The bufferbloat guy is much better at explaining this than I am. The problem needs a PR guy, and now it has one. I wrote this up in 1985 as RFC 970, "On packet switches with infinite storage", which is about why giant FIFO queues are bad and you need fair queuing at a bandwidth choke point. People who read RFCs and IEEE Trans. on Communications know about it. But I've been out of networking since 1986. (A non-networking startup wanted me to Do Something. I did. It worked out well. I never went back to networking.) So nobody was pushing this.

Fair queuing seems to have been an idea that was used for a while and then forgotten. It's been an obscure option on Cisco medium-speed routers for years, but only on by default for 2mb/s links and below.[1] Most of the attention on congestion control went into the TCP side, not the router side. There was too much attention to packet dropping, rather than packet reordering. In a router, you can do three things about congestion - drop, reorder, and delay. For decades, most of the action revolved around dropping, with Random Early Drop being popular. Reordering means you get to make decisions about what to reorder. That leads to policy issues, traffic shaping, quality of service, administrative interfaces, tuning knobs, and customer service/help desk calls. Which is why QoS never went much of anywhere outside of some tightly managed networks.

A big contribution of the bufferbloat guy is that he promotes the original dumb fair queuing - each source IP/source port/destination IP/destination port is one flow, and you service each flow equally. Nice and simple. No tuning. If that was in the middle of the network, you'd worry about people getting more bandwidth by gaming port numbers or something. But what's the point of gaming your own personal DSL router? In practice, the things that need really good latency on home DSL uplinks are acks, voice over IP, and game user action traffic, all of which are low-bandwidth. So the simple approach is good enough.

Early routers had barely enough CPU time to copy the bytes, let alone do fair queuing. So it wasn't in early routers. It's also a bit complex for a FPGA, so it's not in the big ones which route in hardware. (Nor is it that helpful there, because backbone routers don't buffer much.) That's how we got here.

It's embarrassing that this is still necessary to talk about. There's no excuse for big DSL operators deploying millions of routers with giant dumb FIFO buffers. Come on, AT&T.

A fair queuing add-on box is a definitive win only if the next link has a fixed data rate. DSL yes, cable maybe, cellular probably not. Cable modems at DOCSIS 3.1 and above are supposed to have DOCSIS-PIE [2], which is supposed to fix this.

Now will someone please do a startup that builds a little box? As a hobbyist thing this goes nowhere. As a little box you buy at WalMart, it does.

Or, AT&T guys, get your act together and ship this as standard. Thank you.

i wonder whether some of those vendors (may be some one who already has hands deep in that city IT pockets) gave the tip to the reporter and thus it is a "submarine" of an article to force the police department to upgrade and to provide PR cover for it.
"Candidates will submit their project ideas. Each week, the projects will be updated. The candidates will vote on each other’s projects, points will be awarded and there will be leader board."

I like the stated mission, but this approach concerns me. Silicon Valley has ingrained in our shared consciousness the idea that genius or potential for societal contribution == creativity == (usually) a business or project. Having a thing you want to make and then problem-solving a way to get there. There's nothing wrong with that approach, but it's one of many, and for an organization that's claiming to seek out all flavors of human potential, it's extremely limiting.

Many - possibly most - of the world's greatest thinkers didn't have a "project", or at least that wasn't their primary activity. They didn't follow the model of

1. Have an idea

2. Execute on it

They lived, experienced, researched, contemplated, discussed, expressed. The literal "Einsteins" - the rockstar intellectuals who made it all the way into the popular consciousness - might have had a single big creation that made them famous. But they didn't set out from the beginning with that vision, and they make up a minority of the world's successful geniuses.
How could "but it was just a generic racial slur aimed at a whole nation!" make this any better? The correct line of defense would be "Musk said something stupid, move on".
I just use a dark chrome theme with it to get around that issue.
Who is paying to support you while you explore some curiosity of yours? A PhD program is not a summer camp, it's a social tool and the public is paying money in order to grow the human knowledge base. I don't get this attitude, appreciate the fact that the public is giving you grants and funding because the alternative is you get nothing.
Basically every human endeavor "should" be about putting the general good over the individual good. After all, it's in one's own selfish interests for that to be the state of affairs; there are far more people not-you doing things than people who are you doing things, so you stand to benefit more if all those not-you people are doing work that indirectly improves your quality-of-life. ;)

The (sometimes literally) million-dollar question is: how do you align incentives to bring about that desired end-state? Ph.D's are not unique in struggling with this age-old conundrum; if the government is willing to pay for robotics research for drone warfare but nobody is putting up the cash to pay for nursing-care robot research, then we can make some pretty firm predictions what kind of robots we'll see mature and reliable in twenty years.
It just spins forever for me.
My experience was the opposite. The people in my PhD program (at an upper-tier state institution) were far better thinkers in my field (biology) than the people in my major at an upper-tier liberal arts college (who, granted, were largely pre-med).
Well, in three years when the headline is "Baltimore police pay $240M for failed Lotus Notes migration," then I'll click. But sometimes maintaining the legacy system is the lesser of evils, especially in government systems.

