>Holders of large amounts of bitcoin are often known as whales. And they’re becoming a worry for investors. They can send prices plummeting by selling even a portion of their holdings.

Written another way: People who would be financially penalized greatly for selling might sell!

The media and public believe that a group of people who want nothing to do with fiat currency might all of a sudden decide that they were wrong all this time and take massive positions in fiat currencies. Why? My only guess is that the media believe people buy Bitcoin just to ride the wave up when what's actually happening is people are exiting the fiat system. This is why Bitcoin's price curve is similar to trading pairs associated with hyper inflation. A Venezuelan who holds dollars isn't going to suddenly want to take a huge long position on the Bolivar. At minimum they'd exchange the only minimum amount to transact with someone who doesn't except the dollar (or Bitcoin) yet.
After starting with Dale Carnegie’s book I’d move to something more about the storytelling aspects so you can construct your pitches well in addition to interacting well.

I don’t have a “great” book to recommend there, but an example that pops to mind might be Say it in six[0]. This sort of book tends to be more formulaic, less universal, and every book advocates a completely different formula so you need to find the approach and style that works for you. That said, understanding that a pitch is a structured story and thinking about how to structure them is incredibly valuable.

Simon Sinek’s Ted talk[1] is also really fun and well worth watching (and worth deconstructing how he makes his pitch about how to make pitches), but it’s more about high level consumer brand design than the inside the company project pitching like I think you’re asking about.

SQL vs. noSQL – the right solution
SQL bitches because of this situation; imagine that 2 users were accessing the database and while one was reading a list of id's in one table and joining them to a list of names with corresponding id's in another table another user was modifying the list of corresponding names to id's in the other table.

so nosql tries to solve this by basically using only the locks of update and read per "table" or "collection" call (meaning they have no JOINS and they have plenty of hard drive space) they do this by storing the "oh I need to look up the _id to get that name" directly in the first table or collection. nosql basically says let's fragment everything up into tiny databases and handle the locks at a higher level, like at the API between 2 or more parties so that 50 people aren't accessing something at once anyway. you have to admit that does seem prone to error

the issue is that then if you have a table with a million rows storing the same data there's no point in using the relational part of a database

what I do not understand, is why can't they just pass along a function allowing the user to lock and unlock their own database? Then the user just needs find, update and delete and if they wan't to join in any crazy way they can dream up, they just do it in the data loops (they can store it locally in a big loop while locking)

that is why db.lock() and db.unlock() exist in sdb, you only need to use them if this type of situation were to arise

Ask HN: Should interview challenges be paid?
I am in a situation where I would like to change workplaces but I get a tons of home challenges (homeworks) which could take up to 10 hours to finish. This is obviously taking away time form my freetime and job hence the question: should companies pay for the solution for challenges or not?
Why don't you leave then? There are jobs everywhere.

Even in the smallest town in middle on nowhere (say Montana) you can find a job. It might not be a perfect fit for your skills, but you can find one. There are thousands of small towns scattered across the US with some little company that makes something obscure but essential to society. Example: you probably never think about sewage pumps (not the treatment plant, just the pumps by the side of the road) - they are essential to society though and somebody needs to write the software that controls them. Why not you?

Of course moving implys a lot of changes. You can't go to a Broadway show (you live in California so you can't anyway - which is why I use this example), the community musical in the next town it pretty good though and the fact that they are not on the level of Broadway makes them fun in a different way. Or maybe you can find a different activity to fill your life with once you limit yourself to 9-5 plus the 15 minute walk each way to the other side of town to get home.

Of course there is nothing wrong with Montreal that the other poster mentioned. It is a nice city if you decide that a city life is for you. Of course it is in Canada which might be a negative for you, but you can still choose from any of several hundred cities scattered around the country. Nothing wrong with any of them either. All have specific advantages and disadvantages.
Please see my reply to mywittyname, basically, there are certain situations where being able to take advantage of our globally distributed infrastructure is the best call and I 100% agree that there are situations where using a local db is simply the best (only) call.
I've felt the same way about "slow as hell left lane campers" for years and thought that maybe — if states never did anything to fix it — there might be a commercial solution to fixing this.

The idea I came up with awhile ago was to build a network of motorcyclists willing to attach a sign to the back of their bike, that reads (something like), "You're causing traffic by being in this lane at your speed - please move to right as soon as it's safe to do so." The motorcyclists would make their way in front of the slow left-laner - so that the sign is visible to the slow poke - with the hopes of persuading them to move to the right lane.

