Really cool! I wish more universities included this sort of training during their undergraduate ECE programs.

Also worth noting (didn't see this mentioned in the article, and maybe this is obvious...), it is usually wise to make your prototype on a breadboard/perfboard first, before ever printing a run of PCBs. This is especially true if your board is interacting with other parts of a system (E.G. you are building a power board for a robot). This let's you get a proof a concept working right away, and helps ensure no unexpected integration problems crop up that might call for a redesign.

Ask HN: What is a lightweight web framework?
I'm building something targeting legacy devices. The devices are run on an old Webkit, able to run basic HTML/JS/CSS but not even things like CSS3.

We tried Angular 4 but it was too heavy. It does run with Node/express hosting a HTML file. What are some lightweight frameworks we can use between this?

Rebalancing cryptoassets on the same exchange (without withdrawing to a wallet [1]) doesn't require on-chain transactions. The fee would be the order fill fee, which for GDAX is 0-0.25%, much less than 2% of the account balance.

Wars always have casualties. Technology helps to reduce them. In WW2 it was normal to wipe whole cities using bombs.
It's an interesting fact--anecdotally, of course--that as much as they complain about the country, they won't let anyone from outside to do the same thing.
Microsoft also makes a lot of great ergonomic equipment that are priced mid range.
Wow, that doesn't seem wise (at the first glance). These market caps are really easy to manipulate, especially when you only have to do it annually and the exact time is specified. Huuge shorts. Bonus points for doing something like BCH before that to force your coin onto Coinbase (because otherwise people are gonna complain Coinbase is stealing their coins from the forked chain).
You'd also have to fake the stars in the night sky and trick everyone to not notice the timezone didn't change. Probably easier to fake a moon landing.

The biggest problem is the query language. Without a query language, a company must hire and keep on-staff a developer who can help express problems to the database. Time after time people told me that they ended up with giant databases and needed to run lots of ad-hoc queries or generate reports from them. Once a time-series database becomes the system of record for important information, it needs to be queried for everything from invoicing to analytics to troubleshooting. In practice, larger companies end up with at least two full time developers who write applications to produce answers from the database. These are answers that the business/marketing/ops/whoever should be able to get themselves by just running queries. As time passes, this is both a huge cost and a bottleneck.[0] Link [1] goes to the archive mirror.

Rebalancing is the correct term of art here. The index reweights, the fund rebalances its holdings in order to track the new reweighted index. Source: traded a lot of index funds.

Also, based on the blog post, the fund (or the index managers, who are the same people here) would say they are rebalancing in your sense of the word too. They are adding diversification compared to a portfolio that just holds, say, bitcoin. Sure, it's not as diverse as one that also holds stocks and bonds and real estate, but nobody's perfect.
Assisted Living: 7 Answers to Common Questions
Oh that's cool, but I have an Android. GPS drains the battery.
Nice. You could wrap all that up as a service for $500+ perhaps?
> With that specific number, I am guessing it is indeed a requirement.

I'm guessing here, because the language is ambiguous and the relevant states & laws are not mentioned, that the legal obligation exists if you should find suspected child pornography you must report it to the relevant legal authority. I highly doubt the law states something along the lines of if you're a computer repair technician you are legally obligated to run these forensic tools to local clandestine or non-hidden photos that may be child pornography. The former I could see an argument being made that failing to report could make you criminally complicit or even an accessory to the crime. The latter, I see as possible 1st or 4th amendment violations to the US Constitution (1st amendment violation in that it's possibly compelling speech, and for the 4th, the DOJ compelling a warrant-less search. By virtue of offering the bounty in this manner, it could be argued Best Buy is effectively acting as a page contractor of the DOJ).

Obligatory, I am not a lawyer. I'm merely speculating on possible legal arguments.

Morally, I'm torn on this. On one hand, I find child pornography morally reprehensible, yet on the other hand, I want these scum bags thrown in a dark, dank prison. In the end, I think, however, that this should constitute a 4th amendment violation. If this is to stand, what's the rate to be for the government to get anything they want to know about me? $100? $.01? gratis? any IRS inquiries to disappear? I think we need to revisit the 4th amendment to give explicit protection to data held by an external party.

Hey HN,
I made this project during a very difficult time of my life. I was unemployed and was having a non stop roller coaster in my marriage. This project was created due to my own frustrations of having multiple tabs open of articles and not reading them ... and just hoarding on tabs (some have been open for 2 years). This is the first iteration. Any constructive criticism is greatly appreciated. Any suggestions are also welcome. Also awaiting any other comments.
A Tiny Wolfenstein-Like Software Engine
Reading the weighting section of the index fund ( https://am.coinbase.com/documents/cbi-methodology.pdf -- linked in a few sibling comments too) the following statement, while standard language and approach, makes me wonder in this case:

"The market capitalization of each constituent asset is calculated as the price of the asset multiplied by the supply of the asset."

