It amazes me that Machine Learning is all many people think of when they hear AI. Machine Learning (ML) is a subset of AI. You can also hear about Deep Learning (DL), a subset of ML where you have multiple layers/multiple models. There's a decent Quora thread on Deep Learning vs. Machine Learning [1].

Both ML and DL require a fair bit of data to do their training. There are some techniques to reduce training data, such as a Generative Adversarial Network (GAN) pitting an AI that generates data (some supposed to be fake and some legitimate) against an AI that tries to determine which of that data is legitimate.

However, ML and DL are not the only way to apply AI. There are a great many solutions you can solve with one or a combo of:

* Genetic Algorithms [2]

* Bayesian Inferencing [3]

* Semantic Reasoning using rules, and possibly using ontologies [4]

In some cases the approach might not generate a solution as good as from an ML-approach, but it also won't require the same level of data either.

Btw, semantic reasoning has a similar problem. Just like ML requires data, semantic reasoning requires an rules and/or an ontology, and creating a good ontology while avoiding the pitfalls is an art form.

For example: If I asked you to create classes for an ontology of vehicles, you might be fine with sea_vehicle, air_vehicle, and land_vehicle. But that's not going to work well. What about a submarine? What about an amphibious vehicle?

Instead, we can define the classes vehicle, movement_medium, as well as verbs moves_on, and moves_through. Now, a ship is a vehicle that moves_on the movement_medium water. A submarine though is a vehicle that moves_through and moves_on water. Both our sea_vehicles. Getting the ontology right is often one of the hardest aspects of applying semantic reasoning.

I recently had a great ML approach mapped out to solve a problem for a client, discovered the client hadn't kept the data they had gathered in a machine readable form (it was in notebooks and scattered PowerPoint decks), and we pivoted to using a Genetic Algorithms approach.

I do, but these are more complex things where they actually add some type of value (even if it's "this is safe to use because it will be around forever since this big company has vested a lot into it"). But cue is a config language which in itself is a niche area. Also, it is much simpler to rewrite configs from one language to the other, so it's safer to choose the "weird" one.

Liberal Democrat’s.

They’ve been thrown under the bus for entering a coalition government and choosing to support alternative voting over scrapping tuition fees.

Since they were a minority player they didn’t have much choice in fighting that ultimatum, but I understand why people feel scorned. Even if the conservatives are doing many, many more heinous things daily.

As a nice conincidence the “NoToAV” campaign (lit. “No alternative vote”) was undertaken by the same people who drove the leaveEU campaign, they used remarkably similar tactics too. “AV will cost £250m, that should fund our army!” And such.

I mention it because it was funded by the same conservative doners. So the Lib Dem’s lost both ways.

Something I'm planning on doing at some point, is to make a frame to attach the back seat of my Jeep on, to turn it into a "couch". It would be great for camping, or in the garage.

There was a company that sold a frame for doing just that, but they went out of business. Fortunately, you can still easily get all the attachment points/latches and such, and welding up some simple legs and whatnot isn't that hard.

I'm going to say it's completely opposite. I worked for a video chat company and the company was dramatically more productive on the whole when we had a substantial remote contingent. We were forced to use our product on the regular and understood our use case. When the company moved to consolidate, productivity suffered.

Why consolidate, then? Mostly for the advantage of the people whose jobs were social. I don't think it was malicious, but I also don't think it was what was best for the company.

Sustainable forestry is not a particularly complicated business, and if you are selling the wood for buildings etc. the carbon is not released back into the atmosphere for quite some time.

A lot of jurisdictions are looking at updating building codes so you can use treated wood for larger construction projects. If this was done in a number of large markets, it could reduce demand for concrete, which is the number two contributor to GHG emissions.

To GraphQL there is also the opposite: Just move as much stuff as possible to the backend - make the frontend thin.

With that approach you also don't end up writing a lot of specialized REST endpoints for the frontend.
You can just use the queries directly and output for example HTML (or json and render that into HTML on the client). You can also do a lot more queries at once, because the services backend have usually more bandwidth and less connection limits than a frontend running inside a browser.

You are full control of the queries. Only UI related data is exposed to the frontend.

One draw back is the frontend team wouldn't do any business stuff anymore. They would do more generic components that the backend can drive.

And depending on the implementation you need more server round trips.

On the other hand, there is less JS to load and execute by the browser, since the backend is doing most of the orchestration and rendering.

Nterview with PINE64 on the Upcoming Release of the PineBook Pro
I live in a pretty hot city (My car's outside thermometer showed 48°C yesterday at midday).

