I think you are referring to one of two HPE components: Either the iLO, or the iLO combined with a Smart Array controller.

(Dell has equivalent products: For this discussion, iDRAC is the equivalent of iLO, and PERC is the equivalent to Smart Array.)

With those products, the RAID controller (Smart Array or PERC) will be connected to internal and/or external drives, will handle RAID in hardware (ideally with a battery backup write cache), and (through the iLO or iDRAC) generate alerts when a drive fails (or is close to failure).

In the context of ZFS, you don't have that. Your drive controller is either on-motherboard, or a PCIe card like (for example) the (Broadcom) LSI SAS 9300-8e. Those cards do have a RAID option (MegaRAID), but they are often used without.

The rest of the ZFS storage setup is pretty similar to the setup you are used to: Internal drives will have a SAS expander (if needed) on the motherboard, or will use a SAS expander card (for example, an HPE part #870549-B21 SAS expander card). External drives will be in a JBOD that has one or two expanders, and which is connected back to the server using SAS cables. One ZFS difference is that if you have many JBODs, instead of daisy-chaining arrays, you might choose to use a SAS switch (for example, an A54812-SW-01).

With all that I described with ZFS, I haven't mentioned how RAID is handled: ZFS handles RAID in software. RAID Z-1 is equivalent to RAID 5, Z-2 to 6, and Z-3 to 7. RAID also supports RAID 1 (two-drive mirrors), as well as a RAID 10 equivalent (striping across mirrored pairs of drives).

Since RAID is handled in software, and with the physical equipment I described, it is left to the OS to handle almost all monitoring an alerting. The one exception is that JBODs and rack-mount SAS switches (like the Astek) often have an Ethernet connection for monitoring and (basic) hardware control. But even that can often be handled within the OS, using SCSI Enclosure Services (SES, where the enclosure/switch itself is a device the OS can see and query).

I think you got a point here. My reasoning for the machine is kind of the same.
I had a funny experience where a friend was trying to recruit me to be part of some venture.

We met up and got in a car with another lady who he was trying to recruit as well, and he kept talking about it as if it was already a done deal that we were in.

At one point, she and I looked at each other and were like "Excuse me. No offense, but I don't know who the hell you are." We didn't join his thing, but ended up starting three companies together, so we were compatible business partners.

You need some time to get to know each other. I find it's better if you don't consider it like marriage, investing a lot of emotion in it. It either works or it doesn't, and you can leave as friends.

Same here. I wanted to know what it was like to have all of that responsibility on my shoulders.

I felt like my career was moving at a snail pace within BigTechCo and I was capable of much more. There's no real risk in that situation, unless you're borderline destitute, have dependents who need you, have a serious medical condition that requires a high end employer to support you etc.

Even if you fail, you will have learned many valuable skills and perspectives, and might get hired at your previous employer with a better title.
Yeah Germany is a strange outlier. They have all the tech but just don’t trust it I guess?

And yes I used credit as a shorthand for debit/credit.
Also, it’s a distinctly SV mindset that startups and entrepreneurs is this zero/hero dichotomy. The world is full of “moderately” successful startups that throw off a few million in free cash flow for a relatively small team.

If I were to give advice to other founders, it would be stop building for an IPO/acquisition. Build for the middle ground, and take opportunities to step on the gas if you see them.

In stock market you're not playing against other people, including the "pros".

You try to pick companies that will grow in the future.

If you pick well, then it doesn't really matter if other people (including "pros") pick the same company or not because there's enough future growth for everybody.

And I have much less reverence towards pros than you.

The pros were saying that Amazon's valuation is so crazy that even if they sold every book in the universe, it still would be too high. In which they were right except they couldn't see that Amazon is not a book store.

The pros were writing articles about how Nokia is, and will be, the king of the world a year after iPhone debuted and people were camping overnight and lining around the block to get it.

And today an average price target on Tesla is 1/3 of the current price. The pros at predicting future price of the stock are failing spectacularly to do so, despite being paid big bucks by the most prestige financial institutions and having more access to information than anyone else.

