rythie··on Wi-Fi Alliance introduces Wi-Fi 6
> Wi-Fi Alliance is naming the not-yet-complete IEEE 802.11ax standard as Wi-Fi 6, with ac being 5, and n being 4. One can guess then a is supposed to 1, b as 2, and g as 3, but this isn't mentioned anywhere I can see.

Most 802.11b and 802.11g devices didn't support 802.11a (due to it requiring 5Ghz), so I'm guessing version 1 is 802.11 and 802.11a isn't part of the version numbers.

rythie··on Bullshit Jobs
They have 16,600 employees, with $5.1 trillion under management. They only have 400 funds, which typically would have just one or two fund managers. That's a ratio of 20:1 admin staff to fund managers, assuming two fund managers per fund.
rythie··on OpenBSD disables Intel's hyperthreading due to security concerns
Yes, you're right, I was thinking only about desktop CPUs, forgetting the laptop CPUs are different.
rythie··on OpenBSD disables Intel's hyperthreading due to security concerns
You could just buy i5 based machines instead which don't have hyperthreading.
rythie··on Not Only Is the Mac Mini Outdated, It's No Longer Mini
Probably because you don't have an SSD. It's a shame that entry level models of both the iMac and Mac Mini have hard disks rather than SSDs, because it gives a bad experience.

I have a 2012 MacBook Air, 8GB, 256GB SSD still works great, had to replace the battery, but that's all. I run virtual machines on it, edit photos and video, no major problems with it speed wise.

rythie··on Not Only Is the Mac Mini Outdated, It's No Longer Mini
They don't want to make it NVME only, because they don't want to make a cheap Mac Mini with SSD, because it would eat into their iMac sales.

Right now the Mac Mini starts at £479, but the cheapest with a SSD is £859, don't forget that's without a keyboard/mouse/keyboard.

rythie··on Twitter delays shutdown of legacy APIs as it launches a replacement
It's about getting information in realtime, i.e. @mentions, DMs. Polling for that sort of stuff is time consuming and you'll hit the limits pretty quickly.
rythie··on Nikon versus Canon: A Story of Technology Change
Sony's make mirrorless full-frame, they already able to replace SLRs for many photographers. It's not a trade off as you suggest, because Sony image quality is rated as one of the best, if not the best in the full-frame market. The new "iii" series cameras have much longer battery life than before.

The size of mirrorless cameras is only one benefit, and there's no particular reason that a mirrorless camera couldn't have a big Nikon D5 style battery if there was a market for it.

I don't see any particular reason that mirrorless cameras won't completely replace SLRs in time, a mirror is no longer neccessary, like it was for film. No one would make a new SLR system if they were starting now, and they haven't, all the new mounts are mirrorless.

rythie··on Nikon versus Canon: A Story of Technology Change
Mostly yes, people are locked into their brand through the lens mount and it's pretty expensive to switch. In some ways mirrorless hasn't been considered as good as SLR, with focusing and battery life, though this has been improved a lot recently. Some others still talk about weather sealing, which Sony seems to be lacking - but this is not a inherent flaw in mirrorless systems, but a choice by Sony.

If Canon and Nikon start making full-frame mirrorless cameras, I think we'll start to see a switch, especially if they neglect their SLR bodies and lenses.

I could see silent shooting becoming a requirement in press & some sports, which would essentially accelerate a change to mirrorless in the pro market. Video is another driver for mirrorless, since it can't use the mirror anyway (except in SLT cameras).

rythie··on A proposal to improve Twitter and perhaps the world
I agree with this, on Twitter and Facebook I will very often repost stuff, but on Instagram I never do. However, I do think it's hard to get noticed on Instagram (if that's what you want), due to the lack of native sharing, likes are on someone else's feed and often don't even get a follow from a popular share.
rythie··on Chrome 68 will mark all HTTP sites as “not secure”
Automate what exactly? the point is most home users access their router with 192.168.0.1, they don't have a domain name, nor are they likely to want to buy one. This is now no longer a niche thing that a few people want to do, it's a 100s millions (if not a billion) of households needing to do this to access their own router, so it doesn't say "not secure".
rythie··on Chrome 68 will mark all HTTP sites as “not secure”
Most home broadband users don't have domains and would be unlikely to want to pay for one, just to remote login to their router.
rythie··on Beyond the Bitcoin bubble
We had the dot-com bubble, but it didn't stop the internet from changing everything in fundamental way. Google, Facebook and Amazon are in the top 10 most valuable companies in the world - all completely dependant on the internet for the business model. Granted webvan and pets.com didn't make it, but it didn't mean the internet had failed as an idea.
rythie··on Tesla Roadster
Yes, on the UK one. However, there are many versions around the world. Also, the presenters involved have all left, and are now on the Grand Tour. My point was about halo cars in general, not Telsa's experience in general.

