Keeping them within a certain range is useful but not as much as preventing them from overheating, heat and fast charging is more dangerous, basically if you limit them to 80% it will prevent trickle charging, you can do this in hardware by monitoring the speed it charges at and shutting off when it lowers with wattage monitoring equipment. Apple has this as well, and every lithium charger has trickle charging at 80%, but not all of them are able to end charging at this percentage.

By hack I mean a bypass versus your meaning of attacking the security and removing DRM, is there a reason you can't just use another chip or anything special its doing? Do you need the CPU and is the cryptography documented enough to make it easy or woth the effort? It may also be a passion project so I understand if you just want to do it to do it, and even share the information. If it is battery charging features if they're important are not special. The last 20% makes extra cycles and is the most stressful.

>Turn off the device or disconnect the load on charge to allow the current to drop unhindered during saturation. A parasitic load confuses the charger.

>Charge at a moderate temperature. Do not charge at freezing temperature. (See BU-410: Charging at High and Low Temperatures)

>Lithium-ion does not need to be fully charged; a partial charge is better.
Not all chargers apply a full topping charge and the battery may not be fully charged when the “ready” signal appears; a 100 percent charge on a fuel gauge may be a lie.

>Discontinue using charger and/or battery if the battery gets excessively warm.

>Apply some charge to an empty battery before storing (40–50 percent SoC is ideal). (See BU-702: How to Store Batteries.)
If you’re comparing Cleese not attending a talk to protest people not liking his jokes, to a monk self-immolating to protest genocide, then maybe you need to reset your perspective a bit.
Nah, they were pretty crazy in the 1960s and 1970s too. Some students went as far as promising to take up NVA arms in protest of the Vietnam war, an obvious farce.

These things come and go in waves, and people have short memories.
To be clear, he did that and then had his manager blacklist the two women who spoke up about it. It’s not just the act, it’s the cover up that makes it particularly heinous.
The batteries would then need to be more easily accessible and a more standard shape. You probably couldn't have batteries in the wings.

I would imagine commercial planes would take a hybrid approach. They would have their own primary batteries hidden throughout the plane, and then they would have range extender swappable batteries in the cargo area.
I can't think of a better way to make FB's vison for Meta sound even more boring, corny, soulless, and ugly than it already does than by implying you see Disney as the gold standard of anything content-related. Disney is like,...the concentrated essence of the worst of American content culture

That's because the Byte issue was the "coming out" for Smalltalk -- a description of their work but not necessarily new work. Bitblt was first implemented in Smalltalk-74 I believe (meaning ~1974)
>Should we try to identify "good" reviewers?

To this day I don't understand how the original Netflix algorithm for predicting user desires isn't co-opted for everything.

I don't mind people rating taco bell 5 stars. I just don't want any of their reviews influencing the restaurant ratings I see.

Same with basically every product category. We have this insanely intricate and rich data set that could truly help people find things that are great for them. But it's all locked away and only used for making a buck with nobody giving a shit about making people's lives better.
One aspect that you might want to consider is not to ask "why am I wasting my time" but "why am I not in control over how I waste my time". Or maybe "why I'm not happy with how I waste my time". Or, even less judgmental: "Why I'm not happy with how I spend my free time". If you look at the comments here, most people who don't have this problem just don't get it. "Just be less judgmental with yourself." But it's not about that, is it?

When you watch something like "The Bachelor" every day together with your girlfriend, some might consider that wasting time. And maybe it is, but I wouldn't consider it problematic. It's limited to one episode per day. And when you're watching it with someone else there's a social aspect to it. Ultimately it might not be valuable. It won't make you smarter, hustle harder, or improve your life. It's not a worthwhile endeavor. But I still wouldn't consider it problematic.

So that's one hypothetical situation. Another is when you open up Reddit because... well, that's what you always do while eating. And then keep scrolling /r/all for three or six hours, and go to bed at 3. What I consider problematic here is that the decision of what I feed my brain is deferred to a website. And that sometimes I have a hard time willing myself to stop.

So I don't think it should be about wasting time, because that derails the discussion into what is considered a waste of time and what isn't. That's a question everybody should find their own answers to. The issue is that you're not happy with how you spend your time. It becomes problematic once you can't control your usage, can't stop once you start using, and feel like you're no longer in control over what you're watching.

Thank you for posting by the way.
Corona beer also. Who wants to down some Corona after all this?
Because models <> reality.

That’s it. Full stop. Anyone who thinks otherwise will eventually face this same fate.

For instance, from the sub-heading, “But the pandemic messed up its predictions”

should really be this instead, “but their algorithms couldn’t handle a situation they didn’t anticipate”.
> Peter Jackson pored over nearly 60 hours of footage for his documentary “Get Back.”

