I got a HP Compaq Elite 8200 with a i5 and 8GB of RAM for 50 bucks on Newegg about a month ago. And shipping was free too.

I stuck in a spare ssd and 8TB drive. It is running Ubuntu.

Right now it acts as a pi hole, nextcloud server, Channels DVR server, Plex Media Server, and runs Transmission. It barely breaks a sweat.

I used to just have a Pi 3B+ doing duty as a pihole and nextcloud box.

This works better and overall cost less than the pi once I added in the sd card, case, fan, power supply.
Exactly, it's those kind of questions nagging at me :)
Managing swap in the modern Linux system
With the move to $0 order fees for online brokerages, not surprised to see more tie-ups. Even running the business at break-even, MS gets to market their other products to all E-Trade's customers.

That said, what's the current economic model for independent online brokerages?

Hi guys!
I hope I’m able to contribute by bringing some of my own experience and real data to this discussion. I'm the founder of Classpert (https://classpert.com), a search and comparison site for online courses. In the last 6 months, we’ve managed to sell over 2000 courses, in 8 different languages and across 80 different countries (Udemy alone is selling around 200 courses each month through Classpert). So while it is true that price has an impact on low-income customers (especially from developing countries), even for developed countries (USA, Canada, Germany, Japan) Udemy still is leading the race in number of sales (at least if we use our database as a proxy of the market)

Much of their success stems from the fact that Udemy has by far the largest catalog of online courses on the web (something around 110k courses). And while some people may argue that this comes at a cost of providing low-quality courses it also naturally provides an extremely aggressive long-tail SEO strategy. The majority of potential customers don’t correlate e-learning platforms and quality (most of their customers are not high-profile HN users), so if you are googling for an online course chances are that Udemy will be ranked at the top (and on a global scale). This also explains why they have 10x more traffic than Pluralsight or 3x more than Coursera.

On top of that (an here is much more my personal intuition than data-based analysis), Udemy not only offers cheaper courses but also has not yet adhered to “subscription models”. Subscription models target specific users. Subscription models are awkward and feel totally unnatural to most “normal users”. Why on earth a normal user, seeking for a specific bit of knowledge will lock himself on a subscription? The subscription business model seems to work much better on B2B than B2C.
I was reading now that photons when created are already at light speed, they don't accelerate. That's because they are in this instance a wave, and a wave is a distortion of its medium; the whole wave can instantly be created at a certain speed (for example throw a rock into a pond, the waves will immediately radiate at speed).

So in reverse then, when absorbed the wave could be cancelled out and it is forced into particle behaviour?
I moved from a Pi server to a mini PC with a Ryzen processor and 16Gb RAM after even the Pi4 with 4Gb was starting to struggle with the number of tasks it was running (Unifi controller, Pihole, Home Assistant, etc - none of them are massively power hungry, but together they made it crawl at times). Still have a Pi next to the TV for media display, but it's mostly due to better subtitle support than the TV's built in streaming apps!
What do you use to automatically rotate the certificates from Sectigo? This doesn't seem to be a set it and forget it solution.

Also, with Sectigo you're more likely to get an actual broken certificate. They misissued nearly every certificate starting from 2002 until late 2019 [1].

Is there a database file format that supports columnar storage query able via SQL? For OLAP style queries.

I've tried SQLite for this usecase but the query falls down when querying millions of rows.

I know there is parquet file format but I'm wondering if there is like a SQL engine that can sit on top of something like that similar to SQLite

This is a common tactic on Amazon. But if Amazon finds out it’s over. They are pretty strict with any seller to customer communication even without the scam part. Just asking customer to visit your website is a violation.
Thanks. The only thing that doesn't click with me and a lot of these kinds of sites, is that I was never an Apple user. There were some at school, but I started with early Windows. Not making a value judgement, just saying I have very little nostalgia for Apple because I didn't use it.
True, but when one of the parties appears obviously young and the other not, people tend to get creeped out by it just the same, and in kind of the same way. As sexual taboos go it's not the worst and the stigma isn't always fair but it is what it is.

