> I believe that one of the most "abused" drugs for "productivity" is currently Modafinil, far more powerful than Adderall and without all those side effects.

Modafinil is easier to acquire than Adderall, but it certainly isn't "far more powerful" than Adderall. Just the opposite, in fact, which is also why Adderall is a more tightly controlled substance than Modafinil.

Modafinil is a poorly-understood medication, but we do know that it has a moderate affinity for the dopamine reuptake transporter, which is a mode of action that overlaps slightly with other stimulants such as Methylphenidate. The remaining, additional modes of Modafinil's action are still a matter of active research.

Adderall, meanwhile, not only inhibits dopamine reuptake like Methylphenidate and Modafinil, but also enters the presynaptic terminals to exert effects within the cell. Through a series of actions, it forces more dopamine into synapses than would normally be released. This essentially makes it more powerful, and thus more prone to abuse, than Modafinil.

Those same intra-neuron actions also make Adderall potentially more neurotoxic than Modafinil. By upsetting the natural dopamine balance within a cell, Adderall can theoretically overwhelm certain systems that keep the cells working properly. Dopamine metabolism can unfortunately produce toxic metabolites, which are difficult for cells to cope with when produced in excess. Adderall can indirectly produce enough of these toxic metabolites to cause cell death. There is much debate over the exact dosage level at which this damage happens, but there is already one controversial study showing damage in non-human primates at typical therapeutic doses.

Modafinil is not the safest medication either, given the number of potential sensitivity reactions that some people have. Taking Modafinil without a doctors supervision, as many here seem to do, is thus not a good idea. Fortunately Modafinil seems to be more self-limiting due to the unpleasant side effects many experience at higher doses, such as decreased verbal fluency.

Long-term, the largest problem with Modafinil might just be its long half-life. Although the marketing material would lead you to believe it doesn't affect sleep, it's virtually impossible for a wake-promoting agent with an incredible 15-hour half-life would not negatively impact sleep. The 15-hour half-life means that by the time you're ready for bed, your body has only eliminated roughly half of your Modafinil does from the morning. Long-term sleep impairment is not conducive to long-term health.

Beyond all of this, there is a conversation about how the "productivity" aspect of these stimulants is largely limited to acute dosing, and is heavily prone to tolerance and withdrawal effects, but I've gone on long enough already.

Nike and Levi's are bad examples. They use brands as illusions of superiority. Money in this case is not spent on R&D but spent on marketing.

Also how can you be the domain expert if you open source everything you know? The millions you spend on R&D are given away and allow others to arrive at the same knowledge for $0. How does that work out for a company from a competitive standpoint? You are basically shooting yourself in the foot in terms of staying ahead and being a domain expert.
Semi off topic, but are there examples of coroutine usage in any relatively popular open source C or C++ code bases? The only thing that comes to mind is the MAME and MESS code bases (I could be wrong here). We see coroutine articles on HN from time to time but I've always wondered who or what software out there are using these types of techniques.

Yep. I just applied for a few, and here's what I got:

- 70,000 Marriott points which I estimate to be worth about $700, based on the equivalent cash price I'd have paid for the hotel rooms (which I do have plans for)

- $890 in cash bonuses

- 50,000 ThankYou points which are worth $500 cash (the trick is to request mortgage or student loan redemptions, which can be made out to the bank in which you have a checking account, and then just deposit it in your account. The redemption value is higher this way than with the normal cash option.) or more for travel (probably will just take the cash as I have enough airline + hotel points right now).

The tilt towards cash or cash-redeemable bonuses is intentional, as I have enough points of various types to support my travel plans.

One other 'danger' I've seen some fall into is valuing their points based on the cash value of whatever they redeemed them for. For example, it's common to see people redeem airline miles for a ridiculous $10,000 ticket, and then claim they got 10c/mile or whatever based on that price. In my opinion, unless you would have paid $10k cash for that ticket had the points not existed, you haven't gotten 10c/point; you've gotten $(price you would have paid for a ticket) / $(pointsRequired).

I have to spend a little over $10k to get these bonuses, which will be almost entirely in manufactured spend. I'm most certainly not spending a single penny more than I would have spent if credit cards didn't exist at all.

It's also worth adding a few statistics:

- Total credit card debt I've ever held in my life beyond the grace period: $0

- Total interest I've ever paid in my life: $0
Primary workstation is a custom tower with Arch Linux. Secondary is a dirt cheap laptop with Fedora, home server is FreeBSD. I also have a monster headless workstation at my job that runs CentOS. Oh, I forgot... I have one of the newish Dell Venue 8000 Android tablets too. I got one of those folding Microsoft bluetooth keyboards to go with it and it makes a pretty capable little SSH terminal that I can actually be productive on as well.

I mostly use Python, C++, Fortran and Haskell. For C++/Fortran, I mostly use the Intel compilers or Clang. I do my coding in Vim, with a few plugins to add the IDE features that I actually use. I use a mix of Kdb and Idb for debug work, both are really awesome.

