hardware. Or to do something like setup greenfield stuff in AWS, then at the start of the next quarter, buy hardware for the stuff in AWS, migrate it to in-house, and start over again.

I don't find cloud-agnostic to be that compelling of a solution, generally. It really only makes sense to me at small footprints. Even then, I'd probably only suggest it if you needed a really small footprint (like 1-3 servers) across a large number of geographic sites, and for some reason you can't just use a CDN.
Another problem is whether you believe you own anything that exists, or whether you just participate in some shared belief in its existence.
110%. I've never had any desire to work outside of my home whatsoever, and there wasn't a single day of office work in the past that I wouldn't rather have spent at home. I wish I could stress enough how much I hate commuting to an office, being around and hearing people, and being obligated to leave my home just to sit and type on a laptop like I could do at home.

I enjoy working on many types of problems and look forward to hearing from you!
The biggest issue I see is that LEEDs allow for a building that looks like a big heat exchanger, and has zero heat insulation to certify for high power efficiency in a cold climate.

Canada, and Toronto area had tons of LEEDs certed luxury condos being heated like no tomorrow in Winter.

Things are even worse in Vancouver, but that's offset by milder weather.

The opposite picture is there in hot climates.

Building with exposed balcony slabs, and curtainwalls in +40C° climates, guzzling electricity for aircons.

I think the West needs to look up more for economical building designs from nations living in extremes.

Gulf countries learned how to build economically in +50C°

Nordic ones for -30C° in Winter

None of them spend as much as US, and Western Europe on heating, or cooling despite way more severe climates.

Building operation is 40% of US total energy bill if we believe CTBUH https://www.researchgate.net/figure/US-Energy-Consumption-by... . And 40% of building energy bill in US is space heating https://www.epa.gov/rhc/rhc-multi-unit-housing

All those vanities like PV panels, solar water heaters, rainwater collection, turbines, etc — all totally pale in comparison to just proper thermal design of a building, and slashing its heating bill.
I have always found that people that enjoy science are comfortable with uncertainty. I worked at Bell Labs for 16 years from the mid 1980s through 2000, and I found a lot of people still looking at things that "we all understand" and still wondering about how it really worked.

Science is never 'settled'. There is the current understanding of the art, but that current understanding is not always fulfilling. There are edges and holes in most domains in science where people are poking around wondering how it really works.

A lot of the things I implemented as an engineer (I am not a scientist, but I worked with scientists) were attempts to answer questions. Many of them having to do with "how do we measure this thing, without touching it?" Modeling information and making decisions based on observations against what you were expecting to observe.
In this case the problem is that the sovereignity of the nation has been undermined by a military coup. Which is to say: Unless you believe in the rightfullness of the right of the stronger which in political terms would amount to believe into some elan vitale, a will of the biological organism of the people, some superstition of thinking blood and soil (which is to say a mob of antisocial males) to be the (metaphysical) being of what is considered the nationstate. (Some might also argue that the nationstate has had terrible consequences for the average worker in the dawn of modernity (that bit of history is probably specific to western history))

adding on this: I'd agree with the notion that it is weird that people fetishize the internet as some anarchic free entity when on a material level it is owned in big parts by private interest.
Probably it isn't because there's PTC Creo, CREO Solutions, Creo Technologies, and Creo (from Creolabs), an app development platform.

Honestly you are talking rubbish. Bitcoin is currently just below it's ATH, so if anyone lost money it is because of stupid trades and not because the value of what they bought diminished severely.

So according to your research 99% of people who have bought it have lost money. That's complete bullshit, I personally don't know anyone who has lost money, they have all made significant returns, so unless they represent your 1%, I say again, you are talking bollocks.
Someone drinking an average of 6x 33ml cans of 4.3% beer a week would not be called an alcoholic in any normal conversation. That's 4.4 litres of alcohol a year - less than half the US intake (9.8l), less than Norway (7.5l) and would fit well in the bottom half of countries by alcohol intake.

The ability to drink other things (scotch, wine, etc) is irrelevant if you only drink beer.
Executives likely have data showing that wfh doesn't work. From a cost perspective, most executives would prefer wfh because
1) the talent pool is greater
2) they can save on facility expenses
3) they can dramatically reduce compensation

Over time (1) and (3) could see compensation easily halve as supply of developers becomes more easily globalized

Gridcoin and PowerLedger two of my favorite crypto projects as there is a tangible benefit to both (IMHO).
When I did enterprise sales, we had another phrase for that: "No one ever got fired for buying IBM." (Coincidentally, I also worked for IBM, back in the day.)

While it's true that tech choices are signals that enterprises do use to determine quality, if you are relying on a particular choice of programming language to sell into major enterprises that's simply a mistake. (And enterprises have invested vast sums in technology written in c# or PHP, so clearly it's not all "lol" out there.)

Rust's and Go's capabilities of compiling into a single binary, without requiring a JVM that needs to be fed and cared for, make them a particularly compelling choice for enterprise deployments. Kubernetes itself is written in Go.
The big issue for me has been lack of travel to events, etc. and almost complete lack of social activities (have had some small outdoors get togethers).

