"Finally, they devised a high-speed gantry mechanism — an H-shaped frame powered by two motors, connected to a motion stage that holds the printhead."

It seems a CoreXY or H-bot design, I always believed that the issue with this design (like any cartesian design) is with the limits of acceleration and "drag" of (relatively) massive parts, particularly because the X and Y axis have not the same weight/mass when changing orientation of the movement (the Z is less of a problem, at least with "large" surface prints, the issue here is only around precision), and that was the reason why Delta's are usually faster.

Maybe a Delta with that head/printing gear can move even faster ...
And the impact remains minuscule outside of the remote desktop scenario.

The attacker must already have access to exploit this, and one would have to be utterly clueless to expect that an attacker wouldn't be able to get root some other way.
Sure, but don’t lie about it.

"Your idea is not valuable, at all."

If execution is all that matters your idea isn't good enough.

I don't care how many times people keep claiming that execution is all that matters, it's still wrong or it becomes tautological, like saying. The key to success is being successful.

Good ideas are often shitty ideas until they are good. What makes them good isn't just execution but timing, luck and so many other factors.

Failing to understand that is a bigger problem than the few people left who think the idea is everything.
Code Forces is an ugly, ungamified site but the calibre of its contestants is of a far higher grade. If you can do well there, you'll have no need to ever again worry at your ability to solve smaller coding-related problems. Silicon Valley tech company interviews will also feel easy in comparison.
I am sensitive to the investment aspect, because it is true what you thought you were buying has changed and possibly in a way that makes it less valuable. Ultimately, it’s not what you actually bought so that’s kind of on you.

But I wonder if developers offered to buy neighboring houses at the same time they buy the first house, if that would help at all. Then the neighbors have the option of not losing any value because of the shadows that will go up or whatever. This would require by-right type laws where the developers could trust that housing is actually possible to build on these lots, otherwise buying multiple properties may be too big of a risk.

I suspect NIMBYs might like this idea even less since it could more drastically change a bigger part of the neighborhood, but it seems like it would at least partially address their stated concerns of neighbors being financially impacted.

How about performance? Bugs that might come up due to the implicit nature of Rails? Just curious, since you have seen both sides.
Having worked at a university at one point I can understand how shitty security is at virtually all universities. But Stanford claims to turn out brilliant technologists (in addition to these overpaid MBAs) yet apparently doesn't hire any.
My opinion has nothing to do with this, because the distinction is extremely important as a matter of fact:

Not only is it fully legal for a transition team to work with other state leaders, but in fact the Obama administration explicitly stated in no uncertain terms that they don’t have any problem with it:

This video has been going around showing this:

Obviously Flynn pleading guilty to lying IS genuine news, but we’ll have to wait and see exactly what it entails. But make no mistake: This news article made TWO huge claims of news events, and you can see them even in the title of the article. One wasn’t just wrong, it bore the exact opposite message of reality (Trump campaign subverting Obama’s authority, vs the incoming Trump administration working with foreign leaders under the direct blessing of the Obama administration).

I’m not here to defend Trump or Flynn or anyone else, except advocate for the apparently crumbling notion of journliastic integrity. It’s sad how little of it remains. If you want to see Trump impeached, by all means we should continue investigating and bring to light facts. But please, it is important to get the facts right.
High Sierra is the first Mac OS update that I haven’t downloaded on the first day. Still on Sierra here.
It is crystal-clear a type error, but here's an article breaking it down:

https://objective-see.com/blog/blog_0x24.html notes that od_verify_crypt_password is called with an error check expecting 0, but on failure it returns 0x1. The code then goes on to a "success" path with an "update".

This is a classical type mismatch that C and C++ pre-2012 are so famous for. Someone writing this program where both modules were in Rust would have used Option or Result and this expectation mismatch wouldn't have existed.
Indeed, I think so many don't really consider the consequences of their actions. If this lawsuit is successful on the desired basis that private companies operating semi-open platforms are legally deemed as "Public Forum" then that is a huge game changer for everything.

I have an extremely positive view of the EFF, but in this case it really looks like they're trying to have their cake and eat it too. A key statement in the article is, "It’s the president’s (and other officials’) use of Twitter that is subject to the First Amendment, not Twitter itself." Yet their entire argument states quite the opposite - that this entire thing is contingent on Twitter being defined as a sort of legally defined Forum for discussion so that first amendment law is applicable. That categorization most certainly has major implications for Twitter and all major social media for that matter.