Meanwhile, also on the sign would be instructions for the other drivers out there, who witness the value the motorcyclist provided, to send a little micropayment electronically to the motorcyclist as a thank you.

Maybe this takes the form of a grassroots DIY movement where the motorcyclists handle all this themselves, or maybe there's an opportunity for a company to exist that creates the signs and facilitates the micropayments - and in return takes a cut of each micropayment (a la Patreon).

Obviously this assumes that all this can be achieved safely and legally. Thorough testing would have to be done on that front.

Let me know if anyone wants to kick around this idea further - even if just for fun.
It depends. If you're very new and can stand the typos... maybe.

But, I would say price/quality is not that great. The whole bundle should probably be about ~20$ IMHO.
Nobody is "lucky" to be working long hours. No matter how much they love what they're doing.

An engineer making $150k working 60 hour weeks is making $5/hr less than an engineer earning $100k working 36 hour weeks. The latter is literally earning more _for their time_ working half as much for 2/3 the salary.

The hourly rate of an engineer earning $250k for 60 hour weeks is the same as an engineer earning $150k for 36 hour weeks.

The difference of 14 hours a week is 30 1/3 days/year. Some folks are willing to trade an extra month of their time per year from the prime years of their life for money, but not me. It should be a choice, not an expectation.

Maybe your perspective is different because you're a founder, but I get the feeling I wouldn't want to work for your company.
Just because driving is a privilege, doesn't mean that it is ok for the government to use broken systems that do not accurately catch lawbreakers.
Most managers fail in the "knowledge of basic stats" and "access to decent tools" areas. And if they have the knowledge, most larger organizations don't have a ton of managers sitting around writing python code during the day. Their day is full of meetings.
I was in a huge lecture hall and the presentation from the head of school was going to talk. He plugged in, turned to look at the display from the projector and it hadn’t come up yet. He types in his username and password and stood there waiting. When the projector came to life he had typed it all into the username field.
He fixed it up then displayed his desktop to us with all the pending final exam papers sitting there. No one in the hall showed any obvious sign of realising what had just occurred.
Seems like it is getting harder and harder to promote original content on the web without being considered spam.
I think product-hunt might be a useful tool in promoting something like this but I do not know if it is the right place either...
Go ahead and make a five page resume, but:

A) Make it dead simple to visually distinguish between jobs/entries.

B) Put your most important things in the first two lines, because that's all I'm reading until I decide you're worth investing time.

Also, do me a favor and collect all your keywords in one spot so I can skim them. Don't make me read line items to even figure out which technologies you've worked with.

Anyone with more than five years of experience who still does a one page resume either has done absolutely nothing useful or is cheating themselves.
Well, in this case it looks like they have decent built in webpack support.
Same problems as you, but I disagree on the touchbar. It’s one of the better things Apple has added recently.

But holy hell do they need to work on their external monitor support. Yesterday I had one of my monitors randomly go black for a second. I’ve had audio over usbc just not show up anymore and it refusing to see my gigabit ethernet when waking up unless I unplug the actual ethernet cable. Simply amazing this passed their QA - and Id find it hard to believe no one at Apple uses clamshell mode with two monitors.
MSI's Aero lineup looks quite good, very similar to the Quadro cards.There are some simple white lights on the logo, although those can be disabled if they bother you.

Thats why at any given speed, there is a maximum capacity of any road that when surpassed causes traffic, i.e. people speeding up and slowing down due to differences in each other's acceleration. This is unavoidable and the only solutions involve increasing everyone's speed, reducing # of vehicles, or making the road bigger.
I can only comment regarding Django and it mostly boils down to python vs Ruby and what is idiomatic to them
Like the idea, but the cost is too high. I would think that having no physical location helps reduce the cost. I'll continue to go a mile down the street where the person will do it for $15 per notarization and I can haggle; I usually get a 20% discount.
I'd hazard to guess that most people complaining about price are misguided gamers who think Nvidia is now charging them 5x more for a card.
Great resume in general. However, you don't list a single quantifiable achievement in your work experience. You state what you did, but in no way provide data to describe the impact of what you did. If you'd include that, your resume would be outstanding.
Looks advanced for my 22 month old. Still, I like to keep him challenged. If he learns anything now it will be a bonus.
One of my first jobs out of college was software sales. Really opened my eyes to the absurdity of that industry.

