There are many strategies that are difficult to encode into an algorithm. When I briefly did day trading independently, my most profitable strategies played on public perception and (over)reactions to news. Those things are very, very difficult to properly automate (though many companies try, with varying degrees of success).

You can lock-in your upgrade eligibility w/o actually installing Windows 10.

The WinToUSB tool (http://www.easyuefi.com/wintousb/) can create a bootable Windows 10 USB thumb-drive (or hard disk drive, which is much faster). You boot from this drive to lock-in your entitlement w/o actually having to upgrade to Windows 10. (You must use the Windows 10 "1511" update to do this. The earlier Windows 10 version won't activate w/ a Windows 7/8/8.1 product key.)

Create and boot from a Windows 10 thumb-drive and use the "Activate Windows" functionality with your existing Windows 7/8.1 key. This will lock-in that PC's Windows 10 entitlement w/ Microsoft's servers. No changes are made to your existing hard disk drive.

If you're paranoid like me, you can even disconnect your hard disk drive while you perform this procedure to ensure no changes are made.

I validated the "digital entitlement" to install Windows 10 after performing this procedure on a PC. I put a clean hard disk drive in it, installed Windows 10 from scratch, skipped entering the product key during install, and found that the machine was "Activated with a digital entitlement" after installation completed.
Ask HN: When getting a new job – what to do about a bitter boss
Short and sweet since I have never done this before. Long story short i'm getting a better opportunity than where I am currently, but my current employer is kinda bitter about it. The reality is he lives in a bubble of reality he created for himself. I really hate to leave with that kind of situation, but I really don't know what I can do about it. Any advice?

EDIT: It's not to say that he was always bitter. He actually is a great guy and does a lot for his people. He is just in a tough spot, and me (as a key person) leaving is really hard on him... and I'm certainly seeing the bitter side of it.
It's important to recognize pretenses of objectivity.
> Spacemacs takes so long to load that it's laughable.

Emacs is typically started once, and then you open files in the same instance. With vanilla emacs you can use `emacs --daemon` to start it as a server, and then use `emacsclient` to open files. That way it should open pretty much instantly. I'm not sure what Spacemacs calls those.
> Ads are included in corp mail and POP3/IMAP access is disabled. You have to use the web and mobile clients.

Ah, that's why Yahoo has gone to hell — emacs users don't stay with the company. You see, emacs has 8 different mail clients: rmail, gnus, mh-e, wanderlust, mew, vm, notmuch & mu4e — and no true emacs user (not to be confused with no true Scotsman …) would want to read email in anything but his favourite text editor.
You can make money having by having better access like the HFT firms or by having data not widely available. You can also make money by applying well known principles more intelligently than others. This latter approach usually requires a lot of money. You can't afford retail brokerage costs when you're in a highly crowded and competitive trade.

The best way to make some money as a personal trader is to take advantage of the liquidity premium in one way or another. Because you're trading money in the 5 or 6 figures rather than the 7 or 8 figures, you can take advantage of smaller opportunities without thoroughly distorting the market with your own trades. These smaller trades usually require research and market insight rather than clever algorithms. These trades are usually on financial instruments that don't have a lot of easily accessible data to build an automated trade on top of.
This depends on the amount of communication. Steganography can attach a noise-like information stream to another, innocent stream, like a stream from a webcam constantly scanning one's backyard "for security purposes".

It's a whack-a-mole problem, and the moles always have a pretty fair chance.

This, of course, keeps the encryption in the hands of the technically savvy and motivated few, while the majority will have to use security with backdoors, and possibly other holes, for the convenience of the snooping by the government and online thieves alike.
Ah I misread the inclusion of "gcc 4.9.3" as saying it was an upgrade, rather than just stating its continued existence. Thanks!

The home computer market was originally a hobbyist market.
If she wants to do software then Python with one of the many excellent free and non-free books for kids available. Just look them up on Amazon.

If she wants to get into hardware start with a RPi or Arduino.

Also get her running Linux. Start with something simple like Mint or Ubuntu. Teach her how it is "like Windows and OS X" but a bit different. Do some basic command line stuff like making a folder, opening a file, etc.

Setup Minecraft which I would assume she already plays if she likes tech. Show her mods, maybe even a little Java to make mods although I feel Java with its strict OOP and compile/run can be a bit daunting for even an adult so maybe wait until she understands Python a bit.

The main thing is just explore all the different things. Tech is awesome today as if you have a computer you can get so much stuff free thanks to the FOSS community from the OS to everyday software to programming languages to books etc. And little hacker hardware like the RPi is affordable by almost all with a little spare income.

> If its possible to be a profitable independent day trader, and we know it is because many are, then it should be possible to code the rules you follow and become a profitable algo trader.