The team at the Grand Tour are going to have to get used electric cars, since I expect all the fastest cars will be electric from this point. If they can't get a loaner car, they'll borrow or buy one, they've done that before.

rythie··on Tesla Roadster
To get featured the list of fastest cars in magazines etc., to go to car shows, to get people into a show room, to get featured on TopGear/The Grand Tour, for kids to talk about at school and so on. All of which boost Tesla's brand (outside the tech echo-chamber, where it is already strong).
rythie··on Ask HN: What is the best way to spend my time as a 17-year-old who can code?
My advice is not to worry about pay in the short term. Once you have some experience pay will be much higher. Think of working somewhere as education essentially, if they pay you minimum wage too, that's a bonus.

I'd find a company with team of devs you can learn from and work there for a few months. You'll be much more employable by the end of it.

As for finding a job, I'd suggest going to tech meetups, startups in particular will be keen on any cheap labour. Alternatively ask your family or parents friends if there is either a position at their work for you, or if they run their own business, if you can do their website.

rythie··on Bitcoin has died 166 times, so far
However, there is much greater than 50% chance that it will.
rythie··on Patching is hard; so what?
Is it so hard though? Do Facebook, Google etc. have this problem too? I doubt it.

Systems need to be designed to be patched regularly from the outset. Yes, defense in depth can help, but it's not defense in depth if you one of the layers is pretty much always broken.

If they are relying on legacy systems that can't be proactively and regularly be patched, they shouldn't be holding that data.

I think part of the problem here, is that we can't see the risks companies are running with our data and goverment doesn't regulate it.

P.S. I do manage systems, though not on this scale.

rythie··on Mozilla’s Send makes it easy to send a file from one person to another
It's a nice idea, though I'd really like to just run one myself (inside the firewall), seems like that would be safer, at least in the eyes of users.
rythie··on SoundCloud's Collapse
Who said you need billions to get started, you need a billion to keep going, when the music industry notice you. Spotify have raised $1.56bn to date: https://www.crunchbase.com/organization/spotify

Which included $1bn in debt just last year: https://techcrunch.com/2016/03/29/stream-with-the-devil/

They wouldn't have raised that, if they were "just fine".

rythie··on Pass: A standard Unix password manager
If you are truely worried about that, you ought to be using 2FA.

The clipboard feature is helpful in pass, when I have someone standing over my shoulder or connected to a projector.

rythie··on Pass: A standard Unix password manager
Not if you use cloud backup or get a virus.
rythie··on Privileged Ports Are Expensive (2016)
Ultimately the issue is that IPv4 addresses are expensive. Allowing multiple users bind to port 80 on different IP addresses, assume you can have multiple IP addresses on that IP. Unless they are private IPs, that's going to be the main issue.

Any practical solution would need a system wide nginx to proxy to all of the tenants, who would run their apache/nginx/node etc. on a high numbered port.

rythie··on SSH Check – public SSH server testing tool
It'd be useful to know what this is likely to break, AFAIK I sshd doesn't log what ciphers people used, like Apache can do. A caniuse.com for SSH would be useful.
rythie··on Too many people are buying cars using financial products they do not understand
That's not the point. The problem is when the person loses their job. A downturn in the economy would lead to job losses and wave of defaults on vehicle repayments.
rythie··on Windows 7, not XP, was the reason WCry spread so widely
Microsoft has recommended turning off SMB1 support in the past: https://blogs.technet.microsoft.com/filecab/2016/09/16/stop-... - though perhaps not prominently enough.

However, you might be able turn off SMB1 support is if you still have machines with Windows XP or 2003. This is a similar situation to SSLv3 when POODLE was discovered, in that the difficulty of getting rid of old protocols, is that of getting rid of the last ones (Though I realise WCry exploits an implementation bug).

rythie··on Ask HN: How do I switch from being a passive consumer to an active producer?
To me, you need come up a schedule a stick to it no matter what. For example when I wanted to do more photography, I started a 365 project [1] to a take a photo everyday and publish it. The first couple of weeks were hard, but after a while I restructured my days, workflow & equipment to suit it.

I'd say, if you want to do YouTube, you should at least do the 1 per week thing. If you are short on time, you can do Q&A/livestream episodes. I'm sure you'd be are aware of Casey Neistat [2], who has said multiple times he wished he'd done daily vlogging sooner.

rythie··on Ask HN: How do you close your side projects?
Do film directors delete their old films? Musicians delete their old music? Photographers delete their old photos? Why would you delete your old code?
rythie··on The iPad Mystery
The iPad is a luxury device mostly.

A smartphone is pretty much essential in the modern world. Even those from poorer backgrounds, will save their money to buy a smartphone. An iPhone is a similar price to other top end devices and arguably better value since it lasts longer (updates/resell value).

A Laptop is essential to learn or to work, it's a solid way, established tool for work.

A tablet/iPad is mostly seen as thing to watch movies on, check social media and play games. All of which you can do on your phone. Apple is going to have a hard job convincing people that the iPad can replace a laptop - I don't think people see it that way.

If every iPad came with a free keyboard cover, they much have some chance, because people would give it a go and see if it works for them. But right now in the UK a iPad pro + keyboard is more than twice the cost of an iPad 9.7 (to which you can't add a keyboard later - for some reason).

rythie··on Hospitals across England hit by large-scale cyber-attack
Seems like it would be pretty to fake up one of those screenshots and put it on Twitter, in the hope someone would pay it.