There are always some small mistakes in the supply of the asset. Bitcoin however has a considerable amount of lost coins. This has been discussed a lot and there are a couple of studies out there (here is a quick link via fortune (placeholder till I find the original study): http://fortune.com/2017/11/25/lost-bitcoins/).

They seem to ignore this fact in their calculations (they follow a fixed supply approach it appears. Does anyone with experience in investing have any opinion? Shouldn't indexes at least attempt adjustment?

Note paragraph 2.10 mentions that no supply adjustment ever is going to be made. I think this considerably inflates the nominal value of the fund (for the eyes of the world). Thoughts?

The research is very good that, beyond basic nutrition, very little by way of environment has a significant effect on adult intelligence. Outcomes, as you say, are a different thing and you can teach people to have lower time preferences, increase conscientiousness, etc. but, unfortunately, these are typically not what we focus on in todays social interventions.
> while patriots defend you and do the hard work of defending freedoms.

You probably don't realize that there are war veterans, and active service members (e.g. National Guard, Reserves) working for tech companies like Google. But then again, such realization would be a real downer to your agenda.
You're referring to the tragedy of the commons I believe. So the simple answer is that they might not, and so perhaps there's a role for government oversight/requirements similar to safety requirements. It's not a stretch to consider this a safety issue, if only for the other human-piloted vehicles.

But I think it could be in a private company's interest too. Better road conditions would be better for wear and tear on their vehicles. Lower maintenance costs on the road should result in lower tax burden for the company (assuming company pairs fair share of their taxes which admittedly may not be true).

Cost of software improvements like this scale well (ie cost is distributed over time and customers well). In fact the vendor of the vehicle could present it as a competitive advantage over other vendors that don't address it in any way.

I wasn't thinking the solution would be based on sensing the build-up of lane wear/ridges, I presumed the solution would be something along the lines of varying their lane position to avoid the specific case of always travelling in exactly the same spot in the lane. With some randomness I don't think it would take inter-company cooperation. Just the idea that if the same vehicles were travelling the same route, that the wear on the road would be reduced by some amount. Obviously this is a lot of armchair architecture-ing from some random front-end UI developer, but I think it's not unreasonable to think along these lines once they reach the point of optimisations. Fun to think about anyway.

If you want to work in Engineering knowledge of trig is a must have.

For instance calculating the deflection of a structural beam as you load it with weight (a discipline known as statics), depends heavily on trig. Anything involving rotation and angular momentum (such as gears and axles) require knowledge about trig.

Other than that triangulation- computing the distance between points is a useful practical application.
I think this is a good example of how their old ethos of "Do no evil" was a narrow-minded fantasy by privileged white people who never had to face the world they were born into.

Sitting in your expensive apartment (raising rents so that the former neighbors can no longer afford to live here), sipping your Starbucks (a global commodity dependent on trade deals to somewhat stabilize paying farmers around the world about a dollar a day), eating your Blue Apron salad (sourced by illegal immigrants who have to work for peanuts with virtually no rights or social services because their livelihood is constantly in jeopardy), sitting at your desk in your clothes with your gadgets (which were all made overseas by poor people for pennies in order for them to send money back to their families), tweeting away (absorbing and perpetuating the consumer-driven media machine infused into all of our lives).

We do evil all the time. Then the military comes along and says, "Hey, remember how your silent consent helped a political machine fight wars built on lies to drive poor Islamic people to want to kill and drive out any foreigners from their countries? We need you to help us kill them now." And you say, how dare you.

Romans lived a pampered privileged life that was literally only logistically possible by an army of slaves doing everything for them. We're not so different - the slaves are just less visible now.
In my experience, employees seem to have an uncanny ability to annoy me when I just want to browse, and avoid me when I want their help.

Out of the last 5 times I've gone into a store hoping to get some help and advice from an employee, I reckon 3/5 they have ignored me until I found what I was looking for, or concluded that they didn't have it and just left.

I've even put my hand up in the middle of a store, like I was in school, waiting for assistance because ther were so few employees around, or because after asking me if I needed help as I walked in the door, they lost interest in me, and decided to have a chat with their colleagues.
For comparison, this is a calculator that was built by actuaries[1] for the Australian market:

https://supercalcs.com.au/ris9/mst

Some really important things that are built into it are:

- Everything is given in "today's dollars" and that's done by reference to a salary index, NOT a price index, to reflect increases in community living standards.

- It shows some indication of the income level you can expect during retirement given your lump-sum retirement benefit.

It’s been shockingly easy, actually! I do relatively few orders (2 per month) and can get a record of my filled orders [0] on the day I know my buys will occur.

