fivesigma··on Atom 1.9 and 1.10 beta
I love atom, I use it daily and it is my editor of choice for web stuff.

But think of how many software abstractions/levels each line of atom code has to go through. I mean, each keypress probably produces in the order of 100 million CPU instructions in the metal (number pulled out of my behind but you get the idea) just to display a single character. Is this what progress looks like?

I guess there's a balance between developer comfort and software efficiency.

fivesigma··on Your Phone Has an FM Chip. So Why Can’t You Listen to the Radio?
Agreed.

JS on a website that is otherwise not an app has its use cases ie. tabulated data, search, filtering, realtime data etc.

But a static website displaying a simple article has no fucking business running any code other than HTML/CSS on my computer.

fivesigma··on Sun's galactic journey linked to mass extinctions (2013)
Spiral arms aren't static objects, they are a denser region of the galaxy as stars pass through them. There's also a small speed variance between different systems, so on average it all evens out. Then there's dark matter which adds an additional factor to the orbital speed.
fivesigma··on A tale of two cryptocurrencies: Ethereum and Bitcoin’s ongoing challenges
>Can someone explain to me how Ethereum fulfils the "dream of having a truly decentralised web"?

It doesn't. It's hyped up bullshit.

Every Ethereum node runs the exact same code (single threaded too) with heavy computing and storage restraints. There's no sharding or load balancing. Can you run the entire reddit website on a single 90s computer? The answer is no.

Don't get me wrong, Ethereum is an interesting experiment and blockchains are useful for a number of things, but the notion of "lets put everything on the blockchain" is a shitty, terribly inefficient solution looking for a problem.

fivesigma··on CloudFlare Suffers Major European Outage
More like, "Half of websites having problems in the EU".

Cloudflare is that big.

>WPA/WPA2: 3177.6 kH/s

22.5 minutes (11.25 on average) to crack a randomized 8 hex digit password that a good number of wifi modem/routers come with (mine certainly did)

fivesigma··on One Billion Drive Hours and Counting: Q1 2016 Hard Drive Stats
This is disturbing.

What happens once they are able to wipe SMART data? Is that even possible?

fivesigma··on Estimating the Revenue of a Russian DDoS Booter
Here's how it could be done:

Spin up a hefty AWS instance and connect to every single IPv4 IP while sending a HTTP get request on successful connects with a Host matching that of the domain. There are only 4 billion IPs. Look for successful code 200's with the same headers and content as the original website. Easier said than done though.

Btw, this attack can be prevented if you run a drop-all firewall and only whitelist the IPs listed here: https://www.cloudflare.com/ips/

fivesigma··on Dropbox’s Exodus from the Amazon Cloud
Let us hope that the IoT buzzword doesn't get abused as much as "cloud" has in the past 4-5 years.
fivesigma··on Living Without Atomic Clocks
Both velocity and gravity (distance from the nearest planet/star) affect time.

It does, but the difference is negligible unless we're talking about the surface of a neutron star.

fivesigma··on What Happened: Adobe Creative Cloud Update Bug
Tried that, didn't work. My guess is that Photoshop ran some kind of script that re-enabled it. I went to great lengths trying to gracefully disable all the CC crap before I gave up and rm -rf'd every damn file/directory containing adobe.
fivesigma··on What Happened: Adobe Creative Cloud Update Bug
On OSX with just Photoshop CC installed, there's around 10 adobe related processes running at any given time, all the while making connections and sending data to both adobe and non-adobe (CDNs) IPs. And that's AFTER you disable all of it's settings including run at startup. There's even an adobe Node.js instance (wtf?) constantly running and using CPU.

I don't take kindly to my system being commandeered, so I cancelled my CC subscription, removed their bloated, slimy POS software and bought Affinity Photo.

fivesigma··on Socat: “the hard coded 1024 bit DH p parameter was not prime”
That would be 10^80 which is much, much larger than 2^80.

Unrelated, but 2^80 isn't that astronomic when it comes to computers, considering that the entire Bitcoin network has performed 2^84 hashes.

fivesigma··on How Tumblr Can Save Yahoo
I guess they were unable to grok responsive design CSS practices, even at a $1b valuation.

Case in point of some people who get it: medium.com

fivesigma··on How Tumblr Can Save Yahoo
Who would've thought that blog posts about the evil patriarchy cannot generate enough revenue.

