This is a perfect example of unseen/unknown/inaccessible backdoors for most (non-)immigrants in the U.S. The (apparent) complete opacity of USCIS when it comes to delays like this can be devastating. I know several people who had job offers rescinded in late 2018 because their H-1B RFEs or approvals arrived way past October and they had been waiting nearly a year or more for adjudication after making it through the lottery.

Thank you for sharing this tip, still it's so infuriating.

the same as the other method proposed.

agree, but this does not make it illegal to pay, it just forces the ransom to be delayed so that the police can investigate. If the family manages to get money in another way then they can choose to pay.
This is actually an exception that GDPR makes for storing data - companies can keep around some sort of record to "tombstone" users.

Sort of. GDPR is so woefully under-specified in some places, and general in others, it's really entirely up to the will of the regulators what would count as a violation.
Hi Peter,

I'm a Canadian permanent resident (Australian citizen/passport) I have a valid B1/B2 visa which allows me into the US for 6 months at a time, but obviously no work permitted. I have questions about what constitutes "work" and I don't want to break the rules.

1. I have published some books, and have hard copies of them I bought. Am I allowed to physically sell those (for profit) while I'm in the US?

2. If I give talks in public venues (community halls, etc.), can I charge admission for porfit? What about "admission by donation?"

Thanks very much!
Yes, you can use Cantor's diagonal argument to enumerate all triples. No, it does not answer the question whether every integer can be written as the sum of three cubes; it only would if the set of integers was finite.
> I never truly understand issues people have with these things. I tune my notifications as to avoid true interruptions and filter most false positives by quick looking.

You've answered your own question. The product is distracting by default.

The savvy user can cut down on the distractions by configuring notifications, teaching themselves how to scan messages, etc., but if there's one thing we know from 70 years of writing software it's that most users accept whatever defaults you give them. Sometimes that's because they don't know they can reconfigure the software; sometimes it's because they do know they can reconfigure it, but can't figure out how; sometimes it's because they know how to reconfigure it, but are too busy with other things to do so. But the underlying reason doesn't really matter, what matters is the general effect: the default experience the software provides is the experience that most users are going to have with it. And with Slack, the default experience is distracting.

> Even then, come on, I cannot believe experience hasn’t taught most of you how to handle quick interruptions.

How many threads have been posted on HN complaining about things that take programmers out of their state of "flow"? How many programmers have you met who are happy to hear their phone ring when they're working?

> There are true interruptions like constant notifications, people physically talking to you about other things, and stuff, that while you cannot really tune them all out, you should be able to handle better with 2-3 years of experience.

2-3 years studded with bouts of lost productivity is a lot of lost productivity. A product that tells me my life is "only" going to suck for 2-3 years while I learn how to use it is not a product I am going to be thrilled to use.

You might be interested in the hide-and-seek variant Sardines. One person hides, with a group of seekers. Seekers that find the one who hides have to hide with them, until one seeker is left. There is nothing like the feeling of looking around, encountering fewer and fewer other seekers, until you are alone with the knowledge that you just lost.
some good comments and thoughts in here.

the Slack status feature you mentioned is -- sadly -- most often used by Slack users to add a cute emoji or whatnot. this is unfortunate.

Slack administrators can set suggested or "default" statuses. it's at https://<yourslack>.slack.com/customize/statuses

and so, a company can set statuses that staff can be required to pick from, perhaps some common ones like:

- In the office
- Working from home
- In a meeting
- PTO

and the company can then make it known to staff that their status icon should accurately reflect their current work ... status, and not whatever cute emoji they want to use.

DND/Do Not Disturb should not affect use of Slack status. Force the notification through if your message is urgent.

this is not rocket science.

if Slack usage is affecting how a company works because staff can't tell if someone will respond or not -- change the way the staff use Slack to better suit the business.

This is my biggest IM pet peeve. When someone separates their "hello" from their actual question, my attention is broken for 30 seconds to 5 minutes for absolutely no reason whatsoever until they send it.
Not necessarily every dev box, but I'd say that in most environments it's reasonable that devs would have full permissions in any "their" dev boxes/VMs. If you split boxes/VMs across devs instead of sharing them, then the access would be limited to whatever people are assigned to own that box, but they'd have full access. I mean, if something breaks, it should be trivial to reset that machine or get a new one, VMs can be cloned and spawned in seconds and there's no reason not to spend an hour once so that you automatically get a fully working dev environment with all the tooling needed.

In any case the notion of "the root password" seems weird, root passwords should be unique (even for VMs), randomly generated, and mostly not used; in most situations you'd use publickey authentication instead of passwords.

>Instagram could be considered a defensive acquisition. They should argue that the motive behind the acquisition was to expand their presence into mobile/imagery, which is different than defending social networking.

I mean there's going to be discovery and depositions so "arguing" an after-the-fact justification is kind of pointless.

Also New York Post already reported that the FTC had documents suggesting the Instagram purchase was to take out a competitor.

>At the center of arguments to block the deal — made by then-FTC Chairman Jon Leibowitz — was a document the FTC had uncovered by a high-ranking Facebook executive who said the reason the company was buying Instagram was to eliminate a potential competitor, sources said.

“It was a spectacular document,” one source close to the situation said, declining to say whether Facebook CEO Mark Zuckerberg himself had written it.

