> WeWork, WagLabs, and most VC investments contribute absolutely nothing of value to the world. If they didn't exist, no one would even notice their absence.

The irony of posting this on Hacker News...

Snark aside, to a first approximation, voluntary monetary transactions happen when one party gives another party something of value. If you move money around and end up with more than you started, that's because you moved money around in ways that provided real value to people. Now obviously this is an incredibly crude approximation, but the onus of proof is firmly on you to prove that VCs aren't providing value to the world. And please don't go the "I only said most investments contribute nothing of value" route, unless you also have a way to only pick startups that'll actually provide value (hint: if you knew how to do this, you'd be richer than Masayoshi Son).
The title of this post is very misleading. Verizon has made no change to the schedule of the shutdown other than allowing more time for end-users to request a partial download of data that they've posted. These downloads are incomplete and do not contain much of the metadata required to be useful for archiving.

Verizon are giving a tiny, meaningless concession to change the narrative and make everything seem fine now, but it is not. A vast trove of important historical information will become inaccessible and essentially lost forever in less than four days.

Verizon provides no way for anyone to download a complete, archival quality copy of groups. The only method currently available is by using the third party software that Verizon is attempting to block and this method will become completely unavailable after the 14th.

When I accept a physical note, do bits move on the Ethereum blockchain? If not, how do I know that it's really mine?

This reminds me of when people sold Bitcoin private keys ("paper wallets") on eBay. I've heard some people do OTC trades by swapping private keys when they don't want the transaction recorded, but I assume these people know each other well. You save money on miner fees and gain some privacy, but you sacrifice trustlessness.
One of the monitors leverages FANOTIFY in Linux to determine what files your application is using. This is the same thing many AV tools use to detect malware :-)

The future version will get more different runtime monitors and it will do much more with static analysis too. Right now its static analysis is limited to LDD-like dynamic library inspection for extra artifacts you want to keep in your image. There's a lot more that can be done there...

Intel’s SGX coughs up crypto keys when scientists tweak CPU voltage
I think the concept of decentralization is certainly appealing especially when it comes to trusting 1 or more other parties with personal information. I think encrypting data with only the parties you want to have access is extremely powerful. I might be wrong but as I understand it there is always an amount of trust whether it be in a blockchain or a single party. I understand that if the one party is compromised or decides to change their policies and sell your data etc. that it is a larger risk in that regard. On the other hand adopting a decentralized network takes a good amount of understanding and participation that might be lost on the average user. My hope is that, with a solid foundation, it would be possible to establish the initial policies to maintain and grow a network that was never owned by anyone e.g. https://en.wikipedia.org/wiki/Wikipedia:Ownership_of_content

For a moment I assumed that this was another of those cases where copy-pasting to HN lowered a subscript.

Anything similar in LA?
Assuming that the systems are truly encrypted end-to-end, how do we know for sure that noone can actually decrypt it? I mean, apart from the Eng team that directly works on that part, are we basically trusting them at face value that it works? Or does this code need to live in an open-sourced environment so as to make it more trustworthy?

To be clear, I don't mean trusting the encryption algorithm, that part is easy because math. I mean trusting that that algorithm is actually what's being used under the hood and actually noone can decrypt it for any reason.
Subreddit R/Unpopularopinion: Against the Spiral of Silence
Mate, you got got.
I think this article went a little too far and overstated the point.

I wouldn't be worried about charging my electric car in the city where I live. That's a nonissue, just charge at home.

I'd be worried about going longer distances. You roll up to the supercharger in the middle of nowhere, no ability to go anywhere else since you're out of battery, and every charging slot is full. There's a line of tesla's to get a spot. Sitting around in your car for a half hour as you wait for owners to leave to even start charging. This would be a legitimate fear of mine.
The reason for 2. is mostly a fear that such a person might not be very effective at communicating, convincing and listening to others. There is certainly also an element of social charisma to it. I don’t think it is something that can’t be learned though; in fact I imagine most people that become managers perhaps take the time to do just that.... almost like a self fulfilling prophecy.