There's actually a logical error here: if trading results were essentially random, a certain subset of traders (including day traders) would, at any given time, have profitable records. But you would not be able to derive (and, therefore, implement in code) any set of rules which would make automated trading profitable. You would just either be lucky, or not, as an algorithmic traders just as you would as any other kind of trader.

Now, I'm not saying that trading profits are random, but the existence of some profitable traders does not mean that there are rules you can deduce from their behavior that will guarantee profitable trading when implemented by someone else (either in an automated system or otherwise.)
Then the "where are you willing to work?" becomes an important factor. There aren't a lot of "high-precision mass spectrometry" work in a lot of towns.
This is true. People want to believe that everyone is created equally. No. People are not equal. Black men, on average, have larger genitalia than other ethnic groups. How can you say all men are created equally?
I dunno. After many years of music filled flights, I've recently starting using earplugs, instead of music, with my Bose noise cancelling headphones and have found it quite rewarding. I can't sleep on flights, but the kinda silent (boring) time has been great for closing eyes and reflecting on events/work/etc.
Ask HN: What service or product would you be customer 1 for?
There’s plenty of talk online about how important moving from 1 customer to 100 is, or 10 to 1,000. In my own personal projects though, it seems like the biggest challenge can be in just moving from 0 to 1. That said, rather than using one of my ideas and looking for customer 1, I’d like to work backwards from where there already is a customer 1 looking for a product.

So, what product or service would you like to see exist that you would be willing to spend money on? It could be personal or business and the price and theme are irrelevant. It should be at least potentially usable by other customers (i.e. not something heavily customized like a personal website). Also, are you willing to leave your contact information in the event that someone reading would like you to test/buy said product/service if built?

I for example, would be willing to be customer number 1 for a text to speech service for public blog and news article posts. You could just pay hundreds of dollars per hour for online professional services, but my thought is that a lot of people will want the same articles, bringing down the shared cost. (Contact info in profile).
Everyone having an opinion and there being opinions doesn't mean there isn't anything else. Design-wise any work can be broken down into all of its possible abstractions and inferences, just as a user interface can be measured by use cases. There is also technique, originality, coherence...These are factual and measurable, and any feedback regarding them would not be some opinion anyone could either take or reject based on their opinion. It would be stating a fact.

If you're an artist, the love for your work far outweighs anyone's opinion. You should be doing what would make you love your work even more. And it will resonate with those who love the work also. For this to work, you must have good taste. Love and taste are not opinions.

If something truly holds no empirical value or weight outside opinion, then you've just proved its worthlessness. If it only matters as much as opinions, it doesn't matter much. Do whatever you want.

Points of view, food for thought, and expert advice are not opinions. And none of this is my opinion either. I am stating what I know.
Return Any (Task-Like) Type from an Async Method
I was thinking prions might be a good candidate for OOL.

Early Earth apparently was rich in amino acids and so chains of them may have formed natural proteins. So a prion - a functional protein that can change other proteins into its shape - would be able to set off an evolutionary fitness search for the protein which could best "convert others" while resisting being changed by others.

The other reason is I'm skeptical of starting with a polymer type information encoding molecule. It seems too unlikely that any minimally viable genetic molecule could assemble by pure chance and there is not a good way for information to flow from the environment/cell -> genetic polymer.

>> which I think requires a new narrative and philosophy for what human equality means and a way to ground it on something more fundamental than a wished-for genetic similarity.

I'm sorry but that sounds mighty dangerous. Human equality was never grounded in genetic similarity; you do not need to know that your salad mix of ancestors are different to others to understand that every human today deserves equality. Sure groups of people may be different - like culture - but once we start thinking that one is better than the other, we get hierarchy, and we get superiority. It's not as if it doesn't exist today at varying degrees but careful that it doesn't gain mass momentum. It's a slippery slope and one we've gone down far too often.

Great feedback! You might want to take a look at upcoming Issue Boards (https://gitlab.com/gitlab-org/gitlab-ce/issues/17907) and see if that works for you.
I am surprised they did not add the line "think of the children" in there somewhere...

Meanwhile in the real world, criminals will resort to sending encrypted USB sticks via post, or carrier pigeons, or implanted in mules. There is always a way around these things for those that absolutely do not want their communications compromised. It is safe to say that any criminal enterprise knows that live electronic communication of any sort is likely to be compromised.

Also of concern, is that criminals will now have extra attack vectors to sensitive data, because if encryption has to be weakened for Government, it will be easier for other parties to exploit.
Thanks! That's a very insightful reply
> If its possible to be a profitable independent day trader, and we know it is because many are

You're forgetting about the many that aren't profitable. You're also forgetting about the majority that are less profitable than the market average. The latter is probably the easiest to overlook. Yes, they are technically profitable, but so are packaged portfolios of stock held for long periods of time. If you can't be more profitable than someone who puts in zero effort, then whats the point of putting in more work?

