Howdy, digital forensics software developer here. A few points: 1) yes, the police probably should have put the phone in a Faraday bag, but those aren’t perfect and municipal law enforcement generally doesn’t have the same equipment that state and federal police do. It doesn’t excuse the suspect allegedly taking action to destroy evidence; 2) this is probably about the boyfriend, who they suspect committed a shooting—-they charged the girlfriend with evidence tampering as a felony, and then the prosecutor has legal leverage to get her to testify against her boyfriend and take a gun off the street; 3) no amount of technical argumentation will save you from a prosecutor, judge, or jury if you do something that causes spoiliation of evidence—when your company is sued and your business systems are preserved/collected as a result, don’t even think about getting in the way.
This probably won't come as a shock to anyone, but I have noticed more convenience foods being sold by supermarkets over the past several years. Things like trays of freshly prepared pre-seasoned food you just throw in the oven. Anecdotally, this seems much less expensive than services like Blue Apron even if it does force you to go pick it up yourself. (Then again, there's always Instacart...)

You should not solve those problems for her anyway. Help her with tools and such where necessary, but let her figure it out as much as possible. Don't do homework for her, it beats the purpose.

If the course is any good, the answers to questions are going to be easier when you attend lectures etc. If you cant see them, maybe let her explain you what was said there. Explaining someone helps to understand, so it alone would help her a lot to learn and understand.
> you really master something if you have conscious control over it.

Quite the opposite - you master something when you can do it automatically, i.e. without conciously controlling it. The conscious mind has many limitations, one is that it's way too slow to handle real-time events - you can't consciously think about what actions to perform when you suddenly skid your car in a curve, or when you're performing the high jump on a sports field. The other main problem with the conscious mind is that it can't multi-task. So you use your conscious mind to practice, carefully, slowly at first, one part at the time, until, finally, your unconscious (or automated) trained sections of your brain can do it for you, and all the conscious mind has to do is to sit back, relax, and be the conductor. Or just watching.
Not only that, but for $10/serving I can usually find a good cut (filet or ribeye) of steak on sale and a fresh veggie like asparagus. If I want to save money, chicken breast are on a permanent sale of 1.99/pound at my local grocery.

Totally off topic, but I can never quite get over how ridiculously cheap food is in the US.
Even worse, it encourages cargo cults. Conspicuous busy-ness. Jargonized writing styles. Watches that are expensive because no one wants a cheap watch.

The writer is observing something, but the causality is wrong. People read hard to read stuff because it's good. It's not good because it's hard.
i don't understand how this can be an argument regarding the 5th amendment right against self incrimination if it doesn't address schmerber vs California (https://supreme.justia.com/cases/federal/us/384/757/) which found "Since the blood test evidence, although an incriminating product of compulsion, was neither petitioner's testimony nor evidence relating to some communicative act or writing by the petitioner, it was not inadmissible on privilege grounds."

I'm not an expert, but I'd note that Fisher Vs. United States which gets brought up several times was about the accused individual's lawyer producing documents the individual had given them. And a large part of the judgment in the case is the difference between ownership and possession (as seen in the decision of couch vs. united states which it relies on).

In any case fisher said that you couldn't be compelled to testify to affirm the truth of the contents of the documents sought and that the password would decrypt them. But decrypting files is affirming a truth in the documents sought, as the government lacked testimony of their encrypted existence on that hard drive and of the passwords ability to unlock them.

> there’s a world of difference between automatic updates from e.g. Debian and automatic updates from Mozilla.

In what way?

This is obviously somewhat anecdotal, but...

I'm the developer of Heimdall. Software that flashes firmware onto Samsung phones. The software quite literally has the ability to replace almost every piece of software running on your phone. If it were compromised, it could not only own a user's phone, but also potentially everything a user accesses on said phone.

Sure my software is open-source, and I encourage anyone interested to inspect the code, I'm sure there are bugs. However, the `heimdall-flash` package in the official Debian repositories... I didn't make it, and I have no connection with whoever did. Now, don't be alarmed, despite being several years out of date, to the best of my knowledge it's a perfectly good package, and I'm thankful that the maintainer went to the effort. However, it would be so easy for someone to have published a malicious package. This is pretty powerful software, it has significantly more power than root on your mobile phone.

I love Debian, both philosophically and in practice. But does it really deserve your trust more than Mozilla?

Yes, but that's my point. Where I'm currently living (UK, south coast) it's 15C at 77% RH outside, so to get below 50% RH inside the temperature needs to be at least 22C (which it isn't). It's not uncommon for the humidity to get up to 80-90% RH when it rains, and the temperature doesn't drop much.

When it gets to the cold part of winter it's obviously easier, but this time of year it's hard to get it below 50% RH inside just by controlling the temperature.
Same reason preventative medicine is not practiced. The upfront costs are great and the out come not certain leaving many hesitant to invest in something they may never benefit from. Especially if your country has more immediate pressing matters that you could fix right now with that money.