But even though I'm just 30 minutes from an office, I didn't even have a desk there any longer even pre-pandemic. The teams I work on are highly distributed anyway. No reason for me to drive 30 minutes into an office.
I think this is the preprint article: https://arxiv.org/abs/2004.02266
Now that we've discovered that, I'm afraid the entity running the simulation just thinks "13.8 billion years before it happened", hits Ctrl-C and restarts with different initial conditions.
These commands should be also provided behind an 'advanced' submenu which would make them both discoverable AND not used by default by normal users.
I'm a bit confused: does the manufacturer provide a toolchain to compile and run binary code on something that is not advertised as a SOM/SOC, but only as an lte modem?

It’s worth noting that HTTP itself has unparalleled performance for the Web due to the protocol itself (and web servers that deliver it) being optimized over the years to support compression, transfer encoding, encapsulation, etc.

Gemini also transmits a mimetype that’s text-based (text/gemini) but it runs on port 1965 — as opposed to the usual 443 (HTTPS) or 80 (HTTP) that Web browsers usually connect to by default. Gemini therefore needs customized “browsers” that will read the protocol and parse the data that’s received from a Gemini server, however there are Web Proxies that do this as well [0].

In that sense, it’s an alternative to the Web inasmuch as it’s an alternative to HTTP; but (importantly) without any maturity, performance, or scalability whatsoever.

Now to be fair, Gemini doesn't claim to replace HTTP in any way; being a niche, small-web technology.

But in my opinion it's pretty pointless since it uses a strict subset of the HTTP spec which makes it feature-delimited by design.

Using HTML sans CSS/JS will give you a similar yet better experience.

During a massive migration to a different device management service I opened my CSV and saved it as xlsx as the site didn't support csv. Instantly 12% of the serial numbers had their leading zeroes removed and needed a corrective action. ~1800 devices.
If someone has the level of processing power to get a majority of a project's tasks, I think it would go very quickly noticed, and the project admin can just up their task validation higher making it much harder (e.g send to 4 random clients instead of 2). If they were to try to abort a bunch of the work, it would almost certainly get detected automatically by the project's spam protections and they would get less work sent to the point of no work if they do it too much. As well you'd have to pick only a single project which only accounts for 1/19th (currently) of Gridcoin research rewards. Seems easier to just do things legitimately if you have that level of power

The main way you could really pull anything like that off is through a bugs or miss-configurations on where work is sent, which did happen once on a single project that messed up how work was sent, but was fixed rather quickly before they ever got any Gridcoin. As well, Gridcoin incentivizes people to look out for it since they are competing against any cheaters. If a project didn't respond to any attempts to do this, they can also be removed from the whitelisted projects on Gridcoin if needed

For some comparison points about the level of power you'd need without any bugs, Rosetta@Home has 327,525 tasks currently running in place with an estimated ~370 terraflops of power[1]. Now Rosetta@Home is one of the more competitive projects due interest in their COVID-19 work, but overall there's still a lot of computing power in BOINC and from people earning Gridcoin for running BOINC.

I believe there's more to the verification system, but my that's current understanding of it.

Romance of the the Three Kingdoms
I have only very rarely used environment variables in my own software over the last 20 years. The argument for their use that I have heard the most frequently has been "you would have to be an idiot to not use them" which has thus far failed to convince me. That, and its little brother "you must never have pushed anything to production" seem to find some echo in this thread.

From what I could gather, the actual reasons that Other People use environment variables seem to be:

- Other People use some tool for a reason unrelated to environment variables, and that tool happens to make environment variables extremely easy or convenient. A more pessimistic alternative: that tool makes everything inconvenient except for environment variables. Whatever that tool may be, I suspect that I am not using it.

- Other People write programs that are invoked (I write programs that run continuously), and environment variables improve the ease with which programs can be invoked, which is a concept I never have to deal with.

My programs load their configuration from files at startup ; configuration files are committed to git and included in the build ; secrets live in a remote key vault, with a local cache in case of unavailability. Maybe in the future, I will discover something that environment variables greatly improve about this. I don't know.

It is a text editor. A really good one. It could edit files really well last year, and continues to do so really well now. Which possible bugs can be surfaced day to day, or week to week that need fixes?

The S-400 Takes Aim at U.S. Alliances
I've been playing with the ESP32's a lot more recently (which go the RTOS route), and in reading the code for network stacks for these devices, it did occur to me how simple they were in terms of features. I wouldn't say that one needs the entirety of the Linux kernel to be able to implement all of those things, but it does build off of a more well used stack and reuses a lot of well-tested components.

So from this perspective, it's honestly more secure probably, too, as opposed to trusting a hardware company to hire embedded software engineers to reinvent an entire stack from scratch. The latter of which are in rare supply and we all know that reinventing things is a process that often leads to vulnerabilities.

Locking down the communication to just AT commands then makes sense for similar reasons.
I find it amusing that this new meaning is exactly the opposite of the way it’s used in statistics.
