I recently moved from a MBP2015 to a MateBook X Pro and what I like more is the battery life, I can work a full day without plugging it in (I work from coffee shops). One reason for the long battery life is the 15W CPUs in ultrabooks, as opposed to 45W in bigger laptops. Here are some things I did to boost my battery life (I get 7~10h)

- Undervolted the CPU (-100mV).
- Using bumblebeed/bbswitch to switch between GPUs, I never use the discrete GPU but I'm glad it's there just in case.
- Show power consumption (watts) on my status bar to keep an eye for power hungry websites
- Using Arch so it doesn't have anything I don't need running out of the box. A bit harder to install and configure though. I'm actually not sure if this helps or not
- Disabled Xorg compositor, yeah, I don't get window shadows and there's a weird flicker when I switch desktops but it gives me an extra 10~15% battery life.

There's also a utility called "powertop" that gives you stats about power consumption and a bunch of levers to improve it.

It took me a few days to set everything up but now I'm in love with the mobility.
I wish I could permanently ban results from websites that game (or pay for) their rank and whose content I am not interested in(generally the big guys like web.md, etc..) I think at some point google had an x for each result and you could remove it from the search. They didn't keep it. Does anyone know of any plug-in or script to do that? I know i could do -web.md but there are way to many sites that occupy the first pages of results I want removed

Without natural predators like wolves, bears, or bobcats, the deer population in certain areas of the United States has exploded(1). This negatively impacts overall biodiversity(2). I doubt deer like being eaten, but that's the process of life, and its vital to maintain the existing biodiversity we enjoy today.

So why would you feel guilt for the cycle of nature? Without deer, buffalo, or other herbivores in suburbia or urban environments, there has to be something to check plant growth.

Could that be because of using Jupyter notebook itself? I like Jupyter for data and machine learning 'journalism', but I don't see it as the a proper medium to address the 'last-mile'. The insights driven from Jupyter, in my opinion, are not actionable and well integrated enough. It is becoming a de-facto medium reminding me of shared Excel files.
>If you're doing a legal ICO it has almost no benefit over traditional fundraising,

The way I read that is there are benefits. Seems to me it’s significantly more cost effective than a private offering and order of magnitude more cost effective than a traditional IPO.

Not knowing who owns the shares is in fact illegal.

Meh, we're just talking past each other, probably were from the start. I'm saying, "time-and-a-half beats working on games at EA for 80 hours/week for base, your factory-working friend has it better than a lot of tech workers" and you're saying "overtime sucks". Both statements are true, we're just negotiating the price...er, wait, wrong metaphor.
I wouldn't buy it. It's been modified in a way that makes it very difficult for someone to find a person willing and capable of doing maintenance on it. If something in a system he retrofitted breaks, he will just about be the only person capable of fixing it.

This was an extremely interesting paper to me, about a topic that I see as economically and sociologically fundamental.

I was actually impressed by the methods they used. I found myself thinking "this is what I'd really like to see," and then they'd report it. Validating their method on the MusicLab data seemed critical to me, as did examining reddit resubmissions versus YouTube views.

Although I thought methodologically it was almost as well done as it could have been outside of an experiment, I disagreed with the author's conclusions. They acknowledge some of the problems, such as the problem of the huge number of forgotten posts they didn't model at all, but other issues they don't.

For example, it seems the question of most interest is, given an observed post score, what's the actual "quality"? If you look at, say, Figure 3, it's apparent that there's huge variability in quality conditional on score, as observed score increases.

I think the correlational-style relationship they focus on obscures things like this that are critical to interpreting the findings. Yes, there's a strong estimated relationship between quality and score, if you ignore all the missing data that constitutes the bulk of submissions, and the fact that the relationship is being driven very strongly by a large quantity of very low-"quality" posts versus everything else, and the variability everywhere else. It's an odd, heteroscedastic, nonlinear relationship that isn't well-captured by a correlation, even a nonparametric one.

I also would have liked to see examination of variability in links across sites. How much variability is there in rank of an initial link, to the same material, across reddit, HN, Twitter, etc.? Maybe tellingly, the authors report the relationship between YouTube views and number of reddit submissions, but not the relationship (if I'm reading correctly) between YouTube views and rank of initial reddit submissions, which is kind of the key relationship.

So, liked the paper but if anything it just reconfirms the conclusions of earlier studies to me, that social network dynamics has a big influence on apparent popularity.

