> Between 9.20 and 15.12, 7-Zip produced nothing but beta versions for 5 years.

That's not all that surprising. The software was 10 years old when v9 came out and the major version number is just the year of release. There aren't 5 major releases that never got out of beta. The major version numbers in 7-Zip are misleading this way because the author doesn't really conform to standard conventions. Of course, that is pretty obvious once you use the software for awhile. It still doesn't properly support UAC.
Hygiene regulations don't require visible cleanliness (i.e., clean dishes and sparkling floors), they require hygienic practices and workplaces. The big things are storing and cooking food properly, making sure that employees clean themselves and the kitchen in a proper manner, and controlling pests like rats and roaches (which is 90% accomplished by the first two). Everything beyond that is negotiable.

LA County, for example, is very strict with enforcing these rules for kitchens, and publishes monthly lists of restaurants that have been shut down for violations.

Well that's depressing.
I believe they are asking about the business use cases for putting things on the moon.
Most don't, but some do.

However, (and I think this is pretty obvious) the point is that shooting for 90k to start in an incredibly high-cost area, for a difficult specialization in a field that's in super-high demand and that has historically been considered to pay a lot of money isn't going to be as great as it sounds.

I am constantly amazed by the productivity of top computing experts in the 60s and 70s. They managed to accomplish so much in such a short time, while working in small teams, on ridiculously slow hardware and having next to no libraries or tooling.

In the corporate world today it often takes a dozen people and a few years to create what's effectively a website that records user inputs to a database and occasionally sends emails.

I understand that I'm comparing top programmers of the past to average programmers today, but I think modern tooling and accidental complexity of our computing environments plays a large part here as well.

Home values and bankruptcy have been public record for a long time. There is a public interest in being able to see all transactions and history on property, and it’s important for debitors to be able to know when people have declared bankruptcy. Part of filing things in court is that it becomes public record.

In a strong economy like our current one, upward pressure on wages overpowers downward pressure. When there is a tax cut, that net positive pressure doesn't disappear. So in the lower tax world a business can give in to wage pressure with less cost to itself than in the higher tax world.

Now in the lower tax world there is also the allure of higher profit without any wage increase as compared to the higher tax world, so the issue becomes one of balancing the desire to give in to wage pressures and the desire to increase profits which is a decision that must be made on a company by company basis.
Yes, the way 7-zip releases are done is not ideal and the versioning scheme is just weird. I wish he would make his versioning clearer.
It depends of what you want to do. In most cases, I would recommend using and existing client/library, this would make the things more easy for you (don't have to start from scratch, something already made in your favorite language).

If you really insist in doing all by hand, you can start by checking compliance suits (XEP-0375) or https://xmpp.org/about/technology-overview.html. Those two links are actually at the top of the XEP list (https://xmpp.org/extensions/).
I think you are misinformed about the current state of watercooling (even AIO). I'm running a very hot overclocked machine running extra voltage than normal. A 280mm radiator is an improvement over even the largest copper hsf.

As for the gaming card - it's not top of the line (that would be Titan Xp and Titan V) - but yes it's very high-end. So why did I opt for that? Why not? I do a ton of 4K gaming and VR as well. Definitely not the primary goal but a nice side benefit. I mention some of the games I play in the setup section.

As for the pricing - obviously monetary concerns were not much of an object with this build but the price of my graphics card has doubled since I purchased it. And RAM has gone up another $100.

But yes - it will get outdated in just a few weeks. The benefit of the PC is that I can just swap out an upgrade to the next high-end thing over a weekend when I want. I already did that once - this build started out as a 7700K cpu/mobo and I swapped them out for an 8700K before publishing this.

I have to say it hit me and I was like... damn I should just do that. Forget all this blogging platforms and getting caught up in look and feel. Just write text files.

Even with Jekyll (and its variants) I got caught up on making it potentially look nice but this person just said ... f-it... let google and github figure out how to organize the content.

> I don't know who wants to make a pure directional bet on bitcoin going down at the moment

There's a line of reasoning that if no one thinks a security or asset will fall in price that's the best setup for it to do so. (If everyone thinks it's going up, from where would new buying money come?)

I don't have a position in BTC (or any other coin), but I think it's likely that BTC hits $5K before it hits $20K.
Oddly, Lightroom does not parallelize across multiple photos in a job. Try cutting your photos into smaller batches and launching multiple batches in parallel.

A larger issue that I see with worldwide adoption is that Apple considers iMessage to be a moat that keeps people tied to its devices.

Study: Neural Basis of Cognitive Control over Movement Inhibition: Human fMRI and Primate Electrophysiology Evidence

Citation: Xu, Kitty Z.; Anderson, Brian A.; Emeric, Erik E.; Sali, Anthony W.; Stuphorn, Veit; Yantis, Steven; Courtney, Susan M. Elsevier Science Neuron. December 2017.

