Ask HN: How to learn to sell professional services as an engineer?
I would like to understand the sales process better and learn how to actually sell professional services (consulting) in a B2B context.

I want to learn how you identify relevant companies, introduce yourself to them, convince them to give you the opportunity to present yourself and your services, convince them to hire you for a project etc. ?

Any recommendations on how to learn this would be much appreciated.
(A) Frame the full picture in your mind before you start to write [1, 2]. A short story: Someone once wrote a long letter to a friend, and finished it with something like "Sorry, I did not have the time to write a shorter one!" [3] I.e., it can take longer to write shorter! The reversal comes from conceptualization and framing of what you want to say, not from the actual writing itself. Use mind maps for this if that would help.

(B) Be conscious of word choice. Check even those words out in a dictionary which you think you already understand. You may soon have a refined judgment on when to check.

(C) Introduce time breaks before reading your creation for self reviews. Writing involves intense thinking which is a subject to confirmation bias. Reading your own writing a few days later will give you a flavor of what it feels like as a reader.

(D) Close the feedback loop with the actual readers, whether live or offline. Watch for the discussions that happen on the subject and see if those discussions could have been avoided by writing differently, thereby driving consensus faster.

>> which of my edited drafts should I choose as final version.

Why not have only one draft, a single working copy of the doc? :-)

Ansible-NAS: An Open Source Home Server Solution (2019)
You seem to be describing p-zombies which (IMO) don't have much overlap with present day science. Higher level reasoning would appear to increase fitness in many cases. For whatever reason, our version of it appears to involve conscious introspection.

As to the point of the article - it's about modeling human learning as a reinforcement learning problem and thus pain as one of many interacting loss functions. In particular it's about modeling how these different loss functions interact with one another to achieve a desirable outcome.
Skeuomorphism is more than just aesthetically resembling real world objects, it’s an imitation of the behavior of real world objects. Think a digital book that duplicates the way you interact with a book, not just using fancy page turning animations, but demanding that this be the way in which you go to the next page.

The advantage software has over real physical objects is that it need not duplicate the limitations of a real world object. A software book can jump to the next page instantaneously, and index your notations, and provide instant dictionary lookups. More importantly, it can’t duplicate precisely any of the real advantages of holding and interacting with a book because you’re not interacting with a book, you’re interacting with a program through a proxy device (a mouse, a trackpad, a keyboard, a screen, a d-pad, whatever).

The skeuomorphic aesthetic was ugly in the eyes of many including my own, but there was an argument to be made that instead of taking advantage of the fact that this is software, Apple was leaning too hard on the skeuomorphic design trend in terms of how their applications behaved. The two most egregious examples were Notes and Newsstand, the Notes app tried to duplicate a memo pad and the only typeface was Marker Felt in a single style (to imitate handwriting) and Newsstand behaved almost exactly like a Newsstand you might find in a bookstore, holding magazines and offering them for sale. The magazine apps usually tried to duplicate the look and feel of an actual magazine, but with the addition of audio and video.

Now the Newsstand is gone, you can still get magazines, but through News or the App Store a lot of publishers caught on that duplicating the look and feel of actual magazines probably doesn’t make their product more appealing. Notes is a much more powerful tool than it used to be and if it were your only Notes app, it isn’t a bad one to have and supports actual handwriting input if you so desire.

That said I will say throwing out skeuomorphism didn’t have to mean throwing out depth and detail, but when Ive’s team took over software design, they imposed their own vision and that vision went too far into minimalism, foregoing detail for slight and subtle contextual clues that could be missed, and then further refined from there into something a bit more usable. Thinking about it, I don’t really have a problem with how it stands in iOS 13, although iPad OS 13 needs to fix its interaction paradigm.
Any load balancer will let you do that. Scaling is a few lines of scripts to do on any platform, and well worth the couple minutes, you don't even need a tool for just that.

No tool "works the rest out". It's _always_ a compromise, because inherent complexity can never be removed, only moved. What you gain in one area, encumbers another.

You may freely use k8s, but it's not magical nor easier to use than any existing systems. In fact adopting it often takes non-trivial time and the web is full of failure stories with very benign warnings and catastropic results.

Total Enhance RX Custmer Reviews
Imprint Knott, 45 years – I was unable to bear to have a pleasuring room meeting with my companion and he was additionally exceptionally baffled by this. I have not had the option to keep up my erection for quite a while period and this is the explanation that we both are not understood. One of my companions recommended me to utilize a Total of Enhance RX Testosterone Booster. Without intuition much, I book this item rapidly and this is the thing that produces viable outcomes too.

