Meetup majorly pissed me off. I've never been back.

I was going to the monthly IoT meetup up to about 2 years ago. The current maintainer was moving across the US, and wanted to transfer the group (nonprofit) to me. Seemed simple enough.

We go through the steps and then I get hit with the gotcha: pay $15 a month! Uhhh, $15 a month for what amounts to a email list and a webpage? I don't think so. Perhaps I could export the list and use my own platform? Nope! But they do offer great suggestions, like charge dues.

In the end, I "let" the group die.

Thats axiomatically impossible. Its the amount of energy required, not nhashes/etc, that disincentivize an attacker from rewriting history.
The Best Car Stereos with Apple CarPlay and Android Auto
I strongly disagree that CPAN is the best package manager. The CPAN repository might be one of the largest for a specific language, but the cpan comnand line is aegul, you can't even remove a package automatically with it.
Don't get me wrong, because I love Perl, it was my main language for 10+ years, but the default package manger us awful.
I think the "Bitcoin billionaire" is more of mythical figure than real people.

To be a Bitcoin billionaire, even a multimillionaire you had not only buy thousands of Bitcoin early on, you had to also:

- Hold when it was valued at USD10 (it was a milestone that generated a lot of buzz that it was a peak value)

- Hold when it was valued at USD100 (it was a milestone that generated a lot of buzz that it was a peak value)

- Hold when it was valued at USD1000 (it was a milestone that generated a lot of buzz that it was a peak value)

- Not lost the password of a negleticble amount of money stored as virtual currency that no one quite understood in a virtual wallet you are not sure where to keep.

- Not be hacked in several ways, included in the biggest exchange of the early days

Is anyone guess how many people are left after all that. My guess is that I would count in one hand
Hashed Time-lock Contracts
Ok non-dom but it comes with some strings attached. I understand you must pay £30,000 per year and the proceeds of the sale of the btc must never be repatriated to the UK.
2 isn't true at all, routing isn't nearly that complicated and I don't know why everyone thinks it is. Most routes are expected to be under a few hops. But regardless we will find out soon as the number of nodes on the live system is very rapidly growing.

3 doesn't really apply, as channels can be used as middle hops to rebalance.

If I give money to you for a good/service and drain my channel. Then I buy more Bitcoin from coinbase, coinbase can route that BTC to me through you to rebalance our channel so it is all on my side.

4 isn't true, as "locking the BTC up" is basically making it available. Would you consider depositing cash into a checking account "locking it up"? Because that's the equivalent here. But also locktimes are normally a few days.
So... Wouldn't burning wood meet the headline?
These are all very good questions! I wasn't trying to pass judgement one way or the other, I just think it's an interesting discussion point. Certainly, if crypto currency is going to stay mainstream we (the US) will be regulating a lot of this in short order.
I was wondering recently, why Bitcoin is even needed for a Lightning-like network? Just settle the channels in cash (or even bank transfers), it won't be any more traceable than Bitcoin. Moreover, there is a successful precedent of such network: https://en.wikipedia.org/wiki/Hawala

Seems like a large enough "overlay network" over cache reserves and bank accounts can be made barely traceable and pretty efficient.

The comment about declining population looks really off. I think most of protected old town areas lost population compared to 100 years ago. People no longer cram in tiny rooms, undesirable ground level flats are converted to shops. Why would this ever be a problem? They have Mestre just over a bridge.
I think this is going to be one of the biggest challenges in the field of AI going forward. How do we make sure that as an extremely powerful tool, it gets used responsibly. Also, acknowledging that like all tools, AI will be misused or applied in some truly heinous ways (examples across the internet if you're interested), how should the AI field respond and learn from this? This article is certainly evidence of people pushing in the right direction, even if some of the answers are a little woolly.

Ultimately, I think that the best answer is for AI Devs themselves to be extremely clued up on the potential social impacts of what they are working on and treat that with the same reverence as staying up to date on the latest literature. Only then do the kinds of "specific impacts" which the article brings up become clear enough to act upon and plan around. From there, one can work on safeguards, due diligence, or whatever else you want to call "making sure my tool doesn't hurt people".

