Thank you for this. I grew up outside the scene but it is so encouraging to see things like this celebrated.

I just looked up Cochrane ON because I hadn't heard of it before and yeah, it seems a bit of a mystery to me why it isn't more settled. I live around Edmonton where farming is a major industry, and just for comparison:

Mean daily temperature range (min to max): Cochrane -19c to +24c, Edmonton -15 to +23

Growing season: Cochrane 155 days, Edmonton 123 days

Frost free days: Cochrane 99 days, Edmonton 135 days

Precipitation: Cochrane 90cm, Edmonton 42cm

Around the first world war when the area was being settled, wikipedia quotes "7 months of snow, two months of rain, and the rest black flies and mosquitos. If I had to describe Edmonton, it would be 6 months of winter, one month of rain (June), 2 months of mosquitos, and 10 months of sun.

If I had to guess, the frost free days is a big factor. Even though Edmonton is further north, we benefit from the jet stream coming over the mountains and largely keeping the arctic air mass away from us. The jet stream tilts further south into the US by the time you get over to Ontario so Manitoba and Northern Ontario can get some bitterly cold winds.

My armchair assessment is that both will have their uses. 80/20 is 3-4x the price, but is lighter and more rigid than EMT conduit. EMT conduit is sold everywhere and will be more useful for quick and dirty setups.

For a machine like a 3d printer, I would choose 80/20. For some lightweight shelves, EMT conduit or wood. So I see this product almost as a wood replacement rather than a 80/20 replacement.

Swimmers on edge lanes get affected more, and they leave the outside lanes unoccupied except for the first stage of qualifying.

You can't use LFP batteries as a direct replacement in your UPS, no. The voltages and charge characteristics are different. What you can do is replace the UPS with a portable battery solution, like another poster suggested. I believe the Anker units are one of the few that can function as a UPS. Most sorta-can, but the key difference most of them lack is that they don't turn on automatically after fully discharging when the mains power comes back on. It's up to you if you need this particular feature.

Will Prowse on youtube I think has some videos comparing and contrasting the different units for this purpose.

I was recently surprised how bad Google results had gotten. Way back when I used Python heavily a google search would return results from python.org. When my kids were learning python for uni I told them the python online docs were great, but my daughter disagreed. I asked her to show me what she meant and she showed me her google search - the first page of links contained no hits for python.org results. She thought python online docs were crap like geeksforgeeks. It was one of those moments when you realize the world has changed around you since the last time you looked.

Yes, this is very true. In my case, I think my weight loss from mountain biking comes from riding hills I wouldn't normally (and often pushing up hills), eating better (I'm not sitting at my desk and therefore spend less time snacking), and building leg muscle.

Running is a much quicker way to burn calories. I hate running. :)

Agreed, I just learned that the next formula for Formula E will eventually have charging stops. The spec will allow 5kwh of charge in 30 seconds, which is 10% SoC in their case. Pretty cool.

So production isn't really subsidized in the traditional sense. Producers actually pay quite a bit in royalties and taxes, and employ people, who also pay taxes. It's more about these externalities like pollution that aren't factored into the total cost of production. Alberta has oil, and when the price is high, oil producers pay top dollar for people, which sucks all the air out of the marketplace, and makes it really difficult for anyone not in oil to stay in business because their people just quit for more money. Then when the price drops, a bunch of people get laid off, some try to start businesses, and the whole cycle starts again. It's difficult to have a well-rounded economy in this situation.

I agree, there's probably a good reason I'm not dictator of Alberta. Several reasons, actually. Something something dehumanizing people something..

For context, Alberta oil sands have an energy ratio of about 4 to 1, meaning it takes one barrel of oil to produce 4 barrels. The world average is about 17 to 1 with your typical Saudi oil about 40:1. It's difficult to describe what this stuff is like if you haven't seen it. It's essentially a stiff tar that soaked into sand. One of the techniques for refining it (not sure if still used) consisted of importing good oil from the US to dilute it up to a minimum standard so it can be sold. A current technique like mentioned in the article is to heat up the formation with steam until it gets hot enough so that it starts to flow. They use natural gas to heat the steam, so it's essentially a scheme to turn natural gas into oil, but with pollution added to the mix.

What works for monitoring in other basins is obviously insufficient for the oil sands, so it's good to see the federal government funding these sorts of studies. It will likely lead to better monitoring and reporting regulations, but the Alberta government will likely scream that a Trudeau is trying to f** us over once again. The last time in the 80s was plain protectionism, while this is protectionism for a much better reason.

I love my province, but man, are we stupid sometimes.

