Just to clarify, the testing device they claim to have invented is proprietary and they have every right to protect their IP.

By calling out the lack of peer review, I'm referring to the science behind the use of fingerstick sampling. When you extract blood from a vein with a sterile needle, the blood is uncontaminated. When you stab someone’s finger with a blade or sharp pin, presumably you have lacerated hundreds or thousands of capillaries. The blood that emerges is contaminated by tissues inside the finger and by oils and bacteria on the surface of the finger.

It’s possible to do simple tests like iron level with this blood and get accurate results. More complicated tests are another matter, and require scientific investigation.
Reducing the discussion to a dictionary definition is emblematic of many of the problems in today's political discourse. This pithy, literal definition of a term is not relevant, especially when that same term, in the same context, is discussed at length, in light of various philosophies on the matter, in the Federalist Papers.

I don't think there's a better source of information about whether the government of the united States of America is a democracy than the position papers written to advance the four corners of its founding instruments, and they deliver an unambiguous "no."

Let's say, for a a moment, that your definition, which seems to conflate these two distinguishable scenarios (one in which a government's power is strictly limited and enumerated, and another in which that power extends to the bounds of whatever a voting majority or their representatives might desire), is a reasonable one.

How, then, do you discuss this distinction?

...and even by your definition, while an individual state might quality, the government of the USA does not: "supreme power" is wholly unavailable through the US government, at least in its legitimate purview (of course it exceeds this boundary frequently and flagrantly). It has dominion only over the specific areas outlined in the constitution; those not mentioned are reserved for the states or the people.
I own a number of old(er) systems programming manuals, JCL books, and even a couple of COBOL handbooks from a few years ago when I was playing around with hercules [1]. I had a ton of fun (from a hacker perspective). I recommend playing around with it, if only to get a look at how different things can be.

Not necessarily wrong, but interesting test case for whether insuring the autonomous vehicle is cheaper then driving the poorly trained driver. Might still have a supervisor, but now they can put their undivided attention on the occupants.
That's a good point.

Kilamanjaro is 5895 metres, and EBC is 5380 metres.

You're correct that in the study, the Kilamanjaro climbers (n=7), most of them came back with normal brain scans. That is definitely encouraging.

Also, I have heard that Kilamanjaro is tougher than EBC, due partly to the rate ascent and people pushing themselves too aggressively - if I was to do EBC, I'm happy to take it slower, to avoid AMS. I'll probably be taking diamox, but I don't know if that makes a difference here.

(I did the Inca Trail to Macchu Picchu with a group, fairly aggressive pace, but it's considerably lower - although I just Googled and apparently the highest point on the trail is 4215 metres, so maybe not that different).

There may be hope yet...haha.

How did you find your trek via Lobuche East? Any ill effects? And you found it easier than Kilimanjaro?
FBI allegedly* breaks into iPhone.
Two questions that I still have on this:

(1) Does the public accept that the FBI is even telling the truth on this (i.e., did they actually "break into" this iPhone)?

(2) If they did gain access to the iPhone's info, was it actually through the use of a vulnerability, or did they discover some other info that led them to the passcode?
The problem with autonomous shuttles on campuses, especially university/college campuses, is that people who are walking can be very unpredictable, and doubly-so if they are listening to music with headphones.

I had a student job where I would drive our golf cart all over campus and it was awful at times when there would be many students out during class change, arriving on campus, or leaving. People don't pay attention or they take chances on their bikes/longboards.
I would say that if a "bad post" has resulted in good discussion, then it wasn't a bad post. It might be in poor taste, but if that is a filtering criteria then you're going to get groupthink around controversial subjects.
I thought this was a parody on pad-left.
I'm sure you are correct about the aliasing being undefined behavior. However, Microsoft's attitude towards certain types of undefined is quite different from the gcc/clang attitude and VC++ (more or less) promise not to break your program if you break the aliasing rules.

gcc/clang are within their rights to break programs that break the aliasing rules, but VC++ is not required to do so and they choose not to.

There have been some excellent articles talking about how the current state of undefined behavior as understood by gcc/clang is crazy. One that I like is this one:
http://blog.regehr.org/archives/761

Obviously some types of undefined behavior cannot be 'normalized', such as use-after-free, but treating the aliasing in that bug as undefined behavior is a committee decision that many developers think is ill advised.

Another recent article that I can't find pokes some holes in the idea that the latitude given to compilers by undefined behavior improves performance.

