50% Cheaper GPUs for cloud-computing / Saving devs 50% compared to AWS
Hey! I’m Nick from Drofika Labs. Felt it was only right to share this on here (posted on Reddit too), as we are in our current beta testing.

We used to process images for companies and then turn these images into 2D and 3D models but ran into a problem, we were used to processing images from 5k acres worth of land but then had a customer wanting us to process images from 250k acres of land.

We crunched the numbers and couldn’t afford the compute price AWS were charging us (Even with our credits etc - You know the story) and we couldn’t find another alternative to help us around this, apart from buying a bunch of servers (Which was a no, no - since we couldn’t afford them at the time).

So what did we do? Lucky for us, Charles (Our CTO) has a PhD in Multi-Core Processing. We reached out to GPU owners (miners for now) from all over the world to contribute their latent GPU power to our marketplace, so that small startups, Artificial Intelligence / Machine Learning developers /PhD students - all with low cloud budgets could get access to powerful GPUs (P100s etc) for at least 50% cheaper compared to the likes of AWS.

Let me know if you have any questions - or would like to join our beta program (if you’re a startup or a developer with cheap compute needs), fill the quick form out on our site.

We are currently saving AI/ML developers from around 25 startups about 55% on their EC2 costs.

Our aim is to provide compute, cheaper … like significantly cheaper. (I have hopes for up to 85% cheaper than AWS but we’ll see).

And yes, we are on boarding more GPUs shortly (thanks to those that reached out in the previous post and have contributed their GPUs to us)

As a working adult, time spent reading a book is both more limited and more valuable than $40. If you wouldn't have bought it anyways, why is it worth your time stealing and reading it?

Although it was an unpopular opinion at the time, I agree with Metallica's outspoken moral opposition to Napster circa 2000.
This is the worst description possible. Increasing taxes doesn't address homelessness -- doing something with that tax revenue does. I just read over Prop C and while it's not the most clear proposal, it doesn't seem unreasonable, and isn't very hard to actually ... summarize its effects, not just hint at the end goal.

ETA: Prop C would add a 0.175%-0.325% tax to large companies, which would go to: administering the taxes, permanent housing (short-term rental subsidies, construction/acquisition of apartment buildings for the homeless, operation of buildings for very low income households), homeless shelter expenditures, homelessness prevention expenditures, mental health expenditures for the homeless.
So Murrow was right. "we have a built in allergy to uncomfortable and diaagreeable information"
From the guidelines:

> "Throwaway accounts are ok for sensitive information, but please don't create them routinely. On HN, users should have an identity that others can relate to."

https://news.ycombinator.com/newsguidelines.html

As recently as a week ago, 'dang had this to say about throwaways:

> "HN can't be a community without members. Disembodied comments are not community members. No one is required to use their real name here, but users need to have some consistent identity for others to relate to. Otherwise we might as well have no usernames and no community at all."

https://news.ycombinator.com/item?id=17996295

And later goes on to make clear this includes "users who create throwaway accounts for everything, including uncontroversial stuff".

https://news.ycombinator.com/item?id=17996858

They also don't see or act on everything they see, so in that sense, I think you could say they "don't seem bothered." That said, I think it's fair to say it's preferred that you maintain some sort of identity.
This is fake news in the literal sense of the word.
that wasn't "they stopped processing my payments for reasons that I don't like"

If you are a business that depends on a given payment processor, when they suddenly stop processing your payments and/or hold back funds without warning, it can be a deathblow if you're bootstrapping. I wouldn't be so cavalier when you're talking about taking away people's livelihoods, especially because these things often happen without explanation or evidence of clear violations of TOS by the merchant.

I'm of firm belief that the principle of proximity is primary for UI design, and color is far below. IMO the recent slew of the ‘anti-bullshit’ “This is a website” pages didn't come close to Matthew Butterick's online-book “Practical Typography,” which is exquisite simply from using carefully chosen margins and fonts: https://practicaltypography.com/
When the primary complaint is lack of transparency in spending you've got to the mythical Churchill 'we are only arguing about price madam' moment: they realise they have social obligations and can't actually say because shareholder worth any more than anyone else.

I believe we all need to be reminded to open our minds and get out of our bubbles. I know I have a hidden bias to read things I already agree with. It’s hard to really try to understand conflicting views without simply dismissing them.
I believe HOT provided some of the advantages of covering indexes.

Covering indexes is tricky in Postgres, due to its MVCC implementation. Versioning info is in the table, not the index, so the index may have stale data. The table itself has to be consulted to find out if the data in the index is actually visible to your transaction.
You’ve hypercorrected. You won’t grow the economy as a whole, but continually replacing broken windows is still great for the glazier.
Other DBMSs have similar typecasting to PostgreSQL, but they're all different. It's one of those things that never really standardised. Personally I like the breadth of different types available in PostgreSQL. First-class enums and ranges really help a lot of apps, and while table inheritance has issues it does have some really interesting uses.

