To add some color to this, the culture for a very long time would reward folks that came up with novel solutions to problems or novel products. These folks would dedicate some effort into the implementation, land the thing, then secure a promo with no regard for the sustainability of the aforementioned solution. Once landed, attention goes elsewhere and the thing is left to languish.

This behavior has been observed publicly in the Kubernetes space where Google has contributed substantially.


Can you share some examples in the Kubernetes space? I'm not as familiar with that area.



Thanks!


> Ah. So what we have here is, regardless of whether you agree it's true or not, a political agenda masquerading as a personality test. It's purpose is to argue Peterson's vocal political belief that the gender pay gap is not an issue, because women are biologically better at being nurses instead of engineers. His proof? Just look at those Scandinavians, they have completely solved sexism (citation needed) and still see this gap

I'm not sure it's a political belief per se so much as a refutation of the implicit assumption that the gender pay gap is entirely the result of sexism and more likely the result of other factors, not least of which are the traits and proclivities of either sex.

I'm not prepared to debate whether or not his argument on the topic is legitimate, but it is something that he has elaborated on and supported with some data.


But what does that have to do with an online personality test?

You can make that argument without having it bleed into situations that are expected to be apolitical.


The H10 is the gold standard for HRMs and the one most commonly used by anyone doing experimentation with HRV. I don't have the specs memorized off hand, by my recollection is that it does a better job of capturing the entire waveform.


Yep that's right, and the H10 is able to stream the ECG waveform. For this project I used the inter-beat-interval that is sent however, as it means I don't have to run peak detection on the ECG to get heart rate.


To say nothing of the ethics of cheating, I think this behavior speaks to the value of the interview process. If it can be gamed so easily, it's likely not a great measure of the quality of the candidate and the companies that have implemented deserve the hires they make.

It'd doubtful the folks at the company actually mind that the interviews are being cheated. If the candidates appear to be qualified and appear to be fill the role for which they were hired and appear to be competent in that role, that's sufficient for most corporations and one of the problems working in "tech". That is to say, there are plenty of people in it that appear to be doing a thing, but aren't actually capable.

Somewhere in this thread a poster mentioned woodworking, which is a nice contrast. If you hire a carpenter, it becomes obvious pretty quickly if the carpenter is competent.


the problem is that its a zero-sum game, you can only compare performance across a cohort. if the majority of your cohort cheats, and cheating hurts performance, then they'll all be low performance and you'll still end up promoting some of them (because thats just what happens)


> you can only compare performance across a cohort

I can't accept this premise. Optimally the persons responsible for managing engineering staff should be able to independently determine whether the work being produced was of sufficient quality or not regardless of the cohort.

At issue here, I believe is that this is a difficult thing to cultivate consistently in many corporations and so there's some desire to create standardized metrics for performance against which a cohort is measured. Regardless, most large tech firms have some kind of well defined rubric against which the engineers are measured.


what do you mean sufficient? I think the premise is that all these people can get the job done, but some of them can do it better and faster. In the big tech scene its not about being sufficient, its about being the fastest (faster than the competitor)


> air source heat pumps have been getting a lot better

Mitsubishi, specifically, makes a heat pump with the marketing vernacular, "H2i" or "hyper heat" which has reasonable efficiency down to -13F/-25C.


That's not even the best one any more. Some other systems hit -30C.


The part with the compressor in it costs $12000-$15000 minimum just for the device, nevermind installation and the rest, and that's for an equivalent to 3-6 ton systems commonly installed.

My mini-split system worked fine down to about 10F, then it was defrosting for 10 minutes after every 8 minutes of use or so. I just turned on crypto miners on a few computers to supplement. Laptop crypto mining is useful if you want to keep your hands and wrists warm, hats, blankets, sweaters, and some old 100+ watt light bulbs will also help.

