Professionals are often wrong, and timing the market is more difficult than it might seem - in no small part because many investors are unable to prevent emotions from affecting their trading decisions.

That said, it's entirely possible that the market is irrationally high; the question then becomes how long it can remain that way. There's a famous Keynes quote - “The market can stay irrational a lot longer than you can stay solvent.”

If you do think stocks are overpriced, it may be advisable to create a disciplined strategy for profit taking - selling a few percent of your net assets each time the market increases by, say, 10%.
I mean, what does "improving urban transportation" actually mean?
I’m sure the positive anecdotes and trends are accounted for in the data, but nevertheless the data still says what it says. Uber and Lyft aren’t here to solve for transit access and commute optimization, they’re here to serve as many rides as possible.
>"While we should explain more clearly that these services are used to protect consumers from fraud."

So if my someone's phone is lost or stolen they won't be able to use their credit card or debit card? Wow that sounds like quite a service - losing access to your phone now means losing access to your money? So your card is blocked because of a fraud alert and you have no ability to call your bank or credit card company. You better hope you are not by yourself when this happens.

I would close or cancel any account or card if they ever put me in such an imposition as a result of using this service.

The cost savings are not the main advantage of AWS Lambda compared to EC2 (AWS recently announced EC2 will bill on a per second basis and a minimum of 1 minute). Instead, I'd argue that the programming interface, managed operations, and scalability are what makes it a better tool for these types of tasks! I'm looking into running other more general computations on Lambda right now as part of my PhD! (stay tuned for more soon). Until then, check out ExCamera (https://www.usenix.org/conference/nsdi17/technical-sessions/...) and PyWren (https://github.com/pywren/pywren).

It depends on what you consider as market in which Uber/Lyft operate. If it's entire personal transportation market, then one can think of them as in a zero-sum game with other players. I believe that the ride share market (even if you include taxis) is a growing market. Sure, it is very competitive so there is some struggle to gain market share, but there is also incentive to grow so as to get that economies of scale because whoever has that can price extremely competitively and be the winner.
I was told guix has some support for importing normal Nix packages, but I don't know how well it works in practice.

A large portion of those voters are paranoid about the government taking their stuff and keeping lists.

Yet if it's privatized it's ok.
No.

You were actually initially right, I searched for that actual part and it is indeed a bimetallic strip along with a heater (that turns off when the strip moves away from a contact) and not a device with a solenoid/relay.

Apparently whatever it supplies is tolerant of that sort of interruptions in its power source -- I imagine that it would operate on a quite lower frequency than a "vibrator"-type power supply where magnetic force moves the contacts (and elasticity returns them).

Nice, I'd never heard of this technique before to create 'smoother' bokeh.

Although I have seen some examples of people cutting a shape in card and placing in front of the lens, to create different shaped bokeh, like hearts etc.
Curious: has anyone tried linking a Postgres installation with a MySQL installation using https://github.com/EnterpriseDB/mysql_fdw ?

My intuition is that, if there's anything MySQL does uniquely well on the "being an ACID datastore" front, then this would let you get the best of both worlds—essentially letting some of your Postgres tables use MySQL's storage engines et al.

If you do that, every access will actually dereference that pointer and won't be able to optimize the standard style indexing to a multiplication and addition, so this still carries a significant performance cost.
Discoverability is a problem everywhere in Nix, from configuration options to documentation. Which makes it necessary to learn its weird poorly implemented functional programming language and read code. Then there is performance, it's very slow and uses a lot of memory making it impossible to use on a 512 MB vm, for example.

If you just want a solution for your packaging management needs - Nix is definitely not it. Nix is more like a thing to get inspired by to make a package manager.
Which other "Anglosphere" countries promote home ownership the same way that the US does with e.g. mortgage interest deductions? There are many pairs of otherwise culturally similar countries with differing policies on this (e.g. US & Canada, Belgium & the Netherlands).
In many smaller towns, and even larger cities where taxies are not common, this isn't an option. When I lived in Mesa years ago I'd call cab services multiple times and they'd just never show up. Many smaller towns just don't have taxi services.
Would you be willing to provide some guidance on how you achieved your positive change? I am sort of in the same place right now, and progress from conventional therapies have, as you said, "hit a wall". I couldn't find any contact information for you in your profile, but I would appreciate any info you could provide.
The understated importance of embracing our irrational side
Around a decade ago, chickens were infected (I don't remember with what) and were making people sick in Cairo. So most people slaughtered them and threw them in the nile.

