Since the title is linkbait-y, I'll share that after reading it, I think the article boils down to these two quotes:

"The bottom line is that although there are holes in our knowledge, there is no concrete evidence of any chemical risks of sunscreen at typical doses."

"In the case of melanoma, the more dangerous form of skin cancer, there’s no data that tells us whether sunscreen works."
What is interesting is that backblaze still use the 45 drive in 4u config.

We use Dell/LSI/Netapp/engenio md3260s which pack 60 drives into the same space. We use raid 6, as we want the storage to manage the redundancy, not the software. With four hot spares we achieve a density of 170 tb usable per 4u (technically its 5U as we have a fileserver sitting on top. however assuming 48u it works out the same density)

With backblaze, assuming raid 6(unless you are using FEC then there is no other way.) you'll only get 120TB per 4u (but a file server as well)

The big advantage of the Dell/netapp/etc raid is that the drives are easily hot swappable. Ironically at the scale that backblaze are doing it, they are probably cheaper as well.
And no one has yet mentioned rickets!

Once virtually eliminated, rickets has increased markedly, in some studies as much as five-fold. In the malls I now occasionally see children who obviously have rickets. Unless corrected early, the adult will bear the scars of the child.

Also there is mention that ingestion of vitamin D is superior to sun exposure but AFAIK there is no evidence of that. The ingestive route has it's own problems.
Cool, and in the spirit of Show HN.

I wonder if the power savings going from 4TB -> 6TB could make up for the difference/GB.

Spinning disks still operate at relatively high power (~8W), and I don't think this value would change with capacity (they don't add extra disk heads, I think its just more platters/higher capacity platters).

Pretty much the major cost running servers nowadays is simply the cost of the necessary electricity to run them and the cooling systems.

(Note that this doesn't apply for Backblazes usecase; they fill harddisks up, then pretty much power them down. That is why you can't instantly access your data stored with them)
Did people stop needed ARM chips? Intel can't make their own ARM and beat others with superior fab tech?
Anyone know why they use two layers of pgbouncer? The speaker mentions this briefly in the Q&A but doesn't go into detail.
I was looking into the peers seeding the torrent. There I found a host langley.fr seeding. That is how I got to the article.
I am almost sure that the reasoning for the redirect script was something like this: since they have ads on that "parking" page, whoever tries to access the server, should see the ads. That's probably why they have this terrible redirection script in place. Which still keeps the original question "who would do that", because this is terrible.

The TTL value has no direct connection to the parking page. It's probably by the coincidence that DNS record had a high TTL and pointed to that IP address. But no one can be sure here, because there is always a posibility that DNS was hacked, although the DNS hosting provider sais that DNS error was not a result of a hack.
To add to that PS2 had a longer lifespan than the X Box which allowed companies to reuse exiting code for longer. Unfortunately most AAA games are cross platform making targeting the lowest common denominator which limits the value of unusual hardware.

PS: Xbox was released over a year after the PS2 yet MS released ther next console before Sony.
It seems equally likely age isn't included because widespread discrimination based on age hasn't been a historical norm (and arguably isn't now) the way discrimination based on race, ethnicity, religion etc. has. One "high level google employee" declining to answer such a loaded question in a social/unofficial context is definitely not a strong indictment of their culture.

There could be something to this (younger workers don't have families, work longer, cheaper, fresher skills, to rehash some common points), but this article feels really contrived.
But that would probably open them up to a lot of users using their service for online storage instead of just backups which they are trying to avoid I believe.
Couldn't you save a ton of money by explicitly moving old data to 'cold storage,' and keeping it on Glacier? Users would probably understand if data older than a year takes a few minutes to be retrieved.
I speak I think for many people on HN when I say that at least on this thread, in this context, in this discussion, in these circumstances, this idea should be dismissed out of hand.

Let's stipulate you just want to have an interesting intellectual conversation. Can we have it some other time?
Computer Coding Setup From The Matrix
It's worth remembering that many other industries have the opposite problem. Lots of the best jobs being occupied by baby boomers who are taking longer to retire, leading to a lack of opportunity for younger people to get on the ladder.