While I'm not playing against the pros, I sure am getting better returns than 90% of them.

Insightful article. Zfs is the best file system. Ability to know that you do not have silent file corruption. Running without raid controllers. Feature to take snapshots super fast without waiting and that take little extra space. You can use Cache SSD with ZFS for read acceleration of physical disk. Transparent file compression. Good command line interface. Now you can take good actions with ZED for example sending a notification to an alert system like Slack, ticket system when disk fails or start disk scrubbing/rebuild.

If you are on Linux I can highly recommend ZFS and Minio for S3 like storage. ZFS for local storage.

Recently there was [a thread](https://news.ycombinator.com/item?id=23883270) on Notable and many commented that they were upset that it was no longer open source.

This is something that actually concerned me and so I started using a lot of `bash` scripts to emulate behaviour that I like in Notable, that way I could use Notable without the fear of being locked it but I could try and emulate its behavior in a way that more suited my workflow.

I put the script I use [up on my GitHub](https://news.ycombinator.com/item?id=23883270) and I recently [made a Reddit post](https://news.ycombinator.com/item?id=23883270). I thought maybe you guys could find them helpful or offer feedback?
If you don't have a bank account then it is a good deal to change for free. I doubt those without a bank account have credit cards with good cashback deals.
Seconded. Outer Wilds was absolutely wonderful. The gameplay is lacking in places but after watching the making of documentary [1] my mind is still kind of blown by the technical side, even if it didn't transfer 100% smoothly to the player's experience.

You could make gasoline from the air. A bit inefficient, but if we somehow get to the fabled "free fusion" power plants, it could be a neat trick to have synthetic gas in pipelines flowing from fusion CO2 atmospheric scrubbers.

I lived in the UK for decades, and I don't recall a place that only accepted debit cards. The fees are slightly lower for debit vs credit cards, but they're low for both types of card.

Plenty of places in Europe don't accept AmEx, it still has high fees.

It's true that Germans prefer cash, but that's not necessarily because of the cost of processing cards. Most supermarkets accept cards, but the average German uses a card slightly more than once a week.

I used to have a pod machine, and just found it didn't make very good coffee. It didn't really taste like espresso. In fact, it didn't taste very good at all.

After that, I started using a french press, which was nice, but I like espresso more, and so I got a Sage Barista Express. Great machine, no plastic waste, once you learn to use it you can create coffeeshop-quality drinks at home for very little money–plus you can experiment with different beans.

The difference between a proper espresso and pods is huge.
Last time I tried to estimate that it seemed with a passenger car you get some win there that offsets the battery weight. Something around 300lbs. My guess is if batteries got 30% more power dense the weight penalty would disappear. Part of that is as the weight of battery drops you can make the rest of the car lighter as well.
That's just for the products that can be proven to be fakes. There is also a lot that just are shoddy that you cannot prove, in which case the store loses a repeat customer.

Amazon has already lost me for products where I care about quality. The Pilot G2-05 pens I buy in store ($5 each in Australia) have never had any issues and all worked flawlessly until I drained them of ink. The Amazon 12 pack hasn't had a single pen reach the end of its life.
That's a troubling thought down here in eastern Georgia, where it has been in the high 90F (35-37C) range for the past few weeks, with heat index north of 100F (38-40C), and no shortage of humidity. And that's not even remotely as bad as it gets closer to the Gulf coast.

And it stays pretty unbearable until late October or so.

Yes, I know the article wasn't insinuating that the entire country, regardless of climactic region, should hold outdoor classes. But enough of the US sits below "unbearable" latitudes enough of the year that I don't think this suggestion has much applicability beyond what is explicitly considered "the north". Besides, I've been to New York City in August and September before; depending on the day, the heat, and especially the humidity, can give the South a run for its money.
I strongly believe in Peertube for media creators who want to take control back from Youtube.

Is there market demand for this?

In a world where videos are still sent around as multi-megabyte gif files, and audio clips are still distributed with a random slideshow on YouTube, I think a lot of users aren't so bothered about efficiency - they just want the simplest thing that works.