We built a custom management system for a state agency here 10 years ago. The state still pays us around $40k/year in associated improvements, changes based on new legislation, reports, etc. Far less than paying $1M-$2M to rebuild the thing, or more. Total cost of ownership for the system is ridiculously low, all things considered. And yeah, it's written on some old crufty PHP, but it still does the job and they use it every day.
It’s not your audience; it’s Facebook’s audience. You’ve just been granted the temporary privilege of access to them with no further guarantees.
Same here. I've always had some mild OCD but last year my car got stolen and that's when it really started. Before going to sleep I now have to know where exactly the car keys are, even though I'm both better insured and the lack of keys didn't really stop the thief last time.

What's worse is that while I've also always been a chronic key checker, last month I still managed to lose the keys. On top of that I didn't even lock myself out - either they're somewhere in the apartment(I'm at a loss here because I went as far as going through the trash - to no avail) or the single time my OCD didn't make me check if whether I left them in the lock I did just that and somebody took them.
I've always thought this argument was really hypocritical. The argument is you shouldn't be concerned about a few percent of equity since once it matters you will be rich and not care. Except the person making that argument is certainly rich and seems to care a lot about these few percentage points. Why are we expected to not care when they clearly do?

Similarly, those few % of equity means less equity later for future rounds of funding or for paying out to employees.
Then you need to show that any un-initialized byte can either never be read or is of a fully mapped type where it doesn't matter.
That sounds horrible, but I'm not sure that explains the numbers. A quick internet search suggests that LGBT youth have 3x the suicide attempt rate.

https://www.thetrevorproject.org/resources/preventing-suicid...

Given that LGBT is maybe 4-10% of the population of the population, it's not likely to be driving such a big spike in the total numbers. I'd be interested in a more careful breakdown if anyone has it.

Additionally, my interactions with Mormons suggests them (and pretty much everyone else) becoming more tolerant of LGBT, not less. However, that's anecdotes, not data.
Disciplined Minds is a great read.

Early on the book discusses some data that indicates more highly educated people tend to be more supportive politically of the government than the population in general. (E.g. during the Vietnam war lawyers defending anti-war activists in the US were trying to figure out how to pack juries with people who would be favorable to their clients and discovered that roughly the more educated someone was, the more likely they supported the government and would disapprove of anti war activism)

The book makes the argument that gaining professional credentials is less about gaining knowledge/skills, but more about demonstrating that one can be trusted to work in an organisational and confirm to the assigned goals/ideology of that organisation.

One rough argument made in the book is for workers performing roles with work that can be completely specified by superiors, it's less necessary for workers to demonstrate they can conform to how their employer wants them to think, provided they do the work. For professional roles involving more intellectual work where an employee's day to day tasks cannot be completely specified in advance, it's important for such employees to demonstrate they can think how the organisation wishes them to think, so an important part of training for these roles is essentially political training.
I would argue that Trump is an opportunist. For evidence: see his extensive dealings with the Clintons and Democrats in the 90s and early 2000s.
Silicon Valley corporations that are doing this are run by foreign nationals. I'm not surprised they don't support our military. If you're Sundar Pichai or Satya Nadella, who do you want to win? USA or India? Google won't help with Project Maven, and Microsoft won't support ICE.

In contrast, American Jeff Bezos hasn't backed down to pressure from ACLU about supporting law enforcement with facial recognition and his newspaper here is pointing out the problem of foreign nationals attempting to cripple our military readiness.

I realize this won't be a popular view here, but it's fairly obvious to the layperson. Some of our premier companies have been infiltrated at the very highest levels of command and are being turned against us.
>Most people still think having OCD means you’re a neat freak or like your shoes precisely lined up in the closet. Come to my apartment; I’ll show you that’s not true. OCD is not a personality or preference. It’s a mental illness that can have devastating effects on how you live and interact with the world.

Well, yes, but it can also manifest in being a "neat freak" (and not just of the mild kind).

Have you explored offering pick-up directly from the commissary kitchens? Not sure what local regulations you'd be navigating there or provisions on your lease, but redirecting diners there with some collateral you include with every delivery order could provide you additional orders without paying the platforms for every order.
I have been reading more and more about CBT. I will research about it and if things swing the right direction I'm going to try it.