I attribute a lot of that to the increasing youth-orientation of modern culture, since "May-September" relationships have been common throughout history, although legitimate concerns about abusive power dynamics and exploitation do sometimes arise in the modern context.
In general, compression works much better the more data it has to work with. When you're talking about one or two KiB files, the overheads are going to eat into a lot of your gains. It's definitely still worthwhile, but I can see how a custom packed binary format could easily outperform a compressed text format at these sizes.
Technically speaking if you rent a car you don't actually own it, so I don't think this goes in the same category as other DRM-fails.

This makes perfect sense, and it seems that the article spends most of its time "selling" vector.

As a designer, I ALWAYS start with vector (usually an Illustrator file).

No need to sell it to me, but I'd gently suggest using existing vector formats, like SVG.

That said, most operating systems don't support the use case described. It would be nice if they did. That may be coming, but for now, we are stuck with BitMap. I'm glad that I don't need to use the damn .ico files anymore for Web sites.
It’s not inconceivable that the car could use a BLE connection with the app to be unlocked and started, at least as a backup when it can’t reach a cell tower.

Having no mitigation at all for the car not reaching the Internet on its cell connection is negligent. Even a hidden screen that lets you put in a one-time use startup code in the case of emergencies would have helped.
Sounds like Google. Either you know somebody deep in there or you are lost with your request. Your problem.

I've got a working macOS Winamp-inspired music player I've been working on. I was thinking of open-sourcing - anyone here interested in something like this?
If a bug happens in more than a handful of implementations, there’s a good chance the protocol is to blame. Perfect examples of where this emphatically is the case is MDC (PGP and Telegram are the only two common protocols in use I can think of where you don’t get a real MAC) and JWT’s alg debacle. Both were obviously ridiculous, and both led to serious vulnerabilities in almost every implementation under the sun.

Mind you: with efail, some tools were using GPG directly. GPG produced unauthenticated ciphertext. GPG is also the dominant implementation. If GPG itself does this obviously broken thing, how do you expect third party implementations to get it right?
I truly believe my children (not born yet) are going to buy their first car and it will be fully autonomous.

Too many people my age and older will be apprehensive about giving up control, despite it likely being safer. So I think it is fair to say that in 20 years there will be many people who learned to "drive" with a self driving car and their parents and grandparents will refuse to give up driving themselves.
Linux Academy's lab based approach is pretty helpful, but sometimes their course content (videos) is pretty horrendous. Some of the course content (particularly Kubernetes and other container related courses) often seems like it is made by people who aren't as familiar with the technologies as they think they are, or are just not capable of intelligibly organizing slide decks (making things headings that shouldn't be, leaving elements out of lists of items, etc.).

I think it's another stream of data feeding the model. For example: you see a child walking along close to the edge of the road, not looking in your direction. You don't slam your brakes on, but as a driver your prediction is that he may step in front of you, so you ease back on the accelerator, move out further into the middle of the road, cover the brake.

I love Twitter this way, which is built "offline first". Twitter will let you read everything in your timeline that you have previously downloaded, let you reply to and like as many tweets as you want, and never complain about lack of connectivity. It'll just dutifully queue your requests and act on them once you're back online. It's one of the only connected apps properly usable on the subway.
That doesn't invalidate GP's points. A collection of B&W icons with similar base shapes (circle, square, rectangle) and no contrast is terrible for using the interface. Each icon needs a distinctive element, be it color, weight or shape, to make it stand out from the other icons near it.

If you're designing a B&W icon set, at least make sure that each one has a very eye-catchinge, different outline.
Show HN: Configaro – A tool for creating config templates for network devices
I work for a internet/managed service provider and we generate a lot of configs. Over time we've built a variety of techniques for doing this, the most common, similar to many others, is for us to maintain "base configs" and snippets for various scenarios (statically routed, dynamically routed with failover etc etc.) and then we have internal docs with step-by-step instructions on how to create the right IPAM entries and build the final config.