I use i3 pretty much exclusively and urxvt+tmux, with some bits and pieces from KDE (e.g. Dolphin).

C/C++ don't have much of a runtime too (libc's "runtime" component is often not used, and libstdc++'s is rather controversial). Standard Haskell functions (with types like `a -> b`) are pure, unlike (most) other mainstream-ish languages. Of course you can do IO, which of course is impure, but it is cleanly separated from non-IO.
Unfortunately, most casual and first-time users associate Adderall with the honeymoon phase you spoke of, not the actual long-term therapeutic effects that come from proper therapeutic use and dosing schedules.

Generally speaking, conversations around using Adderall for productivity center more around the hyperactivity and unnatural engagement brought on by too-high dosing or acute use. Adderall is meant for long-term therapeutic use at reasonable doses, where the hyperactivity and super-focus aspects give way to tolerance and leave the user with just enough of a correction to offset their ADHD.

Abusers and non-ADHD users, on the other hand, tend to chase the initial euphoria and the hyperactivity that comes with sporadic, acute dosing and higher-than-normal dosages. Tolerance inevitably catches up to this manner of usage, and the downregulation of prolonged elevated dopamine and norepinephrine levels combined with compounded sleep debt inevitably catches up with them.

The only "trace" that you could find would be a wire transfer from an exchange to a bank account, and even that isn't too suspicious, because I would imagine that large exchanges do that regularly.

You could also sell the bitcoins for cash in person over time, and avoid any traces.

I like how the reason for "chargebacks" is often touted as "consumer protection" when the real reason it to line the pockets of the credit card duopoly and ensure the merchant always gets screwed.

In many developed countries there are consumer protection laws which entitle the buyer to Replacement, Repair, Refund (in that order usually), so a merchant not adhering to these laws could endup in serious legal trouble as is.

Bitcoin at least gives a choice to both buyers and sellers just like plain old cash does

Bitcoin, Cash and Traditional Banking (SEPA etc) provide an alternative for commerce where one is free from Visa/Mastecard stupidities and ensure that the Visa/Mastercard duopoly is actually forced to compete and not grow into a more dominant and more abusive entities than they already are. They provide an alternative to being tracked and data-mined and having personal information sold to god knows who :( People do not value their privacy until they lose it, and by then its too late.

* Cash allows me to pay (quite anonymously and without fear of being an entry in some datamine) for things locally

* SEPA bank transfer allows me to pay EUwide for goods and services reasonably quickly and for no fees (thank you EU! credit card duopoly must hate SEPA)

* Bitcoin allows me to instantly pay world wide with ultralow fees, its basically electronic Cash (credit card duopoly do hate bitcoin with a passion, just yesterday they prevented neteller from bridging bitcoin and credit card worlds which IMHO is anticompetitive! http://blog.neteller.com/2015/04/new-deposit-option-bitcoin/)

I forgot the last time I had to use a credit card (or paypal and their "consumer protection") in the last year, and my life both personal and business is easier and better for it.

I used Adrafinil before Modafinil and the effects were similar - I was taking 350mg of adrafinil for similar effects to a 200mg Modafinil. I did go as high as ~650mg of Adrafinil, and it definitely gave a stronger effect than just preventing / clearing tiredness.
I've been running Ubuntu as my primary desktop since the end of 2005, tried a multitude of other distros but always come back to Ubuntu - it just "works", the font rendering is excellent out of the box, package management is superb, yadadyadayada.

Relevant interview with the Economist's guy in charge of digital (overall a fascinating examination of how they're evolving): http://www.niemanlab.org/2015/04/the-economists-tom-standage...

The Economist has taken the view that advertising is nice, and we’ll certainly
take money where we can get it, but we’re pretty much expecting it to go away.

So a majority of our revenue comes from subscriptions, and always has. The
proportion of revenue that’s coming from subscriptions is going up, and
will probably continue to go up. So I’m very very happy that that’s our
business model, because I think that’s sustainable. People do seem willing
to pay for our journalism, and our digital subscriber numbers are going up
very nicely.
> people want to work, and to feel valuable.

That doesn't translate into "people want to work 50 hours week under constant petty pressure from management". Maybe some people feel valuable if they cook a great meal and share it with friends. Maybe a 2h workday is all what is needed to feel valuable.
This story grows more significant with each passing year.

No. Costco's default position is to accept no credit card. If you have a membership there you pay with Cash or Debit (Check card).

AMEX has a higher than normal merchant charge, so many businesses (especially ones that work on many small transactions like restaurants and convenience stores) don't accept it.

Costco and AMEX had some kind of deal for a very long time that allowed you to use AMEX cards instead of cash/debit, and if you got a Costco branded AMEX card it acted as both your membership card (it has your Costco ID and photo ID on it) as well as gave you some percentage of total purchases back at the end of the year. [1]

We've been Costco members for about a decade and the Costco membership fee is easily made back on the low prices we pay for toilet paper over a year. The rest of the prices are good enough that it almost doesn't make sense to shop other places for a great many goods. And if you don't have an in-depth knowledge of pricing and quality, you can usually be assured that most of the stuff Costco sells is of reasonably high quality at a good price.