For your second example of undefined behavior I'm afraid I don't understand. Are you saying that even if the line of code that aliases the array is removed that "if (key[0] != 42)" is still undefined behavior? If so please explain. You say "the type AS ACTUALLY WRITTEN is not char" but I'm not sure what type you are referring to, and if you mean '42' that is true but not relevant because in a comparison between key[0] and '42' "key[0]" is converted to int by the standard integral conversions and then a particularly boring comparison is done.

If that code is undefined then the standards committee is definitely crazy and no code is conforming.

How Pair Programming gave me a life reset
Hi there -- I'm really sorry that you had such a negative experience. It sounds like we didn't honor how much time you'd put into the challenge, and that sucks.

I'd be happy to share more feedback with you if you're still interested, though it seems like you've moved on happily. Feel free to reach out to jack@asana.com and we can talk more.

Regardless, best of luck where you are now.
Can one still see subpixels with consumer Rift as with DKs?
As that was the first thing I noticed, to my shock :)
Interesting to see two YC companies that do the exact same thing in consecutive cohorts. Beside that point though, this is very different from normal autonomous cars. The path is preset and guided using GPS and the cars can avoid people using Liar. They avoid dynamic path planning and they have no need for traffic laws which explains the 2017 to market time.

I am skeptical on university campuses adopting this. Get on a bike people. Golf courses and retirements homes, well those may have use cases.
if you are climbing and you weight your equipment even for just a second, the whole ascent does not count

What do you mean by that? I read it as if using a scale to know the weigh of your equipment makes the ascent not count.

If this is correct, why would that be so? and if not, then what did you mean by that?

Also, why is style considered so important? I mean, is there a similar requirement for diving for example? I know that sports with rules have...well, rules. But for something like climbing, why would that be something to take into account except if you are part of a league that certifies ascents in a particular way for example.

Could you expand a bit on that? it sounds quite interesting to me.
Hmmm, well, what metaphysical Right does the action of creating such a phone fall under, philosophically speaking?

Which broader Right is this specific activity a representation of?

What does the act of fabricating a secret keeper mean, and does a company gain rights, or are the rights of some set of individuals collectively conferred upon the company by default?

Would making a different object, such as a gun, alter said rights? Pretty sure the constitution says Apple can proceed without interference, but these are questions worth contemplating.
That's exactly what netbooks were, right? And Chromebooks are basically a resurrection of the same idea.

Tablets basically took that space, I think.
> It's not trivial to defeat strong encryption, but it is doable given sufficient interest.

That is as wrong as saying that, given enough effort, you can make 1 + 1 = 3. Cryptography deals with unimaginably large numbers, to the point that for some algorithms and keylengths an exhaustive bruteforce attack would require more energy than exists in the universe.
This is not "never trust the programmer", it's "do we hand the programmer a broken library?"

Hi there! That sounds bad. Could you let me know what's giving you the impression that that's Asana's goal?

We really try to explicitly avoid that kind of interview evaluation, and put strong emphasis on Communication, User empathy, and Learning, per the guide. But definitely "did they say the right answer?" is an easy trap to fall into so its entirely possible that some interviewers are doing it -- would love any concrete feedback you could give to help us avoid it in the future.
SNES Super Mario World Turned into Flappy Bird, by Code Injection
I have a place in my heart for concatenative languages. When I was a junior engineer in 1970 working on the first sealed hard disk, I used forth to build test routines for the disk. I started with transferring bytes, to seeking, up to reading any block. It went fast and was very flexible.
A Statistical Analysis of Reddit Gold
The EFF's Andrew Crocker suggests that the "Vulnerabilities Equities Process" (the result of a previous EFF lawsuit) might legally require them to reveal how it was done: https://www.eff.org/deeplinks/2016/03/fbi-breaks-iphone-and-...

Regardless of the legal requirement, others (and likely Crocker) don't think that this is that likely to happen, though.
The question isn't whether we moralize about the dangers they face in a profession they choose from options available to them. It's whether they're paid equitably for the job or are exploited for the benefit of western companies which neither provide adequately for their families in the event of their death nor enforce safeguards to limit their risk to the extent possible.
> I appreciate the sentiment behind documents like this, but, Asana, you can do better. When you do, you'll find it gets easier to hire people, and, perhaps counterintuitively, the quality of your hires will go up.

I agree! (I don't even think it's counter-intuitive at all.) Thanks so much for really clear feedback.

> It's an interesting piece of history that not a lot of people realize.

I think it's pretty commonly known the Byzantine empire was Christian and did rule in many of the lands you referenced.

