The big issue is what happens to the refrigeration gases at end-of-life because they have such high global warming potential. The units are nominally hermetic, so they should last their entire life without leaking much refrigerant. If you have an old AC unit, try to dispose of it responsibly by not sending it to a landfill. A responsible recycler/disposal facility will reclaim the refrigeration gases for recycling or disposal.

There really aren't good alternatives available for purchase right now. Almost all units sold today will contain gases which have low Ozone Depletion Potential but still have high Global Warming Potential (~2000-9000x as potent as CO2).

There is a heat pump hot water heater available from Sanden using CO2 (ironically) as a refrigerant, which has a GWP of 1. It is pretty darn expensive.

This whole area is really a place we need some startup innovation. Both products that use something other than HFCs for refrigeration and some kind of business model or non-profit which will have the goal of getting old units out of the hands of consumers responsibly.

Retrospectives are great if they actually lead to change. Unfortunately that’s often not the case. The same issues keep coming up repeatedly and soon the retrospective is just another chore.

I would love to see retrospectives where managers one or two levels up attend (usually it’s just the devs), listen to issues and address things that need support from a larger point of view. Agile theoretically should transform whole organizations that way.
I have no evidence of this, but it sadly (probably) makes sense to apply a paywall after N referrals from a particular domain, or even after X traffic over Y time as a social trick for getting people's peers to subscribe

This is an American dream-esque article about a boy and a domain name. They meet, he wins the auction, and they start spending time together. The domain name, she calls to him and eventually they hook up with an industry group and bring onions to the world.
While on the face of it, this may not seem like the best business plan - I actually really like it. He found something personal (domain knowledge from his home state industry), something with a good customer need, and filled a niche of better customer service and process. Here, everyone wins... So I guess it is also an 'invisible hand of the free market' dream too.
So when you have a kid, and your woman takes maternity leave, let me know how 'free' it was for you to work and provide for the entire family.

Maybe Bernie can give you all that for free and you won't feel that 'life tax'.

Also, since media at large wants you to believe you make more than a woman, you're getting a higher 'life tax' each pay period.

I mean, cool effort and all, but you don't need to pin a martyr banner on your back, hero.

Small point of correction: r-152a is an eco-friendly refrigerant. The article incorrectly groups all liquid refrigerants together. R12 [and R-134a somewhat] deserves it's reputation, but that has been out of use in America/Europe for a long time. It's worth to note in China/India, researchers suspect that R12 is still in use despite regulations against it.
I think you can do it by tracking caches pulled in during speculation and dumping them if speculation failed. Perhaps on a new barrier instruction that's lighter weight than lfence (as you're just enabling a recording mode for cache snooping).

Ultimately I don't think many speculative instructions actually pull in cache lines, so we can either clean up when they do, or stop speculating when a line would need to be loaded.

Ask YC: Understanding how to do the best movie recommendation
There’s a billion lists and recommendation tools out there, but we realized that the movie we end up liking the best were always the ones recommended by our friends and family. They aren’t always available on Friday nights, so we thought, how about all the other friendly faces out there? How can we connect to them?

We would love if you could take a few minutes of your time and help us discover those insights by answering questions:

1. How do you get your movie recommendations?

2. How do you ask for a movie recommendation? Do you ask for a genre, actor, or something completely different?

3. Do you help people find a movie to watch when they ask?

4. How do you recommend a movie when asked?

5. How satisfied are you with the automated movie recommendations that Netflix, HBO and other online services give you?

6. If there was an app for it, would you like to become part of a community asking for and giving movie recommendations?

7. Would you like to be a part of our journey to create the best movie community then leave your email address here.

Thanks
I don't think that's fair; it's certainly not specific, but it is a way to structure society. It's just a vague way to do it. It establishes a base minimum for what to expect from people, and what to give to people.

As for the systems associated with it, I think it's an oversimplification to say they do not work. As I mentioned, there is a not-insignificant number of people out there who long for a return to life under Soviet control (just from people I've met in my travels). To them, it worked. It wasn't perfect, but I didn't say that and nothing is. To a great degree, history is written by the victors, anyway.

Rather than play on red scare feels, I'd appreciate engaging with the idea, and again I ask: what's better than that, and what about that don't you like?

I'll even posit an alternative: personal freedom is the most important thing, even if it means people's needs aren't met.

I don't agree, because the world is resource-rich enough to ensure everyone's needs are met, so where do you draw the line? who do we say it's okay for their needs not to be met? rather than defer to an amorphous "market," I'd like to hear from you whose needs should not be met.

> Then you're not disagreeing with me, because those functions pass my test as I demonstrated above.

Yeah. I must have misunderstood your definition of ‘obvious’—I though you meant ‘an obvious inclusion to the standard library’, not ‘having an obvious definition’. The definition is obvious, why they should be in a standard library is not.

> […] since by your own admission you don't even know what they are

I mostly do—I studied mathematics. Or, to be more precise, I learned about them, then never used them in programming, had to remind myself what they were and even after that, I don’t find them useful enough to warrant an inclusion to the standard library. Thus, since they were included, I think that’s a good evidence of C++ committee not trying to keep its standard library concise.