Absolutely. This license change takes it completely out of the contention for anything I would have previously considered it for. Can you imagine if Nginx said you had to release any software you run behind it as FOSS?

>it is but it's not feasible for the system theme to change the styles of websites.
Just ask any Linux user that uses dark themes and you will find out what happens when the system theme messes with the site theme.

It is done completely different fashion than it was done on gnu/linux, on linux it was probably done by changing user agent style sheet (changes default bg color on body etc), when here it is done with media query (which webdev must explicit implement on his part so he can make sure that everything works).
Also on Linux GNOME has had a popular dark mode for its default theme (Adwaita) for ages now, and KDE has a bundled dark theme bundled by default (IIRC, haven’t used KDE in ages).

I think Android has this option too?

Basically, it’s not just a “macOS thing”, lots of systems now have dark modes.
I'm sure that the Elder Scrolls 3 had situational music, and that was a few years prior. TES 4 did for sure, and that was a year before. I'm a big fan of Jeremy Soule (composer of SupCom, Elder Scrolls 3,4,5).

Coincidentally, recently project Crostini has reached Chrome OS stable. To those who don't know what it is - Crostini enables running Linux apps on Chrome OS (https://chromium.googlesource.com/chromiumos/docs/+/master/c...). This makes Chrome OS a lot more appealing than it used to be, especially in combination with top end hardware like Pixelbook or Pixel Slate.
My guess is based on Python 2, where range(n) would return a fully inflated list of 0..(n-1). If len(x) is large, you could be allocating giant temporary lists just to iterate through them once. Using xrange() was the Python 2 solution (it would return a generator instead), but, if I recall correctly, Python 3 fixed this s.t. range() returns a generator.

I've been working on and off with formal agile since 2002, and worked on "disciplined professionals" teams.

You know what is disciplined? Formalizing a process and following it, even when it's inconvenient or annoying. Getting by on talent, high bandwidth communication, and sufficiently small scope might work, but don't call it "discipline". It's luck and narrowly defined circumstance.

Try using that method on a $50M enterprise project with 100+ developers and see how far you get before you choke to death.

The parallel stories of Tesla and Apple, as Model 3 has its 'iPhone Moment'
The first link of the top header is 'INTRO' leading to a page which literally has 'What is Qubes OS?' as the first h2.

The third link of the top header is 'TEAM' leading to a page where Joanna Rutkowska is the most obvious topmost item, appearing above the fold on many devices (even my phone!), complete with her title(s).

Sometimes comments make my day. This is not one of them. I am achingly speechless.
I can't really answer the implicit or explicit question of "what have you got against Tesla?", or the accusation of being emotional, without bringing in an alternative.

Which makes it difficult to have the discussion about Tesla-as-Tesla. Admitting that I have an emotional reaction to an individual is the honest response.

My policy, in your position, would be to just ban Tesla posts. When a conversation topic becomes repetitively boring, I ban it, as there are plenty of places to discuss Tesla or Elon Musk or any other topic.

We are to the point where the camera(s) are not just capturing a 2D bitmap. They are using camera(s) and other sensors to create 3D depth maps to offer on-device scene manipulation. We are in the beginning stages of capturing 3D images which offer the user the ability to change focus, lighting, and entire scenes. Check out photometric modeling and the Lytro camera systems.

I don't understand the line of reasoning. Can anyone give me a lay explanation?

My understanding of the license change is basically "if you use MongoDB to support any site, all software higher in the stack needs to be released as well".

Is that accurate?

If so, why can't an author make this part of the license?
>Inverse logic is valid too.

Actually it's not.

>Any sufficiently popular "thing to crack" is doomed in the long run. ... They are just training offences.

No, because these are not symmetric operations. There is nothing mathematically impossible about bug free software. While the Halting Problem means that we can't just formally take any arbitrary program and solve all its states, it is possible to formally prove small programs and additively build up, and to approach a limit of zero with enough brute force over time particularly in simple programs. If they are not changing and actively gaining new informal features then they will not be automatically gaining new vulnerabilities either, and for all these very reasons it's standard practice to try to separate security core code and make it as simple and static as possible beyond bug fixes.

So unlike the real world in software defense is actually in a naturally stronger position if managed well. Software history is a spiral not a circle, security practices are improving and legacy is being reduced over time. A lot of easy mistakes of the past don't happen so much or at all anymore, and Apple has definitely benefitted long term from the hunt for exploits in hardening their ecosystem. Bugs still exist, but they're not low hanging fruit anymore, they're harder to find and more restricted in scope and more must be chained together for wider access.
Sounds cool in theory, but my small experience with a past company's serverless API is that it made impossible to debug. It was like deploying to a black box. There's no way to hit the API locally, etc.