I plug those automated buys into a spreadsheet where I maintain a record of my orders. That spreadsheet does a FIFO capital gains calculation, and I’m good to go.

I must admit, I haven’t sold yet, so I may just be niave about how 2018 taxes will go!

Seeing this from another perspective, shouldn't Reserve's engineering team have been able to pre-empt this kind of attack? If they could do a postmortem and determine the requests came from a single range of IP's (assumption), they could have foreseen it. Or if they had set up alerting around frequency of reservations, they would seen an outsized number of requests which they could further look into. These are pretty easy to set up, so I'm surprised they're so naïve about this kind of vector.
That less than three image requirement seems really strict. If my browser were to simply pre-fetch a child porn site, I would probably have more than 3 illegal images on my computer.
Is there free software to create and simulate virtual populated PCBs? Fritzing allows creation, but it doesn't simulate the board.

For simulation one needs the exact behaviour of all parts. That excludes board with parts that have a closed design, or insufficient documentation. But for many parts, and hopefully soon with CPU-ICs thanks to RISC-V, we can do simulation.

I don't expect real-time simulation, but at least a solution for letting the machine compute over night to see if the board successfully does X.

Any suggestions? Is this a problem waiting for a solution?
By having an index fund, are they saying crypto investing is safe now?
More certainly have parents that care and read and show read is good is what make the impact.
How would that increase the nominal value of the fund? Worst it would do is inflate the market cap of a specific coin in relation to others, altering the weighting a little bit. They note there's no definitive way to calculate true supply so they aren't going to get in the business of trying to do so.
It might be worth reaching out to Joel at Open Snow (http://opensnow.com/about/contact) to see if they'd be willing to share any of their historical weather data (assuming it's what you need, I don't know the ins and outs of weather data other than being an Open Snow user and knowing they have historical records for snowfall for much of the US).
The string benchmark has the issue that the amount of work done varies with each pass through the loop since the string just keeps getting appended to. A proper benchmark like the ones in the comments here do the same amount of work for every loop.

If they adjust the price of the coins by removing lost coins from the supply (how would they even know with certainty which coins are lost, making this definition on their own would be going against the sanctity of the blockchain) then the price per coin would increase.
> So by your definition, a non-liberal would answer:

1. Abortion is only acceptable in the cases of rape and the mother's life being in danger. Abortion as post-pregnancy contraceptive is totally unacceptable. The correct course is to mandate adoption (in the case the mother doesn't want it) instead, expand adoption opportunity and lower adoption barrier to entry.

2. Patients going through rehab should not simply receive it for free. They should have to "give back" by helping the next generation of addicts via volunteer work.

3. Healthcare should be subsidized more for those who strive to live healthy lives. The people that eat right, exercise, etc, should have higher priority at the doctor and more healthcare-related benefits than people who are overweight, non-exercising, drug-abusing, etc.

4. Financial assistance should not be unconditional. It should be accessible only after the the applicant has gone through financial counselling and taken steps to become more responsible over their finances, learned to budget and eliminate waste from their expenses.

That is how to keep people accountable for their actions while also providing a way out.

While I agree in principle, in practice this implies a maintenance burden. Who should the burden fall on? Some researchers leave to industry positions. Some leave for family obligations.

J Scoggins published an expert system wavefront scheduler [0][1] six years ago. Now, he's working on an expert system processor simulator [2]. Should requests on his earlier work take time from his current work? If he were to release a docker image, or whatever, of his setup while writing these tools is that enough?

Obviously, there's a spot to shoot for between tossing binaries over the wall and a month long sabbatical to write documentation and example code for something no one may ever use.

I have to ask, because I didn't pursue academia. Would you, as a grad student (per your github), reject or welcome a policy that insisted that the last week, or whatever, of the development window is to document the tools of the study?

Traditionally, academic disciplines have stemmed from others via discovery and innovation. There is no difference in academic CS; industrial (software) engineering best-practices, ex. design patterns, are derived from research. I would suggest doing a more thorough search through industry-focused academic literature, and pattern match what you do against findings to find a best match. Additionally, you could pursue a masters/PhD in a lab that does work on that topic (assuming you find something). Alternatively, get sponsorship from a company with resources as was suggested already. Think Bell Labs.

Out of curiosity, what is the general (or specific, if you feel comfortable sharing) area of your expertise? I'm always interested in exciting tech niches.
Nice ideas, and I use a similar setup for my personal domain. For people who don't want the hassle of setting up a domain name, maybe there should be a standard by which an email provider could be queried to find someone's social network account provider.

If your email address were, for example, ocd AT trekk DOT ie, an email contact of yours should be able to make a DNS (or SMTP?) request to trekk.ie and find your social network account ocdtrekkie@mastodon.cloud, where they could send a friend request from their own social network provider. The link between email account and social network account could be checked periodically based on the TTL.