Very wolf of wallstreeet-esque. The tech was mostly repackaged opensource software with a nicer UI and the senior sales guys were doing copious drugs and bringing down like six figure commissions on multi-million dollar contracts. They hired an army of associates to generate leads and then swooped in to grab the commission. The play was to cold call the shit of company, weasel you way into a decision maker's schedule, and basically roll the dice they might buy your software because they needed to check a box - it barely mattered what the thing actually did and beyond a well rehearsed script no one understood even the basics of the technology/problem space. It was also very feast or famine - a few made absurd cash but most lived on a precarious edge where they felt they might be fired at any moment.

Understanding this is how the world actually works was a valuable education. I do feel with the rise of 'big tech' things have improved a bit and there is a renewed interest in approaching business problems with data and something that approximates a pseudo objective science-like process. But barely.
An interesting comment given that Apple as closer to infinity resources than anyone else.
There's a case to be made for public shaming, sometimes. You're leaving it up to Apple to decide whether they want to pay you or not; they might deny the bounty for some reason, while still fixing the bug. Now you get nothing, in addition to having given Apple time to sweep the issue under the carpet and bury it under a change-log with language that heavily downplays the severity (e.g. "CVE -
A buffer overflow could cause an application window behind the lockscreen to retain focus".

Posting it on Twitter, however, draws attention to Apple's waning security practices and how such glaring holes manage to slip past their peer review. It sparks public outrage, and may serve as a wake-up call to the company.

So you're going to start typing terminal commands into peoples locked macbooks on the offchance that they've hit this bug and are running a terminal?

Its a flaw that needs to be fixed, for sure, but lets not over-exaggerate the severity as an attack surface. Its much, much more likely that it will cause accidental problems when the owner types something (like in the tweet).

> if this bug is real

Why wouldn't it be? Plenty of people here and on twitter are reporting having hit similar issues (with OS X and even linux, so it doesn't seem completely uncommon).
Have you tried Apache Spark + pyspark + Jupyter? Spark allows SQL against all data frames bound to the current context:

df1.createOrReplaceTempView("table1")
df2.createOrReplaceTempView("table2")
spark.sql("SELECT * FROM table1 t1, table2 t2 WHERE t1.id=t2.fid")
I use a 12.9" iPad Pro, because in landscape with 2 pages side by side, it's feels just about the same size as reading a physical book.
It's precisely the same as Maxmind for me -- about 50 miles off. GeoLiteCity.dat.gz is about 11 megabytes, i.e. one penny on a cell connection. I'm not sure how this makes sense as a business, since the value in a geolocation database lies in having cars constantly driving around sniffing people's IPs.
How long has this been the case? Was it ever thus?
My X 2015 had significant performance issues and Bluetooth would randomly stop working. They didn't upgrade from Marshmallow 6.0.0 to Nougat (7.0.0, not even 7.1) until last month.

I bought an iPhone X. I love Android but most manufacturers don't seem to care about the product after you've purchased it.
If the voting body has the option to vote people into office who will overhaul the state government or vote in amendments to that effect, the illegal actions of the state is 100% the citizens' responsibility. Everyone in the state who is able to vote should be collectively punished severely to give them an incentive to vote to change their government.
I found "Writing an Interpreter in Go" to be a much better read. It was actually completely portable to C++ and Rust, and that made it useful to pretty much anyone.

Data science and machine learning are different beasts. CS based Machine learning and AI seem useful in task automation. Its real value is in building IP.

DATA science is more like quant consulting.It is actually a subdiscipline in management science in my opinion.

The key role of a data scientist in non SV company is usually 6-fold.
First understand the business problem thoroughly. Get the people,process and value stack nailed.

Second and this is the most imp part. Figure out how to frame the business problem. Framing isnt as linear as it looks. But it helps save a ton of time and money if you front load time in framing problem. Substep here is to frame it as an "information" or data problem.

Third articulate a strategy to gather data or information. Inhouse data available? Web scrape data, buy data, build generative models. Youd be suprised how much ML work happens in this step

Fourth shape the information to a format that can be analysed.

Fifth, study the hell out of this dataset- the PHD angle comes here. Very few people are systematically trained to study data with rigor and be humble and honest about their findings.

Lastly connect the dots between insights and business problem at hand.too often this stops with bar graphs and some scatter plots. Thats just lazy. You need to really take ownership of the problem and educate business why the solution will help and be honest about ehat it will take to get it to work. The people, process,value stack in line 1 kicks in here in recommendation and action.

A bonus point. Put some kpi to track how well your suggestions are working.

Real data science is super super hard. Its like finding a real nugget of diamond in dust.