The thing about issues like net neutrality and the NSA is that, so far, they've covered their legal bases. I think dedicating legal resources to something, that the organization itself presumably has no expectation of a positive ability to influence, would be a far greater travesty than pursuing something where they believe they can effect positive change. The EFF, for how much they do, are incredibly small and underfunded -- they have to pick their fights.
Yeah but gender and race diversity (the qualifications mentioned in the article) still discriminate against poor white males.

I am fairly certain that a poor white guy would have a very different perspective from one who grew up in a life of privilege but that socioeconomic diversity doesn’t look as good I guess.
Yea, what?!

Smoke and mirrors, baby!
I still use rsnapshot to manage such backups. I like that I can use an old Mac to run it. Doesn't ZFS require more from the system, RAM particularly?
This only goes so far in the bay area. Sooo many companies are dumbly opening shop in those tired places like Sunnyvale and PA that now take 90 minutes to get to from almost anywhere. No amount of podcasts or audiobooks can save you.
This is pretty fascinating. I've been mulling a change in careers bc I believe over the next 20 years this will become a massive industry. Do you see GM Cruise hitting their 2019 goals? How close are they to producing ~1k - 10k cars with this tech in multiple cities? I find the 2019 targets incredibly aggressive. 5-10 year timelines seem more practical. Also whats the alternative to ROS, why isn't it good for time critical operations?

I’d like to see some close ups of the prints. In the video you can see the print bed vibrating like crazy, and each layer can’t be anywhere near solid if there’s a tenth of the time to cool, even with a fan.

I wonder if you could have a something that squirts a fine jet of liquid nitrogen, just behind the print head? Expensive though I suppose.

Here's some tips:

* They use tools like Buffer to be active on several social media accounts at once.

* They're active on Stack Overflow during working hours.

* They use work as fodder for blogs and presentations.

* They seek out challenges at work.

It just comes down to using your time wisely to achieve several goals at once.

If this is what you want, then I'd recommend every morning to plan out your day and keep track.

I stand corrected.

To nitpick, there is more data in the keychain than passwords and credit cards. But I think having all your passwords and credit cards exposed is probably bad enough.
It's not inherently async, but it supports async. Although database support for that isnt great, so I'd recommend just sticking to synchronous stuff for now unless you don't mind using raw SQL.

If it were me, I'd probably use something else before I tried to squeeze that much performance out of Python at this point to though. I hope library support catches up and it becomes more convenient, but I don't think a predominantly synchronous ecosystem has really successfully transitioned to async before.
Flask for a CRUD ?

I'd agree with you for a very simple API (like a simple slack/irc bot), but for a CRUD, you'll need to write a LOT of boilerplate code with Flask
At my previous company, where raising money and making sense of accounting was a non-trivial, the Chief of Staff was (like the CEO and the CFO) a former investment banker for +10 years. He definitely felt like the #2 of the company (ex-aequo with CTO & CFO) and not an executive assistant.

In practice, he was in charge of internal communication with non CxO people and the CEO, and a lot of things that the CEO had to do that wasn’t direction external relations (typically press): preparing financial documents, coordinating teams with legal, team morale, etc.

I’d suggest “The Color of Law” for a better rebuttal to your argument than I can provide here. Zoning absolutely has been an important tool in establishing and maintaining segregationist housing aims where more explicit policies like restrictive covenants were rejected by the courts.
But the trade-off isn't usually worth it.

The time you save initially you'll later spend fighting the framework or debugging its internals.

Python's "explicit over implicit" scales a lot better, especially with large teams.

The central problem here is that Stanford is saying one thing and doing another. The central question, which isn't asked in the article, is why. Stanford is creating an exclusive, private club, as is their right, but not being upfront about the rules of exclusion. More importantly, the reasons for exclusion.

> The key to the team’s nimble design lies in the printer’s compact printhead, which incorporates two new, speed-enhancing components: a screw mechanism that feeds polymer material through a nozzle at high force; and a laser, built into the printhead, that rapidly heats and melts the material, enabling it to flow faster through the nozzle.

That's the exactly what is making this new 3D printer 10x faster

Could this be solved by adding refrigeration? Couldn't they run the machines much faster if it was printing in a colder environment?
>I wonder if you could have a something that squirts a fine jet of liquid nitrogen, just behind the print head? Expensive though I suppose.

