Improving executive function using transcranial infrared laser stimulation (2015)

Abstract

Transcranial infrared laser stimulation is a new non‐invasive form of low‐level light therapy that may have a wide range of neuropsychological applications. It entails using low‐power and high‐energy‐density infrared light from lasers to increase metabolic energy. Preclinical work showed that this intervention can increase cortical metabolic energy, thereby improving frontal cortex‐based memory function in rats. Barrett and Gonzalez‐Lima (2013, Neuroscience, 230, 13) discovered that transcranial laser stimulation can enhance sustained attention and short‐term memory in humans. We extend this line of work to executive function. Specifically, we ask whether transcranial laser stimulation enhances performance in the Wisconsin Card Sorting Task that is considered the gold standard of executive function and is compromised in normal ageing and a number of neuropsychological disorders. We used a laser of a specific wavelength (1,064 nm) that photostimulates cytochrome oxidase – the enzyme catalysing oxygen consumption for metabolic energy production. Increased cytochrome oxidase activity is considered the primary mechanism of action of this intervention. Participants who received laser treatment made fewer errors and showed improved set‐shifting ability relative to placebo controls. These results suggest that transcranial laser stimulation improves executive function and may have exciting potential for treating or preventing deficits resulting from neuropsychological disorders or normal ageing.
Why on earth would stripe pay a middle man like WeWork to manage their office and lease?! Stripe is looking at buying an entire building. I'm pretty sure they can handle a 15 yr lease just fine. And don't need WeWork staff to decide what their office kitchens need.

This is just the beginning. Start microwaving some popcorn because this will be quite a glorious train wreck to watch! Hopefully the negative impacts are economically isolated.
I'm not saying they owe open source. I'm saying they leverage an absolute ton of open source, they are deeply dependent on it. All their communication, infrastructure, software and services and processes are dependent upon open source.

If supporting open source with money is paying it forward, I think React & other endeavors could be called paying it sideways. FAANG get legal tender fit for any purpose, hundreds of billions of dollars in revenue, billions saved not licensing proprietary software, and what proportionately little code they give back is not legal tender for any purpose.

But again I'm not saying they owe open source. I'm saying they could fund it many times over and couldn't exist without it. One day they will pay it forward just by paying fair taxes on their massive fortunes. Today they don't even do that much.
While he's technically right, you have no guarantee that the value as a whole is written unless you use the proper fences or synchronize it in some way.
well I moved to completely different city in different country two years ago, on top of that I work from home 100% of time, on top of that I have two small children. do you really think I have energy for close friend? I am happy to rest in evening and not work during weekend, so I can spend more time with children. there is basically no time for friends of hobbies some people recommend to make friends (if I had energy in first place)

so you can count me as one of those 18% guys. it's just stupid not take into consideration other factors, it's very different for single and/or childless people and for married folks with children, I would like to see difference in statistics for these two groups

my present socialization is just reddit, Twitter and some other mother in playground I like to hang out
> implementation of secondary indexes is not cache friendly

Can you get into more details about this? What about the implementation is not cache friendly?
This take makes a very clear argument, but I think it's important to question that, as a company grows, it is generally "willing and able to deal with building owners directly" - a similar argument could have been made for the early days of AWS, when it seemed like a great way for startups to avoid managing low-traffic, scalable infrastructure, but redundant for companies that had the resources to manage their own servers. AWS has shown how successful a 'platform middleman' can be, even for very large companies.

WeWork is betting on taking a similar track - sure, companies _could_ decide they want to build out expertise in leasing and managing real estate space, but it can actually help them focus on their core business more by leaving it to another company that provides the 'platform'. The growth of WeWork's enterprise offerings and general awareness of how to pitch to mid- and large-size tenants indicates that growth projections are not pinned to a startup-driven economy.
A few years back, my wife had to go to the ER due to sudden life-threatening illness. They were getting ready to stabilize her (barely) and turf her out because of an issue with health insurance (my employer was happy enough to take the premium out of the paycheck but never informed the insurance). It took a lot of pleading to keep her that night. A young black guy might well have been arrested.

Right now I am dealing with fantasy bills from an ER visit a few months ago.

The whole medical-industrial complex can die right now. I have no sympathies for anyone in it. If they get assaulted in the course of work, they earned it many times over.
It is worth checking out the relevant chapter in Alice Schroder's Buffett bio. Amazing story.

Iirc, it took her six months just to get out of the USSR, across Russia, through China, then went on a cargo ship. It also covers how she got started which is just as interesting (she got sued for selling too cheap, she can't read, she can't write, etc.).

The stores are also unbelievably large. They seem to be 25-50% bigger than Ikea stores, which is incredible. Only in America (and possibly China in 2030).
Do Gitlab and such companies even have the volume of employees to show up on WeWork's balance sheet?

How many of those places have people working at co-working spaces anyway? As opposed to home?

