Just watched this episode. I didn't take that "revelation" at the end to mean he actually did that. Saw it as just the final "lulz" move in the trolling.

As an embellishment by the trolls, it would probably move any authority figures from a position of "let's figure out who got this dumb kid mixed up in these terrible things" to stony indifference and something closer to "serves him right." It also alienates him from his family so he has nobody in his corner any more.

Consider your own reaction as a viewer. Think about the other person who was involved in the last task of the episode. Did you feel any sympathy for him?

SOME ADVICE BEFORE YOU DO A DEEP DIVE INTO WHATEVER YOU END UP STUDYING MATH-WISE:

My Background: Current Undergraduate in CS and I recently added Mathematics

The most difficult part for a person who hasn't done a lot of math to become a person who does a lot of math is to read and understand rigorous proofs. You will encounter countless difficult proofs in any mathematical topic you try to study. Read a few books on mathematical thinking and proof techniques before/during/after reading any other dense math book.

Like you, I realize the value of having a mathematical mindset and want to have a deep understanding. When I added math as a major, I had a very hard time jumping from computational courses (typical math courses, geared towards any major) to theoretical and conceptual courses (proof-based courses that use all the fun and interesting math books everyone has linked here). These books helped:

I'm wondering how the user KMinshew was the top job poster for the year when the most recent comment of theirs was from 2014.
Disclaimer: I currently work for a genetics genealogy company mentioned in this article. My comments are my own. Some relevant previous comment threads of mine about other DNA related articles: [0], [1], [2], [3]

Personally, I would love to help create legislation aimed to protect consumers from perceived and actual problems related to DNA sequencing and analysis. I don't know how though and I fear it'd fall to the back burner in the current US political climate. Our customers are not only US but international though and that presents yet another dimension to the challenges therein.

This article states:

> Whatever your ancestry results, don't get too attached to them. They could change.

That is absolutely correct. I've stated why in a previous comment [1]; Some DNA analysis software employ stochastic algorithms. That means that the answer they provide can be different if run more than once.

The article also states:

> Despite the popularity of ancestry testing, there is absolutely no government or professional oversight of the industry to ensure the validity of the results.

That is also correct. I've heard peers state that the industry isn't regulated outside of the field of medicine during product discussions. I think that's something which needs to be addressed: leaving it unaddressed can encourage predatory business behavior.

First I think you need to think about a direction. "Learn Math" is a very broad and vague statement. You will never learn all of math. So you really need to think about why you're wanting to learn it, and pick a direction that suits that.

If you're wanting to learn math just because you like the subject, then it's wise to get a sampling of a wide array of different areas. Then you have a better chance of finding an area that you like best.

If you're goal is to learn it so you can apply it in some other area, you should focus mostly on learning what math applies in that area. Then find the prerequisites and start studying.

Studying alone in your spare time will be nothing at all like attending a university. The full immersion you get to focusing primarily on one thing, and the ability to engage others at will also focusing on the same thing is a great help in learning. So set your expectations right. You won't be able to reach the level of understanding a 60 year old math professor has. Since he/she has been fully immersed in the topic for probably 40-50 years. So set your expectations accordingly.
yah, the money has to come from somewhere and texas has a lot of roads and schools (in a prior job, texas used my product in it's property tax assessments).

i think the focus on low taxes is born of a frustration with corruption, inefficiency, and unfairness. so let's hold elected officials to those standards rather than focus on tax rates, which is both a proxy and a distraction (also true of the 'small government' talking point).

Two years ago when we checked out the DASH and HLS support in Edge it turned out to be so unreliable we still just went with Shaka instead.

Fun fact: besides FairPlay compatibility, HLS in Safari is way more annoying to deal with than HLS via hls.js in browsers that don't natively support it. Safari provides you way less information about what's happening stream/buffer wise, and if you work with HLS event streams you need a ton of hacks to make it behave correctly.
I sure wish they'd make it run as a first class citizen on Mac, currently it uses XQuartz and I'm constantly having it open a file but I can't get to the windows: they flash, then go to some hidden desktop and you have to jump through hoops to try to get them to actually display. Horrible user experience and I have given up on recommending this to other because they all run into the same thing and get frustrated and give up.
On top of that even if they were able to sequence things perfectly the thing they are actually measuring is a very fuzzy thing. Like it's no surprise that one of the test had one twin from England but the other from Scotland/Ireland because people having been moving between those 3 countries for millennia so there isn't really a platonic idea of 'English DNA' it's just markers that tend to show up in England, but also show up near England but somewhat less and may also randomly popup other places, but usually not all of them in one other place.

From what I've observed, most engineers are glad to be done with math when they finish college. Most engineering is qualitative: Organizing and arranging things, making things fit together, and troubleshooting. Maybe 10% of engineering is quantitative, and that work often goes to the handful of people in the department who have maintained an interest in it.