The oil produced mostly gets shipped to the US, where we sell it at a discount because it's crappy quality. This in turns helps the US pollute more but save dollars in the process. Oil sands oil makes up about 14% of US oil consumption.

If I was dictator of Alberta, I wouldn't do anything to stop production, I would just make a law that any production energy has to come from renewable, non-carbon sources. It would generate a frenzy of research and development that hasn't been seen since the industrial revolution as people pant and salivate at all that money sitting in the ground. :)

I eventually decided I wouldn't work for oil companies any longer. If they want to do it, they'll have to do it without me. It has led me down a fun career path of working for companies I only dreamed about working for when I was in school.

http://www.45drives.com/blog/ceph/what-is-ceph-why-our-custo... is a pretty good introduction. Basically you can take off-the-shelf hardware and keep expanding your storage cluster and ceph will scale fairly linearly up through hundreds of nodes. It is seeing quite a bit of use in things like Kubernetes and OpenShift as a cheap and cheerful alternative to SANs. It is not without complexity, so if you don't know you need it, it's probably not worth the hassle.

The truth is almost stranger than fiction. They are members of a group called Dragon Sector and were brought in by the train operator after 6 of their 12 largest trains became unresponsive after having inspections done at a rail yard owned by not-the-manufacturer of the trains. The manufacturer said the trains became unresponsive because of malpractice at the train repair shop and mentioned some condition that didn't appear to be in the maintenance manual. The train operator made contact with Dragon Sector and asked for their help.

It's a wild read: https://zaufanatrzeciastrona.pl/post/o-trzech-takich-co-zhak...

It appears to be malicious code included by the manufacturer to prevent third party repair that at one point included geolocation for triggering. Given that the train operator had to reduce train schedules for this which impacted service and income, it might end up as evidence in a lawsuit against the manufacturer at some point.

Not the person you're asking, but it might also be where it is installed. The connector I looked up online is rated to +40C, and being located in direct sunlight on a hot day could derate the connector compared to a temperature controlled environment. Add in some dirt or corrosion in the connector and it will generate more heat. Like you said about buying a high quality connector, something with more margin in terms of current will help prevent problems from developing.

The electrician may have been referring to the 16 amp connector specifically being too close to the charging current.

I have heard about it, but have no opinion on if it is true or false.

It's an advantage because you as a botnet client have made the server side do extra work. You sent two packets, one to request a new connection, and a second to immediately cancel the request. The server on the other hand sees a connection request and does some work like allocating memory and fetching the resource you requested. Once the server starts sending the response back to the client via the reverse proxy, the reverse proxy notices the request is no longer current and just drops the response on the floor. As a result, you made the server do some amount of work and you don't have to worry about saturating your internet connection. They call this a magnification attack because for the cost of two requests you made the server do some multiple of work.

You could add some smarts to the server or reverse proxy that delays starting work in case a cancellation request quickly arrives. This is probably part of the mitigation work they refer to in the article.

I think you misunderstand. I don't think the parent is saying fractional scaling is better than Windows, just that it sucks less than it used to and is almost usable now.

X and Wayland has had fractional scaling for a long time, but getting apps updated to pay attention to it is moving at the speed of Open Source.

Saint Helena has import tariffs like other colonies do. They used to have preferential rates for commonwealth countries but I'm not sure if that still exists. I guess my response would be they have import duties for the same reasons other colonies do. Why wouldn't they tax imports?

edit: found an updated tariff document https://www.sainthelena.gov.sh/wp-content/uploads/2022/08/ST... . I don't see anything special for commonwealth countries so it's probably a thing of the past.

I've also found Ikea knives to hold an edge as long as my Victorinox knife. They are only stainless, but the alloy they use seems to work quite well.

No, migrating did involve intervention from the account holder. More information here: https://aws.amazon.com/blogs/aws/ec2-classic-is-retiring-her...

It seems like AWS spent time, people and money to migrate customers off EC2 classic. They made a fairly good effort to automate the process and make it less painful for customers. For example: https://repost.aws/knowledge-center/ssm-migrate-ec2classic-v...

The original network was from an everyone-on-the-same-subnet model to a you get your own subnet, so yes, customer applications could break in the process. People do all sorts of non-smart things for good reasons, like hardcoding an ip address in /etc/hosts when a nameserver is down. And then they forget to change it back. To do these sorts of migrations well requires a sort of stick and carrot approach. The stick, which is we want to shut down this service and will eventually refuse you service, and the carrot, which includes automation, reminders that people need maintenance windows for their applications, clear directions, and above all, willingness to deal with people and actually talk to them.

