On #5, I would argue that intraday leverage may be ok, depending on the assets you're trading. If you have a $50K account, buying 1000 shares of AAPL (a roughly $100K position) for an intraday trade isn't necessarily dangerous. Overnight leverage is a whole different risk profile.

I would also add another rule:

6) Think of your job as a trader is not to make money - it is to manage risk. If you have an edge, the money will come. But if you fail to manage risk, you will fail.
No, it still does - LZW assumes flat probabilities for each entry in its dictionary. After a while, both the encoder and decoder will know more accurate probabilities, but LZW has no way to take advantage of that.

The biggest issue with guile-emacs seems to be that the community doesn't seem particularly interested in it.

As a daily almost-everything-in-emacs user, I definitely understand the shortcomings of elisp, but generally speaking it does the job. Yeah guile would be an improvement, but I'm not sure it is worth rocking the boat.

It doesn't seem that the idea that elisp needs replacing has that much currency.
I don't think anybody does that type of user testing anymore. The last project I've seen a good write-up about was Office 2007, and that's a decade old at this point. Which is a shame.

Just using most web-based UIs shows that there's almost zero usability testing going on in that field, and since more and more apps are web-based, well.

I admittedly lived in New Orleans before the modern generation of "celebrity chef" restaurants really got going. K-Paul's had just opened. So most of the best restaurants were all cut from a somewhat similar high creole cloth. But Antoine's was always right near the top of my favorites--though I haven't been there for years.

The way things worked back then was they tended to stick the tourists in the front room but if you knew one or more of the waiters by name they'd give you one of their tables in the back.
We can debate the semantics but that's not "paper" anymore.

I agree that the endless Nix vs Guix discussions are getting tiring.

As a contributor to both, I'll try to explain why Guix won't make Nix obsolete any time soon:

Guix is an official GNU project, meaning they won't ever support any proprietary code. The Linux kernel is "Linux-libre", which is a Linux fork with all proprietary drivers removed, so it probably won't run well (if at all) on your laptop. Whereas on NixOS you'll have things like Steam working out of the box.

Guix also has an unfair advantage in that they started "from scratch", while Nix contains a lot of legacy cruft from "paving the way". The `guix` tool/frontend is a lot better than the various "nix-*" commands, but there is work underway for a similar unified interface to Nix.

Finally, the language: Scheme is more pleasant to work with, but I find system configuration a lot more intuitive in Nix. NixOS also uses systemd/udev which is more familiar for most people than the maturing Shepherd service manager in GuixSD.

TL;DR: Nix and Guix serve different purposes through similar means. They are both excellent distributions and clearly represents a new era of operating systems. Most people would want to go with NixOS if they want a minimal-hassle functional operating system; but if you are just looking for a decent package manager for your favourite distro then Guix may be a better choice (as long as you can live without any non-free software).

Intel is in no way losing the HPC market. There are lots of algorithms (like all incompressible CFD, so all car/boat design, even sparse matrix multiply) that gets essentially zero benefit of GPU. At most, I'd say half the popular HPC use cases see significant GPU benefit.

Karl Rupp has a very good series of CPU and GPU performance comparisons, recently updated:

https://www.karlrupp.net/2013/06/cpu-gpu-and-mic-hardware-ch...

Most of the "no GPU benefit" stems from algorithms having low FLOPS per byte. Look up Collella's Seven Dwarves for more details.

And even if we assume GPUs become dominant, Intel is going to sell at least one Xeon for every two Teslas; those GPUs need host CPUs.
Even though I compleatly agree with everything being said in the article ,it highly understimate how hard it actually is to build a semi-complex IoT product. Our startup realized this after 2.5 years in the making of a Smart Things competitor. For example, to debug something you need to check a larger set of things (cliente, backend, hardware, embedd software, network, etc). It will all get better but as of today it really is hard to achieve.
Linux GUIs follow different standards for different toolkits. Some try to use a relatively consistent core (GNOME, KDE, and xfce4 to an extent, I think), others can diverge widely. If you're old enough, or like collecting old software, you'll know several wildly inconsistent scrollbar metaphors and controls....