Thanks, man!
Ah, I see - though I don't think the distinction being social as opposed to linguistic makes a difference here. The question "what would you recommend doing about it?" would seem to apply both to how to classify Chicagoese, and how to stem its decline.
Uh, what do you think a downpayment is? It's proof you can provide the money promised/you are responsible with money...
I sympathize with your view, but I think the time pressure is a very valid thing to be using.

If we view higher education as being more about learning how to learn, rather than simply mastering a set of facts, we have to have limited time resources to measure how effectively a student learns.

In life, business, etc. we are almost always under time pressure. These tasks often include learning something - new facts, new concepts, new context. People who can make better decisions, produce higher quality results, etc. in limited time are precious. The time element of study time/test time is effective at measuring that.
The original article on bloomberg:

Has a seemingly less enthusiatic title:

Quantum Computers Today Aren’t Very Useful. That Could Change
I posted this article because we’re planning to do the same and wanted to gather thoughts from the tech community (the financial community has commented on this sufficiently to help inform our process).

I thought it might help to share our motivations for eventually listing our company vs taking more VC:

a. The public markets force transparency. This aligns with our values.

b. Governance enforced by VCs (especially in the UK) is largely founder-unfriendly. There are no prefs, investor majority consents or other unfair terms in company governance when you’re public.

c. Secondaries - shares sold by employees or early investors - can be sold at any time, at fair market value.

d. Capital raising - debt or equity - as a public company comes with fewer strings.

e. Friends and family and supporters can participate - especially from their retirement accounts. This is really important - the wealth creation being broad has a real good-news feel. Sharing the wealth.

f. Trust is built with the public - I feel - more when you’re publicly listed and ‘established’.

The ‘downsides’ of quarterly market updates I’m sure are more intense than it feels from the outside, but I’d like to think our growth story happening in a public sphere will help build trust so when we do need more capital a broader base of investors feel confident engaging with us.

Thoughts welcomed.
It's funny that I'm reading this thread because I just went through this exact same thing last night and it was weird. I don't ever make a habit of using my phone in the dark, but I did yesterday and I did at full brightness and for many hours and it did not feel good.

Eventually after like 6 hours in the dark and accidentally using just one eye for reading- eventually I started to see really trippy and weird visual noise in the dark areas of the room. I also noticed that if shone at the right angle- the pitch black areas of the room suddenly lit up, as though I was giving my over-exposed eye some kind of night vision, which is weird because you'd expect an oversaturated eye to be completely blind in the darkness.

Now this is all anecdotal, but reading screens in pitch black light has always felt bad for me. I don't understand people who insist on watching TV shows or movies in a fully pitch black room. I mean I get why school teachers and home theater enthusiasts do it- but for normal TV viewing, it just seems wrong to me.
Yes there's upward pressure on pay (and the cost of everything that pay buys) from the DC area but the DMV is no SilleyValley in terms of pay and costs.
What do you mean in regards to textbooks? Online rentals, digital textbooks, or something else?

Based upon what? The download is served via HTTPS, and offers a checksum also secured via HTTPS. Are we entertaining security models in which PKC is considered "not secure"?

Or are we just going by the author's ignorant or disingenuous (depending on how you interpret his words) statements?
Put your money where your mouth is. Buy at $350 currently which is a steal since this thing is going to $420, right?? LUL
Yes, also if your eyes are closed when it starts, 500nm is better because more gets through the eyelid. Better if you diffuse more and spread out the light over more of the visual field.

But the main thing you'll want to make sure is that you can get enough light. There is some evidence that >200 lux with this wavelength will help, but most light therapy uses tons of light (1500 melanopic lux or more):

1. I did not mean to imply that east Asian culture is inferior. I did mean to imply that it is much less emotionally comprehensive. I agree with you that the concept of duty is sensible and functional on the human race wide scale, and I was asserting that it cannot be a stand-in for all emotional fulfillment in an individual unless the society surrounding the individual also subscribes to that idea.

2. It is certain that there are many, many causes of the global immigration related tensions that we're experiencing now. I did not mean to imply that I think all are required to both understand and accept all perspectives, but rather that having such a personal goal holds plenty of progressive merit given that you think that the vector of progress lies along the direction of increased togetherness. There are merits to other points of view as well. I also urge you not to overestimate yourself, even though I personally have plenty of faith that you are personally very intelligent, and to question the emotion when you begin to feel that you understand another point of view. In my experience you oftentimes actually do not, and that feeling that you do is your brain employing the numerous heuristics its evolved to contain in order to fulfill the incredible task of synthesizing sense out of the chaotic and unfathomable complexity of all things.