You need to bridge the gap as much as possible between engineers sat in a plush office in SV, and the individual who is going to have their life affected by those engineers (and their AI imbued tools). Otherwise, it's just too easy to loose touch with what you & your tools do to the world and the people in it.

Fee does not apply in the first 7 years. You could move to the UK for one tax year, and then move to Sweden, taking your money with you. You would have booked your entire gain tax free since it was "taxed" in the UK.

Or you could move to Malta for a tax year, and then move to the UK. It would be tax free as well. In my view worth doing if it's a sizeable sum.
Yeah, which is imperfect but there you are. It means sometimes out-of-order packets will be reordered, and sometimes dropped (since TCP acked it, the (existing) TCP code will discard the out-of-order packet as 'duplicate'. Which turns out works pretty well in practice, since out-of-order are almost always in a burst (no delay inter-packet)
> doesn't require your master private key

So it does require the private key to your hot-wallet to be on an always on, networked machine, right?

And the hotwallet and lightning channel can only transmit, across all channels, as much as is in this hot-wallet, and each channel has a potentially higher and rising transaction cost to open as lightning network will generate more transactions to the blockchain, not less. So you can keep your cake safe, or eat it, but not both.

I'll take the bitcoin cash approach, please. Worse is better.
The problem is that, effective in a few months, this argument is not considered sufficient. You don't get get automatic permission to use private data just because you "need" that for revenue. People have an unconditional right to their private data, your business does not have an unconditional right to revenue or success. You get only the data that users consent to. If that's not sufficient for your ads, revenue and service, then tough luck, adapt or cease operations; if your business model is not compatible with user privacy then that business model simply is not valid anymore.
Ask HN: What's your backup strategy in 2018
I have a number of different machines and devices: Android phone, multiple Macbooks, a Windows Desktop and a Linux NAS. I'm having trouble coming up with a comprehensive backup plan.

At the moment, I sync everything with Resilio (sync is another question). After that, I take time machine and Carbon Copy Cloner backups of my primary Macbooks to an external drive. I also run Back blaze on the Macbooks.

I'd love to have a more comprehensive plan in place so I'm interested to hear how everyone is handling backup?
Bitcoin is both a currency and a payment method. Everybody knew right from the beginning that it's not a great payment method. The 10 minutes delay is a long time if you want to prevent double-spending.

For fast payments nothing beats a server with credit accounts. Naysayers will say that it defeats the purpose of bitcoin, but nobody thought bitcoin would entirely make banks and their fractional reserves system disappear. If anything, people will still want to borrow money.

Banks could function on top of cryptocurrencies, the difference would be that their clients would be able to withdraw their funds out of the banking system alltogether at any time, that is not just turning one credit into an other.
That's honestly not a bad price for the service they render. It's not just about emailing people, they can recommend your group to users, host a whole discussion forum, etc. Shame that you can't export the contacts, but I really don't think that's an unreasonable fee.

I guess purely logically, you are right. But I would be against the underlying theme behind that general type of thinking. If you take that line of thought and extrapolate it, it starts getting close to a socialistic/anti-economic progress point of view.
Lightning will become centralized into services like banks and Paypal since it's too difficult to use for an average person, which completely defeats the idea of Bitcoin as P2P cryptocurrency.
Competition is designed to have roles succeed, not people. In business or sport, we want the best to succeed. In that sense competition is a success as long as it's fair. The people or businesses in the competition are essentially replaceable.
Except china had the one child policy which clearly had long term goals in mind. Singapore also implemented eugenics policies and still has them to some degree.

Realistically population one of the few things you can take a long term view on, since so geo politics and technology are so unpredictable. With population planning much of the effects are only to come a generation later so mostly only a long term concern. It is also completely radioactive as far as modern democracies are concerned.

Not really. DAG/lattice based cryptocurrencies offer different security guarantees compared to blockchain based ones.

(1) is false. If you're not online, counterparties might decide to close open channels. But that just means you get your share of the funds in that channel refunded to you. You would need to pay a transaction fee to the bitcoin network for the on-chain transaction, but the other party doesn't get any of your money.
The only taxes you owe, are the ones you legally owe. Saving on taxes also doesn't mean you can't give back.

On a trip to South Korea more than 10 years ago, I was in a "hip" clothing store with my wife's cousins. We found a shelf of hats that said "Mount Cabot Lodge" + my home town & state.