Also the fact that tumblr blogs look like they came straight out of 2006. We have mainstream 24-27inch screens with 1920 horizontal pixels now. Why do most tumblr blogs look like geocities-era thin vertical strips of annoying gifs filled with tiny blocks of hard to read text?

fivesigma··on IPv6 celebrates its 20th birthday by reaching 10% deployment
I bet most of those users are on mobile networks. The need is very apparent: every mobile device needs to have internet access, and there's a lot of them with more being activated every day. Mobile providers don't have enough IPv4 addresses to support that and carrier-grade NAT is even more messy than IPv6.

Most residential ISPs that support IPv6 make you go through hoops to enable it.

fivesigma··on Tim Cook: Apple products aren’t made in China because it’s cheaper
Nice PR misdirection, Tim.

Apple is the kind of company that will skimp on updating base storage to 32GB on their €650 smartphone because it might reduce their margins by 0.001% (number pulled out of my behind but you get the idea).

It certainly IS because it's cheaper.

fivesigma··on Scott Aaronson on Google’s new quantum-computing paper
TL;DR version: If there's any quantum phenomena going on in that device, it is only happening within the 8-qubit domains and not between them.

Bonus food for thought: how much more of a speedup factor would an ASIC farm provide compared to a general purpose CPU for that particular use case if you threw $150M on it?

fivesigma··on DRAM chip failures reveal surprising hardware vulnerabilities
Thank you Intel for disabling ECC capabilities on consumer grade CPUs.

With smaller and more dense DRAM chips every year, it takes an even smaller amount of disturbance to flip a bit. ECC needs to go mainsteam yesterday.

fivesigma··on I worked in a video store for 25 yrs – what I learned as the industry died
I do not accept the legitimacy of arbitrary region restrictions. It is still the moral thing to do and much faster/easier than torrenting.
fivesigma··on NASA Orders SpaceX Crew Mission to International Space Station
10000% by mass is a more accurate figure and since you like dimensional scaling, that's 364% scaling.

The GoFast Rocket weighs 350kg. Scaling it by 35% (1.35 ^ 3) would make it weigh 861kg. The rocket you mentioned weighs between 30 and 70 _tons_.

I'm not sure you understand how anything works.

fivesigma··on NASA Orders SpaceX Crew Mission to International Space Station
A 160km altitude cubesat would require a minimum 7.8km/s of delta-v. Anything less than that and it will burn up in the atmosphere after a few orbits. GoFast Rocket achieved a top speed of 1.6 km/s (3580 mph).

It needs to go 4 times faster, and no, a 20% larger rocket won't cut it. 20000% larger by mass would be more like it. It also needs a 2nd stage burning liquid propellant with high specific impulse which is way, way harder to build than a dumb solid propellant rocket.

Noone (not even governments) has been able to send a single stage rocket to orbit.

fivesigma··on NASA Orders SpaceX Crew Mission to International Space Station
The difference between such a ballistic trajectory (1/5th of escape velocity) and LEO is huge.

>you don't need to scale "go fast rocket" up by that much

My napkin math says you need at least 2 orders of magnitude more fuel mass which classifies as "a lot"

fivesigma··on 'Power Over Wi-Fi' named one of the year's game-changing technologies
The inverse square law is a bitch.
fivesigma··on Square jumps in market debut
Because then the IPO underwriters (big investment banks) wouldn't be able to make a shitload of money on top of their IPO fees.
fivesigma··on SVG Mask Artwork of the Intel 4004
The hard part of a service like Facebook or Twitter is actually getting the users. Scaling is a problem that has been solved ages ago. It is something that will come naturally as you throw money/people on a service that is growing organically.
fivesigma··on 21.co Bitcoin Computer Now on Sale
They should be forced to work on an old Windows XP laptop with a tiny trackpad for a month.
fivesigma··on 21.co Bitcoin Computer Now on Sale
They should remove bullshit claims like "provides you with a constant stream of Bitcoins". People might actually think that this is a miner, which it really isn't. It is the equivalent of digging for gold with a rusty spoon. You could spend 10 times less on an exchange and that would provide you with a bigger "stream of Bitcoins" than what this thing could make in a year.
fivesigma··on List of secure websites
So all applications to the HSTS preloaded list are hardcoded in that json.

How big will that file get in a few years? Looks like the first addition of user submitted websites was done over a year ago.

I wonder how ubiquitous HTTP/2 (TLS mandatory) will affect this.