> all Christian before the armies of Islam came in 632-1683.

But to call these countries (to the extent they're even comparable geographical areas) as 'all Christian' is nonsense. For example, Berbers in Morocco in 500 weren't 'all Christian', not even close. Some surely were, and they'd surely been influenced by it like many religions before, but they weren't all Christian anywhere to the same extent they're virtually all Muslim today.

> That's why all these places have/had Christian communities. They're the leftover conquered people who were too stubborn to convert of leave under the abuse of their Muslim rulers. It's not like a bunch of Christians have ever immigrated into any Muslim country - lol!

Again, take Morocco. A lot of the Christian communities that exist today aren't remnants of settlements that are 1500 years old. Take Volubilis, a place where once Christians lived in Morocco, it's been abandoned for almost 1.000 years. Rather, many of today's Christian communities are remnants of much more recent migration, a few hundred years ago, in a colonial context. e.g. about 100 years ago a quarter million Spaniards lived in Morocco, most of them Christian, and - lol! - they did migrate to a Muslim country. Countless other examples exist, millions of Christians migrated to muslim countries during the colonial era, and indeed they also left their mark, and not all of them left.
If it is indeed the FOV that makes the difference, this implies a potential solution for when a game needs to move the camera independently of your body: limit the FOV as the camera moves.
Not saying this is good contract writing, but some relevant context would be what the penalty for breaking these clauses are. If the penalty for not maintaining compatability, as stipulated in the contract, is simply "we turn off IFTTT integration with your app", then that seems reasonable. Ditto for the non-assignment clause.

Now if the penalty is three dogs and a pony, then nuts to that.
We also don't elect presidents based on who people "tried to vote for." Bush won the first count, and he won the automated recount. It should never have progressed further than that. 7 of 9 justices agreed that the ad-hoc recount that applied different standards to different counties violated the equal protection clause.

Moreover, we have no way of knowing whether Bush or Gore "won" Florida. Voting is a mechanism for measuring something. Like any method of measurement, it has a margin of error. The margin between Bush and Gore was so close that it was almost certainly smaller than the error in the voting mechanism itself. The scientifically right answer would have been to exclude Florida (and, in fact, several other states decided by very small margins) from the sampling process.
> First, what polls say is not the same as what the electorate believes. Actual voters skew older and more conservative that the general public.

It seems to me that minority interests have a disproportional influence on policy decisions and that a single issue may not have a high enough priority to get elected representatives to change policy on that issue.

For example, if you look at the the NMSL (National Maximum Speed Limit) that was in effect from 1974 through 1995, it was quite obvious, based on traffic speed measurements, that almost no one was complying with the law on interstate highways, yet it took 13 years before it was modified to allow for 65 mph speed limits and another 8 years before it was repealed entirely.

So, it's entirely possible that the electorate was not in favor of that particular law long before 1995, but that single issue wasn't important enough for congress to vote on for around a decade.
I know it's not worth anything, but I used to work with an ex-NSA cryptographer (whom I personally knew in meatspace and yes, actually had worked at the NSA) who claimed that they could create purpose-built machines to factor out keys and read the contents of encrypted messages. The target would have to be high-value as this was a costly exercise. He may have been yanking our chain, but for what it's worth, that's what he would claim. He didn't specify which individual ciphers this applied to.

However, there are so many ways to circumvent encryption that it seems that there aren't a lot of cases where a hard decryption of a previously-coded message would really be required (the target can often be compelled or tricked into giving up his keys, a plaintext version may be intercepted at some point, etc.).
I agree with the bulk thrust of this. The classic writeup on the OR/FB marriage is this http://assayviaessay.blogspot.com/2014/03/virtual-spaces-rea...

> Citizens United came from the Supreme Court, an institution that is explicitly designed to be shielded from the will of the people as much as possible.

The people have nothing to do with that decision. It is just plain unconstitutional. The framers of the constitution never meant for personal rights to be applied to corporations.
For the record, it was not Oracle that was "doing squat". Oracles's JDK keeps improving, and btw Oracle is paying for most of it. Since Android "fork", Oracle added generics and lambdas and G1 and bazillion other improvements.

The company that was "doing squat" was Google. Their shitty (and incompatible) Java implementation is where Oracle's was 6 years ago.
Virtual Spaces, Real Data, Why Oculus and Facebook Are Bad (2014)
I find eating and drinking, while difficult, to be far more satisfying when i'm in virtual reality.