I thought that might be a mistake. But then it was said again in the article. It’s really not a lot - by our standards today. But then considered that, IDK, for 1969 this might be more then it seems.
In addition to calling my question 'wrong' - can you also answer it?

Also, if your 'correct' metric were right, then everyone would walk. Does that solve the problems flying does? I don't think so.

[edit]: Also, I guess your metric explains why everyone is only taking the bus or train, and private transportation does not exist?
"Do your own research" is disingenuous. If I do my own research (and I have) and it disagrees with your beliefs, you'll still tell me I'm wrong.

Incidentally, people thinking for themselves and being able to look at studies and talk to (actual) experts directly without the interference of the media or "experts" is exactly why there are so many skeptics, and why the White House, the Media, and Big Tech are doing everything they can to censor the living shit out of vaccine discussion. You people spent years yammering about how great the free, uncensored discussion on the Internet would be: finally the strongest ideas would win out! And then when people didn't come flooding to YOUR ideas, but actually started to move AWAY from them, you screamed for it to all be shut down, post-haste. The game is only good when you win, huh?
yeah, don’t do that.

We can choose to not be shitty.
Students at UC Berkeley have been accusing people of being far-right reactionaries for longer than I’ve been alive. They’ve always been seen as extremist. Maybe it’s just the student protests in the 1960s succeeded in completely changing the political landscape.

But the idea that 1960s UC Berkeley was not “extreme” is ahistorical. Hell, UC Berkeley protests have their own Wikipedia page, just for the 1960s:

https://en.wikipedia.org/wiki/1960s_Berkeley_protests
If it's funny, then that's something. If not, critics gonna critique.
Great points. I mentioned this in another comment but it’s worth adding that the Right does this too. Like adults in the 70’s and 80’s trying to cancel heavy metal bands and get dungeons and dragons banned because it was “satanic” and would corrupt the youth. Ridiculous stuff, but similar behavior from a different political faction.

It sounds like he has gone through an iterative process with them: they offer some objection to vaccination, he provides a refutation of that objection, they switch to a different objection, repeat. And it sounds like as this loop repeats they are turning to increasingly bogus conspiracy theories for new objections.

Based on what I've seen from social media that kind of person usually doesn't just reject COVID vaccination. They usually seem to also reject masking, social distancing, avoiding crowds, and often just assume that it must just be a cold when they do get sick and so don't get tested and don't take much care to not expose others.

If he's dealing with that kind of family member, keeping his kid away from them until the pandemic is over is not unreasonable.
I recall that in either gdb or Qt Creator's gdb wrapper, parameters were sometimes being uninitialized when I breakpoint the function declaration line, then be initialized when I single-step to on/before the first line of code. I can't replicate it now though.

I'm interested in the promise of omniscient debugging to partially replace both debuggers, tracing tools, and logging (including printf debugging), for bugs in complex systems which you can reproduce in controlled environments (not in production). However I don't believe it will be perfect even there, because I've noticed that when debugging many binaries (especially non-symboled or worse-yet stripped ones) in gdb, it prints many variable values as "optimized out". This requires special debug builds which partly alleviates the problem (I still get better results with compiled-in debug prints).

I've recently been tracing the execution of the pipewire daemon. Since it's a large library filled with virtual function calls constructed from C macros, it's painful to statically analyze by reading the code. I found a Callgrind profiling trace to be useful as a control flow analysis tool. Unlike perf, it logs every function called, counts the calls to each function, records all callers and how many times each caller called a function, and even records how many times each line of code calls another function (can distinguish between two calls to the same child in the same function).

For example, I recently used KCacheGrind to identify that spa_alsa_open() was called 6 times, 4 times by one caller and once each by 2 other callers. And it returned early twice, and continued onto snd_pcm_open() 4 times.

I also wanted to trace all ALSA functions being called across the trace (ltrace didn't work well since libasound.so.2 was loaded via dlopen, and I couldn't figure out how to make ltrace not burn CPU intercepting calls from one .so function to another). This was difficult to extract from the the Callgrind trace, and I had to rig together a script using `gprof2dot --format=callgrind -n 0 -e 0`, rg to convert the output XML file into a CSV of callers and callees, and csvsql to isolate all calls from non-snd-containing functions into snd-containing functions, so I could read the source code to see where these ALSA functions were being called. The result didn't tell me the order or parameters of the function calls, so I had to infer the order in some cases, and insert logging statements in other cases.

I think Pernosco is promising in this area, but I haven't tried it yet because it's commercial and has limited free uploads. One idea (I don't know if it's implemented or not) is having the ability to run SQL-like queries to list all calls from one binary to another .so library. Another idea (on top of the caller-callee lists you already have) is creating control flow graphs like KCacheGrind.
I’m 39. My Roth IRA recently passed $1M mostly because of a buy and hold tqqq strategy beginning in 2014. The only time I sold was in Feb 2020 just before COVID and rebought in May of 2020 for the wild ride up.

