I liked Vyvanse more than Evekeo. I had much less depression, was much more motivated and able to focus during the day as well as evening, and I still could get to bed easily and sleep well-enough. But, I acted too hyper on it.

Perhaps I could try to practice more self-control and continue taking it or could try taking 1/2 the dose, but after I had problems, my doc put me on Evekeo. I take one in the morning and mid-day, and I'm much more even-keeled than on Vyvanse. The downside is that it's not time-released. I have ups and downs and my brain is not working as well in the evening like Vyvanse. I also don't get sleepy as much at night when I should. But, it's much, much better and safer for me than not taking anything. I might start taking a low dose of Zenzedi in the afternoon to see if that helps problems getting to sleep.

Evekeo is 50/50 dextroamphetamine/levoamphetamine; in some sources it's just called amphetamine sulfate, but the ratio is important.

Zenzedi is also made by Arbor Pharmaceuticals and is pure dextroamphetamine sulfate (which is the really addictive one).

Adderall/Adderall XR is 75 percent dextroamphetamine (the regular Adderall is a mixture of dextro salts in that 75 percent) and 25 percent levoamphetamine.

In comparison, Vyvanse is the prodrug lisdexamfetamine that is converted to dextroamphetamine and lysine by the hydrolytic activity of red blood cells, so it's time-released.

I'm told the levo form is for increased wakefulness and improved focus and dextro is for energy and speeding up executive function. I don't know if it's really that simple, but that seems to mirror my experience.
I had to go through several rounds of edits to get the wrapping right - HN doesn't automatically wrap code blocks.

Still, I prefer using code blocks to do bulleted lists on HN. Not sure why. Maybe its that thing I just confessed to having for laborious hand editing.

Probably does mean I'm being a jerk to mobile users, though. Eh, I can go change it.
Actual old hardware has a problem though: might me impossible to find.

For example I live in Brazil, I learned to code trying to port MSX Basic games to a 286 GWBASIC, because I never saw a msx in person.

Also, some other hardware I would love to fool around and never saw one:

C64, Amiga, Sega Saturn, 3DO, PC Engine, non-Intel Mac, a real NES (I owned a clone once), programmable calculators.
It was simply modelled using a bunch of binary variables. Basically for every segment, we want to find the position of every line. So first we tried the 'traditional' approach of modelling the positions as a set of binary variables that say

Line_i_at_position_k

It just takes a long time because there are a lot of binary variables, and the penalties derive from the binary variables in an awkward way.

Later we started using a model using variables like

smaller_i_j

Just denoting whether line i is at a smaller position (index) than line j. You can enforce total ordering using the triangle inequality as a constraint. And the penalties very directly derive from the binary variables, because the penalties are all about things like 'apply penalty if line i is left of line j'.

Another thing to note is that New York-Washington is all connected. But some of the connections have only a single (commuter rail) line. So mathematically speaking, Washington and New York are actually independent. The MILP solver sometimes seemed to have trouble finding those independent components, so it helped providing them as separate models.
defacto, no debate...
> There are disciplines that have been teaching concentration for hundreds of years that produce people who can concentrate at will under pretty much any circumstance. To teach beginners they choose a very quiet, distraction-free environment.

Can you point at specific resources (name of the discipline, quintessential book about subject) for learning how to practice deep concentration, even in the face of very suboptimal environments?
most certainly.

Posting a video like that without context (if you even have any available) is inflammatory and unhelpful. Is there really an expectation that an english speaking viewer can parse the relevance of a video clip like that? As if we don't have our own media personalities saying wild things about foreign nations? Or presidential candidates (with significant national support) talking about using nukes?
I think this proves that If we practice anything we will make the improvement.
I read an amazing theory of this on reddit: https://www.reddit.com/r/Nootropics/comments/4z8znn/can_one_...

>As far as I know, when ADHD individuals are treated with amphetamine(s) even long-term, the dopamine D4 receptor in the prefrontal cortex does not down-regulate. This means that the pro-cognitive benefits of the amphetamines, namely executive function improvement [ability to organize thoughts, plan your day and exhibit sustained attention] are all improved.

>However, what most people experience when they first start Adderall or any amphetamine is the massive surge of motivation and in particular energy. This energy can be massively addictive as it is basically anxiolytic first time around while simulteanously giving you big bouts of motivation and pro-sociability. Neuropsychopharmacologically speaking, these effects are due to dopamine D2 and D3 receptor stimulation in the nucleus accumbens (and effects in the ventral tegmental area, accounting for some of the motivating experience, most likely), however, what is important to note, is that after somewhere around 1-3 weeks, these receptors down-regulate and dose-escalation is needed to retain the pro-social, pro-energetic, pro-anxiolytic effects.