There were times, when such a system might have outperformed x86 hardware (Sparc, Power). And even if not strictly competetive, people who care about writing low level software should be delighted working on something different than x86. I certainly would like to work on an Arm64 system, ideally with 8+ cores. That should be quite interesting.
Can't find the original comment but somebody wrote here time ago that some HFs let you run on their infrastructure (keeping 85/90% of any profits) if you can prove to have a valid strategy. Just out of curiosity, I could not find any other information about this, is it a thing that actually happens?

yeap, but I have a nice .ssh/config that does wildcard masking , and a few other things to make sure I can log into servers without remembering which SSH Key I need to use, and what username.

e.g. I use the following snippet for my dev build boxes - they are rebuilt all the time, but I need to login and check system state from time to time.

Host 10.250.60.*
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
IdentityFile ~/.ssh/local-dev-key
User build

If you are implementing multiple SSH Keys, remember that a -lot- few people will have keys on GPG Cards, YubiKeys and other devices, not just on disk.
You have gcc48 and gcc49 in the packages.
There are lots of successful software developers too, but writing out a series of rules to automate writing code is not going to happen soon. Unless day trading is substantially easier than programming, an autonomous robotrader that can make money seems unlikely.
I'm going to play Devil's Advocate here, because complaining about intrusions on our privacy and how ineffective they are, has become de rigeur on HN and Reddit without much dissent.
There clearly is a security problem in Europe at the moment, and I'm assuming that the attacks are not being organised by the security services.

So will this bill reduce, increase or have no effect on the attacks? If not, then what would reduce the attacks and why are the authorities not doing it already? If it will reduce the attacks, how much does it have to reduce them before we accept the intrusion on privacy as a necessary evil?
This is a fairly obvious sacrificial anode bit of the legislation. They'll drop this, while making the "provide the keys" bit of RIPA stronger.

The state's enforcers do not fear doors, because they have boots for kicking, and stout legs to fill them. Even the heavier doors can be breached by prybar, ram, cutting torch, or explosive.

But when your bathroom door is protected by 256-bit encryption, the peace of your metaphorical deuce-dropping is (statistically) guaranteed until such time as the sun leaves the main sequence and devours the Earth.

The states conveniently ignore that kicking down a toilet door to pick through someone's poo and count the peanuts is not generally beneficial to anyone's security, especially when holding out a net under the appropriate sewer pipe could usually achieve the same results with less public outrage.

In any case, those with truly incriminating poo-peanuts will likely burn them, or head off into the woods with a trowel, and your toilet raids will only end up menacing those who linger too long in the stall, solving sudoku puzzles or practicing toilet-square origami, or whatnot.
Maybe if it's the only thing you show someone but most tutorials will start with hello world! and then progress to variables, string interpolation, expressions through a sequence of:

1. Try changing the statement print your name.

2. Having to type the same thing over and over is unnecessary, we can save it in a variable.

3. You can use variables inside the print statement through a process called string interpolation.

4. In addition to strings, variables can hold many types of values, including numbers.

5. Operators can be used to manipulate values. Do some math with the variables.

6. Receive input and save in variable.

From there you can go to conditional statements, loops and functions.

Hacking the HVAC system to raise the temperature of the tape storage facility to destroy magnetic tape backups in place was quite the idea.
GPUs are much closer to von Neumann machines than to anything people typically deriding the latter have in mind

The GPU architecture was developed to enable the application of many von Neumann machines to a particular type of "mildly embarrassing" parallelism. I'm not so sure that we couldn't greatly benefit from going a little further in this direction.

Right now, I see a mainstream architecture that does fairly well with read parallelism, with a need for more efficient two-way communication between separate threads. What if we had better hardware support for the things we're trying to do with with the Disruptor that came out of HFT? This would also benefit multiplayer games.

I do get that there are a bunch of other companies that license ARM but it seems like Intel is the overall winner.

I also don't think Intel would switch to MIPS or some other existing platform given how much they've invested in ARM.

Humans once opposed coffee and refrigeration: why we often hate new stuff
This is a wonderful read, thank you for sharing it. I'm genuinely curious about this, if any Valve insiders have insights:

> That’s why Valve is flat...You have
the power to green-light projects. You have the power to
ship products.

Is this really the case? On paper this sounds great. I've worked at companies that have a similar motto. Power to the employees, power to the developers. But it usually just means the hierarchy is unspoken and assumed. No structure means no one to go to with disputes about your job, problems with co-workers, etc. It can be worse than a traditional hierarchy because everyone sells the "flat" motto to newcomers, but as soon as you join you learn the hidden politics. The cognitive dissonance can be soul crushing.

So is Valve truly flat? Are there any examples of relatively new employees spinning up teams and shipping unique ideas? If it works, how do you handle inter-personal employee issues?