So we have a large number of smart younger people who are underemployed, are google etc simply innovating by exploiting this undertapped talent pool?
When they say Siri is “partnered” with different companies, does that mean that it can draw from and direct to the companies' services/menus/store catalogs? Does that exclude smaller companies that are not yet able to afford a partnership, thereby bypassing them when making recommendations to the user?
S3's number is just marketing. It's going to be that durable until a black swan event wipes out 0.1% of all files. I imagine they keep multiple copies of every file, spread across multiple data centers. It's durable against hardware failure of all varieties, but it's still vulnerable to a software bug. It's also possibly vulnerable to certain types of natural disasters.

IIRC backblaze employs a similar strategy. They have the advantage that your home computer is still storing a copy, so even if they have a minor catastrophe they can recover by simply having their client re-upload those files.
I guess I'm not as easily impressed as you are.

Sam Altman recently wrote[1], "Yes, it’s awful to hear the horror stories of wildly inappropriate behavior from investors to the entrepreneurs pitching them. (Unfortunately, stories like these are not super rare, but because there’s a big cost to going public with them, most never get told. My hope is that YC has enough leverage at this point to make it clear that this is unacceptable and we will not continue to work with investors who do it.)"

Today, Jessica Livingston writes, "Nearly all the investors we know are completely upstanding and professional, but even one inappropriate incident is too many."

Sam's statement implies that this behavior is more common than most folks would like to believe, and that Y Combinator is prepared to punish investors who engage in it. Jessica's statement subtly suggests that this behavior is less common, and that the vast majority of the investors Y Combinator works with are above engaging in it.

Which one is it?

YC founders often do YC more than once. If you choose to pass on funding and date a founder, what happens when you they do their second lap?

What if you choose not to invest, date a founder, and then start to consider funding another startup that is in the same cohort and close to the founder you are dating? There could be questions about what information you have that you shouldn't.

It's a full-stop "don't do it." There's too much potential to hurt and divide the community and lots of smart, attractive people outside of YC.
There is very little information prior to signing up about what it is, what types of tasks they might be, and how much you might get paid.

Too much of a mystery to proceed further.

Nice CTA I guess.
Both objects are traveling at 17,000 MPH and any mistake could kill lots of people and destroy a hundred billion dollar structure and would set humanity back decades in space.

"Slow" in space is relative and extremely necessary.
Sadly, I sometimes worry that explicit moves like this deter investors from working with female founders. If the risk is, "I have to watch every little thing I say/joke with a female founder lest I get blacklisted", if I was a VC, I might choose to avoid female founders altogether. Wonder if the better solution involves more carrot and less stick.
I'm the author of the parent. I didn't claim that.
Actually no. We just wanted a cool name that was related to cryptocurrencies, but not necessarily had bitcoin or coin in it.
And conversely, I've worked on teams where most of the developers were "inexperienced" and didn't have the skills necessary to do a good job.

No one is worried about a bias against "bad" developers. The problem is that the same companies that are crying the most about a lack of available developers are (potentially) explicitly not hiring older developers. The cynical amongst us assume this is another tactic to keep employee costs down.

That's all I needed to read.
This brings back memories of working with PS2 dev boxes and reading Ars Technica. Back then it was a such a good source for this sort of information.

The PS2 was an incredible pain to develop for. Sony new it would be a hit no matter what they did. They really wanted it to have unique hardware. I also think they wanted it to be a machine that developers couldn't master in a singel development cycle. The way they released information about the VMUs later I think leads credence to the idea that they wanted the second and third life cycle of the device to show successive graphic improvements.
The Google homepage is only about 20000 bytes... if we assume an maximum segment size of ~1400 bytes, then 14 or 15 packets is about right.

I wouldn't be surprised if Google is sending the packets all at once and ignoring the ACKs altogether.

Heck, there's even a 2010 paper from Google on the subject of sending a bunch of packets at the beginning of the connection: An Argument for Increasing TCP's Initial Congestion Window[0]

Huh? Both statements can obviously be true.
Where are the photos of the connector?
It may be intended that way but it's not semantically appropriate. I noted the same ambiguity as the grandparent poster immediately and found it somewhat confusing given the 'zero tolerance' clause that immediately preceded it. Every definition of the word 'inappropriate' relates to specific contexts. Using it as a universal is simply wrong, however common it might be in some circles.
Your concerns are well founded, but for point to point, especially combined with any identity fingerprinting (public keys, etc..) would have none of these problems.