>In other words, while amphetamines may be a piss poor choice of drug for sustained energy production long-term, the pro-cognitive benefits for individuals with executive function deficit (whether diagnosed ADHD, drug abuse, or traumatic brain injury) do exist in long-term. I think this is one of the reasons that some ADHD individuals are capable of staying at the same dose for a long period of time and still reap the benefits.

In other words, the 'high' that drug users get from doing speed once, is very different than the effect that benefits people with ADHD. While the high tolerates over time and requires higher and higher doses, the beneficial effects don't seem to tolerate and last long term.

Amazing process to build such an impressive result. Man I wish I could work on problems like this. This would making come to work fun again.
One of the things I miss about working in blue-collar jobs is the sanctity of the coffee break and the lunch hour. 9 o'clock, noon, 3 o'clock, tools down, everybody goes to the break room and has a cup of coffee, shoots the shit, catches up on what else is going on.

The plant I used to work in also did daily standups. They worked a hell of a lot better than any I have ever seen in software, since they started the minute after everybody was supposed to punch in, rather than some amorphous time mid-morning when somebody decided there might be a better-than-average chance of everybody finally dragging into the office or there not being some other regularly scheduled meeting.
Sounds like a great way to improve your relationship with the client /s
This sounds like the perfect opportunity for some researchers to create nanobots or something to act like spinnerettes. Wonder if there has been any such thing?
Ask HN: What are the possible approaches to develop a chatbot?
Let's say we want to develop a chatbot whose objective is to be able to talk to people about cars (i.e., "What do you think about BMWs?", "What is the fastest sedan in the market?", etc.). I am narrowing the domain on purpose.

In order to build such a bot, some approaches come to mind:

1. Hardcoded answers: use NLP to understand the meaning of the user input, go through defined rules (if-else basically) to choose the appropriate answer from a set of hardcoded, pre-defined ones.

2. Machine learning on existing conversations about cars: if you have access to lots of conversations about cars, you could use machine learning to train the bot to understand the meaning of the user input and to formulate an answer based on the data.

3. Machine learning on generic information about cars: same idea as above, but using generic infomation about cars (i.e., wikipedia, magazines) to formulate answers. NLP would need to be used both to understand the user input and to formular syntatically and semantically correct answers.

Questions: Are these approaches indeed viable? Are there others? Are there examples of bots using 2 or 3 out there?
Great Trigonometrical Survey
I was in a similar situation as you (south Indian with only one name), and after trying to reason with their customer support, I found it easier to just use a fake name.
If you think my real name is fake for no good reason, go ahead and have a fake name that "sounds real".
This is EXACTLY how we have it at our office (Series D startup). On a daily basis, I pend about half my time in the open area with my team and everyone else dropping by, and the rest in a room where I can be plugged in at peace to get some concentrated coding done. The office rooms range from 1-2 person rooms to 6-10 person rooms, and all of them can be used at any time of day by anyone in office.

It's funny how I never have to stretch timelines or have communication issues with this setup.

+1, would recommend.
I'm glad it's working out for you!

Our company (also a non-tech company!) is investing in such a space for us and I'm very very excited. Excited and grateful.
> There lies the problem. If its some unrelated people discussing stuff that doesn't interest us then its just background noise and get filtered out. But in office space it is exactly the opposite. You sit around with people who are doing similar work and most often what they discuss is directly or indirectly related to you/your-work. This is a problem.

I can't not pay attention to background noise. It doesn't matter how irrelevant it is, or even if it is speech or not. I also always have to be on guard all the time in case some actually does try to speak specifically with me. Thus, I live in constant fear of interruption.

Is a termite mound any less "nature" than some random patch of earth and rock? What about bird nests, beehives and beaver dams?

We are nature. The Universe is one continuous stream of change.
Several times over the years I've had an office with a door. Normally I kept the door open, but I would close it if I had work that required extreme (for me) concentration, or if the environment outside was excessively distracting that day, etc. IME, this is quite common for other people as well.

Since I have trouble concentrating when people are talking and get quite unhappy about it but managed to keep my door open the vast majority of the time, I have to wonder. Was Bell Labs an excessively noisy place, or were the closed door people there those kind of people?
Solve lots of problems.

Given you are asking on HN, I would guess that you code and are looking to become better at programming problems as well.

Ask HN: Learning to code, without a computer?
I have a friend who is incarcerated, and is dedicated to learning how to code, no matter how slow or arduous the process may be. He has no access to a computer, just books and writing utensils. While it may be very difficult, what are suggestions you have on how to give him the best chance for success?

Even if he's not learning a specific language, what are some background concepts he can learn in depth that will help him understand coding? I recommended he study algorithms as a starting point but I am not a dev and am not sure how to proceed without a computer.