Had a chuckle at this excerpt:

"The guests feel struck with awe in that dining-room, and solemnly bolt their food as quickly as they can. You hear less noise in an American hotel dining-room containing five hundred people, than you do at a French table d’hôte accommodating fifty people, at a German one containing a dozen guests, or at a table where two Italians are dining tête-à-tête."

The author clearly has a ranking of how much each nationality speaks while eating :)

I currently work nights in the same timezone as dang. It should happen fairly soon, but normal people are just rolling out of bed right about now.

In retrospect you could say yes, but it was hard to tell. It ended up being either okay or not okay depending on Intel vs AMD and clock speed.

It should be fine to try. Some devices dual purpose the 120 volt transformer to both charge the battery and provide 120 VAC, but those have internal switching so the 120 VAC will simply not work when charging. Given that your device charges using a wall wart, it won't be this type of device because the charging transformer is built into the wall wart. Having a lead-acid battery the charge from the wall wart likely goes to a common power rail that connects to both the battery and the inverter. About the only bad thing that could happen is that a crappy wall wart might try to supply too much power and overheat. I would check if the wall wart is getting excessively hot when running your test.

Also, I took a look at the user manual for the device and it doesn't mention not to try what you are thinking, so it should be fine.

Eric O from the South Main Auto youtube channel has some great videos on tracking down parasitic drains on modern-ish cars. From his videos I learned that often cars won't fully sleep for up to 45 minutes depending on the model and manufacturer, as well as checking for the voltage drop across fuses to figure out which circuit is draining the battery. With this I was able to track down a parasitic drain in my 2000 Beetle (failing door lock). I'm sure he mentioned other tips as well but those are the ones that stick out to me.

Similarly the authors talk about how the multiline brackets were hand-drawn, and how could they be that precise? They might now know how common engineering stencils were for such things. Just find the bracket of the right size, and trace it onto the page.

It's going back a few years now but the gnome 3 debacle is a reasonable example of not respecting users https://felipec.wordpress.com/2013/06/12/the-problem-with-gn... . I think in subsequent years the devs have been worn down and the community solved the missing features in other ways, but some people have long memories. gnome 3 is the primary reason Ubuntu got its own desktop system, it was that divisive.

The Steam Deck is uniquely positioned to allow people to do potentially hazardous things like install software from unknown sources, and that is because it's primarily a gaming device. People aren't doing banking and work stuff on it, so what is the damage if it gets rooted? Valve could have easily screwed it up by building a walled garden anyways, just to satisfy corporate greed in the name of "maximizing ROI". Sony, Microsoft and Nintendo all have their walled gardens for gaming. The fact Valve hasn't (yet) is refreshing.

I have one of the cheap calipers that needs new batteries every 3 months. It both sucks and is surprisingly useful for stuff around the house. I ended up buying a 20 pack of batteries and leave them sitting in the same drawer as the calipers so they're at hand when the current batteries inevitably die. The Mitutoyo's are definitely a better tool.

I tried to use Bose QC's at home for a few years but eventually gave up. The problem with Bose is they noise cancel everything but voice, which is precisely the opposite of what I want cancelled. I like hearing footsteps, pets and all the normal noises of the house but I don't want to hear my wife gossiping on the phone about so-and-so's parents at the school and their messy divorce.

Bose QC are specifically targeted at air travel where you can noise cancel the airplane noise but still talk to the stewardess or your neighbor. I found a no-name brand of noise canceling headphones off Amazon a much better solution because they had better ear pads that isolated sound while their worse noise canceling didn't give you the same "pressure" feeling that the Bose headphones give you. And they dulled the voice chatter more effectively. It seems like if voice chatter doesn't have the high frequency component it is easier for me to ignore it. I think it's also why I find it next to impossible to pay attention to someone dialed into an online meeting.

Eventually circumstances allowed me to buy nicer homes with dedicated office space and I find I don't use noise canceling devices any longer. My current home is an executive-style-home-on-the-cheap and has noise isolating insulation in interior walls which really helps.

What is strange is that the emotion present in the voice chatter around me is a huge factor. My son can be gaming in the office with me and talking with his friends and I have no problem with focus. If he gets frustrated or too hyped up, I have no hope of concentrating and I have to kick him out of the room. We have since worked out an agreement and he doesn't play LoL or Destiny while I am working, the two games that cause anger management issues for him. :)

Ah, thank you. I didn't know what the difference was between a smelter and a foundry.

Yeah, I'm not sure about that unavailable at almost any price part. If you could put in an order for a million tons of steel you would get on the steel manufacturers order list, which is what I was thinking about when I mentioned almost any price. But it sounds like they have been working through their existing material for decades and are only now running out. The material may have last been produced a long time ago so the quantities they need are very small. That 50 tons of scrap may last them for another decade or two.