The nile is also the source of Bilharziasis. The nile is where a vast number of people throw their trash.
Would love a Brompton. I ride a Dahon (less so with Lyft) for the commute and Cannondale on the weekends. Once we move to a larger flat I'm going to gift myself a folding electric bike.
Nice. I started using macOS 5 months ago and it felt a bit as a step back coming from Linux.

Does Nix work good with macOS?
You can sequester the carbon in a product and still be able to use it without releasing it to the atmosphere.

For example you can sequester the CO2 in limestone which is a useful building material.
Even internally to Amazon, it's misunderstood.

The point is to gather all the facts, make a decision as a team or group, then have everyone commit to the decision and not whine about how they should have done what I said we should do. You disagree, but you commit to the decision of the group for cohesion and productivity.

It's also a means to prevent groupthink. No one should be thought poorly of for disagreeing, so everyone should be giving all their thoughts, even ones that contradict what the group is thinking. Just so long as they get those points out before the decision is made, of course.
That chart seems to directly contradict the oft-repeated advice of “never try to time the market”.
Ask HN: Gerrit-style commenting platform for Volatility output?
Volatility is a powerful way to detect traces of new, sophisticated exploits that are not yet detectable by antivirus programs. It would be great if there were a centralized place where people could collaborate on identifying such exploits by submitting output from the many volatility plugins.
I'm gonna need a better reason to switch distros than that. I do think that is an improvement that needs to be adopted in the OS. But, I mean, it's not that much of a improvement over containers. I don't feel like it gives me, the user, that much more power over the OS and would be a feature that I would only use very rarely.
It's also to speed things up. Many drivers want to hit their timetable; having to give change to 3 or 4 different people per stop is going to kill that.
Please define "free".
One of the major turn-offs for me in regards to Nix was that it uses a ton of bash scripts.

Guix's use of Scheme is a lot more elegant and powerful, and a lot less hacky than bash.
Why Amazon Would Want to Buy Slack
I really think the biggest roadblock is the command line interface[1]. To replace Homebrew you only need like 3 or 4 commands. Right now, that means 3 or 4 different nix commands with weird arguments. The way Nix is currently set up is great and make sense for the OS, but Homebrew has a much simpler use-case (single-user, all user land packages, very low barrier to entry). I can't wait until that ticket is addressed.

Yep, that's what the legal language says.

It's obviously not workable, though; you can see that the goal listed before "privacy" which all Californians have the legal right to obtain is "happiness". This would appear to imply that you have the same legal rights against someone who violates your privacy as against someone who makes you unhappy.

Reliable as in being able to get one. If you park somewhere out near Hanger Lane say, an uber is a few minutes away from your side street, a black cab is unlikely to be there for some days.
I think once people are used to getting around by opening a smartphone and putting in a destination, there's a lot of potential for offering transport-as-a-service more efficiently than a private car the whole way. I've already seen Uber appearing in Google Maps directions, and with a bit more work you could combine that to offer Taxi -> Train -> Taxi for the full journey.

Indeed, I think there are a lot of benefits once these systems start being integrated. It would likely facilitate ride grouping, since you'll have a lot of people arriving or departing from the same place at the same time. Combined ticketing could also allow stations to have special entrances for taxis that bypass ticket barriers, since they know everyone inside has already paid.
At a guess, China. Natural resources (including agricultural products -- not so "natural", I guess) are what China is getting in return for its carefully selective but large and wide-spread investment.

Googling a bit:

This article doesn't clarify who the investors are, but it does also/further describe the situation:

https://www.theguardian.com/world/2015/apr/14/ethiopia-villa...

I find it more than a bit... "ironic", that "Western" concerns are pushing "communes" -- which sound more than a bit like "communism", but appear to have a different construction, here; people aren't left on the land but are told to form "communes", um... somewhere else. But, they are pushing this "commune-ism" to the same ultimate effect: Pursuing their own interests, while screwing the people affected.