All this is to say "you can just get a -30 degree capable system" is out of reach for most people in the world. A large swath of people geographically close to my house still use window or wall HVAC units, rather than ducted systems. I was the only split ductless system my HVAC installer had ever installed - they had to come fix their install 4 times (four!) and eventually i contacted the asurion purchase protection people and got refunded for the cost of the HVAC system.

it works fine now, i told the HVAC installer to cut the threaded connectors off everything and sweat all the copper lines together, and it hasn't had an issue since.

it was always breaking in the late fall and early spring, where it had to heat at night but cool during the day, it would always break around 11AM. The pressure differentials must have been an afterthought in the design, i guess.


Here in Finland you can get a split system good for -30 Celsius for 2-3k€ including installation. Mitsubishi is considered the best, but others are available. My Panasonic has been working fine.


is that for a single head minisplit? In the US i installed one back in 2004 by myself, and i remember it costing around $1400.

the system i have now is also a minisplit, but it has 5 heads, and is 5.5 tons. If i run one of 4 heads by itself, it can do 3 tons to just that head. the fifth head is smaller BTU, i think it's 3/4 ton max. It cost $3,723.68, plus an additional $5000 to get it installed and working, give or take. As i mentioned, i got the $3723 refunded due to manufacturer's defect.


That's for single head, yes. From my point of view, single head is the norm here. In here too, I would imagine multi-head to be cheaper per head than single head.


I love it, but when it fails at scale, it can be hard to reason about. Or at least that was the case when I was using it a few years back. Still keen to try it again and see what's changed. I haven't run it since bluestore was released.


Yeah, I've been running a small Ceph cluster at home, and my only real issue with it is the relative scarcity of good conceptual documentation.

I personally learned about Ceph from a coworker and fellow distributed systems geek who's a big fan of the design. So I kind of absorbed a lot of the concepts before I ever actually started using it. There have been quite a few times where I look at a command or config parameter, and think, "oh, I know what that's probably doing under the hood"... but when I try to actually check that assumption, the documentation is missing, or sparse, or outdated, or I have to "read between the lines" of a bunch of different pages to understand what's really happening.


How is a DEI policy "left" or "right"?


I think one way to measure how far left or right by looking at how far they take "Equity". If equity is an anti-racist version of "racial equity" then it demands "anti-racist" discrimination. To quote Kendi

"The only remedy to racist discrimination is anti-racist discrimination. The only remedy to past discrimination is present discrimination. The only remedy to present discrimination is future discrimination."


It doesn’t have to be, but it has been made “left” in many companies. Start with seminars and zoom calls with progressive politicians as guests, donate company $$ to organizations that support civil rights while espousing Marxist beliefs, enable volunteer time to support certain types of politicians, etc.

And that’s all aside from the instances of forcing CRT training on the workforce - plenty of controversy there as well.

This stuff happens more than you’d think.


I have seen all your examples in a top tech firm. In that same firm any public questioning was quickly shouted down in a way that made it clear that your were putting your career at risk by asking why the company was promoting left leaning politics through DEI.


"Critical race theory" and "Marxism" are literally two different theories that oppose each other.


This is wrong. CRT is basically repackaged class war, and Marxism.

I was born and lived under communism, and a lot of the means CRT is peddled, feels eerily similar to communist/socialist propaganda and perpetual class warfare. Because you have to have some kind of eternal enemy in order to prop up the ideology, even if it is a failed/bankrupt one to the core.


> This is wrong. CRT is basically repackaged class war

You didn't disagree with me. By repackaging something it opposes it. That's called the narcissism of small differences - CRT is a liberal thing and nobody hates liberals more than leftists.

Anyway, you don't seem to be talking about critical race theory (something taught in graduate schools) but instead critical race theory (a collection of unrelated or made up things Fox News has decided to complain about this year.)


I believe the ideology went something like this

marxism -> neo marxism -> postmodernism -> critical theory -> critical race theory -> anti-racism

You can see the connections by swapping out class for oppressions/oppressed power dynamics plus intersectionality


The connections between most of these are just that different French people wrote about some of them at the same time. e.g. Marxism and postmodernism are also opposed to each other.