Nobody is born a manager.
I’d guess the vast majority of web developers never use WebGL or Canvas directly. The alpha compositing we are talking about here is one of those, not the native compositing, because you wouldn’t use native compositing for image editing.

I hate crypto currency and I love this. It's a way to project all the insanely bad parts of crypto (if you hold it you own it) into the physical world. If general btc/eth transactions are a very very complex version of SWIFT this is the same for paper money. I can buy coke with my bitcoins but I can't do a cool in person coke buy with bitcoins(and/or ETH). Kong solves my problem.
There's a few going on. None are Facebook, they're unique in their own way.

WT.social seems to take a lot from its wiki roots, such as editing other people's posts. They make money just from donations.

Cocoon goes more personal. It's not about having a thousand friends. They're more a subscription model and can't exploit users.

I'm working at one too. It's something community based. You don't post to your own wall. You post to communities - a residential area, geographic location. We've had gaming groups and schools onboard; it's easier and cheaper to reach out than with Facebook and less intrusive than WhatsApp. It started off fairly serious but we're seeing more Instagram style selfies and Tik Tok videos. We monetize by selling community based services like condominium management.

This is just off the top of my head in 2019. There's probably some stealth mode ones going up in the near future. I wouldn't ve surprised if we see 50 more alternatives by 2025.

I think the important thing is not to make something ad based (which incentivizes addictiveness and privacy violations) and not to focus too much on network effects (which incentivizes monopolistic behaviour).
Why don't they use isolated laptops with only 4G access or dedicated external line?
The point is physical cash is really important to a functioning society.

Cryptocurrencies are turning out to be really important but lack a physical cash instrument.

Kong marries the two.

Kong accomplishes that by minimizing trust down to the chip level - as opposed to the firmware or application level - so we can make these things trustlessly and cost effectively. Something like a Trezor is too expensive and dear to be treated like physical cash.

It's a valid remark on how companies do tend to treat their workers as little more than livestock. While it is denunciatory, the subject deserves denunciation.
Same here, it was just a lonely conversation with people that only care about their idea. There was no real feedback and almost none listening to the complaints. It was a total waste of time because some of the only interesting lessons were removed arbitrarily.
My apartment building has a charger in the parking lot. Is it that weird to imagine that eventually chargers will become common?
> AFAIU, the entire security benefit here is due to ASLR alone. If an exploit manages to track down libc, it can go right ahead and make all the system calls it wants

It has to create the appropriate gadgets to generate function call sequences, and generating gadgets is hard.
Wow. A PhD, actively teaching, and this dribbles out.

Such is the wharrgarbl of the far left. I bet this paper is very popular among the more woke SJWs.
FYI, you don't need any special permissions to strace in a docker container - you just need to disable the default seccomp profile (docker run --security-opt seccomp=unconfined), which blocks use of many unusual-in-production syscalls including ptrace: https://docs.docker.com/engine/security/seccomp/

One common workaround floating around the internets is to use --cap-add SYS_PTRACE. This has the side effect of permitting the ptrace syscall, but it also gives you the ability to ptrace processes owned by other users etc. That's more than you need and it's kind of dangerous in a production-ish container.
All important caveats, for the lazy:

- SGX is disabled by default, it has to be enabled for this exploit to be relevant

- POC requires privileged execution, at which point you can safely assume all is already lost

A side note: anyone who has spent time around digital logic circuits will know that messing with voltages will cause errors. If the power lines are too low some transistors will not be able to switch their load. Or too high and you will cause parasitic losses or capacitance in unexpected places. This is actually a really nice attack to show off to people with an interest in computer/electrical engineering because it demonstrates how a basic design constraint can cascade in unexpected ways.
It is a particularly strong scam in the crypto space. I'm very impressed with the innovation in their area.