Perhaps it's better to say that it would be good to endeavor to develop a perspective that is comprehensively inclusive of all other perspectives that one has encountered and can possibly foresee encountering. So rather than having a quiver of many arrows, there is merit to having a single arrow capable of hitting any target.

Well the point is, your brain does not control breathing in that sense, the medulla, nervous system does.
The article here has a lot of information that the one you linked to does not. I understand the fatigue, but this is no dupe.
I think that is extremely unlikely. If you were to have a scale of the volatility of security where a zero is potentially being entirely on your own and a ten is a very modest utopia where everyone can perpetually live like a student then functioning universal basic income is probably an eight. Much of Europe today would be around a five, with the Nordic countries maybe a six. The US, being unique in many regards when it comes to developed countries, would today overall be a something like a three. Without even the most basic assistance it is probably a two. You don't just go from a two to an eight overnight. It is just so far from what exists today that it is a pretty safe bet that a functioning universal basic income system is never going to happen in the US.
I personally don't distrust Signal.

I just refuse to use it. This comes up on HN a lot and everytime I have to admit that I am kinda unfair here: Signal is heralded as the nice and secure solution - but seems incomplete to me. I don't doubt all the more clever persons that tell me that Signal is the best choice for encryption right now. But as long as it doesn't support federation (I miss XMPP) and as long as it does require a phone number (None of anyone's business, not required for my contacts, a baaaad way to handle identification) it is utterly broken for me.

I'll continue to use Telegram for family, friends and casual business stuff. The applications are awesome across platforms, I can initiate conversations with people without using a phone number. Worse encryption? Probably. Likely. Just as centralized? Yes - hate it there as well.

But I hoped that Signal would be the solution. I'm unfair. Signal gets judged for NOT being open (federation, phone number). Telegram is just a random service that I use instead then - works better anyway.

Try blocking sdad.guru. I checked and it's one I've blocked myself, and Google says they're an adblocker-circumvention service.
It's not the end of the world, but I was subconsciously expecting 1080p or thereabouts. I agree, that resolution in 2018, especially for a 5.7" panel feels low. I had both the Nexus 5 and 5x that were 1080p.
I don't think so, ALL automated posting is blocked now ;(
Nice!

For the Slack bots, a fairly common thing we want to do is regular business updates from either Google spreadsheets (that are very dynamic/scripted) or from ChartIO. Some basic interactivity with those bots would be handy.
>Unless you pull a logical trick to reduce every discomfort to fear

In OCD there's no external discomfort (like having your hand touch a stove or having a headache).

So it can very well be all about fear and anxiety in general without having to "reduce every discomfort to fear".
Ask HN: Which obscure/young programming language has a lot of potential?
A Guide to Python's Magic Methods (2012)
Escalating benchmarks that add increasing optimizations to continuously one up one another. In the "logical conclusion" of this left unchecked, the Fibonacci benchmark for example (d)evolves into a lookup table.
Which is missing the original point, hence the desire to just leave everything un-optimized.
PS: I am so obsessed with it that i measured it 4 or 5 more times.

Did you even read the article? They knew enough to disable SOS and interior car alarm sensors in a seemingly subtle way most people would dismiss. Maybe they should’ve taken their time and waited around for police?

What’s unsophisticated is stealing a radio or nav by slashing the back of the wiring loom, and then the owner having to replace the entire loom at the cost of many thousands of dollars. It sucks but that’s life. Car thieves aren’t your friends, DGAF about damage, and those that don’t operate on a “speed is life” principle get caught. Maybe you should show a little respect to the knowledge and tactics demonstrated?
IMHO as a bi-racial person who has spent over a decade on three separate continents, I have come to a very different perspective on culturally-driven explanations for mores and behaviours like Amae, and appeals to duty /conformism/emotional repression. I don't beleive they are anything more than rationalizations for ingrained society-wide behavioral dysfunction.

IMHO, that is.
If you're worried about employees unloading shares and tanking the price, then hold off for a few days and buy the stock at a discount.

Historical use of a lockup isn't a reason to continue doing them.
You don’t just control a company for fun. I mean, maybe you do and more power to you, but just about everyone else votes in those elections so that the company will be better run, so that in the short/medium/long-run dividends or share price will go up.
>So, we’ve curated some of these golden games and will be adding them to Discord Nitro.

They need to focus this curation in a big way. There's been a lot of flack directed at steam for allowing it to be essentially polluted by all sorts of low quality "games" recently, and discord could really hurt them by actually caring about their community. Valve's hands off nature has not been easy on gamers