If your network is going to broadcast though to many recipients, shaming is about the only way to reduce this. Making sure the sender is who they say they are is very important as well (like it is with email), but I wouldn't suggest it would be successful in making it go away.

Once you start identifying senders explicitly, then circles of nodes can be established that can limit entrance and or ostracise people who are annoying. You have to attach cost to messaging in order to senders to value their message, and other than charging a real amount of money which is probably not a good idea, cultural and social costs are very important in establishing trust and getting people to think more when they send.

Fortunately humans have been doing this for 1000's of years, so if you put all the pieces there, it should work fairly naturally.
My first thought was "it'll be slow as shit", then I clicked the article to confirm. Win!
>it irreversibly changes the previously professional relationship in a very discomforting way.

This is very true.
That was exactly my thought so there is no "lucky" after all. At least not for sure.
I'm a Backblaze user, became one right after another post from their blog hit HN front page about 8 months ago. Backblaze almost saved me once when my external HDD died due to dropping—the reason it didn't actually save me is because initial backup wasn't yet completed (not their fault). Otherwise I could easily order from them a new HDD with restored data, which is a very nice feature.

Sadly their OS X client is kind of quirky—I'd rather have a command-line one that required hand-editing configuration files (I'd wish for something other than XML though), but which would run more reliably and transparently.

(Currently it shows “Computer Missing” and says that I haven't backed up in more than 2 weeks, though I did actually press Backup Now quite a few times in past few days. There're some other oddities in behavior. I suspect I'm back into “searching for decent online backup solution” mode lately…)
You think YC won't notice that, or will continue working with investors that studiously avoid investing in women?
It is known that cyclic aromatic compounds (like sterols) can pass through the cell membrane layer. It is also known that cyclic aromatic compounds can bind DNA (this is how steroid hormones work). It is also known that DNA breakage can occur when ionizing radiation strikes alkylating agents intercalcated with the DNA backbone.

Honestly, it wouldn't surprise me if sunscreen has sterol-derived compounds that in the presence of ionizing radiation could cause skin damage. We hear about this stuff all the time in things like cigarette smoke, charred meat, etc. etc.

That being said, the article doesn't address the incidence of cancer caused by NOT using sunscreen. Similarly, not all vaccinations are not 100% safe, but the risk you take from not having the vaccination is far greater if you didn't take it. Therefore, people will get scared off from using sunscreen from articles like this, likely increasing the incidence of skin cancer.
This is exactly the sort of issue that's supposed to be eliminated by DNSSEC validation.

The registrar's database gets corrupted? They are not hosting my DS records, anyway. That's in the top-level domain. You will be the least of anybody's worries if the top-level domain dies. And as long as the DS record is live, a validating nameserver can tell that the faulty DNS server is sending incorrect resource records, and should be disregarded.

Side note: My DNS server is a hidden master, that publishes zones via secondary servers, run by separate companies.

The corruption would still be disruptive, but it would not be such a disaster.
Agree, and I noticed it as well. It is weird because sometimes these changes are so obviously dumb.

this is in fact exactly how honeyd works: http://www.honeyd.org/
The reason melanoma incidence is increasing is because of a "diagnostic drift," similar to what we see in the rise of psychological disorders: http://www.ncbi.nlm.nih.gov/pubmed/19519827

We are more routinely getting skin lesion check ups and dermatologists and oncologists are more and more cautious, leading to an ever-increasing incidence of stage I melanoma. However, we're not really seeing an increase in later stage melanoma, meaning that the "true" incidence of melanoma is not increasing.

It's sort of a huge public health scam. The dermatologists are using this vanity metric of increased diagnoses as evidence that we're in the middle of a melanoma/skin-cancer epidemic, when it's simply not the case. Not that safe sun exposure practices shouldn't be promoted, but the motor behind these messages is a bit of a scam.