The writer has tested a lot of combinations of fans and filters (Simple, HEPA, Activated Charcoal). It's astonishingly easy to build a combination that costs way less than a "professional" Air filter.

The writer has put his findings into a "social startup" that builts these simple, but very effective airfilters in some developing countries:

This interpretation of the right to remain silent frightens me.

The example I was always given to point out the need of such a right is the police saying, "Alright, show us where you buried the body." And if they can "prove" that you buried the body but you cannot actually take them there because you didn't bury the body then you go to prison forever.

The government should not have the power to go on a fishing expedition through my device. If the government can already prove that something illegal is on my device, then they do not need that thing in order to convict me of a crime. It is just superfluous to compel me to do things and it is dangerous.
Controlling magnetism opens route to ultra-low-power microchips
I think this is an often understated point when discussing meal services. In my experience with Blue Apron and Hello Fresh there were some good and interesting meal choices (often ethnic dishes that I hadn't tried before), but probably 50% of the menu boiled down to simple dishes like "some variation of spaghetti with salad" or "chicken breast with a simple sauce and basic veggies." People who already know how to cook are going to realize how much they're overpaying for these simple dishes, and people who learn to cook thanks to the service will come to realize it unless they avoid the grocery store entirely.

Ultimately the complex/exotic dishes just aren't offered enough to offset paying $10/ small portion for the more simple dishes.

I believe they’re solving a real problem. For people that want a healthy meal but don’t want to spend $ on farm to table type restaurant. Although I do see quite a few more healthy options sprouting up in NYC I can’t speak for more suburban areas. Point being is a lot people care about ingredients, food prep (i.e. those brussel sprouts are not that healthy if cooked in re-used vegetable oil).

The tricky part with this business model is making the food taste good is an art form and not easy to boil down to a simple 9 step formula. Also difficult is keeping all the ingredients fresh and portioned / ready to cook while keeping the price lower than it would be to go out and eat.
More of Electron Enhancer, really.
Right, but the person I was replying to was comparing it to prepared food.

I think more Americans may eat prepared food more often than you think (and Blue Apron or similar services are usually 2-3 meals a week, which is far from every meal).

But I agree it looks like the price they would need to charge to be profitable is not a price there is a sufficient market for.
In a weird way I kinda like these totally mental systems. It really ups your skill level for debugging if nothing else.

I've worked with lots of proprietary CMS systems and I kinda got into a groove with working with them. I knew exactly how to manipulate the system within the parameters of said system.

I kinda found it challenging. When a system is well built. I find it boring.
Everyone's on the same 2 month like schedules, so I guess that won't be much of a problem.
To evaluate whether this will work in practice I looked to the actual FDA and the Patent Office. The FDA: budget issues, understaffed, susceptible to political attacks. The Patent Office: budget issues, complete lack of ability to make fair and balanced decisions on software patents (e.g., the linked list is patented by Google, https://patents.google.com/patent/US7028023B2/en). I also am concerned with the broadness of algorithms. Better might be if we restricted it to algorithms in applications which could affect human safety or financial transactions. Still, given the past examples, I'm doubtful this would work well in practice.
What we need is a winner in the C++ package manager wars, then adding such dependencies wouldn't be such a big issue.
Well I think that it mostly depends on what you order. Fancy restaurant will have expensive fancy food but you can often find more reasonably-priced offerings (in my experience Asian restaurants are pretty competitive). After that it mostly depends on the delivery costs, obviously if you order for one it's a non-negligible amount but for two or more it becomes very small.

I have a whole load. (-:

Recent does not always equate to better, note. There are exercises in Bach that are still relevant today. Milenkovic's 1987 book has a fairly interesting angle on design that one does not find elsewhere.

And several comparative operating systems books do not have the wide range of case studies that such books used to have.

That said: There are some interesting books on Solaris and MacOS internals that I did not have (and indeed that did not exist) when that FGA was written. The Windows NT Internals book is now two books (parts 1 and 2) and on its 7th edition (with a slightly unfortunate cover design, per https://news.ycombinator.com/item?id=14321672). And of course there is a FreeBSD D&I book.

I've also bought an interesting old book on VMS internals, since then. It discusses ODS.

Robust takeout is not available in my region. We're a busy family, like all families. Both my wife and I hate visiting the grocery store, and find Peapod delivery to optimal.