My wife and I pretty much only buy our wine there. They have a deep selection, and their $10-13 wines are easily $17-30 at the local wine stores, and $30-70 at restaurants and are of pretty consistently high quality.

We don't do as much grocery shopping there, with just two of us, all the bulk items are simply too large and we end up throwing away most of the food due to spoilage. For large families though I think it works very well. We'll buy meat and repackage it into our freezer, and milk, yogurt, some frozen items. We also get detergent, medicine, bulk cleaning items, coffee, nonperishables, that sort of thing.

I honestly don't know why people who live within reach of a Costco don't have memberships. There's always some kind of excuse about bulk items, but seriously, between wine and toilet paper the membership pays for itself for us at least 10 times over during a year. And we get several hundred dollars back every year from their AMEX program.

Sir, Thanks for your response.

May i please ask you, why you think its exact copy of another site, for us exact copy would be if someone tries to copy the code or at least design etc.

Pitchmantra is designed and developed ground up, using PHP Yii and Bootstrap 3, using various APIs etc.

here is list of advantages
a) publishers list are tracked on weekly basis and updated once in a month actively
- we have browsed through 1000+ sites and curated list of only publishers link which are active (for example Gigaom.com is now shutdown and allthingsd is merged with wsj)
b) In addition to delivering pitch to 100+ publisher we also submit manually startup details to startup listing/directories sites like killerstartups.com, etc and this is again based on product and region of the startup
c) By submitting your startup on listing sites, you got good quality backlinks, SEO benefits, social media mentions etc.
d) After factoring discount of $30, we are charging only $39 for BOTH the service (vs. other provider charging between $49 and $75 for one service)

now, regarding your question about spammy part, we don't think so it will be considered as spam, since all these publisher and listing sites wants startup to pitch to them.

Happy to answer if any more question.
This GAO report is interesting. Some dopes in the popular press picked up on it saying "passenger wifi is linked to airplane control", because vague mention of that was made in the abstract. But, of course, the report isn't about that at all.

But it's more interesting in its recommendation that the FAA develop a holistic "agency-wide threat model" for its NextGen IP-based air traffic control system.

Haven't we outgrown the idea that the developers of large-scale systems should also be responsible for testing it? Haven't we understood, for a long time now, that developers have blind spots about their own work?

The danger of blind spots is only amplified by large bureaucratic organizations spending tons of money. If the FAA has "a" threat model, won't potential threats lying outside that model get ignored?

Public safety might better served be by a bug-bounty system, or by retaining several teams of outsiders to penetration-test a system like this.

But it will take some serious organization discipline to pull this off. Every software developer knows there's a twinge of embarrassment when the QA test finds a defect. Hopefully the NextGen team will be similarly embarrassed by the most ingenious of their pen-testing teams. And hopefully their organization will have the good sense not to punish them.

If you have content (not the entity using the handle "manigandham", of course, you "work in the online advertising space", so by definition you're not producing content I want to see) you can't afford to give away then make people pay for your content, period. It's a different world out there on the Internet, and it's not my job to tell you how to monetize your content.

Back in the print age, most magazines made most of their money selling space to advertisers. That's fine; readers paid the cover price (sometimes far below the publisher's cost to produce) and received ads (the bulk of the publisher's income) in return. Of course I'm oversimplifying this, but I'm not wrong.

Publishers today have access to essentially every eyeball on the planet for minimal cost; good for them! They can spread their messages to people who would have had no access to it 30 years ago (and 30 years ago, I was paying USD$12 to my local newsstand for a copy of Melody Maker; how much of that was to recoup the newstand's cost to get it from their distributor?). Their only need for advertising was to subsidize the cost of the content they actually produce.

The consumers have spoken; they have no perceived need for advertising. Lots won't understand that advertising is what actually pays for the content they read, but (and I really do blame the newspapers for putting all their content on the web for free at the start) content producers appear to be giving away their content for free. They "can't" put up paywalls because then they won't reach the maximal audience to which advertisers can peddle product. That's not my problem. I, as a consumer, can consume whatever is available to me (that's the other edge of labeling us "consumers", we're not your "customers" anymore).

Publishers can't have their cake and eat it too. If converting consumers to customers (possibly by cutting out their advertisers) is too expensive they're in the wrong business. I am indeed a user of Adblock Edge; I haven't purposefully clicked on an ad since 1997, have been disgusted by advertising since long before that, and now have a tool with which to remove that which I oppose. I've seen a number of sites that ask me to turn off my adblocker so they can make money; nope. I've seen a number of sites that refuse to serve me content until I turn it off; bye! You're in a global market; compete for my custom. Like I said, it's not up to me to tell you how.