Some of the engineers who attract quantitative work are people who came from outside of the mainstream engineering training, such as scientists and math people.

Ask HN: What Is the Best Tool for Time Series Graphing and Forecasting
Hey HN community: I am working on a project to Graph time series network performance and need it to Forecast and Trend to an Enterprise Web page. What is the best tool for this in terms of good results, relatively easy to use and set up ?
Thanks !
Most decent CAM software has at least some simulation routines, which is helpful, but definitely not definitive. There can often be errors such as defaults that are bad in some situation that create a lead-in/out that tries to clear the tool, but actually digs the full length of it into the solid material, and this might not be noticed in the simulation.

I've also frequently mocked up styrofoam stock material and run the entire toolpath through that, which can be very helpful, but again, not definitive.

Ultimately, you need to just be really careful about the toolpath creation, and watch the first run like a hawk, which can take hours. Pausing and starting each new segment at a fraction of normal speed can help also.

The cool thing is that once you've run the toolpath a few times and can trust it, you can almost start it and ignore it while the part gets made (note that the operative word is almost).

Even with the difficulties, when you have a good machine and some skills (and patience), it is quite rewarding what you can make!

"Acid3, in particular, contains some controversial tests and no longer reflects the consensus of the Web standards it purports to test, especially when it comes to issues affecting mobile browsers. The tests remain available for historical purposes and for use by browser vendors. It would be inappropriate, however, to use them as part of a certification process, especially for mobile browsers."

DNA microarrays do have limitations vs. RNAseq, but they are accurate and repeatable when used properly. https://en.wikipedia.org/wiki/DNA_microarray Calling them 'super error prone' is simply inaccurate.

There was a good 5-10 years where microarrays were the go-to method for genomic investigation. Since RNA-seq has supplanted it, there has been no revolution in overturning those old results. At best, RNA-seq reveals what microarrays cannot: novel sequences, specific sequences that have difficulty hybridizing, etc.

The variation between these services is due primarily to how the data is interpreted and presented to customers, not the reads themselves.
Yes it does. They are selling it as DNA = Ancestry. For me, that is blatantly misleading at best and fraudulent at worst.

Being able to have prototypes in hand in like 30 minutes is the best thing about PCB milling. You can make boards for fine pitch parts as well - the board has to be probed and leveling applied to the GCode. We're using 3040Z CNC which is not the best for this job but manageable.

Just be glad your number is not being used as the spoofed number. Had this happen to a coworker. He was getting hundreds of calls, voicemails and texts from people wondering why he was calling/pranking them. I assume some people just saw a missed call and were curious or have a business reason for returning missed call. But its amazing how many people don't understand what was really happening, including people angry with him. it's gradually died down over a few weeks. Carrier support line implied there is nothing they can do.

Just my own opinion, but at this point I think it's prudent to assume that pretty much anything you send out into the digital network world is public. If it's not something you would want the world knowing you said, don't put it out there. Security breaches happen. Bugs happen. Sometimes law enforcement just comes by and says, "Give me everything that user X has ever done." In short, sh!t happens.

"Everything I do on the net can be authoritatively attributed to me personally."

That's the thought we should all have in our heads before we send any post, or send any text, or send any email, or send any photo, or etc etc etc. We shouldn't rely on some company, that's using us to make money, to protect our privacy.

That's not strictly true. The recent wars weren't "declarations of war", but most (not all) were authorized by Congress. Congress voted on military action against those countries and it passed both chambers, but they didn't "declare war". To be honest I don't understand the difference, other than the words used.

> Historically monopoly was about granted status

Historically, monopoly was about single players taking over the economic system. There are other, better words to use if you aren't describing ONE powerful company.

Carnegie Steel Company. Rockefeller's Oil. Ma Bell. ONE supplier, across the entire USA.

You're not winning this argument from etymology (where Mono literally means one), or historical. Ma Bell's breakup was as recent as 1980s, this isn't some "ancient history" here, its modern US history.
This has been the event that has finally convinced my wife to use a password manager. I'm torn between bitwarden and 1Password though. Anyone care to weigh in on the options? My biggest concern with BitWarden is the lack of automated testing

I wholeheartedly agree with your analysis on the risks.

This is probably never going to happen... But, IMHO, I think the best way would be to implement a very small fee for each call placed. Even if it was a penny or a few cents, most people, if not all will never feel that but it would put most of the robo-callers out of business since they place thousands if not millions of calls per month.

I don't know because this isn't my area of expertise, but when I use my Firefox browser to load the page with the developer console open, it throws two XML parsing errors.

So I figure it's one of three things going on here. One, modern browser makers just don't bother testing Acid3 anymore, and bugs have crept into the browser. Two, modern browsers knowingly break Acid3 because they prefer to implement performance enhancements that are not strictly compliant with standards. Three, updated standards have added syntax or rules that invalidate some of the strange stuff that is packed into Acid3.