The decomposition of urea [(NH2)2CO] produces two equivalents of ammonia for each equivalent of urea. It's not clear from the article how much (if any) of the ammonia gets consumed by the bacteria.

> Is large amounts of ammonia easier to dispose of than urea?

Ammonia's boiling point is -33 C, so pure urea is a gas a room temperature.

When dissolved in water, ammonia is in equilibrium with ammonium hydroxide. So the stuff can stick around until consumed by microorganism or it evaporates.

Both urea and ammonia can be used as fertilizers.

"Solaris" by S.Lem
They didn't reveal my secret disguise so I do wonder.

My 'secret disguise' is truly ingenious. I am a cyclist and I can transform into a regular pedestrian without anyone being suspicious.

In 'cyclist mode' the trick is to wear an extremely hi-viz jacket and to cycle at an unexceptional speed, taking short cuts through parks and along canal tow-paths. Those pesky Americans in their cars with access to every CCTV will never catch me that way.

I can stop at any time and just get off the road, maybe to 'have a drink' or maybe to change my outfit as I could be 'too hot or cold'.

The helmet, sunglasses and face mask makes it hard for facial recognition to work, yet I am not 'in disguise' as per the flaky accessories shown in this video.

Of course I have a fleet of bicycles, including a folding bike that can be taken on public transport as well as wheeled into buildings. This and other bikes in the fleet can be abandoned as needed.

It goes without saying that if I do encounter trouble then that D-lock and accompanying chain is there if I need it. I would prefer not to be nicked for grievous bodily harm so I am more likely to step up the pace and take flight rather than fight. Again, due to the special nature of being a 'cyclist' I can jump every light with impunity whereas those men in black can't quite do that.

I can also have a full change of clothes in my bag, again this is legit due to the bicycle. I don't even need to leave fingerprints. Plus a tracking device is quite hard to place on a bicycle without the added weight being noticed.

What is also pretty good is that the bicycle gets me to places in time. There are no traffic delays or train problems.

The tools that go with the bike are pretty good too. I can carry all that is needed to break and enter into a building if that was needed (which it isn't). Anyone else carrying a knife or an adjustable wrench has some explaining to do if they get stopped and searched.

The bag on my back also does a good job of stopping small arms from damaging my vital organs, not that getting shot is a problem outside the U.S. and occupied territories.

It all comes with plausible deniability. I can navigate by landmarks too. Even better this 'stealth cycling' mode of getting around is not worthy of Hollywood. Some guy bumbling along cycle paths is way too boring for the movies so my secret disguise is always going to work.
I'm a bit irked that a technology of this significance has no videos or demos or actual use cases, just a PR blurb. Is it confidentiality, or is it too early stage? Otherwise X Prize becomes another congratulatory event. This feeling seems to run through the entire site as I click around.

RTFA, especially before snarky dismissals: "meeting the competition parameters of extracting a minimum of 2,000 liters of water per day from the atmosphere using 100 percent renewable energy, at a cost of no more than two cents per liter"
okay you're right, the analogy doesn't fit as well as i thought when i woke up this morning.

at a very high level i do still think there are some similarities. people want to consume a tailored tech experience that costs time and money to put together. they don't want to put in any effort to improve their experience, and they definitely don't want to pay for it. what do we do with/for these people? i say we leave them be and document workarounds for people who are willing to do a little reading.
I came to write this too :P
>I'm turkish and because of hidden arabic imperialism and assimilation rooted deep in islam, I refuse to use even arabic words which are common in turkish.

Ahem, but I think most Arabs complain about Turkish imperialism. I don't think Turkey was ever conquered by the Arabs, but the reverse is true.
It's a valid concern, but I don't think the line is as muddy as it seems at first glance: would I expect a Pyongyang hotel room to be bugged? No. But I also would not assume that it's not. With this construction you get two kinds of being surprised, with one taking all the variability derived from suspicions and the like while the other should remain quite stable. Just like most people were simultaneously surprised and not surprised at all by the Snowden revelations.

Obviously one would have to explicitly exclude from the "reasonable" test the kind of surprise that was not triggered by Snowden, because otherwise all our greatest fears would become legal by definition.
I read the article. Do you know how many of these things promise gallons and deliver drops? Pardon me for being pessimistic about it.