I find it slightly useful -- I can usually visually guestimate a tool's graphics toolkit and predict its behavior, but novice users will almost certainly get confused.

Like you I find environments I cannot keyboard control are hugely unproductive.
I wouldn't really consider ALSA as an alternative to PA, considering that PA generally sits on top of ALSA instead of replacing it. aRts and ESD of the olden days would be more comparable.
Unplugging my headphones and letting other people be able to hear what I'm listening to? I mean, with ALSA I can shut down whatever program I'm using, switch to speakers from headphones, then start the program up again but that's a bit cumbersome. Maybe it is possible with ALSA somehow but not with the programs and distros I'm familiar with. When PulseAudio came out all of a sudden Linux went from less convenient to use headphones and speakers with than Windows to distinctly more convenient.

I'm not sure about ALSA's capabilities in this area, but one thing PulseAudio does well is moving playing audio streams between sound devices. (For example, moving it from my monitor's speakers to my USB headphones.) Being able to control mixers on a per-application basis is also quite nice.

> For the purpose of defining gambling, the component of chance must be exogenous to the participants.

There are many different legal definitions of gambling (even in the US -- each state that regulates gambling has at least on definition of its own, as well as the feds, and the same jurisdiction may have different definitions in different laws) but the one you posted upthread requires only that the future contingent event on which one participant is at risk be out of control of that participant, not that it must be "exogenous to the participants".
Largely because Snowden is outside the political reach of the US for the moment, and the USG realizes it would be counterproductive to throw a public temper tantrum about it.

If he hadn't fled it's quite likely he would have faced the same kind of treatment as Thomas Drake and William Binney, if not harsher.

I think the individual retail trader is almost always outgunned informationally when it comes to intraday trades. Most short-term price action is driven by order flow and cross-asset correlations, which machines are very good at trading. They are often net trading cost earners due to rebates and capturing bid-offer spreads. That means their win rate doesn't need to be as high, so they can pull the trigger on a trade before you can, just by having lower fees and superior execution. In addition to that, they're faster, more scalable, have more access to liquidity, and are more disciplined than humans could ever be. For the ones who trade off statistical correlations, they have the best data and armies of PhDs working on signals.

There are some event-driven fast trades still done by humans, like after news or responding to economic releases, but hedge funds have highly-educated people modeling the effects of an interest rate change or earnings release as their full-time job. This area is also becoming dominated by bots doing sentiment analysis.

I think the retail trader could have an edge in a few ways. One would be an illegal edge like inside information or market manipulation. Another would be finding illiquid stocks that proprietary traders and hedge funds won't bother with and trading using similar techniques. You could also look for extreme situations that model-based traders can't understand well due to lack of data, like a merger target breaking away. Those trades would be very risky though.

FWIW I'm a professional trader and never day trade my own account or pick individual stocks. My company allows it, but I don't believe I have any edge in doing so. I just buy and hold a portfolio of ETFs.
I've used MacPorts since it was DarwinPorts. This isn't out of habit, I've tried Fink, Homebrew, Nix, and Pkgsrc. All of them can't hold a candle to MacPorts.

I have a super easy way to evaluate package managers, so I don't waste my time: can it install useable up to date versions of GNU Emacs (NS variant), TexLive, and Xorg Server, without hassle.

Fink is dead, so we can skip it. Emacs was never up to date on Fink anyway, so I quite using it early on.

Homebrew does not package texlive and has a pathetic error it prints out when you try 'brew install texlive' — this is why I refer to it as a toy package manager.

Nix, failed all of the packages and was crazy slow. Xorg installed, but crashed on launch.

Pkgsrc is the only one that comes close. I couldn't figure out how to install the NS variant on GNU Emacs, but everything else installed (including CLI emacs) and worked. The caveat is that all the packages had really strange names. MacPorts wins here because the packages are name as you would expect: emacs-app, texlive, xorg-server.