It is, in a way, a coordination of 3 identities: the virtual me sitting in a theater, the physical me clumsily making a mess of his face, and the internal ego sitting back judging both of them. It's a pretty easy way to get an out-of-body experience.

Also: if you can manage to replace your friends with cats, I find they are much more proactive about interacting with me when i'm in VR.
Apparently a 3rd party from Israel (http://www.cellebrite.com/ [unconfirmed]) helped the FBI which begs the question, how did they do it? Do they have universal access to all iOS devices or just this particular device?

If there is a known vulnerability, I'm willing to bet Apple will find it rather quickly. I'd imagine Apple has engineers pouring over the source code now.

> I would wager there are many boxers out there who disagree.

A boxer would say YDKSAB.
I'm sorry to hear that story. I hope this doesn't come off cruel because it isn't meant to be, but there are always outliers -- people for whom the gold standard, or any standard, just doesn't work. It's not a good idea to dismiss a well-studied treatment universally shown to be effective because we don't know if it'll work in a specific case. It's important not to anchor a patient -- already living on the edge -- with thoughts that 'maybe this isn't going to work for me'. On average, most people are average.

What we do know is that CBT is exceptionally good at handling most cases. No single treatment (for any disorder) works equally well/at all for all patients, but of course medicine is concerned with helping the largest population efficiently.

I hope one day we understand the brain better, to the point that people like your relative don't have to suffer anymore.
Thanks! I will need to figure out how to configure mgetty to do an ATDT6 on dial.
Most likely it's already been fixed.

The iPhone 5C in question uses an A6 processor. It encrypts data by comingling the passcode with the unique device ID to create a a strong 256-bit key, so you can't just pull and brute force the flash memory chip. Meanwhile the OS will wipe the key if you guess a wrong passcode too many times, making the data forever inaccessible.

However there is one vulnerability with the A6 that some have theorized.[1] If you could somehow get around the wiping part, you could keep guessing passcodes. A typical 4 or 6 digit passcode could be guessed in under a day. So it may be possible to copy the flash memory into a soldered-in test rig that is effectively wipe-proof. It would restore the contents every time it's wiped. So that's the best guess I know of for what happened here.

But starting with the A7 Apple added the secure enclave. This now enforces at the hardware level an escalating time delay with each wrong passcode guess. It goes all the way up to a one hour delay.[2] That's also where the (unreadable) unique device ID resides, so there's no swapping out the processor with a rig. The key is forever wedded to this protection against brute forcing.

That is pretty darn spiffy from a security standpoint. If it works as designed, about the only hope anyone has of getting at data from an A7 or later device is through iCloud backups.[3]

[2] https://www.apple.com/business/docs/iOS_Security_Guide.pdf

[3] Either that or some kind of peek into the secure enclave. It's specifically designed to inhibit this at a hardware level, but perhaps a nation-state could figure it out (e.g. verrrrry carefully grinding it down without destroying it and looking at state with an electron microscope).
Did it at least support Ethernet by this point

Luckily, yes. It had an Ethernet port and TCP/IP, so once it was up and running, getting it on the 'net wasn't too bad. The biggest challenge was actually getting the IT dept. to assign us an IP address, etc. Luckily I knew the IT guy pretty well from doing work-study with him earlier, so it wasn't too bad.

On the other hand, while you could telnet to the thing, you couldn't really use plain old command line telnet, which usually assumes something like a VT100 or VT200 terminal. AS/400's usually want 5250 terminal emulation, not VT100/220. So I had to find a 5250 terminal emulator to use to connect to the system and actually work with it.
I have to admit I use IFTTT to take an RSS feed from our kid's elementary school and post the entries to a Facebook Fan Page. The idea being to avoid having to teach my wife to use an RSS reader, now she (and another hundred or so people) get the school news without leaving Facebook.

I feel conflicted in some ways but pragmatism wins. Anyone know a non-IFTTT way to set this up?
Indeed. It blows my mind sometimes how much people, including people who really ought to know better, grasp at the ideal of having the One True Explanation and One True Treatment for depression. It's not even just the division between biological and psychosocial approaches; I've seen some very troubling, almost childish bickering among adherents of various psychotherapeutic schools (some of the more esoteric and old-school types denounce CBT in much the same terms that they denounce drugs), and have learned the hard way that if I ever hear my psychiatrist tell me that something is "a really good drug", I need a new psychiatrist.
What is your source on that?
[Urgent] Don't read this
That's an interesting point that I haven't heard mentioned. What if the FBI got to the data not from the phone, but iCloud. That honestly actually seems easier.