Again, talk of a "Master Plan" but not of who and what, ultimately, is behind it.

Ethiopia has been pursuing a lot of tech to control and monitor media and Internet access. For some years, now. To my limited knowledge, they were one of the first/leaders in African states doing so.

I concur with what other commenters have mentioned- without clear licensing indications, this is sort of useless.
Chariot is doing a good job of bridging the gap between Lyft line and public buses. Providing an alternative to the overloaded, slow and unpleasant public transit in my area. They haven't added an on-demand offering, but I'd love to see it.
One option would be paying for a VPS on AWS or Linode or DigitalOcean or Vultr or any number of similar providers - pick the lowest spec machine, raw network throughput is not very hardware dependent - and set the VPN up yourself.

Streisand is pretty useful for this purpose.

Did you like the kit?
The problem is that your car-driving case presumes the driver already wants to go to MV and is bringing his friends and they don’t mind coordinating to make that happen.

If you change your thought-experiment to a paid service, good luck being cheaper than CalTrain.
My experience with Nix was a real pleasure, and a complete failure.

I set out with the goal of building a development environment for a software I was working on. I thought - Nix sounds like a better Docker, where it's possible to choose package versions independently of the rest of the system. It's perfect for testing!

I found the package description language refreshing - it was powerful without getting too complicated. Over the course of a couple of days I was able to adapt a few packages and create my own too, with the build environment.

It was almost finished, but the last problem remained: installing CUDA and the userspace portion of the Nvidia driver. It's not rocket science – I thought – all I need is a few .so's, it even works with Docker.

Alas, after battling Nix for another couple of days, trying to use generic GL, installing the Nvidia one, ignoring it altogether or trying to using the host version - I gave up. I found no way to build a package linked against OpenGL that would actually work.

Despite that, I hope to use Nix with a different project in the future.

The research (and ride-hailing firms themselves) suggest that ride-hailing can be complementary to public transit.

I'm a former PT taxi driver (suburban city next to large urban area) and a lot of our business was from or to mass transit stations and the airport. These services (car and mass transit) complemented each other, but I don't recall anyone criticizing them for taking riders away from buses or the subway. The main complaint was cab rides were too expensive and the medallion system was unfair.

One thing that was different then compared to the use of ride-sharing services now: Rarely did we have a pickup from a private home or random street address to another home, random street address, restaurant, or movie theater. However, this was before the smart phone era, so random street pickups were either flag-downs or via public phones.

I also used to live in London where private car services used to be very common before the rise of the smart phone or ride-sharing services. They were necessary, particularly in neighborhoods where it was hard to get black cabs or there were no tube stations nearby. The main complaints against the private car services came from the black cab industry.
Arthur Schopenhauer on the Dangers of Clickbait
Highway safety statistics have significant limitations with respect to fine grain detail and data collection capability. Any datasource that uses police data must account for jurisdictional differences in data collection as well.

Nothing is wrong with the statistics, it's how you use them. It's just difficult to meaningfully say that it's safer to take the bus from point A to point B using statistics that are generalized over time and geography.

For example, 30% of motor vehicle fatalities are alcohol related, and the vast majority of those fatalities take place after most people are done commuting for the day. Uber probably has a significant impact on preserving human life, after dark.

The purpose of the anecdote is to illustrate how those stats relate to decision making and risk/reward management by the travelling public. Am I at more risk driving three exits down the highway vs. crossing a busy avenue, sitting at a bus stop, riding a bus, crossing three other busy streets? I don't know -- and those statistics that you are citing don't answer that question. My guess is that I'm safer in my late-model car in a typical automobile accident than in any traffic or crime incident in the bus case.
There are quite a bit more complicated issues that require handling than just the erase count for each erase block. One part is that there are many things that the SSD controller does and keeps track of in order to increase the endurance to the maximum, things like:

1. How many bits of error did we detect in the read? Maybe it's time to relocate the data before it dies completely?

2. How long does the write takes? Maybe it is time to retire this block because it is near dead for unknown reasons?

3. How many times was this block read? Maybe it is time to relocate it before we risk read-disturb issues?

4. Try to distribute data evenly across the flash dies?

5. Ensure we have enough erased blocks to write into to avoid blocking new writes.

6. Can I do some background operation? I really need to garbage collect and rescue some nearly lost data.

What you suggest (and I entertained for a while too) is to return to the pre-IDE (RLL/MFM) days where the OS would do all the hard work and get all the flexibility. But the OS vendors do not want that complexity, with the more advanced technologies involved it is hard work and more importantly, it varies between vendors and for flash it can even need tuning for different flash generations or even batches. The OSes don't want that complexity.