This is either some of the best satire in the world or I still don't get it. Probably the latter.
Good point. I would love to know why it's not a solvable issue. Not saying it's easy and I'm sure there's multiple reasons, some maybe unsolvable.

Because you're competing with Boston money. The fact that it's possible to live in Worcester and work in Boston (and the fact that Worcester is known for being nicer than New Bedford/Fall River and Fitchburg/Leominster) means there's tons of working professionals who are jacking up prices.

If they where making millions, then this guy sold himself cheap at 5K. He was literally the decision maker between them and millions of dollars. That is why they jumped at the retainer price. He could have hit them for 50k and they would not have blinked.
I can still see some value to building codes and regulations, but I really don't see what benefit the very strict zoning regulations are bringing to the table.

If my neighbor and I decide to sell our land to a developer so they can build a small apartment complex we should be allowed to. If the neighbors don't like the idea of having an apartment nearby they can see if they can get in on the deal too (probably turning a tidy profit on their lot) or they can suck it. It's my land I should be able to sell it to whomever I want or build whatever I want provided the structure doesn't pose a physical risk to my neighbor or their property.
Yeah, this sounds like something people would say in 2008, but not 2018. Facebook has lost a lot of favor since then.

Ask HN: What's your experience with online payment processors?
Hi HN, I'm about to launch a product that will require setting up online payments. In the past I have used Payflwow[1] from PayPal, with mixed results [2]. I was wondering what's your experience with payment processors and which one do you recommend!

PS I don't need to set up a POS, I just need to process online payments.

PPS I prefer products where the funds are transferred directly to my nominated bank account, as it's the case with Payflow.

PPPS I am based in Australia.

[1] https://www.paypal.com/au/webapps/mpp/payflow-payment-gateway

[2] I liked it because the funds are transferred directly to your bank account, but we suffered from a relatively high number of void/duplicated transactions, failures when calling the "Silent POST" URL, etc.
>Or is there an economist that can rationalize how the correlation between urbanization and urban problems can be positive while the causation is negative?

Sure, almost any if them can. It's called spurious correlation.

So if 100 people want to buy homes in the area and there are 100 homes available for sale, you think that building 100 more homes will actually increase the average home price?

More homes always means downward pricing pressure. That may not overcome upward pricing pressure due to other factors. But you can be pretty sure that housing in your area would be even more expensive were it not for the additional housing inventory.

The reason you have never seen cheaper housing due to new developments is because you usually see new housing built as a response to increasing demand and prices.

ie, fraud shouldn't be protected with the corporate veil.

What if this wasn't an isolated incident and only one that got caught? What if the person who took the bribes was part of a ring?

Corporations have a strong incentive to NOT root that out as it has negative image.
Usually I would agree with you but this is an intriguing concept. They explicitly state in the white paper that this is an experiment, so treat it as such. All I’m hearing is a lot of “contempt prior to investigation”.
Thanks for the feedback. That sounds like a bug. If you see the two quotes and didn't see the tabs you definitely weren't playing anything. Specifically it sounds like we failed to load the song data, so you don't really see anything at all.

This is typically a momentary issue. If you want to give it another try you can go back to the track or song selection page and try again. That generally clears the problem up.

(The problem is that data file wasn't fully flushed to disk when the player tried to open it. If you give it a second and try again it generally works.)

If the file happens to be very large or the network connection is slow you might see this more often. Also if you are a little more leisurely about going from the track-selection page to the player this is less likely to happen.

Worst case scenario is that the data file was somehow corrupted when being written to the cache. That will clear itself out eventually, or you could clear the cache from the settings panel, or try another song if you are just playing around.

I know this seems like a problem that should be easy to fix, but it's been a little bit of a whack-a-mole problem to address all the edge cases. I'm sorry you ran into this, but fortunately it's almost always a temporary glitch.
Good point. "Leaving now^W some years later". And midweek Lucky Star can now be $15. I don't know what gray market is - perhaps still $5-ish?