It's not Python that's slow, but scapy, which is dog slow. In fact, it is so slow that it should come
with big WARNINGs that it's only really meant for interactive use. Do the dissection yourself or use something built for that purpose.

It's really surprising to me that lots of ppl are using
scapy for things that require performance but then again
if you look at the scapy website or the docs, it's not immediately apparent that their tool is not meant for this.
Which I guess says a lot about the scapy developers rather
than the scapy users.

tl;dr Scapy is a joke, performance-wise.
Just to add, as someone points out below - What I'm suggesting above doesn't belong on HAM channels, even though it's not encryption. Emergency networks need to be free to use.

How much of the "ageism" is actual discrimination and how much is "we have a small budget and need 80 hour weeks" that older workers won't accept?

I received an offer from a very interesting startup in southern California (down between LA and San Diego, not SF). The offer was $30K/year (with increases as revenue increased), with minimum 80 hours a week expected. As cool as the projects were... There's no way I at my current age and life situation could possibly make that work. Ten years ago? Maybe. Fifteen years ago? You bet!
GREAT FIND! Very interesting read. I liked the parts about how lack of concern for pedestrians in the system is a legacy issue. Also interesting is the segment on stop bars for high speed stops. I never considered that the light stays yellow extra long to let cars clear! I've always thought "Good choice Phil, you got through on the yellow all the way." It appears that some of those lights stay yellow until the car is through! (TSTM Ch 4: 4.7.4)

Those IT guys don't need to use Backblaze on Linux to recommend it; they're going to recommend whatever "just works" so they don't have to "go down the rabbit hole".

When I still used Android, I would recommend iPhones all the time to people. Why? Because it just works, and I don't want to be stuck troubleshooting their Android issues for the life of their phone.

I also notice this a lot with vehicles, especially in the Bay Area (I blame the abundance of disposable income).

Just because you bought a $12k carbon fiber Colnago with deep section carbon aero wheels (which are heavier and meant for time trials, not commuting) doesn't mean you'll be Lance Armstrong, nor does it mean you'll beat the guy riding a steel fixie who regularly goes on group rides.

Owning an AMG Mercedes doesn't mean you can keep it in a lane in turns (I usually fined quite the opposite) or keep up with a Miata on mountain roads.

Irrespective of that, it's still a terrible idea to be dating in that pool. If we're talking about a 50'000 people company, than maybe it's ok so long as there's no direct business relationship, but if you're the MD of a small company you should simply not entertain dating people within that company. Just the potential for a sexual harassment lawsuit by itself should be enough to stop anything in its tracks - let alone the moral and ethical implications.

> there's no question that Uber lies, cheats and steals

Just to clarify my own comment: I was responding to the parent's statement that "sometimes it takes someone breaking the rules", and saying that it's OK to break the rules by trying to dislodge artificial scarcity, but it's not OK to break the rules by lying, cheating, and stealing; so if Uber has been doing the latter (and it looks like they have), they're not breaking the rules in the right way.
The only issue I have with them is the removal of deleted files from backup archives after 30 days. Crashplan doesn't have that restriction (and also has a Linux client) although the Java-based engine is pretty clunky, and it eats memory like crazy to do client-side dedupe if you have it enabled. They've been promising native clients for a long time, and a sales guy earlier this year said v4.0 was going to be out Q1 this year, which the engineering team later denied ever saying... So I still don't know when the non-Java version is coming with its improved memory efficiency.

Okay, so let's be honest and direct and talk about the system and its inefficiencies. Because so far all this "no sexism" has everyone believe that it is about people, not "the system".

Which is why I am saying, if you care about the people - which we happen to describe with the term "females" in this case - you should strive to include them, not to create conferences, events and groups that "protect" them by isolating them.

If you wanted to do ballet tomorrow, would you prefer a "boys-only" class or a "regular" one?

I don't know, but it could be both? On one hand, most cases of harassment/ whatever never get exposed. On the other, YC thinks they have a good handle on the VCs they are working with, and believe that they are all (or mostly) above this behaviour.

The truth is probably somewhere in between, and it doesn't really matter. Both are explicitly stating that this behaviour is not tolerated and bears consequences.