My home town has ~15000 people, is not really famous for anything and there's no "Mount Cabot Lodge". Mt Cabot is actually ~200mi away. I figure someone threw a dart at a map of the US and used that to pick the town. I regret not buying it.
In 1989 I worked at a pharmaceutical firm that still had a secretarial pool. As a lab technician if I was writing a document (typically a Standard Opening Procedure or SOP) I was expected to write it by hand and leave a copy in my outbox (literally one of two trays on my desk) with the correct request form. The next day I’d receive a draft, and then I’d painstakingly provide corrections (typically every technical term and chemical name was wrong) and repeat as needed, after about a week we’d be good and it could be signed off and filed. While this felt inefficient, and probably was, part of that process also included review from my boss, so done was reviewed and done.

When someone wanted to call a meeting, that was another form, then invitations in inboxes (again physical trays on desks) replies, room assigned. Meetings were scheduled at least a week out. The flip side is that you could and did request secretarial support for meetings — someone in the room whose only purpose is to take notes, and who will go back and type up detailed minutes.
And it wouldn't run at all if you had more than 1 CPU. I remember disabling one core in a Pentium D processor to keep running Windows 98.
>> Because who I'd be was just another ordinary, mediocre 12-year old girl. I rubbed at the calluses on my hands, sat in front of the TV and felt terrified that I'd never again be good at something. Nothing is scarier than that.

To some extent, this is common in th west. But why is this so important to not be ordinary ? Why isn't it good enough to be good at something at your friends group, family, etc ?
I wouldn't say trivial, even if you know how the system works, it can take a lot of time to break things. A good example would be Enigma. There is the BOINC based project Enigma@Home [1], which tries to decypher intercepted messages. Over 74880 CPU-years have been spent to crack messages, and there are still some unbroken.

And do not forget the Voynich manuscript [2], from the 15th century, which still remains un-decyphered.

> Though, I don't know if every Russian (for instance) would be able to enter a "English" password.

I believe in every country with non-Latin alphabet users have two keyboard layouts: local (e.g. Russian) and English/Latin. All major OSes (desktop, tablet or mobile) have install-time defaults like this, and I never ever saw any divergence from this rule, except for removing native layout if it's deemed unnecessary and going English-only, or configuring system to use some third language (e.g. a foreigner setting up a device purchased abroad, changing the defaults). I mean, I never saw anyone in their sane mind removing English layout and keeping only the local.

It is virtually impossible to use computers without having to type in some Latin characters on some occasions, like typing URLs or email addresses. Therefore, I think you may reasonable safely assume capability to enter basic Latin.

However, you should also consider that user may forget to switch the keyboard layout (happens all the time), so if you want to do some password transformations like case-insensitive password matching (due to Caps Lock), and you have significant foreign user base, you may also want to consider common keyboard layouts issues (e.g. "hunter2" <-> "ргтеук2" for QWERTY <-> Russian).
If that is a legitimate concern, then don't use Touch ID or Face ID. By using those a person is intentionally choosing convenience over security. By even saving passwords in an account-shared fashion (be it Keychain, LastPass, or 1Password), you're giving up some security for convenience.

The latest iOS versions have also included a "five clicks on the power button" emergency option, which disables both TouchID and FaceID. It's not perfect, but if you're going into a questionable situation, it's a good way to avoid being coerced into using those to unlock your phone.
What's your home address?
Backblaze is so overrated; I really don't understand why so many high profile computing people have endorsed it.

Last year they lost one of my drives — the whole backup of the entire drive 100+ GB and support just threw their hands up. Of course I only discovered that they lost it after the physical drive failed.