MacPorts could make it easier to package software. Hopefully they're working on this.

I would jump ship to Pkgsrc if it had better organizations and included macOS variants of packages.
I think Apple's contemporary OSes (System 7 and System 8) did a much better job, personally.

Windows 95 has the advantage that tons of people used it day-to-day, where Apple's systems were less popular. But as a person who used both, I definitely preferred Apple's design, and their dedication to designing everything about the experience.

Even the keyboard layout. Macintosh was the system that logically and sensibly separated the function of "Enter" from "Return". Two functions should have two keys, dammit. Every time I have to use shift-Enter to put a newline in a IM window instead of just hitting return, I die a little inside.

So this probably just saved me a trip down NixOS road, which was on my (ever too long) todolist for some time now.

Last year, I finally put my private systems under configuration management, but just like the author, I was concerned that both the configuration management tool and the system package manager like to exert complete authority over the system without knowing about each other, a recipe for disaster.

In the end, I wound up writing my own configuration management tool, Holo [1], which relies on system packages to install applications and deliver configuration files, and implements the additional logic to provision things that the package manager does not understand (users, groups, SSH keys, etc.).

One thing that's missing from Holo right now is a validation pass that the whole system matches the expectation described by the configuration packages. (Right now, only files that were touched by Holo can be monitored for changes, but not files installed by the package manager.)

But it turns out that that's a hard problem. A normal Linux system has a lot of moving parts that are not accounted for by the system package manager. See for example the positively huge list of exceptions in [2]. Of course, the bulk of these quickly-changing files are data, which can be skipped easily by just ignoring /run, /tmp, /var/cache, /home and so on. The question remains what to do with the rest: implement some sort of parsing for auto-generated configuration like /etc/passwd, /etc/ssl/certs and so on, or just rely on snapshots of known-good states designated by the administrator? I'm still undecided.

ALSA is not an alternative to Pulseaudio.

If your audio chipset doesn't have a hardware mixer, and about of half of laptop chipsets don't, then you can't play more than one stream at a time. If you have an array microphone, the only way it'll work at all is with Pulseaudio. If you want Bluetooth audio, only Pulseaudio bothers to support it.

Pulseaudio uses ALSA anyway (and on DFBSD it uses OSS instead); it's not a replacement, it is the only unix sound server other than Apple's(and maybe OpenBSD's) which actually works. ALSA is an audio device driver ABI; it can only expose what your chipset supports in hardware.

The problem of Pulseaudio spinning, at least when it used to happen on Linux, is due to issues in the individual audio device drivers. The reason this is a big problem is that Pulseaudio needs to run at a low `nice` value in the scheduler, or you will get buffer underruns (which sound like pops and clicks). Unfortunately this means that if Pulseaudio goes into a hot loop, it will consume all of the available CPU resources until the loop breaks. This problem can be mitigated by running pulseaudio with a control group to limit CPU time (as is done with systemd on many Linux distros). Unfortunately, DragonFlyBSD doesn't have the same thing configured, assuming their kernel supports it, so you get 100% CPU spinning.

Furthermore, DragonFlyBSD doesn't have ALSA; they have OSS.
Does this actually mean anything? It reads like a pataphor.
It's a good idea in theory, but having ridden this setup in Golden Gate Park[0], I'm constantly worried about getting doored and ride as far away from the cars as possible. I'd argue one's chances of getting doored are higher than an auto rear-ending a biker, so it would take up a lot more space to implement correctly.

Also, for passenger in a car, can you imagine (carefully) opening a door, hoping not to door a biker, only to try to cross a stream of bikes to reach the sidewalk? It's a bad scenario for all parties.

As an immigrant who come to America in my 20's, I never fully understand this. I saw people who asked a person who just experienced extreme difficult situations, "are you ok?". Apparently she was not ok. Her husband just passed away and they had two young children. Nobody would be ok unless she is completely heartless. Other sayings, like "it will be fine", "everything will be ok", etc.