I also wouldn't make the assumption that people like us, and the OP "don't care about ingredients". We just don't believe, like some do that our choices in ingredients will really matter that much. The ingredients our delivery guy brings us are the same as what's available in the local grocery store, we've never had bad ingredients delivered, and if we did it's easily sent back/refunded.

over a year ago, the rapid fire, almost daily updates to their android app had given me the suspicions that their operating expenses would be too much to remain humble for long, then came the notifications and social media posts inviting me to come read the paywall articles. I'm not against paying for access with subscription, as I have a few, as well as a healthy list of creators on Patreon but I feel it's kinda like YouTube profiting massively from user generated content. I know they aren't in it for fun, just saying it's been obvious for a while now
My words were harsh and I probably deserve the downvotes. It just appears like it is getting ever more evident, that chess results in a draw assuming perfect play. That doesn't diminish the accomplishments of world class chess players in any way, but it feels like there is a reachable skill cap allowing black to force a draw. I'm not even sure if it's possible to design a "fair" game, which always has a winner, assuming no randomization. Go is most likely closer to that goal than chess, as it always has a winner and allows to compensate for the first-mover advantage using a score bias. Then of course finding an optimal value for the bias is a hard problem.
We recently got a Winix U300 (1) for about £150 new. It is basically a HEPA + Activated Charcoal filter and it claims it has some "plasmawave" thing that generates "free radicals" that kills odors and viruses. Initial searching suggests that this might be true, but I am unsure if there is any way to really test it. The air quality sensor certainloy works if you drink a strong coffee then go and blow into the sensor - the fans crank up the speed hugely to compensate for the stinking coffee breath! :)

Only criticism is that the U300 does not have wifi connection - only IR control... I am hacking up a esp8266 + some IR LEDs and photoresistors to monitor and control it via MQTT though which is fun. The "wifi connected" units seem to add several hundred GBP to the price for the same filtering performance.

We're not sure if we're noticing any actual improvements in air quality, or just imagining it...! :-) The placebo effect is quite good if nothing else. Noses feel less congested, and the air in the room feels less stuffy in the morning.

Acute Flaccid Myelitis (updated November 13, 2018)
I live in New Jersey, and work in New York City. I leave my desk at 4, get home 5:15-5:30, and I like to cook dinner when I can.

I also have a 3-year-old, and keeping on a routine is something I feel that is important, so dinner on the table by 6 is my gold standard that I really really want to have happen as much as I can (allows bedtime routine at 7:30).

I often buy pre-chopped veggies, as long as I trust the chopper (there is a little farm market down the street from me and I see them chopping in the back room). The time it saves is great, easy 5 minutes closer to dinner time than I'd be otherwise, not counting the extra cleanup.
Driving is a perfect and mundane example of unconscious competence most people have. If you could perform with the simple confidence of driving to work,you would probably be very good at what you were doing.

A friend once rhetorically asked me what trying to be funny meant, and of course it means being not funny, yet when we want to achieve some other end we approach it by trying. Yoda summed it up well, but we don't really get a chance to understand what it really means. Trying to drive on a highway is farcically dangerous, but simply driving on one is among the safest ways to drive.

There is a mental change that comes from physical competence where you no longer fear failure, and I'd argue its that lack of fear that makes the difference at elite levels where skills are largely equal. It also makes the difference in the rate at which you learn. The try/humiliate style of teaching is a way to produce industrial scale mediocrity, and so few can appreciate the difference that there is often no reason to change.
I think there are a number of startups building on the foundational research done for the other, larger experimental reactors that are trying to build small-scale fusion reactors, some with quick iterations on their designs (i.e. a reactor generation only takes half a year instead of 15 years). Some of them are based near the JET lab, afaik. TAE Technologies also has an own approach for example.
> I'm a programmer and have been for around 5-6 years, I started with VB.NET since I first started learning, then progressed onto Web Development at a large agency for 4 years (PHP, JS, React) and I'm now back with VB.NET.

The running joke amongst "real" developers with CS background is that VB or web developers aren't real developers.

> It makes me question how I was hired in the first place.

Because your job require you know basic CS material? As long as you get the job done, that's all that matters.

> Sorry for the rant, but I was just wondering if anyone else felt like this.

I personally haven't because I have a CS degree but I'm sure many have. I've known musician, construction workers, bartenders, etc working as VB or web developers. As long as people get the job done, nobody really cares.

I wouldn't get too worked up about it since you are at a point where interviewers will never ask you basic CS questions.
Holy fuck I'd work for you in a heartbeat.
I'm a little annoyed by the people who call these simple problems. There are no simple problems. Calling something simple is very insulting and demoralising.

It really depends on your experience and knowledge for what is simple for you.

You can have 20 years of experience developing projects and acquired a ton of valuable skills but when I shove a whiteboard in your face and tell you to solve some algorithm it's completely new and not simple at all.

Just as someone with a lot of theoretical CS knowledge will struggle if I present them with a failing dependency tree of 30 thousands NPM packages. Good luck solving that when you have never done it.
Only as much as cost/benefit of all this helps the company. HR is not a union. It literally has "resources" in the name, said resource being you. Resources get written off, used up, sold and discarded as a matter of business practice.