High risk. High reward. I’m normally a very down the fairway Full market etf investor. But with the Roth i wanted to take a bit of a gamble. And it’s paid off.

That said, the possibility of an XIV moment is very real. Not for the faint of heart by any means.
Well, as usual, you probably know more than I do about what I'm writing about. Am I overlooking something significant? I don't even know if you can use the Tollens test to silver copper.
If by "successfully cancelled" you mean "disappeared" or "eradicated" the answer is no. If you mean "lost gigs", "no longer welcome in certain locations", "lost income" or "forced to find another line of business" the answer is very much "yes". So-called "cancel culture" - another term would be weaponised political correctness - has had a deleterious effect on comedy by laying minefields around many areas which used to be available for comedians. Step on a mine and "boom", the mob comes out in force. While big names - Chapelle, Cleese, Rogan - have enough clout to survive this is not true for up-and-coming or beginning comedians. They can no longer expect to have the same freedom the court jesters of old had, they are no longer free to point out the king is indeed not wearing any clothes. In short, they are no longer free to sharpen their skills without being shouted down - not for bad comedy but for violating some shifting narrative. The net effect will be a dearth of comedians and comedy, a void which will be filled by "comedians" who follow the narrative and as such are anything but funny.

Let's hope the tide turns and that it turns fast.

Well, I went through 5 years of electrical engineering which is almost entirely in the realm of complex numbers and I’m struggling to convey my intuition here to you.

I think it’s helpful to understand that complex numbers are two dimensional but they aren’t like an [x,y] where the two dimensions are completely 100% unrelated.

Here’s another way to think about it in a way that is familiar to you that I haven’t seen anyone else post yet.

Imagine natural numbers like 1,2,3… and so on. Now imagine those are just a subset or special case of fractional numbers like 1/2,4/3,… Those fractional (rational) numbers are expressed in terms of two natural numbers.

Now in the past they couldn’t solve all equations because they were frustrated that some numbers couldn’t be expressed as fractions. They called these irrationals. But irrational numbers can be expressed as an infinite sum of rational numbers. This includes numbers like pi and e.

Next you can make all those irrational and rational (real
Numbers) to be negative. And then that’s still not the end of it because there’s more gaps! We need complex numbers :)

Then after complex you can go into tensor spaces like real^(3x3) where numbers are more like matrices. Perhaps the easiest to understand is a space of (r,g,b). Each pixel has an x,y coordinate but each point is vector valued (3 natural numbers on the range of 0-255). It should be easy to also visualize a complex number space of the same nature but with different properties.

Perhaps the best equation to understand complex numbers is Euler’s equation

e^(ix) = cos(x) + isin(x)
Or if you put in pi you end up with the most beautiful equation ever.

e^(i*pi)-1=0

That's not the issue. For those of us who aren't interested in judging him for this transgression, he's still a good comic that is quite entertaining, and we'd like to see him perform.

The issue with cancel culture isn't that people can't decide to not patronize a comic. That's always their right. You can choose to not watch a comedy special because of any reason that is important to you. Just understand others may decide differently, and they also deserve to have the choice of who to watch.

There is a difference between choosing not to watch a comedy special, and getting so outraged that you need to prevent others from watching the same special.

It's actually more hopeless than you realize. Okay, so you just arrived at your destination. Now what, unless this new world was EXACTLY like earth, you will perish relatively quickly. The atmosphere will probably have a different mix of gases. The gravity may be different. The star may not be a type G, so radiation might be a real problem. There might be nothing to eat. Certainly viruses and bacteria of that world would attack the astronauts almost immediately. You would surmise before your death that the journey was not worthwhile.

Besides the gig economy I heard that a lot of retail businesses like Walmart now pay employees by debit card instead of check. So instead of a check cashing place taking 3% of people's paychecks some bank is taking 1.x% in interchange, and if the bank happens to be owned by Walmart well who would notice.

Differences are 1) the students didn't run the institutions, with the ability to thwart rhetoric made in good faith, have professors punted etc. and, 2) protesting against Black people having to use the 'back entrance of the theatre' in the 1950's is altogether different than many of the tactics used today related to not allowing discussion about issues with which some might disagree.

I'm glad 1960's students made progress, especially with respect to difficult issues like apartheid.

I'm equally glad (and I'll bet most share the same view) that students might want a more objective look at, for example, the Israel/Palestine conflict.

The issue is the authoritarianism of the context, and the cancellation/derision of those who don't share the same view, and other ridiculous postmodernisms, such as literally removing photos of previous graduates (i.e. mostly white men) because it's offensive to the sensibilities of those who think it contravenes a positive learning experience.

Cleese is exactly right. Very few are concerned with the 'good faith' arguments of any group. It's the intolerance displayed by some camps that is the problem, not their arguments.