This works well most of the time but every so often we might rush a config, miss a step or put the wrong value in for field - the best case is that the issue is noticed and we can fix remotely. The worst case is that the job fails. We also found that sometimes engineers would build up their own custom flavours of base configs and snippets on their own devices.

We wanted something better. We looked at using a templating language but we didn't love the work required to install the correct toolchain and after some testing, found that providing the values through the CLI to be a little restrictive and the process of building a template more daunting than we wanted.

So we built something ourselves, and we're now releasing Configaro: https://configaro.com

It's an entirely online, you build the template and specify what variables it needs and place them in the right place. Then later you input your variables and it spits out your config. There's currently one "advanced" variable: IP Address with Subnet, if you create one of these it automatically provides you some derived values such as the host address, subnet mask, mask length, wildcard address, first usable, last usable which helps remove a big source of error.

We've been using it for the last few months and it's working really well, engineers prefer using it as it's quicker and we've found it good for sharing little snippets.

I'd really love to know what you guys think about it, any ideas or feedback would be awesome!

Aw man, I just got moved from Capital One 360 Investing to E-Trade. Now I'll have to move to Morgan Stanley? Any way to just transfer my sh*t from E-Trade to Robinhood without just selling and re-buying, incurring a change in tax status? Seems Robinhood has unfortunately sunset that option...
My belief is that we'll be replaced when vast swathes of roads are replaced with ones designed for automated vehicle transport, which is a fair way out of my lifetime I'd imagine.
None of that is relevant to my comment. Sustainable power sources can be used to manufacture carbon neutral jet fuel. This has already been tested.
I see, so you can verify but it's not by default. What happens if you add a new device (e.g. a tablet so a new fingerprint, which is different from changing main device where the original fingerprint changes)? Is the new fingerprint accepted without user validation?

My point is that e2ee makes sense when you don't trust the server (here Signal company, or FB for whatsapp), so if most people don't check the fingerprints (and I assume it's the case), what's the real value of it?
> The Lies of Locke Lamora, I think it's a good first book but almost everyone I've spoken to/read comments from agrees is bottoms out in book 2 and 3. Personally think the same of Rothfuss' work.

Well to add to your data points, I disagree with both statements that the gentlemen bastards and the kingkiller chronicles get worse.

I think they both depart from their source material in the second books but do so necessarily in order to create a standalone story that isn't formulaic.

Especially with regards to Locke, the author made some incredibly bold kill-offs at the end of book one which left the question of how to follow up with a sequel. I'd say his strategy of consolidating the key characters while expanding our knowledge of them through flashbacks is very compelling. I can't get enough of their origin stories and allows me to experience the "dead characters" again, albeit in small quantities. I'm also a huge fan of how powerful wizards are in those books, it seems closer to how unbalanced a mage would be wandering around our world and the fact we follow non-mages really sets the tone for uphill battles.

I think "prediction" in this context means something different. It's not specifically that self-driving cars will optimistically assume they know what other drivers are doing, like a naive driver might (although that is a form of prediction). It's more generally that in order to make any smart decisions at all, the AI has to model the future.

For example, if you are driving behind a car on the highway, and the car _in front_ of that car puts their brake lights on, you may want to pre-emptively start braking now now. That's a type of pro-safety prediction made based on your understanding of the likely future that driving AIs should also have.

A few years ago YouPorn publicly announced using Redis foto run most of the website, as a primary database, not just as a cache.

Before joining Redis Labs (1yr ago more or less), I wrote my own Redis module while consulting for a fintech startup to use Redis as a filter for credit card transactions. I liked how the solution turned out and it somewhat alleviated the pain of having to work with the iso8583 protocol.

Today I know a few of our customers using Redis as a primary database and the company is investing in that direction.

I'm a Developer Advocate so one of the main pain points that I see is the lack of tooling for primary database use cases, but I think the situation is improving.
The problem wrt tools is that you can't just copy paste what works for other ecosystems to Redis. You have to rethink many things from the ground up.