Lots of music is most efficiently stored as MIDI, yet how many songs on iTunes are midi?

For video, raster is king because it works for everything.
The "undergrad Year 1 at École Polytechnique" is really the junior year, since the freshman/sophomore years of university education would have be done in prépas. It is undergrad, and it would be their first year at the school, but it is quite misleading to call it "undergrad Year 1". Given that undergrad is three years in France, "undergrad Year 1 at École Polytechnique" means "last year of undergrad".
I‘m about to found a UG in the next few days, so I‘m curious why you say that I should found a GmbH rather than a UG.
Woah this is incredible. Even with the increased CPU demands, this is a very large bandwidth savings.

>In practice however, DRM, streaming , analytics and ad placement also require javascript logic to function in web runtimes, so in real word settings web-video playback can and does use a non-trivial amount of CPU time.

I'm a little skeptical of this claim. No idea how much CPU is used for DRM, but I can't imagine it's on the order of multiple percentage points.
> We are not a monolith

This is something I absolutely agree with you on, and I think it's a disgrace that so many people — usually the most rabid — on both sides of the argument use the opinions of a fraction of some group as political ammunition.

> a lot of the defenses against even considering that change sound racist as fuck to me -- there's lots of people who explicitly argue the status quo is OK and that it couldn't be worth any changes here.

The status quo in which regard? The status quo with regards to police brutality in the US is obviously not OK, but the status quo with regards to words having multiple meanings and being able to be used in different contexts should be fine.

> Master/slave, however, does bother me. It's led to one too many conversations where people need to, or so, say things like "the slave isn't keeping up with the master" or "the master should detect that and kill the slave" or "we should add more slaves" and those words are grating to me. I don't want to say them, and if a coworker is saying them sometimes I'm not sure if they're enjoying getting to use those words a little too much.

I'm not denying your experience, but it sounds like your complaint is against racist assholes in your vicinity. I'm not [yet?] convinced that stopping them from using those words specifically will change their behaviour or perspective.

> I also want to add, none of this is as important to me as meaningful reparations for slavery and institutionalized racism.

I recognise that, and it's a view I share. My ancestors also suffered under slavery (much more recent slavery than the US slave trade) and their country is still asking for reparations.

> But the fact that other things are more important doesn't mean this isn't important.

I'm not suggesting we engage in whataboutery, but at least from my perspective lesser complaints undermine more egregious complaints, and for the sake of practicality I prefer to choose my battles.

In any case, while we agree on some (I think most?) things, I don't feel any less uncomfortable by the attempts of some people in society to normalise Orwellian newspeak. I do appreciate that we can discuss this thoughtfully and respectfully though, and I appreciate you sharing your perspective.
> which involved two iterations on the design before the 2018 edition released

Just to be clear, I have the highest respect fo the Rust core team, I've followed some discussions and you guys are going above and beyond carefully weighing all the pros and cons, often to an exhaustive degree.

I feel the main strength of Rust is also its biggest weakness: alway striving for the perfect, platonic ideal solution, and going the extra mile to get there, which then might discard a much simpler but slightly less powerful solution. Often thats a good thing, not sure it was warranted for the module system. I remember there were different opinions in the core team, Aaron being a proponent of the simple version I think.
That's interesting. Do you generally not check if the item is sold by Amazon.com itself?

For me, I still prefer Amazon if it is a high value item, I check the seller though. I prefer to have my contact information/payment information stored by a company I can trust to keep it safe and in as few places as possible.
I think they just don't want you to serve large stuff, because their CDN isn't optimized for that.

I serve all kinds of files <10mb via CF, that includes audio, video, images etc.

Files over >10mb I handle myself. Around 100TB is handled by CF each month and around 700TB by my own servers (4 Hetzner dedicated servers).

The whole setup costs me around 300 euros/month paid to Hetzner, and 20 to CF. That means I pay around 40 cents / TB.