Still looking for a better replacement. Arq didn't quite do it for me.
> You would need to pay a transaction fee to the bitcoin network

So a micro-transaction is a 10 cent payment that can turn into a 20 dollar fee plus 10 cent payment?
Uncomputable decimals and measure theory: is it nonsense?
0-confirmation transactions were working excellent before Bitcoin Core added SegWit and other useless stuff. You don't need to wait for a new block if your signed transaction is in the mempool, and it's secure enough for small payments.
This is the difference between weather (tide) and climate (rising water levels).
I’m amazed there hasn’t been another startup trying to be a better meetup, especially now when there’s so much attention on loneliness and lack of social interaction.
>Bitcoin Cash seems to be doing just fine with on-chain scaling

Has it though? AFAIK it still has lower transaction volume than bitcoin.
Runahead execution – An effective alternative to large scale execution windows [pdf]
There are 382 papers if you include the "suggested" in the readings section of this course. Genuinely curious how many students actually read.
Interesting title but this is just an excuse for a long form autobiographical blogpost.
See section 9.5 of the lightning whitepaper:

> 9.5 Forgetting to Broadcast the Transaction in Time

> If one does not broadcast a transaction at the correct time, the counterparty
may steal funds.

You need to be online all the time (or at least frequently enough) so that you can publish a penalty transaction if your counter party tries to steal coins from you.
What I learned from it:

* You really need to add a C++ compiler to your configure.ac. I see some tricks coming up with clang++ compiling the llvm gluework to bitcode and shipping this, but I fear it will be too big. And then you need clang.

* ORC (lazy compilation is back) can finally do again what the legacy jit could do: native jit on demand with a stub, into modules and adding functions to modules on the fly.

But the new llvm stuff is exciting: saving the old headers as bitcode headers, merging and doing expensive inline optimizations with these in the background. Remember, the legacy jit was gone when it couldn't support cross-jitting to foreign architectures needed for lldb. OCR jit can now do what MCJIT did, cross-arch jitting, and it got lazy compilation back. The module abstraction with it's resolver quirks are still there, but it's still just a simple interface to the compiler and linker lib. It's still extremely awkward to use, only via the C++ interface, as you have to mixin all the compiler, linker, resolver classes with lambda's for your wanted behavior. But at least it's functional again.
Isn't the fact that without meetup, the group died, proof that they provided some value? It's not like you couldn't send an email to the group saying "let's organize through this google groups mailing list instead", so I assume you needed the marketing features of meetup.
Lightning's core innovation is the use of the Bitcoin blockchain as a cryptographic backstop for payment channels. If the other party in a payment channel stops cooperating, you can broadcast the current commitment transaction to the blockchain, which effectively refunds the current balance back to each party. There's a similar mechanism for enforcing the hashed time lock contracts that make Lightning payment chains possible. I don't know how you could do anything similar with conventional bank transfers.

The non-adaptation thing is recent. Dig down and you will find every building today stands atop the rubble of many previous that were nocked down once they got too expensive to maintain. The city constantly sinks and readily adapted to this. Some might say that need to constantly adapt made venice great. But at some point in the 1950s/60s the "greatest generation" decided to protect the old at all costs. Nothing is ever knocked down and so within only a couple generations everything is in crisis at once.
I gave Arq a go but usability wise it has some catching up to do. It's hard to find an arbitrary file that's been deleted to restore unless you know exactly where it lived on disk. The search didn't work too well for me.
All Must Have Degrees
We're talking within that niche though.

More and more evidence comes out suggesting that it is not as dominated as you think. But if you can substantiate your claim I'm all for it.
This can be easily be solved by pre-signing that transaction and having a third party service broadcast that transaction if you're not online.
Any spammer/automated URL scanner can set their user host was "Googlebot". Doesn't mean it's Googlebot.

Lightning Network Cannot Be a Decentralized Bitcoin Scaling Solution
Essentially, yes. The CubeSat standard specifies dimensions, weight, and max stored energy so that satellite users can focus on their payload and hand off the end result to any launch provider without complicated integration/negotiation.
Not storing passwords on the server removes some of the incentives to break into the server, and makes a quick and covert heist impossible.
It is a system resource to Apple. There are a set of basic "protected" system resources you are not allowed to touch. You can debate if that is an ecosystem you want, but that is what it currently is. You cannot replace the phone dialer, you cannot replace the SMS interface, you cannot modify buttons etc. It's mostly for two design reasons: maintain a consistent UX, and, protect users from themselves. And yes, users need that, and no, it's not forced upon them, you are free to not buy it.

The thing is, that for 99% of the users, the defaults work wonderfully and allow them to be super productive without having to toy with their device like they used to have to in the Windows Mobile and Palm days.