As a (positive) example, take a look at this Python O"R"M for Redis: https://github.com/limpyd/redis-limpyd
That’s true, but they’re not widely supported, so you can’t count on them to communicate. It’s also really hard to know for laypeople if the result is safe or not, so it’s dangerous to train them to accept encrypted ZIPs. Plus, as long as you don’t care about compatibility, you’re probably better off with encrypted disk images (DMGs or LUKS), because they don’t have completely dominant unsafe implementations.

"Is it easier for a pan European company to keep big US competition like Robin Hood and Ameritrade out?

Niehage: 'The companies you name are very badly positioned for Europe. Their economic model is based on two pillars. Firstly, they want to offer everything for free. But if you offer all services for free, you have to earn money with the capital in the investors' accounts. That is possible in the US, where you can still get 2% of interest. In Europe, with zero interest rates, that's very different.'

And the second pillar of their economic model?

Niehage: 'That's the high frequency traders. As far as I know, Robin Hood sells its customer orders to this kind of parties. They are prepared to pay good money for that. According to the European MiFID II-regulation, that is illegal. Those two examples show that the US and EU markets are totally different. That's why American brokers have difficulties breaking into the EU market.'

If Uber had bothered to follow a basic safety protocol that person would still be alive today.

Staying alert on watch is something that nearly every solider, security guard, sailor, will have to do. Where you basically stare into the dark in case someone comes.

There are a number of ways to mitigate the inevitable failure of attention:

* Having a parter;

* Doing short shifts (change with partner);

* Very simple non-distracting tasks - like reading out to your parter a figure at a glance.

You certainly should not:

* Be on your own;

* Have a mobile phone on you (all screens should be locked away while moving).

It's so fucking arrogant that Uber didn't care to implement the most obvious risk mitigation. The cost of an additional person on watch is negligible compared to the cost of their self driving care program. My gut feeling is Uber simply misled regulators with how developed their self driving car program is, so it could continue to mislead investors.
I rely on Matt Levine to explain, more clearly than I could, how brokerages make money ("The Trades Will Be Free Now"):

https://www.bloomberg.com/opinion/articles/2019-10-02/the-tr...

Let me highlight a key passage:

"Even this understates the change, because the actual way that stock brokers work today is that you keep some cash in your brokerage account to fund potential trades, and the broker earns interest on that cash and pays you less than it earns, and all the trading stuff is almost irrelevant. ... Commissions are way down there; in 2018, they represented a bit less than 7% of Schwab’s net revenue."

I don't think this is about consolidation in the brokerage space because of zero fees. I think this is about investment banks getting into the retail space (see Goldman's Apple card).

Once again, I rely on Matt Levine to explain it ("Goldman Has Some Boring Plans"):

https://www.bloomberg.com/opinion/articles/2020-01-29/goldma...

The whole thing is worth a read, but here is one key paragraph:

"One way to interpret this is that Goldman has embarked on a quest to be boring. This interpretation seems plainly correct. The old Goldman approach—making a lot of money on lumpy investment-banking fees, risky balance-sheet-intensive trading, and both-lumpy-and-risky principal investing—is disfavored in modern banking. It is disfavored by regulation (the Volcker Rule, capital requirements) and by market conditions, but it is also particularly disfavored by Goldman’s own investors, who want reliable recurring revenues."

Edit: I should add this interpretation is also the one offered by the author of the NY times article, although the author also claims that slashed fees played a role:

"It continues Morgan Stanley’s strategy of increasingly focusing on asset management rather than investment banking and high-stakes trading, betting on steady fees over bigger paydays and bigger risks."

Using uranium class or ceramics for eating is not recommended.

Not because the radiation it emits while intact. Alpha radiation is the primary form of U238 and it does not penetrate skin. But the chip and wear in everyday use means that you get particles inside your body. Alpha radiation inside body is bigger risk and uranium is also toxic and reproductive toxicant.

The largest radiation hazard in home is radon gas in indoor air. If you live in an area with lots of radon emissions it's good idea to have ventilated crawl space under the house.

https://www.epa.gov/radtown/radioactivity-antiques

> Do not use ceramics like antique orange-red Fiestaware or Vaseline glass to hold food or drink. They can chip, and you can ingest particles of uranium with your food or drink.