Maybe - just a semi-random idea, mind you - a Ranque-Hirsch (or Vortex) tube (and a source of compressed air) would be enough and possiby be more practical:

Then you should from the start make a policy not to keep any logs. The only use of those logs is to prove that you are guilty so it makes no sense to keep them.

Even if you didn't do anything illegal, they can be used against you anyway.

This is a really excellent analysis. The question isn’t whether Twitter in general is subject to the first amendment—it isn’t. It’s whether government officials, by creating a Twitter account, have in effect created a public forum. Having done so, they can’t restrict speech on it. This isn’t a far out argument, though it might seem like one. Public forum doctrine is well established.

To use a meat-space analogy. Say the government set up booths in a mall for public officials to make speeches. Could the government then kick out people who bring in pro-abortion signs to such a speech? Probably not. While there is generally no free speech right in a private venue like a mall, where the government creates in effect a public forum on private property, it has to abide by the First Amendment.

Were the law otherwise, government officials could insulate themselves from criticism simply by making speeches in hotel ballrooms and the like. That is, in effect, what Trump is trying to do with his Twitter feed.
I wrote a tool called Snebu (www.snebu.com), which is intended to give you the same thing as rsync + hard links. Uses find and tar to grab file metadata and retrieve files, on the back end it stores file data in .lzo compressed files with all metadata for each snapshot (including symlinks, hardlinks, etc) stored in a sqlite3 DB file.

The design goals were to make something that didn't store data in a proprietary format (you can analyse the backups using straight sql commands, and access the data using lzop), and to be able to back up systems without installing a client agent on them, and support compression, and avoid filesystem issues you run into with a large number of hard links (such as https://news.ycombinator.com/item?id=8305283). So far I've been using it to back up a few dozen RHEL 4 - RHEL 7 systems over the last couple years without issues.
I really dread upgrading Django. We have a codebase that has been with us since the 1.3 days and each time there's an upgrade, someone on the team sets about one month aside to deal with all of the breakage. You could say that this is our fault for "doing it wrong" but we just wanna get stuff done. Sometimes the only way to do it that we could figure out was by doing something that Django later decided we shouldn't have done.

Going to Python 3 is going to be the biggest annoyance yet.
A lot of things of business value go like this, for example: go build this UI in React, etc. You don't need the ability to significantly return something back to academia to do that. You just need good coding mechanics.

This is the biggest failing of modern debate. It seems like we've thrown compassion and putting ourselves in other people's shoes and now just say "your view is stupid, change it". Imagine someone presenting that to you? Is your immediate thought "hm, you're right! convincing point!" or "Go fuck yourself"?
Doesn't work as well when you just want to pop out a quick small prototype so you can test it, iterate, and do it again, but definitely that works for some applications. And as they mention, path optimization can also help here. As a contrived example, if you're building an upside down extruded "T" shape, maybe you could work on building up the stem as high as possible as quickly as possible, and spending the "cooldown" time working on extending and building up the base. I'm not aware of any 3D printers that move beyond the simple "build from the bottom up" approach[1], but it seems possible to take into account the bulk/size/shape of the printhead and do some advanced things -- if the payoff is there.

[1] I also know approximately nothing about this space, I'm not speaking from an area of expertise, just novice theory. Maybe this is already being done or maybe it's simply impossible because the printhead is just far too bulky.
From the article, it turns out that their opinions eventually did not matter. It would be nice to change their opinion at least so they aren't bitter about it.

Currently working through this and last year in Perl 6. Really good fun.
Ok, lies are unacceptable.

To play devil's advocate here: the press and the public do not want to hear that tech companies pay 7 digits of monthly salary to attract some talent. Nor do they want to hear that Universities have to offer merit based scholarships to attract top students, otherwise these students will go elsewhere.

Companies advertise their diversity efforts but not the salaries of their executives. Stanford said what the public wanted to hear.
If you have a large amount of data to backup, cloud storage may be too expensive.

My data set is about 8 TB (my wife is a professional photographer), and it would be too expensive to keep in S3, so I have an "offsite backup system" that is hosted at my in-laws. It's just a RaspberryPi + an 8 TB drive encrypted with LUKS (in case it gets stolen or tampered with).

Every night, the RPi syncs the data from my house with rsnapshot (which is a TimeMachine like tool that uses hard links with rsync over ssh).