I realize this is an unusual question, but I greatly appreciate any responses. It's sad that someone so badly wants to improve themselves and can't easily do so because of our archaic prison system. I want to help give him a chance to have a real profession once released. Thank you!

So if it is unfortunate, what classification of people, in your opinion, should be running it?

What a weird comment you have posted... You love the CIA? are you a sadist?

I am serious about that question, as while I agree that all states need their intelligence services - the CIA has done some downright EVIL shit. And if you "love the CIA" and are unfamiliar with their history, then you're a fucking moron.

Now, its not to say that the US needs to, in their own best interest, remain as a world super-power... and we shall -- but its to focus on the fact that we can do so in a better fashion.

I take the words "I love the CIA" to mean that you're either a sadist, a child of an op, or young and stupid, and by stupid - I just mean not critically thinking about what you have said/what your understanding of the CIA has done/is.

Again, The US will be the predominant power in the world for the foreseeable future, but have some humanity -- something the actions of the CIA fucking lack.

And if you love the CIA so much, you'll realize that they own this country, and that is not necessarily a good thing, you sound naive.

If it's not a big deal in nature, then it happens infrequently, yes? So the sows are kept in tiny pens (or pinned on their sides as in the photos in the article) to make reproduction a bit more efficient on the farm than in nature?

This was given as an example of something that looks more inhumane in pictures than it really is. The reason it looks inhumane is because one imagines the sow would prefer freedom of movement, as other living things do. The reason why it is done is certainly relevant, as is how long they are kept in that position, whether they ever appear to be in distress trying to move about, etc.

None of this is visible in a photo, and needs to be explained. However, I don't buy the argument that people have no right to see where their food comes from because they just wouldn't understand what they're seeing. A system where living things are raised for our benefit seems like a place where more transparency is called for, not less.

If anyone cares to share, I'd love to hear some opinions about at what point someone switches from "non-mathematician" status to "mathematician" status.
Nope, public shaming is 100% legal and protected speech. In specific cases it may be a contract breach, but that does not make it illegal. The largest direct problem with this stuff can be a tiny hit to your reputation.

That said, they may sue or counter sue you, which is often a dumb move but by not paying you that have demonstrated sketchy behavior.
> (Not that I agree with this bastardization of "meme" to mean "silly image with text overlaid in capital letters", but unfortunately that is what everyone is calling these things.)

The term for that is "image macro" [1]. An image macro represents a meme when the image is associated with a particular joke format, catch phrase, archetype, etc..

Of all the answers offered here, the only ones that get to the heart of the matter are those that make the distinction between inertial (non-accelerating) frames of reference, and those that rotate (and therefore have at least centripetal acceleration). In Newtonian and post-Newtonian mechanics, only inertial frames are equivalent. A geocentric frame (with a rotating Earth) spins the whole universe once a year; fix the Earth's spin, and you set the universe spinning once a day.

It is perfectly legal for you to mangle your own web site. Even if it's a site you made at someone else's request.

Unfortunately, probability and stats are not easy to teach, and even many professional scientists / researchers have major confusions about the subjects. Common sense actually provides a decent enough guide for most people (i.e a baseball player with a high batting average is more likely to hit the ball).

Euclidean geometry as taught in school does seem rather archaic and out of place though. Some people say it's an introduction to "proofs/rigorous thinking", but it seems to me that that purpose could be better served with a first order logic class.
However, be aware that

1) factoring costs money - you won't get 100%; make sure you take care of that in your asking price,

2) make sure your contract does not prevent the transfer your receivables to third parties without the consent of the debtor. Yes, there are contracts like this, usually as a part of take it or leave it, there are others waiting at the door contracts.
A more effective strategy to constant surveillance is to simply raise the background level to just below actionable threshold, so that way their intelligence is effectively useless. That is, really, you should just sit around all day and talk about how you dislike what they're doing, think they're career criminals betraying the nation, that you want to actively do something about it, etc. Bonus points for mixing that conversation with discussion about how you'd like to tour DC and see the various monuments, including the Washington monument, Lincoln memorial, and WWII memorial.

If the background unhappy chatter is close to actionable (or is in the mind of the classifying algorithms), then actionable chatter (eg, actually planning an attack) can only be distinguished from background chatter near when the plans become "active" in some sense, and likely too late to meaningfully respond to. (To use a physics analogy: if you try to predict cavitation in flowing water really close to boiling, it's harder.)

In many senses, simply embracing openly that we're very angry as a society, even in the face of constant scrutiny, prevents that same constant scrutiny from determining when we're planning something. It can only really tell that we're pissed off, in general.