Summary: Executive control involves the ability to flexibly inhibit or change an action when it is contextually inappropriate. Using the complimentary techniques of human fMRI and monkey electrophysiology in a context-dependent stop signal task, we found a functional double dissociation between the right ventrolateral prefrontal cortex (rVLPFC) and the bi-lateral frontal eye field (FEF). Different regions of rVLPFC were associated with context-based signal meaning versus intention to inhibit a response, while FEF activity corresponded to success or failure of the response inhibition regardless of the stimulus response mapping or the context. These results were validated by electrophysiological recordings in rVLPFC and FEF from one monkey. Inhibition of a planned behavior is therefore likely not governed by a single brain system as had been previously proposed, but instead depends on two distinct neural processes involving different sub-regions of the rVLPFC and their interactions with other motor-related brain regions.

Highlights:

• A context-dependent stop-signal task with human fMRI and primate neurophysiology

• Task design, data types, and analysis methods enable dissociation of system components

• Multiple distinct parts of rVLPFC and interactions with other brain areas required

• Context-based attention, interpretation, monitoring, but not direct response control

VX: Science, Made Delta [humour]
This is a favorite fantasy of what would today be called the "America First" movement.

In reality, the EU is world's largest economy, with about 20% of world GDP. It is also under the "rule of law", even more than the US by some measures.

In such a society with a long history of democracy and judicial independence, it is almost by definition impossible for a company to be ruined by government action unless it commits universally-recognised crimes (fraud, corruption etc.) or its business by nature entails equally recognized negative external effect (tobacco, environmental damage,...).

Because of the undertone possibly hinting at nationalistic motives (i. e. Europe harming a foreign competitor for its own business' benefit), I'll also point out that fines by the EU have historically tracked almost perfectly with the relative size of world regions' activity in the EU. In other words: European companies make up, say, 60% of the European market, and are also hit with 60% of the total fines.

The only divergence from this correlation has actually been a slightly lower number and amount of fines against US companies, and slightly higher enforcement actions against Asian companies. I believe this is most likely caused by the US' own national enforcement (and, as a result, corporate governance) being in better shape than Asia's.

It's more a marketing spin than anything. It's an interesting time-series focused solution extending Postgres to become a more scalable database with built-in smarter time dimension handling. A distributed column-store database would do things just as well for queries and ingest, if not better, but it's always good to have more choices.
That and Structured Computer Organization. MOS is software-focused, SCO is hardware-focused. Both have some overlap, of course. Meltdown/Spectre are hardware bugs at their core, so having a more thorough understanding of hardware is helpful with them.
"Science does not remove the terror of the gods."

There are two (at least) modes of relating to the world, one is a disassociated analytical stance, the "objective" observer, the other is an associated experiential stance, the "subjective" observer. The former leads to science while the latter leads to mysticism. Like the wave/particle models of light, each both gives something and takes something away.

If mathematical models are starting to bore you it's possible you're getting ready to explore subjective reality? (E.g. go to an aquarium and really look at a jellyfish.)
Different projects have different needs certainly, but its nice to see a readme that gives me some context to what the project is, and how to actually run the code, install needed dependencies if it's not obvious. Also probably worth acknowledging shortcomings or places for improvement in the readme, so your reader is aware that you're aware of any deficiencies.

If you want to do a longer recording and you want to keep the whole thing (or substantially the whole thing), QuickTime Player is better. I also use, and love, ScreenFlow for doing screen cast type videos. The difference is, I'm not going to leave QuickTime Player or ScreenFlow recording all day because of disk space concerns.

As for 10.11, it probably would work if I just changed the target OS, but for a little side project I didn't feel like going through the trouble with testing 3 operating systems.
"We realized that this problem needed a new kind of database, and so we built TimescaleDB: the first open-source time-series database designed for scalability and complex analysis."

Or, is it just that TimescaleDB is 'opensource'...
We use process historians, and it's unlikely we will ever get off them. Industrial process historians are hard to replace because of the multitude of corner conditions that they handle, a result of being hardened over 3-4 decades of being deployed in industry.

That said, most process historians are really not optimized for analytics use cases, which are becoming increasingly important for extracting value. They also don't scale too well horizontally, and are unwieldy to work with on the large. (typically they're used for visualization, and you are typically only able to work with small subsets of the data at a time, like when you're troubleshooting operations at a particular plant, as opposed to finding patterns across all plants which is more easily achieved with something like Timescale).

I think an ideal setup for me would be to get historian collectors to tee their data to both the historian database, and to something like Timescale. I do a lot of large scale time-series modeling and would really prefer to work with a SQL database than a historian API.
I've experienced both kinds of low involvement, but I was definitely referring to cases where we shared values.