So a narrower gap than there used to be. For labor mobility, perhaps a difference that still matters for commuting on minimum wage. Exploring a possible job. Geographically broadening one's social support network.
Extraordinary Folkloric NPCs
That seems accurate. The advent of the 'personal computer' allowed many to get away from the (often necessary) restrictions (including expenses) imposed by the use of mainframes. The result was freedom to program and experiment with hardware and software. Proprietary systems (Windows, Mac) once again built in restrictions and limitations for various reasons.

Linux doesn't. Its many distros are the response to widely different usage needs, ranging the gamut from turnkey to roll-your-own (Arch, Linux-from-Scratch). If you don't like some feature of a program, you can modify and re-compile the source code.

The software repositories contain programs offering a few to dozens of different ways for users to accomplish their goals. Many users are drawn to understand the details of computing, and to experience the power that confers, as opposed to simply operating an appliance.

In short, many Linux users are the same sort of people who made 'personal computing' possible in the first place.
You can see this playing out in real time as politicians are inviting companies like Facebook to be involved in coming up with regulations.

You should use experts when coming up with regulations. But you need to use unbiased experts. Anything that Facebook suggests will of course amount to nothing more than a moat for their existing business.
See the thing is you didn't do the work, they did. If you can't get anyone to make the tech yourself then that's just how it is. If they decide to make the tech and it is worth 250 million then pay up, or live without it, or try to make an equivalent in house. You don't own your team, you will do whatever is in your best interest and so will they.
>Business are criticized for not providing full time positions with benefits.

That may be a factor but at the low margin "we just need you to have a pulse" end businesses mostly don't care what you think about their benefits package.

The problem is in the law. It is very hard to just hire someone off a street corner and comply with labor and tax law. Then there's civil liability. Employers mostly can't afford the risk of just hiring whoever shows up because god knows who they are. If they decide to shoot up half way through the workday and get hurt or hurt someone the employer is gonna wind up footing the bill. Unless you have an army of lawyers who have figured out how to insulate you (e.g. the gig economy) it just isn't worth it to take the risk on someone you can't vet.
Not really. One realization is that doing and seeking gradual excellence can be a better teacher than reading (or other forms of un/intentional procrastination). If you happen to learn from someone else's mistakes, that's great. Make lots of survivable mistakes while try to get the fundamentals right... which means you're doing and learning. Learning is the most valuable.

Attitude and schlepping that translate into sales and delivering sh%t cures all. There's lots of annoying and mundane stuff to do, and some things you'll always forget, but it all adds up and you'll get better over time (especially by keeping searchable notes; I have a terrible memory).

Of the books by actual billionaires who have BTDTBTTS , I'd read Felix Dennis' ironically-named How to Get Rich for fun. It contains more of a meta autobiographical attitude insight through stories instead of cargo-cult practices, business theater or phony shortcuts. Supposedly, he claims he was Sir Richard Branson's roommate at one point. Too bad he passed from too hard a life from too much hookers and coke.
From the whitepaper: "Kong notes do not use a secure element that allows for general programmability." Looks like they thought this through more than a typical drive-by 'blockchain' project. With a limited secure circuit you'll be able to call functions that generate ECDSA key pairs on the card but without exposing an interface to retrieve the private key. Without this basic property you would have to fully trust that the issuer had not mass-extracted private keys (similar to how early privacy coins had a trusted setup phase.)

Looks like they're also trying to structure this as 'reward cost for key extraction vs cost of mounting attacks' showing they have a plan in place for attacks. I'd argue the notes still have a tx cost though because the only way to know if a note has a valid private key is to challenge it with a unique, large, random number - which takes time and effort. Users of the notes will need an app for that and have to check every note against an on-chain 'smart contract' before accepting them? NFC might make some of that easier but there are still usability issues there.