I meant replacing the VM, not the Lisp dialect. The value of Emacs is the elisp code available and the platforms it runs on. I don't think there are many users who like the underlying Lisp implementation's runtime behavior.
PA is pretty painful, but credit where it's due: Now that linux's OSS support is pretty much dead and buried, it's pretty much the only way to do cross-platform sound on the unixes. Even if it is a baroque, overly complex mess (it is), it has helped to increase portability across systems.

Not that it matters, as Wayland and systemd slowly eradicate all cross-compatability in software complex enough to care.

Which is kind of ironic, when you think about it...
Or don't even justify it, just get there and pick whatever you feel like or don't. When they're like "er, why didn't you get coffee?" say "Meh, I wasn't into it, I just came because I was enjoying the conversation and quite like hanging out with you"

Being real always trumps being fake - even if that real looks like what you call "weird". Weird is the new normal... mostly because there is no normal. Everyone's weird; if they're not, you just don't know them well enough yet. I'd rather hang with 2 weird real people than 10 "normal" fake people - I don't even care if they don't like $4 coffees... because I don't even drink coffee.

That's not clear to me. By that logic, any game in which players took one turn each, sequentially, would be gambling. The fact that you can no longer control the outcome does not make it gambling. You need to have a nondeterministic component that is exogenous to the players.

I think it is super important to answer yes to that question as a patient.

At the end of the day, it it your body. You are responsible for it. You may not be an expert in what all of it does in its majestic form and function, but that is why doctors, nurses, and researchers exist.

You live in it. When you are explaining stuff, be it pain or pleasure, to a doctor, that experience is mediated by the sheer fact that your doctor is not you and does not live in your body, does not receive sensory input from your body. Your doctor receives sensory input from his/her body.

Even if your doctor has extremely similar experiences, there is no guarantee that they will fully understand you and your predicaments. Most doctors in the US know what a severe sunburn looks like, and many will have had them growing up. Most also have not seen Phytophotodermatitis (aka lime disease http://www.theatlantic.com/science/archive/2016/07/burned-by... ), nor will have had them growing up. With the growth of artsinal cocktails and people realizing fresh citrus juice tastes better, it's occurring more frequently. Now there is an educational push,but that doesn't equal expedient treatment and lots of doctors recognizing on sight yet before it gets bad.

While Phytophotodermatitis is a trivial example, for patients with serious diseases (and not serious but not common ones too) the example holds and can be expanded. Patients banding together to change this is generally what causes major changes in healthcare policy in the US president,as well as direction in research. (The most famous example is in the late 90s/early 00 with aids via act up nyc. The documentary "how to survive a plague" covers this extremely well")

So yes, you totally should question. You totally have more power than you think. Act on it.
The GMC doesn't look like it has crumple zones at all (do those have crumple zones in the frame, like the new F350s?) The front tires on it are pointing in different directions, I bet the IFS is damaged. It wouldn't be that hard to fix, though.
Except the FBI explicitly said Apple could work on and execute the backdoor internally and destroy it after use. It would never need to come out of their secure facilities.

So I don't think this was the strongest argument for Apple. A better one is that once the US can compel Apple to do this, what's to stop Russia, China from demanding the same thing?

As an answer to sibling comments: if your Emacs clone doesn't support elisp, then it's not a replacement because the elisp code out there is the #1 selling point of Emacs. And much of that elisp code exists because the editor is a flexible core with stuff exposed to elisp and all kinds of crazy stuff built on top of it.

Blackjack, a casino game with unusually good odds, has a house edge of 0.43%

You can certainly get brokers that'll accept a lower commission than that per trade, and if you're not hugely overleveraged the variance of your expected returns is going to be lower[1]. As with poker, the difficulty isn't so much the house edge as the fact there will be people or bots who are much better at it than you and/or have much bigger bankrolls to force you out of the market even if your suspicion they're holding a weak hand is justified