Data science is a way thinking. Its a business culture to be honest.
And some were gifted it. I remember a handful of sites that would give you some BTC just for asking as a demonstration of the technology. It was worth roughly a cent or two at the time -- obviously much more now if held.
Definitely done that before. Sent my password through Messages to a friend. After that, I learned to keep the finder or a web browser as the thing in focus before I lock my computer.
Does it matter if his points are valid?

I don't need to be a chef to know when the meat is spoiled.
I think you're mixing up the argument of whether property is just with whether property is coercive.

The arguments you've outlined are drawing a distinction between which kinds of property are thought to be just by certain schools of thought. However, this is entirely unrelated to the fact that all forms of property are coercive -- enforcing them ultimately requires (the threat of) violence.

Most people fail to make this distinction unless they properly think it through, though I personally find it most grating with the type of libertarian who argues with the "non-aggression principle" or variants thereof. I believe people make this mistake because it can be uncomfortable to admit to yourself that you're in favor of something that is coercive, even when the coercive thing is clearly a good thing overall. I'm sure there's a fancy name for this type of fallacy :)
FYI my first impression: The cover makes it seem like programming is bad (the black cloud above)
"I just realized that taxes are actually a form of forced altruism. The money goes towards good things"

Like war (on drugs, iraq, afghanistan), NSA, CIA, etc?
And you have also not much choice, if you don't support the spending on the current education system for example.

Thats why it is not a donation. So in my Utopian future taxes would be indeed voluntarily and directly bound - so if there is no money for certain things, then apparently nobody wants them. I suppose most people favor education and streets over sustaining a global invading force, but I might be wrong. Anyway, still a long way to go for this ...

In my experience there have been problems for a while with sleep/wake if you have external monitors. I'm running 10.12 (work computer, no option for 10.13 yet), and I have three monitors connected to my MBP. I had to adopt a ritual about disconnecting the first screen, then lifting the lid a bit to activate the internal display, then disconnect the other two monitors, then close the lid. Otherwise more often than not when I woke my computer up next it would not have a usable desktop -- the dock would be on a nonexistent screen and could not be found. I got pretty used to using spotlight to load terminal and blind type 'sudo reboot'.
Added to my cart as well!

So rape and pillaging it is then.
+1. I'm finding this book really useful for getting my head around machine learning and TensorFlow.

Also Deep Learning: A Practitioner's Approach by Patterson and Gibson.
If you're writing your first page as a standalone thing though that matches what the posting is looking for, do you think you need to eliminate unrelated things on the remaining pages?
It's funny, I'm the exact opposite of you. I vastly prefer one pagers and find most longer to be unnecessarily verbose.

A sister poster listed a set of bullets they like to see; accomplishments, engagements, projects (I would call this all "telling your story"). I'm of the belief that for most people, you can well and truly fit this on one page. I've gotten patents, spoken at conferences, published papers, worked from tiny contracting firms to tech behemoths, and can tersely summarize the important bits for a given interview in a page.

(I mention this to shake my head at awj's somewhat tone-deaf assertion that someone with >5 years experience and a one pager has accomplished nothing)

When I'm interviewing others I find that there's often a gap between "diminishing returns of what I can get out of a denser resume" and "the meat of really getting to know how you'll perform as an employee", and that the most difficult part for me is less filtering the former and more getting to the heart of the latter when it is at its core an extremely subjective question that one has to explore differently with each candidate.

My overall thesis re short resumes has some obvious caveats: I tailor my resume for the job in question and certainly don't enumerate all, outdated, or irrelevant accomplishments. I also don't tend to include any sort of "personal statement" or longer form in this enumeration; I'd typically consider that a cover letter if one is even applicable.

As an entertaining cap to how differently we seem to approach this, I've even been turning over the idea of condensing my resume onto a business card, and think it's situationaly very possible.
No, it clearly states that it is by Kickstarter in the copy.
Do you prefer "2006–2009" or "2006 – 2009"?
You can't compare Rails to Express. It's a much, much more full-featured web framework. JS doesn't really have an equivalent to Rails (that I know of).

Django is comparable in scope but Rails is many times more popular and a lot more work has gone into it. IMO you would need a very good, specific reason to choose Django over the far more popular Rails.
It's not too difficult. a) only the application with keyboard focus gets to open new windows with keyboard focus less than about two seconds after a keystroke (with no intervening mouse activity). b) no keyboard input into a new window for the first second, unless the user clicks there.

We looked into this while I was Trolltech. Decided against doing it for Qt unilaterally, it's really something the system must do, or else it's too annoying.