Presently I give my significant other the most elevated measure of fun and this item is has gotten satisfaction our lives once more. It is enthusiastically prescribed to utilize routinely and it won't give any symptoms. The outcomes that can emerge out of this item will be simply fascinating and you should attempt it.

> Is anyone using it outside Perl?

I first saw it used with JavaScript, so I assume yes; but the site itself answers this, too. (specifically the producers and consumers pages.)

I think it is of limited use if you can use any of the more sophisticated defacto standards like JUnit compatible output. Still, you can imagine scenarios where a stupidly simple test protocol would be nice. One fairly esoteric use case might be test ROMs for CPU emulators; today many of them output results to serial in some format, but AFAIK there is no unification of the format at all, across different test ROMs.
As long as we rely on languages like C for our foundations, we will have them, just not always on TLS, that is why it is so relevant to push for better foundations, even when most of us aren't doing systems programming.
Software developer here. I work about 6 hours concentrated on stuff before i notice a drop in cognitive abilities. That's not counting the short breaks for toilet, getting coffee etc... Then it's roundabout 5-5:20 hours.
These breaks normally don't get me off the topic very much as i can continue thinking about what to do next or crunching on a solution.

But after that time I start to mix things up and make mistakes. So I really wish 6 hours were the actual work time... but in reality I have to work 8 hours a day.

Well, you need to pay for updates, but even that is inaccurate. Before JDK 9, Java used to have major releases, now it doesn't, and the version name is incremented every six months even though the changes are small. So instead of a major release, that's supported for some years, there's now a steady stream of small, gradual change with free perpetual support. There's also an alternative new, non-gradual upgrade model, and if companies want to use it, they need to pay.

Reddit is a cesspool.
I misspoke in my last comment when I referred to space and time complexity. The usual problem in the field isn't figuring out the big O characteristics, it's unpredictable performance due to evaluation of an expression building up a huge chain of thunks. Because of the inherently non-local logic of lazy evaluation (or, whatever evaluation strategy compatible with non-strict semantics that GHC actually chooses to use), it is not always easy to find which piece of code is introducing unwanted laziness.

That said, it's the same fundamental non-locality that also makes it more difficult to figure out the big O complexity of an algorithm implemented in a non-strict language.

Quite frankly a lot more than this. The reason is that at the end of the day I need to be productive. While I viciously oppose this sort of stuff, I've turned off enough of it not to be bothersome and what is left is an extremely reliable, flexible and easy to drive operating system.

I am a very experienced Linux user both on desktop and server side of things. In fact 90% of what I do targets Linux but all the desktop solutions are quite frankly a mess. After 20 years of infighting and rewriting the universe, there is no cohesive desktop that even makes any sense at all and isn't bug ridden. I am forever fighting small things and edge cases to get anything working. Within a few days, it gets toasted and back to windows. I don't have enough hours left before I'm dead to actually argue with these things.

And as for MacOS, the hardware went down the toilet, you tend to have to fight the OS at every available opportunity, the pricing is quite frankly terrible and it's utterly inflexible. It's Apple's way or a punch in the balls. No thanks. At best I'm hanging on lightly to iOS as that's not too problematic when it's being inflexible (apart from HEIC which is a pain in the ass)

I also beg people to find a better place where I can throw together an 8-core workstation class machine with 32Gb of RAM, 4k 27" display, decent GPU, replaceable NVMe storage and high quality input devices for < £1300 that actually works reliably and the software doesn't get in the way.

Gocryptfs has a comparison of these projets, here [2].

Focused on Windows only, to my experience, securefs is the one that is working the best as it is not using dokany but winfsp (FUSE for Windows). With all other solutions using dokany, the copy or sync of large number of files is damn slow or hanging.

We build quite the "contraception" for circuit board mounting anything not compatible with reflow soldering. It mostly works but the women that do it usually are just way faster and less error prone.

We have quite the high wage standard and even then the device is mostly used to show off.

Real automation is probably needed in bureaucratic workflows even if we usually think about manufacturing. There are probably advantages and disadvantages here as well.

Since order situation is great at my current company (strangely the covid-quarter was particularly good), we have significantly expanded workforce in production.

I doubt that unions really drove automation in my country though. Price plays a role but also technological feasibility.