So far CF hasn't complained, and I've been using them for years. Though they try to pitch me their higher priced plans now and then.
It can be sane. Just be very selective who you allow. I maybe follow a hundred people or so, but my block list is probably ten times as long. Even blocking anybody with "pronouns" in their Bio already helps a lot.
> Sure it does. I've seen lower middle class people become millionaires that way. Of course, one needs the discipline to not succumb to spending it on a car/house/divorce, and the intestinal fortitude to not panic sell when the market tanks.

I think he was referring to the adrenaline rush, not the potential to make life changing amounts of money playing the long game, which clearly doesn't yield the same 'rush' he was referring to but is none-the-less an effective strategy.

I'm an unabashed adrenaline junkie: I've been in martial arts, school sports, motorsports, I did regular public speaking engagements for my startup and in academic-based oratory before that, and spent time in high end Kitchens... but with that said, to this day I will never understand the mediocre adrenaline 'hit' you get from gambling. It's really low level stuff to me, like lower than lifting weights or running a mile, something I did regularly at the gym after getting beat up working an 11 hour shift of a busy Dinner service.

I used to play $10 buy-in tourneys of Texas-Hold'em (forced into is more like it) hosted in the living room next to my bedroom when I was in my late teens/early 20s in Motorsports and I often got so bored, even when I won, that I failed to stay in if it went longer than an hour and often asked to take a cut on my pot/payout and forfeit to just get some sleep as I had school and work in the morning.

By contrast my professional driver friends/roommates were up until 5am and one of them played online for high stakes, the other played the stock market on the side and said it felt like the same 'rush,' as a day at the track but I could never relate to either of them as a track day was way more intense for me.

Flash forward to my Bitcoin days and after the initiation you get from from a couple of years in that space with such absurd volatility and all that the drama that follows it is such that nothing really even compares to it anymore, and I wasn't even a day trader, I'm merely an early(ish) adopter so none of this makes any sense to me at all.

What I do know is that this was done for gamblers [1] after COVID and is slowly becoming the norm in legal states that have re-opened due to the demand these, quite frankly addicts, create for the Casino Industry.

I wonder if something like Neuralink could help mitigate these diseases, as it all seems to stem from a neurological/neurotransmitter stimulation/feedback loop. I'm less concerned with the Matrix-style downloading/AI integration and more focused on what it could do for people with severe Depression, Alzheimer's, Parkinson's, and ALS.

There's nothing wrong with the taste of Nespresso (it's a little weak for me, but that's personal preference). The reason why coffee pods are awful and need to die is the sheer, disgusting amount of pointless waste they create. Every single cup of coffee requires a small, non-degradable, hard to recycle piece of plastic. Making coffee with a normal espresso machine is so easy. You can learn how to do it in 5 minutes (not barista quality, but at least as good as Nespresso). If you think that cleaning up the mess from a coffee machine is too much work, you are just lazy.

The only benefit I can think of is that you don't need a sink nearby. But in every case where I have seen a Nespresso machine, there is a sink within at most a two minutes walk.
It's a good point. Internet speeds are also quickly increasing in areas getting online for the first time.

I have only come across the great replacement theory twice and both times it was in this exact context. Somebody being accused of dogwhistling to it. Small sample size for sure, but also a strange phenomenon no?

I think what you are engaging in is quite dangerous and I believe it must come from a real ignorance of the other side's way of thinking.

You think, to have those opinions, they must have some underlying racist beliefs, and lo and behold, you find the evidence in the most innocuous of places.

This is not really the next phase - retail has been on a downward trajectory since the first online sale was made. The spiral down just buffered by a global economy that was growing.

Working with Westfield back in 2008 there was talks already of redesigning mall footprints to have smaller stores that can act as pop-up shops/ collection points etc. However there was an overall equilibrium achieved as malls started playing into the idea that their differentiation was on "experience".

Shopping and going to the mall remains a highly social activity. And I believe will survive well past the pandemic. And perhaps stores will be smaller individually and act as both in-store sales, collection points for online purchases and pop-up stores to market new products.