> You named some other features, such as quaternions, that you think would be better for implementors to spend their time on, but surely you can imagine someone like yourself who is tired of having to define the Bessel functions every time they start a new project, and can't imagine why the C++ committee saw fit to include something so useless and obscure as quaternions before getting to Bessel functions.

The thing is, I can’t. If you use them, you want a better support for solving differential equations than C++ offers anyway, so it’s more of a ‘OK, I have this small part already implemented, but I still have to find ways of doing the rest 95%’. This, plus the fact that I’m quite certain that people using C++ to do 3D geometry outnumber people using it for solving differential equations by a few orders of magnitude—a cursory glance at GitHub showed me that the only projects in C++ that mention it are… implementations of a standard library (and forks upon forks of those).

My problems with this is that C++ is now in a very strange place—it implements some very high level, niche features, bloating the language and its implementations (the size of glibc is a practical problem) while still lacking many others, that seem much more ‘obvious’ (i.e. ‘if given an unknown language, I would be much less surprised to find them included in its standard library). In the end, I have a language that both has annoyingly big standard library and heavily relies on other, non-standard ones for quite a lot of things.
Anyone else read the subject as Toronto has a lot of haunted hotels?
Lots of others are confused about this project. I've never seen it before, but I think I get the idea behind it.

We have all this information we can learn from, but literally not enough time. Just think of all the articles you might have "to read" or books/papers/etc. of a similar status. Our best bet is to record our thoughts on the things which seemed to be important and come back to it later if it becomes more relevant.

If you had a Kindle book and you invest a ton of time using the highlighting, notes, and flashcard features of Amazon's app then all that data is stuck there. There exists a website to take them out and from the app you can "export" the notes, but it clearly feels forced.

You could simply write down your notes in another app, or in a notebook, but then you lose the whole purpose of why eBooks might be super interesting here (namely, that you might miss a part and you can simply click to view the original material).

A paper book, unless OCR'd, can't be searched and endlessly marked up the way an eBook could in theory, although it certainly does allow you to completely own the information and work you put in to understanding the topics.

In a sense this is trying to solve these smaller problems which make the original idea of collecting and annotating the information you find on the internet and elsewhere difficult and hard to maintain over any reasonable timeframe except as very simple document formats (e.g. HTML, Org, or Text files)
I've worked at a place where all that IS often the case: retrospectives surface issues, those issues typically get resolved, managers attend, etc.

Even at one point when we felt like retrospectives were getting less effective we actually retro'd that and made a bunch of changes to the process (namely, checking in a set number of weeks after each retro to follow-up and see whether action items were indeed followed through on)
> In 99% of programming languages, infix operations are only used for arithmetic

I've been spoiled by Scala, but certainly most languages allow a "subject.verb(object)" style for general-purpose code, and that reads a lot better (particularly for those looking from the business domain) than "(verb subject object)".

> It even supports symbols like "√", unlike any other language I can think of!

Heh, again I'm spoiled by Scala, where √ is just another method/operator (there's no distinction) name if you want it to be.

It must be nice for Kent to just trot off and investigate whether or not his work "matters". For the rest of us, this is a non starter because that effort can't be captured in a story or a task attached to a story on the Jira board.

For us dark matter engineers we need to tell ourselves that, because we're paid, our work "matters".

Am I the only one who just does not care? I mean, there are so many 0day vulnerabilities... and most of the really useful ones are not even shared publicly.

I just don't believe that Spectre represents any kind of "above standard" vulnerability to the computers of regular people (and even most IT professionals)... I understand the concern if we're talking about internet-facing network services/servers, but forcing these performance degrading "fixes" on people with Windows and stuff... is a massive overreaction. All these patches should be opt-in.

Note, they talk about retrofitting mitigations into the web browser running javascript, not in general. It's hard to find a reason why software mitigations wouldn't work for a language and a compiler designed from scratch for it.
The hardware mitigation at this point is disabling some of the advanced indirect branch prediction in some circumstances (I don't remember the exact set of circumstances). It is nowhere close to disabling all speculative execution.

It's very common for folks to try to turn their hobbies into a job, only to have that realization too late. I feel fortunate to have had that realization before considering it.

> Sometimes I wish I did not put it out there.

You can always take it down or disable issues[1].

> Though if you accept donations for it, then you have an obligation to keep it going.

You most certainly do not. In the same place you ask for donations, make it clear they’re for people to thank you for the work you already put into it, not to “buy” future work time.

If you don’t want to work on a feature, say “no”. If a user acts entitled, explain (tip: keep a non-confrontational text snippet ready) that you’ve developed the software in your free time and are under no obligation to fix other people’s bugs; when you do, it’s because you want to. Lock the thread if need be. Does the user come back to open another issue, guns blazing? Block them.

I spend hours every day on open-source. I’ve learnt that most users are reasonable and can take a “no” if you add a “because”. It does not have to be the soul-wrenching experience many maintainers make it out to be.

I'm not sure if this is an Instapaper clone, an Evernote clone, an rss reader, or a flash card sync system. Not really sure anyone needs this.

You talk about walled gardens and privacy concerns and "rebooting" the web but say that you're using Google's firebase as a backend for sync. Personally, I'm just sort of at peace with the fact that Google has a copy of all my email and records of my location for the years I've had an android phone. But let's be super real - Google products and privacy aren't known for going together.