A case of indifference is still preferable to tyranny, though it obviously comes with its own set of problems. The biggest issue I have with uninvolved managers is the conflict between knowing what's expected versus the level of autonomy I should have. This problem is not isolated, of course. But an uninvolved manager may grant a lot of autonomy while failing to make it clear to their employees what sort of decisions they cannot male autonomously. As an employee, I will only ask so many questions before deciding the system is ridiculous and then overriding it. That's just my nature. If something is so important to a process, like communicating with a bunch of anonymous suits on Mount Olympus before a major release of one particular product, that information should be handed down to me. I shouldn't have to pry every detail out of management to get my job done, and occasionally they'll be punished when I make an arbitrary decision.

A good manager should be able to provide relevant information and facilitate the product process while staying out of the way. If they're always too busy attending meetings outside the team, then they'll reap what they sow and have no one to blame but themselves.

By the way, I do not make character judgments on most managers. Most of the people who've managed me are great people outside the office setting.

> There's no real benefit of that much RAM in Lightroom

This really depends on what you are editing. 13mp snaps from your ancient DSLR? Yeah, no point. 52mp snaps from your digital medium-format camera? You'll probably want more than you'd think. 4x5 or 8x10 negative scans? Open the bloodgates.

(and remember that by default Lightroom does not parallelize across multiple photos within a batch job, so multiply your measurements by 4x or whatever if you're going to be launching multiple batch jobs at once to fully occupy a high-end processor.)

128 GB is overkill, but there's a solid justification for at least 32 GB or 64 GB for power-user situations.
Showing up sometime between 8 and 11 is unreasonable, because it prevents people to come sooner then at 8. It should have been "sometime between 6 and 11" to be proper.

Also since people know the guy in your story is not working enough, it should be easy to check on him couple of times and then fire him.

Thanks! After reading that article I'm curious where public key cryptography fits into this.
I think the key there is not outlook but all its friends that get dragged along like cobwebs. First there's Exchange, then AD, then the whole CALs thing, then you need spam and malware filtering, then there's archiving and backups, and don't even talk about client compatibility and upgrading all the desktops and _THEIR_ licenses. Or you skip all that and pay the other hand with 365 seats.

So it's not just Outlook, because it's designed to be not just Outlook.

I am not sure how many people have an issue with this, but it seems to me that computer science, just over the relatively short time I've been paying attention, is becoming more-and-more abstract in a lot of ways.

You can code something incredibly complex that works great without understanding any of the math underneath. Understanding the math arguably makes you a better engineer overall, but isn't required to solve many of these problems.

I think it's pretty cool, but I'm sure a lot of people have a big issue with the "just TRUST the library!" approach.
Ask HN: Please, help me understand how I can improve my workflow
Hi, HNers!

I desperately need help scraping the Top 20 URL links (and titles) from Google's SERPs for a bunch of keywords.

Why I need the URLs and titles:

I am launching a personal blog (my very first site) and need to understand the i) type of content that ranks and ii) design a backlink strategy that has a chance of working (by reverse engineering backlinks of future competitors).

Having a bunch of links that I can then plug into ahrefs.com will help me out a bunch (money is tight so I will be using ahrefs $7 7-day trial).

What I have already tried:

- SERP Scraper from urlprofiler.com - Unfortunately, it took me ~20 hours to get the top 10 URLs and titles for 195 keywords.
I cannot use proxies because I need to see SERP results from my country code TLDs (co.ke).
Due to the inefficiency of this setup, stopped using this two days ago.

- Quotes from Fiverr and Upwork were between $65-$200. Unfortunately, I cannot afford professional help at the moment.

What I am trying:

- I am using a combination of Linkclump Chrome extension+ MurGaa Recorder for Macintosh + Excel.

- Here's my present workflow using these tools: Copy paste one keyword into Google.co.ke and search >> Trigger Linkclump action (copy to clipboard) with shortcut key recorded using MurGaa recorder >> Switch windows to Excel >> Copy paste SERP links to Excel >> Repeat for the next keyword.

This process is quite inefficient but faster than the first setup.

Why I need help:

I am not coding literate hence cannot roll own solution.

I do not have the money to buy a commercial solution.

How you can help me out:

Suggesting a solution or tip. For instance, is it possible to automate my present workflow by using Mac automation scripts? Which ones?

Hope that I was not too verbose. I also do not want to come across as demanding help or free stuff. I just need help if at all possible.

Does anyone have feedback on the product itself?

I'm an old person, and still use Outlook for Mac as my main email program, though I keep webmail (Google Apps) open at all times for searching mail.

I'm still a hardcore believer in standalone desktop apps for email, and I'm not particularly excited about Outlook, and I have a busy office full of people, so this is interesting.

Is it any good? Who is it ideal for?