Is it legal to test someone without their knowledge or consent? Like if I MITM the public toilet and start drug testing random passersby... well the results would probably be skewed due to contamination... Now that I think about it, this kind of massive, drive-by poo-veillance is actually a really hard problem.

Wait I'm getting distracted. Yeah, original question: is consent needed before such testing can be done? Mileage varies by state maybe?
That's what the media has been screaming all these years. The reality is often that the 10th person has their role change, they retire off or (as in the case of the engraving industry), people end up buying more at a cheaper price.

When the benefit of doing so is greater than the cost of switching.

All things automation. Really a chainsaw is automation, and so is a compressor. Automation is a pen. They all remove work and increase efficiency.

There are lots of examples which don't really count though, such as self-checkout, which have exactly the same amount of work left, only who works it is a different person.

Kathy Sullivan is my heroine. Her first spacewalk was one of the most dangerous spacewalks ever attempted, as they tried to demonstrate the Orbital Refueling System (ORS) capability of the Space Shuttle.

It would work as follows, an astronaut would manually capture a satellite with the help of the Shuttle's arm, and then they would move it into the bay where they would refuel it with a hypergolic mixture that included hydrazine. At the time, the odds for a fatal interaction with the hydrazine were rated low, but in retrospect, this manoeuvre was extremely dangerous and incredibly unwise.

The details of the experiment involved them doing an EVA and then servicing the satellite and hooking it up with the fuel source, before retreating to the shuttle to let the hypergolics flow. It is needless to say that a mistake would have been costly. AFAICT, the project was never attempted again and was cancelled after the loss of Challenger.

Straight up, what's people's views on all this big data stuff? I see it in so many job ads and I really can't believe it's necessary. Sure, at the far end of one side of the bell curve are companies like uber but otherwise, are people using it to process a few terabytes that could be done better on one multicore server? How many companies have enough data to justify it? Personal opinions welcome.
I think it's actually a bit more complicated than that because we're talking about Java SE, which is in the excepted list. On Intel/AMD, every core is counted as 0.5 "processor units" (http://www.oracle.com/us/corporate/contracts/processor-core-...) so the unit "processor" price is per 2 cores.

But whatever the definition of a processor unit is, it didn't change. The prices both before and after the change are for the same unit.
These seem to be specifically CO2 emissions from coal. When you look at total CO2 from all energy sources Poland fares better also than UK or Czechia I think.

Help me with ideas to monetize my $10k DigitalOcean free credits

How can I use the credits to quickly raise funds that can enable me work on my project.
Thermal engineer here. There absolutely no need to use fan cooling, humongous heatsinks or harebrained temperature controller schemes to cool the raspberry pi 4.

All that is needed is a small heatsink to slightly decrease the thermal resistance to ambient air, to stay below the thermal throttling threshold.

Anything more complicated than that is a pointless exercise in pointlessness.
This was requested before and there even was work on a prototype that has since stalled. If you (or anyone else) is interested, please check out https://github.com/mre/tinysearch/pull/37. Maybe we can get this done in a future version. :)

There were a few pre-installed apps but that's completely normal to be honest. If you go in a shop and buy a PC then it's usually full of that shit. If you remove it, it doesn't come back. They're not really ads but things the average user will want (I want office!!!)
You can still acknowledge interrupts in between, so hardware watchdogs will prevent this.
I kind of agree. I think in most situations, a Pi is going to sit idle most of the time, so it won't need active cooling.

I'm surprised not to see more people adding their favorite movies. Just sticking to things semi-related. I may have to go watch "My Man Godfrey" again but at least for me "The Thin Man" and its 5 sequels stuck with me where as though I watched "My Man Godfrey" years ago but I don't remember any details of it. (same lead actor and he pretty much always plays the same type of person)

"The Man Who Shot Liberty Valance" is a good movie but if you want some other westerns starting James Stewart I can recommend "Destry Rides Again" which is not super serious but I found it throughly entertaining. Also "Broken Arrow" (1950), (not the 90s John Woo movie which is a fun popcorn movie).

Seeing "The Good, the Bad, and the Ugly" on the list I recently saw "The Outlaw Josey Wales" which I enjoyed (also a Western with Clint Eastwood)

Of the movies on that list I've seen the one I'd recommend the most is "Women in the Dunes". I don't want to over hype it I've seen most of the movies on the list and they are all great stories but "Woman in the Dunes" might give you something new to think about where as the others are mostly just great entertainment.