As for features to look in too, I'd look at the in-server functions (plpgsql, plv8, plperl etc) for extensibility. Custom and complex types are pretty awesome as well. Also the range of functionality in window functions can make some really interesting queries possible. Also the concurrency model does need some understanding, as it means a commit will fail rather than deadlock.

Why should use use PostgreSQL over Hadoop? If you have less than ~20TB of data then it's much less complex to set up and maintain, and as long as you don't want to read the entire data set at once it's fast. If you have more but it's easily partitioned (eg multi-tenant) then Citus have a package that can help, or if you have column-oriented data Citus have a different extension to help.

Postgres is also really well tested and has decades of production use behind it, so backups and restores are well known, though that does require manual scripting to copy the files.
To be fair, as written, you'd get a graphic view of every internal organ a spear thrust pierced.

It's not actually possible to depict that visually, as the skin gets in the way.
No, something with "functional" in the title that doesn't use functions isn't related to syntax.

Very valuable but I have to do strain by straijpn searches. There is a great site called datapunk that has many of the missing suggestions with links to the research.
Australia is suffering from a governance crisis in part caused by one prime minister who said 'the role of her majesties opposition is to oppose' and proceeded as leader of the opposition to do exactly that: he caused opposition to rational policies his own party would otherwise normally have backed, including ones which go to foreign policy, a long held space of bipartisan politics.

He even set out to undermine his own leader, when he was replaced. (An attribute he shared with the labor party leadership, thus not exceptional, but undoubtedly hypocritical since he claimed not to do so)

It's only marginally hyperbolic to say that Tony Abbott's time in opposition as leader laid the seeds for a decade of political gridlock. (Including the trashing of climate policy and science based decision making)

The Westminster system has always admitted that some governance issues can and should be shared by government and opposition. It takes an opposition willing to share to do it.
The infuriating thing about React is that, by itself, it has a very high power to complexity ratio. By far the best out of any of the big front-end tools. But for some reason the community absolutely insists on piling 10 tonnes of crap on top of it until it covers every use case under the sun and no single app is using more than 5% of the rubbish they pull in from NPM.
Applications repeat themselves - apps like chat, productivity suites (word, excel), photos - got moved from desktop to web and later to smartphones. If you had developed a first chat app on iphone back in 2009 then imagine the leverage. A new platform is in the making - AR\VR, so keep an eye.

the problem isn't the collective observation. The problem is that there is no symmetrical collective observation that is even possible.

it's not common to see similar anecdotes and think "we" are cheaters:

people cheat. wells fargo, mlb, cycling, track and field, doctors, prosecutors.

not only the employees, athletes, and students, but the ceo's, refs, judges, coaches, and the teachers cheat too:

https://www.theatlantic.com/education/archive/2016/04/why-te...

none of these examples are isolated incidents, and are patterns in our own culture. And if you live in this system, and the one pattern you observe is that Chinese students cheat, then there is probably some bias in your thinking.

I didn't run Solaris in production, but at the time it seemed amazing to me. Thumper's management dashboard looked impressive.

I used ZFS and Boot Environment manager a lot on my personal servers, and it seemed to me way better, easier than what I encountered on other platforms.

macOS of course has virtually no first-party management. Windows has PowerShell and its own universe. I have tried to wrap my head around Windows operations for 25 years. I have never been able to internalize it. Maybe Unix-like thinking has ruined me.
Thanks for introducing me to Nomic games. I think it would benefit those interested in improving on current smart contract implementations to put away the computer for a few days, and just map out the value stream and logical(and often illogical) behavior of the humans, including whatever steps can be taken to supercede the code, in the physical world. I wonder if Nick Szabo had any interactions in this space before coming up with the first ideas for implementing smart contracts. For those interested in the history of smart contracts, check out https://en.m.wikipedia.org/wiki/Smart Contract .Szabo proposes that smart contract infrastructure can be implemented by replicated asset registries and contract execution using cryptographic hash chains and Byzantine fault tolerant replication. Askemos implemented this approach in 2002 using Scheme later adding SQLite as contract script language. The precursor to smart contracts was Ian Griggs idea on Ricardian Contracts https://en.m.wikipedia.org/wiki/Ricardian_contract

Either housing supply has to increase or all those FB/Google employers bringing in employees from out of the state and outside the US, need to stop doing that in areas that don't want to grow.

How are areas to make this determination? By democratic vote? At what level, the almost invisible local electorate? Maybe I'm cynical about the level of corruption in local politics here in NY, but call me skeptical.

And what communities don't want new jobs to materialize? It brings infusions of cash, even if housing demand goes crazy as a consequence. A depressed housing market, if you remember the landscape in 2008, caused a lot of strife.