Corporate trainings of course also don't contain hardcore theories, because the point is to be inoffensive and prevent lawsuits. Ibram Kendi or Robin DiAngelo might show up and do a talk (these people also don't exactly agree) but the actual result is that people are going to start saying "allowlist" instead of "whitelist".

What CRT actually says is that since many US laws were written under racism, those laws still do racist things, and it's obviously true: https://twitter.com/AdamHSays/status/1394986418993340425


What CRT/anti-racism actually says is:

capitalism is racist

the US is systemically racist

all white people are racist

color-blindness is racist

all disparate outcomes can be explained by racism

None of the analysis is falsifiable so it is closer to religion than anything else. Based on the above lens these ideologies deconstruct things like laws and structures, or science and this is how you end up with racist math, racist knitting, racist birds... racist everything.


The more extreme ideologies of DEI like critical race theory are closely associated with (in American terms) "the liberal left".


> The more extreme ideologies of DEI like critical race theory are closely associated with (in American terms) "the liberal left".

“Critical race theory” isn’t either extreme or an ideology, its a fairly mainstream historiographic approach (it was a novel, but not particularly extreme, idea in its field nearly half a century ago, but now its not even that) that the American Right has recently adopted public opposition to (especially, oddly enough, in places it isn’t being promoted) as a tribal identity symbol (alongside election conspiracy theories and defiance of COVID precautions.)

EDIT: It’s particularly odd to call “critical race theory” as an “extreme ideology of DEI” since DEI existing at all as a thing is based on a mainstream understanding of reality developed through critical race theory.


They've adopted public opposition to the words "critical race theory" and have essentially just made up a definition of what that is, or rather not defined it at all[1].

The level of discourse they're at doesn't admit discussing actual grad school critical theories, it's just a chance to bring back older school curriculums like that we didn't do anything bad to the Indians, the Civil War wasn't about slavery, MLK had a point but we've done all he asked for, etc.

"DEI existing at all as a thing is based on a mainstream understanding of reality developed through critical race theory."

This strikes me as a very postmodern and intersectionalist view. My reply pointing out the ideological progression as:

marxism -> neo marxism -> postmodernism -> critical theory -> critical race theory -> anti-racism

was downvoted. Your post seems to validate it though.


> This strikes me as a very postmodern and intersectionalist view.

There's nothing “postmodern or intersectionalist” about noting the historical factual sequence:

critical race theory (1970s+) -> detailed analysis of post-civil-rights structural/institutional barriers to racial progress -> modern DEI


The idea that you can understand reality through CRT was what struck me postmodern/intersectionalist not the historical sequence. "lived experience" as truth and all that.


CRT, like critical theory more generally, has both modernist and postmodernist branches (contrary to the Right’s typical propaganda, which tends, confusingly, to associate it vert tightly with postmodernism despite also associating it very tightly with Marxism, which is extremely modernist.)

I suppose your comment would make some distant sense if only the postmodernist branch of CRT existed.


Curious how large a dataset you're using?


Under 100GB; I'm sure vanilla Postgres would suit our needs too. However, adding TimescaleDB on top was not much of an investment and in exchange we got an interface for operations we do often, effortless continuous aggregation, near-constant time appends, and a native way to leave data mutable for a period of time before marking it immutable and compressing it.

The performance is a great feature but its also just an intuitive, familiar (pretty much just SQL) tool that makes life easier.


Cool. I'm keen to try it. Wondering how well it works with multi-terabyte data sets.


The content of this discussion does an excellent job of explaining the reasoning of the people that have downvoted this comment.


How does interacting with reps have anything to do with "onboarding"? This is more or less an evaluation of how easy it is to take advantage of credits.

I'd be more interested in how easy it is to use a credit card and get a service off the ground. What is the relative quality of the products on offer by either vendor?