The extended range is nice and all, but if somebody makes a car that can run the AC without running/draining the battery while it's parked, even if it's just a little to keep the car interior at 35°C or so, I would, without exaggeration, buy it the day it's released here. Hell, I'd consider it even if it would just keep the fans on to vent the hot air out.

Parking in the sun while doing errands, which often involve multiple short trips where the car's AC doesn't get enough time to cool it down, seems to be a very common cause of heat-stroke among white-collar workers here. I've had to go to the ER twice about it this summer alone.
Interesting! What's interesting to me as well, is that despite their criticism, both scientists do seem to support the opinion that it is an extremely important measure to add to our portfolio of climate measures.

>>For CPU intensive tasks, performance _is_ close to Ruby, while both Ruby and Elixir are far behind Go.

Yeah, but how many companies do you know of that perform heavy computations in such large scale that their choice of programming language has a noticeable effect on the result?

I mean, it might matter for tech giants like Google, who need to squeeze every bit of processing power out of their CPUs. For almost everyone else, it will be a non-issue.
how much power does an AC use (say on medium settings) ?

I'm not sure Walmart really needs "millions" more products. Amazon's largest problem are low grade, poor quality goods and actually being able to choose between them all. If Walmart can cover a significant number of categories with a couple of known and quality options, they can definitely make inroads.

Walmart also has a huge network of actual stores, and I've ordered more than once for delivery at a store. The bigger issue is mindshare and branding. I often don't think to look for something at Walmart and it's often only in frustration of Amazon's abundance of choice or other issues I'll think of Walmart.

Beyond this, there are lots of other things that are just there at Walmart, and often don't need delivery to me, the store is enough. Walmart, iirc, covers something like 85% of the U.S. population with a store within 5 miles. That shouldn't be underestimated.
Does the math check out? You would need about 10kW-h to get the claimed distance, times three for the efficiency (by the way, there are NO mass-produced cells with 34% efficiency; they must be using GaAs or multijunction cells to achieve 34%) means solar input of 30kW-h per day. The projected horizontal area of a Prius is 8m^2 (including the windows) so we need about 4 hours of 1000W/m^2 insolation. Which I guess isn't totally impossible. Typical average insolation at populous latitudes is around 200W/m^2.

We create these systems to be of use to humans. When they aren't of use to humans, that's a bug, and is viewed as something to fix, so we convene humans to provide a fix, whether for a specific case or to the system overall.

Ultimately, the only ways that situation doesn't play out is if the system is designed perfectly not just for current use but all future uses, or Humans are removed entirely from the equation. Since the former is impossible, and the latter means the system is either irrelevant or we're all dead and gone, we might as well accept Human intervention as inevitable.
It would also be cool, pun intended, to add windows with liquid crystals that can darken when parked to keep additional heat out.

Keep in mind that this article is specifically discussing defaults, though, not necessarily the overall potential for security hardening. There are certainly some security-related features FreeBSD is missing when compared to other BSDs (OpenBSD) or Linux distributions, but some of what is called out can absolutely be accomplished by system administrators after installation, or as part of image deployment… but it would be better if the defaults evolved to be more secure without extra configuration.

As general purpose operating systems go, there was another interesting article from earlier this year comparing popular Linux distros which found that Ubuntu (18.04) had the best overall posture with regard to use of hardening and mitigation mechanisms out-of-the-box vs. versions of CentOS/RHEL, Debian, and OpenSUSE at the time. Some of this was due to the newer Linux kernel version being used, but also thanks to hardening of binaries, etc.

> Our experiments indicate that Ubuntu 18.04 shows the largest adoption of OS and application-level mitigations, followed by Debian 9.

Rumour now has it that Apple will make the almost unprecedented move of abandoning this keyboard design [1]. Technically, they might be replacing it with a newer design (vs the old chiclet keys which IMHO were actually great) but still...

One can't help but note the timing of Johnny Ive leaving with this move. If it comes to pass (and it is just a rumour at this point and there are a lot of false Apple rumours because clickbait).

Johnny Ive does seem to be obsessed with thinness to the point of ludicrousness. It's said design is the art of compromise and any design is a compromise. To me the 2010+ Macbook Air was essentially a "perfect" laptop. Powerful enough, with enough ports but also quite cheap (under $1500) and light. Size, weight, cost and power are all axes for compromise. This was largely replaced with the 12" Macbook, which sacrificed pretty much everything to shave off another millimeter or two. One USB-C port.

It's almost unprecedented that this form factor (13" Macbook Air) would be resurrected yet it was. Is this tantamount to an admission of error with the 12" Macbook? Was it effectively a rebuke of Johnny Ive's "thinness above all else" philosophy? Is the new keyboard (if it happens) a furhter admission of error?

I don't know of course but I'm hopeful that the current trend of terrible Apple design will reverse.