On the other side, the different SSD vendors want to use the lowest flash chips and get maximum revenue. The algorithms that they implement are their trade secrets and the thing that makes them able to charge more for the better devices. If they were reduced to a flash dealer they would find themselves getting less money.

I do think that having a nearly raw flash interface and having a better processor above with possibly better algorithms would yield better results (especially if you integrate it deeper into the user application) but the complexity gets that much higher as well for the entire app and when (not if) there will be another technology the entire app will need to be rewritten which sucks.

The trick is to cut them down at the optimal point (some time before they stop growing) and replant. Then use the wood in a way which won't release the carbon back into the atmosphere: don't burn it or let it rot.
Funny as hell. Perl, though.
Well, it was not really meant entirely seriously, of course.

I can't speak for other devs contributing to the project, but I think the mailing list is a great way to do this. Ultimately, what you want is a simple way to track information about reported issues, discuss the details, make it reasonably simple to search for existing issues, and post patches fixing the issue. A mailing list does all of that, without having to deploy (and maintain and curate) a separate system.

Why do you think it's more difficult to report a bug this way, compared to a bug tracker? There's even a "report a bug" link on the project home page, where you can submit a bug report through a simple web form (you need a community account, but every other bug tracker I'm aware of requires that too).

Can you explain why you think a mailing list is less efficient than a bug tracker?
Recently, I got the opportunity to play with Nix. To me, it felt to be a very nice way to bundle the dependencies along with the application. But there are few questions which always come to my mind were - how people run it in production. Can they achieve all the things (eg monitoring, debugging..) easily just like the app hosted on a linux machine ?
Don't forget the parking. The TLC vehicles are taking over all of the public spots in NYC. There should be a law requiring them to be parked in a commercial lot.
I think that deserves consideration, along with the related category of access-impaired riders. In a major city it might easily be cheaper to pay for years of door to door service than make an ADA retrofit for a subway station in an old building.
Surely that same information about the time until the next bus is also on a website? The bus company has the data, so why wouldn't they put it online?

This info is online for (at least) Christchurch and Auckland buses in NZ.

Well, "i don't think he will enjoy himself there"... what's the goal? Is it to learn something or to have fun? ;) ;)

I would recommend stepping a little outside his/her comfort zone and learn something completely different or adjacent to the current skill-set. For example, if the primary end-user of his efforts is a VPC on HyperV, adjacent: go to a Microsoft virtualization conference; completely different: go to vmWorld.

Also consider locale and time of year. Vegas can be brutal in the summers, but the fall and spring are Goldilocks.

I don’t really understand the article cemenet manufacturing releases CO2 because the limestone (CaCO3) is calcinated and turned into lime (CaO) in the process of making cement.

The article says (2nd half the first half just describes a cemenet that isn’t made with limestone) that they capture the CO2 and make more limestone form it I’m guessing by sequestering it lime so in theory it can be carbon neutral (albeit I don’t know where they get the lime from without breaking limestone) but how does it become carbon negative?
That quote should be the metric by which code/languages are judged.
UBI does this already for raw flash devices: http://linux-mtd.infradead.org/doc/ubi.html
For me, the gold standard of these libraries is Apache POI and NPOI. Porting to Rust would be perfectly possible, but it would be _a lot_ of work. Until you support that level of functionality, it's pretty much irrelevant what your "performance" is. You can always improve performance by dropping features.
Could you explain what you mean by mortgage interest deductions? Does it mean that mortgage interest can be deducted from taxable income? Even if that income is unrelated to the property?

In the UK landlords are allowed to deduct mortgage interest from taxable rental income, but this is currently being phased out. (A good thing in my opinion)