Nice, I'm posting the Legendre's constantst comment in this thread
OpenStego, steganography application that provides data hiding and watermarking
I just bought one a few months ago when my 13 year old Nokia died. I actually dislike the phone quite a bit and prefer my old Nokia. I have to charge the Razr about every other day, even if I haven't used it for calls. It takes too many button presses to do anything. It isn't very responsive (it takes about 4 seconds for each text deletion). If I receive a missed call or text the phone will vibrate every 5 minutes until I open the phone. This is really annoying in the middle of the night, and when I'm talking to someone at work and my phone won't stop making noise. It supports SMS and MMS, but doesn't actually do well with group texts. Sometimes I can open them, sometimes I can then see what the person sent, and other times the message won't open at all. Also, maybe I'm just dumb, but I can't figure out how to add apostrophes to text messages, which bothers me (especially because I talk to a lot of non-native speakers and I don't want to reinforce poor grammar). Maybe different providers had better interfaces that solve some of these problems, though.

The only things I appreciate about the phone are that it has a USB port for charging instead of a barrel plug, and it can store more messages.
That's a bit too reductionist, right? Or perhaps you could elaborate? As it stands it sounds like "it's all just atoms" when someone asks "how does a neuron fire? Someone must have studied that."
The harm is less people writing books like this in the future. Every dollar this book gets in revenue not only goes partly to the author, but goes into the record as profits for that "genre" of books. Every dollar of revenue for this book increases the value of the advance the author receives for the next book, increases the probability that another author writing the same kind of material will get accepted for publication. The harm you create by stealing this book is that the market for that knowledge is destroyed.

Meh. Masons. The mason lodges were a place a bunch of guys got together in the 18th and 19th century, drank beers and bitched about politics (EG. No football yet). Because of their massive scale and their 'club' feel people immediately assumed a conspiracy. I wouldn't give them this much credit --- as the history channel does on some crappy episode of Ancient Aliens.

Now? I help old mason guys get out of their car door at Walgreens. Their lodges are almost empty, they are dying off in age and much of their lodge real estate is rented out for Justin Bieber concerts [1].

This was really an inspection error. A human can miss a weld, too, so manufacturing lines rely on inspections. Someone was signing off on work that wasn't done. Whether a human or a robot was supposed to do that work is a nit.
You're talking about index-only scans. Those appeared in Postgres 9.2, which came out about 5 years ago.

INCLUDE/covering indexes are indexes that can include extra "payload" columns, and exist only for the benefit of index-only scans. You can add something extra to the primary key for the largest table in your database, all without changing how and when duplicate violation errors are raised.
I need a service that will take my accurate resume and inflate everything so that it aligns better with what is available in the market.
We recently experienced an issue where a recurring subscription in our service was double charged to one of our client's credit cards. It took me three attempts communicating with their customer service before they determined that it was indeed a bug in their service and offered an apology. From our side it was like pulling teeth running through the event log and getting dismissed by their support team. I am still surprised that there was no greater public announcement since this kind of event should never happen with your payment processor.

The razr still works fine (on tmobile). I still use mine, purchased in 2005, no issues. Battery life isn't great and it's hard to find a replacement battery that works, but it still gets me through the day.

I wouldn't necessarily mind upgrading, but the razor is less than 4"x2" and there is nothing else like it available. I have no interest in a larger bulkier phone.
Why corporates continue to use third-party AV is probably a combination of momentum, marketing, and 'something must be done - this is something' but I'm just speculating.
> I miss small phones.

Not quite "tiny," but pretty small regardless, the Xperia Compact line of phones is still a thing. You should check it out. A new Z5C can be had for about 150 USD, or 500 USD for an XZ2C if you can live with 5 inches. Sadly, it's not clear whether Sony will be releasing an XZ3C, so we may be coming to the end of what is arguably the only serious high-end compact smartphone out there.
I think the article's title question has to be restated as 'How much value can you build up from $10K?'

Obviously the title amount is in 'retrospect'. Also it does not imply any specific time-period. A lot of ground work is put into a business idea prior to even forming a company. This is often an undisclosed cost of success.

In retrospecitve with astronomical exits like RxBar's this just sounds like an angel's dream.
Some argue that yes, it’s still racist even if it’s true. Depends on the context I think.
I'm an Indian teaching Indians in India, and there are quite a few students who don't see anything wrong in cheating. Not to say anything about the blatant cases of cheating and mass cheating in school-leaving exams that regularly make the news in India.

I can't say if cheating is more of less acceptable in India than elsewhere, and for sure very many students in India are honest and genuinely interested in learning, but people treating knowledge and teachers as divine is far from reality.

That's a great phone for a kid. I'm looking at phones today after cracking my screen. I have a Blu Advance and I think I'll just get another. Cannot believe the prices people are paying for a phone that they just use for browsing. I'm stunned.

I have a truly strange relationship with the selfie stick.

On one hand, they are incredibly useful in some circumstances.

On the other, I resent their existence and find anyone (else) using them obnoxious.

A selfie stick with a film camera would have truly been useless. You'd probably only get a photo of some random thing behind you, and only learn of your mistake a week later. It took the invention of digital cameras with front-facing screens to make them practical.

I joined as a regular non-manager, non-lead employee. Actually, I started as an intern, and was offered a full time job immediately after that. I was employee #~100.