Many questions about the integers are recursively enumerable (like: what are the counterexamples to Fermat's last theorem?), but this doesn't really reveal anything about any deeper structure. Part of the conjecture is, indeed, that the set of numbers that are a sum of three cubes is recursive, which is given by a simple condition on the residue modulo 9 (see a sibling comment). However, mathematicians don't usually think about recursiveness of sets when they think about whether a problem has been "solved." It's more about whether some structure has been satisfyingly illuminated (maybe, to make something completely up, triples of numbers whose cubes sum to a particular number are found to be in one-to-one correspondence with "tripolar Hopfian unital schemes," and if something is known about them this might be satisfying). Of course, knowing whether or not a set has a recursive description is nice, too.

Here's something I've wondered about. In knot theory, a "knot" is a closed loop of string in 3d space, and if you allow the string to pass through itself it can obviously be unknotted (put into a form where it is a closed loop flat on a table). An unknotting is a sequence of pass-throughs to unknot it, and the unknotting number is the minimal number of pass-throughs among all unknottings. Unknotting sequences are actually recursively enumerable, but it's unknown whether there is a finite-time algorithm to compute unknotting number!
It would be better for some (more reasonable rents, no need to own a car) but worse for others (retirees who intended to sell their house for millions and move out to the country). It would also force the city to invest in more mass transit, which will inconvenience a lot of car owners.

The regulations have the effect of picking winners and losers, and since the regulations were written by the old established homeowners they were the ultimate winners. If young people and renters want to see change in their lifetime they need to start getting themselves elected to local boards and councils. Local politics matter.

I actually fully understand this situation. If you build stuff you want to reduce communication channels and keep it lean, otherwise you get a lot of distraction about mostly superficial and insubstantial matters. Important things will happen there too, of course, but you prefer to have a controlled ways of communication (e.g. something that works in your team). Sometimes it’s good to shorten some communication paths and directly reach relevant people. But in the longer term you want to avoid it. Otherwise you will have your devs being contacted from other different people and it will create a lot of communication mess. You want to secure your people from such noisy communication.
Not really-really (JFYI).

Those are not properly "shutters", they are (as you say) "tapparelle" (which translates back to "rolling shutters" or "roller shutters"), they are relatively "modern" and they have been used for yers mainly as a low cost solution to the traditional windows "sets".

They were only widely adopted in Italy after WWII in new buildings.

They were actually available in Italy - and of course in wood only - since the '20's but not widely used, actually intially they were considered "trendy" and used by "name" architects/designers in luxury or public buildings (example):

https://en.wikipedia.org/wiki/Casa_del_Fascio_(Como)

, whilst later they became synonym with "poor/economic buildings".

They are not "typically italian", as they are common also in other EU countries and were most probably actually invented in France:

https://www.griesser.fr/en/products/rolling-shutters/

A famous example of their (early) use is Casa Milà in Barcelona (Spain) by Gaudì:

https://en.wikipedia.org/wiki/Casa_Mil%C3%A0

Interestingly our UK friends seemingly call them "continental" (another example):

https://www.ukrollershutters.com/product-category/continenta...

Traditionally in Italy (but it depends on the area/region) we have "persiane" (on the exterior), that can give some shade from the sun while allowing the air to pass, like these (example):

http://www.bglegno.it/linee-serramenti/persiane-legno/

Then the actual window (with glass panes) and finally the actual shutters, which are called "scuri" (or "scuretti"), like these (example):

http://www.bglegno.it/linee-serramenti/scuretti-in-legno/

They are internal and completely darken the room if closed.

What the owners want (in terms of $ for their house) impacts the supply of houses, which impacts the price of houses. It is further impacted by city councils restricting building new housing (city council is composed of home owners) who have an incentive to raise the value of their house to what they want.

TL;DR we can stretch a really long piece of fishing line from the Moon's surface to geostationary orbit. And we can probably send payloads to the moon by docking with said cable in geostationary orbit too. The funny thing is I literally mean fishing line here, they call for using a constant cross section cable made of zylon or dyneema with a diameter of about 0.35 mm. At least initially. Both dyneema and zylon with this about this diameter are sold as fishing line. Initial payload to/from moon seems a bit low as the line at the Moon end can only support 100 kg. The dynamics of such a thin, flexible cable which passes through an unstable(!!!) lagrange point should be interesting. We know that very long space tethers can behave in weird ways[0]. This idea is crazy and attractive enough that it warrants further investigation to at the least find out what the problems are so other people don't make the same mistake.

> ”Where are you such that it's attractive and that you already use a 4G router?”

London, UK. I pay £20/month (~ USD $25) for SIM-only, unlimited data wireless broadband on the Three network. 12 month contract, though you can pay a bit more for 30-day. Got a Huawei MiFi router (tiny credit-card size thing) on Amazon for £69.

Typically gets around 40 Mbps, sometimes a bit less at peak times. But I think the speed is limited by the cheap router as I’ve seen up to 105 Mbps if I put the SIM in my iPhone!
I agree w/ the parts that we aren't belief-less heathens. I'm still inspired and awestruck as an exmormon/agnostic when I see a beautiful space image or sunset. Or just watching my kids experience new things for the first time.

I find I'm more spiritual as an agnostic than I was before losing religion, spiritual to me is just feeling inspired or 'touched' by a movie or book or event in my life. It's about honoring the small parts of life because we don't know what comes after.

I still believe an afterlife could exist, but it isn't controlled by a deity, it'd just be energy being re-used which happens all the time in nature.