Because of how rsnapshot works, I can always go there and look for a file in one of the directories: it looks just like the original hierarchy, and I can just browse the filesystem as I would on the original system.

I also don't have to "trust a 3rd party" that the data is really there. I remember some posts on HN about people who used some backup services successfully... until restore time. I'm always cautious about the magical "set it and forget it" service that is a black box.

The first sync has to be done "on the premises" because of the sheer amount of data to transfer, but then the few daily Gigs of data can easily go over the net while everyone is sleeping.

Someone blocked by president trump can still read his tweets because Twitter does not prevent you from having multiple accounts.
On the notion of free speech, twitter does not block users from tweeting stances in their own feeds.

To allow this should mean EFF should also require fox news to provide a 1 hour block at midnight that allows 1 minute video segments from angry people that want to shout at the president. It's not going to happen.

The first amendment was about making it legal to shout from the rooftops, but not a requirement that all mediums re-shout it for you.

If you want to start a newspaper in the US, no one is stopping you.
I think you're confusing blocking and muting.
> shitty security is at virtually all universities.

Shitty compared to whom? Who are the examplars of information security universities aren't matching? Academia security doesn't look so bad compared to governmental or corporate security.

Security involves trade-offs and some of universities' lower security is a conscious choice to not impair academic freedom or collaboration.

> apparently doesn't hire any.

If their graduates are as good as claimed, the University can't afford them. And many wouldn't want to work there because most of the University's problems are not interesting.
For better or worse, it _is_ a proxy for many things. But one that i think is most relevant to a typical job is the ability to see something that is sometimes fun, sometimes boring, and sometimes challenging through to the end. Typically staying put in one place while doing so. Its not intended to be vocational training, but in a sense it matches very well with what's expect of the typical employee: Show up consistently, deal with stress and various people and tasks with an ability to see it all through, without quitting or pissing too many people off. If you can cope well and make it through undergrad, you can likely handle a vast array of jobs.
Let's try to make sense of Verge's points:

1. Creation of fast/slow lanes

> If you read carefully, you’ll notice the FCC isn’t even trying to debunk the creation of fast and slow lanes. It’s just trying to debunk that they “will worsen consumers’ online experience.” That’s a matter of opinion, and clearly, we all know which side the FCC lands on.

Verge says: FCC has stated an opinion and we all know what kind of people have an opinion that doesn't match ours lol.

2. ISPs will block sites

> The FCC is trying to repeal a rule that stops ISPs from blocking websites, so the commission absolutely can’t guarantee internet providers won’t do that when the rules are gone. But despite saying this “won’t” happen, the answer goes on to say, okay, maybe ISPs will block sites. But hey, people will get mad about it!

Verge says: The FCC says the free market will take care of any restrictions ISP try to place on their service. As if the free market ever worked!

3. NN repeal will protect users' privacy

> On a really technical level, the FCC is correct here.

> The commission’s privacy rules were struck down by Congress earlier this year, so there aren’t any privacy rules in place at the moment. But that happened, in part at least, thanks to the current FCC chairman’s campaign against them. Had those rules been kept in place, consumers would have been covered by much stricter privacy protections than what the Federal Trade Commission will guarantee. That’s because the FTC mostly has privacy guidelines — not strict rules — whereas the FCC was able to define specific behaviors that are unacceptable. Without net neutrality, privacy enforcement will go back to the FTC’s broader approach.

Verge says: FCC is correct. But that won't prevent us from making up some bullshit!

4. NN is hurting broadband investments

> And if you only look at the numbers cable companies give you, that would appear to be true. If you take a broader view, it’s clear that broadband investment had already been declining before net neutrality was put in place. <link to https://www.vox.com/2014/5/12/5711082/big-cable-says-broadba...

Verge says: FCC is stupidly believing ISPs' own data. Here, take some data that proves them wrong. Oh btw this data is also provided by ISPs.

5. Broadband providers will charge you a premium if you want to reach certain online content.

> What the commission is arguing here is that, because something didn’t happen in the past, it therefore won’t happen in the future. But that’s not how anything works. And there’s a good argument to make that, because the FCC is explicitly giving ISPs the thumbs-up on this stuff, it’s more likely to happen than ever.

Verge says: The FCC is completely right. But fuck them for not supporting unneeded extra government regulation and oversight.