Not sure that during a downturn companies, or even individuals will be more likely to go for paying for fancy coworking space... perhaps less so?

My understanding is WeWork is more likely to be MORE sensitive to an economic downturn compared to their competitors as their valuation will put more pressure on them to make money and arguably they might already be behind the bullet on that one.
That's why I carefully inserted my weasel words of "I think" ;)

Thank you for your contributions. Great information.
Author here.. It depends heavily on the workload. We have man years of optimizations for our CDN workload that we have been upstreaming to FreeBSD. See, for example, the other talk I co-presented regarding Kernel TLS on FreeBSD.

Does your work integrate pretrained LMs like BERT or GPT2?
> In 1989, at age 95, Mrs. B's family forced her into retirement. Unhappy with this and realizing that Buffett had not made her sign a non-compete agreement, Mrs. B started "Mrs. B’s Clearance and Factory Outlet" across the street from Nebraska Furniture Mart three months later.

> Two years later, "Mrs. B’s Clearance and Factory Outlet" was profitable and the third largest carpet outlet in Omaha.
This is no different from creating a book. Except it will be fully interactive. The original person will still die.
It's also a successful business in that their growth plans could potentially deliver real value and economies of scale (talking purely hypothetically here). There's a very big difference between a startup which is profitable but would be far more valuable if it could grow using investments, a startup which is premised on economies of scale and so which fails if it can't grow fast enough to take off from its runway, and a startup like Theranos where the tech did not and probably could never work regardless of how many customers it had.

Even if We would fail for lack of further investments (because it's type #2), that doesn't mean it was #3, a Theranos. In both #1 and #2, Softbank has a lot of leverage over Adam, and in both it's kind of a game of chicken: neither Softbank nor Adam want to see lack of cash cause We either permanently curtail its potential (#1) or die (#2).
Cool! Can it also let the user to send the result to a printer (I personally am interested the PDF virtual printer) or save it to a text file (if it's text)?
I'm not an expert, but you are correct in that there is no error correction here, and error correction is still a long way off. Around 2016, realizing that running useful quantum algorithms was a long way away and there needed to be earlier roadmarks for quantum devices to signal the progress, the problem of "quantum supremacy" was introduced. The goal is to find the problem with the _easiest_ demonstrable quantum speedup (regardless of usefulness). They proposed a particular sampling problem (running a randomly chosen quantum circuit that has output with a positive probability on many bitstrings, where the exact "speckle pattern" of the probability distribution would only show up if no errors were made when running the circuit.) As the circuit is randomly chosen, it can serve no particular use, except for verification that the computer runs correctly. Relevant papers for more info:

The BSD logo was created by one of Pixar's founders[1], and Disney now owns Pixar. Disney also has money. I'm sure deploying FreeBSD is well within their reach.

In the work we've done, the TLS crypto of bulk data is handled entirely in the CPU by the kernel via ktls. Please see the slides, specifically the data flow diagrams.
I wonder how this would compare with Receive Side Scaling (RSS), which you can use to pin NIC queues to cpus, and then pin the rest of the handling to the same cpu, avoiding a significant amount of interprocess communication. NUMA concerns may be more important than CPU pining within a domain though.
Yes, but not Transformer-based like these two, rather LSTM-based like ULMFiT

Really appreciate the comment. We are committed to making prisons places of rehabilitation. An important and proven aspect of re-entry and decreasing recidivism.
One thing I haven't seen mentioned: 'Friends' in your teens and twenties are often really about having someone to hang around with while looking for a mate. So you won't look like a lone loser at the club, or in social situations, or so that you get to meet members of the opposite/preferred sex through the group.

Once people get married and have kids, all of that falls away, and so do the 'friends'. You don't hook up with new people, because either they want partners to ride shotgun with them while hunting for a mate, or they are set up too. What's left are people you have a real connection with, usually people you were friends with since you were kids, and those few family members you can stand being around. For many, that is a small to non-existing group. What's left is your wife and kids, and honestly? The best company there is, IMHO. And I am not worried about what I will do when the kids leave and my wife divorces me, silly me.
>'That being said, had someone of my same race had not choose me over the more qualified candidate I would not be where I am today', //

That's clearly unfair. The insinuation is that only non-black people can achieve the best qualifications, which seems exceedingly offensive.

What was your intended take-away -- surely not "nepotism/racism are fine if you're black [in USA]"?
This is astonishing. Can you provide any more information or evidence of the prevalence of this practice?
She was also notoriously abusive towards staff and her family. That was the reason why her family forced her to retire initially (iirc, and I may be misremembering this, she only has one biological son...the other two married her daughters and they were, perhaps understandably, not keen to carry on after the sale because of the abuse).
What happens to wework when landlords one day offer leases directly to wework tenants? I’m not sure why landlords aren't doing that right now.

Use wework to fill the building, then go around them to get more cash by leasing directly to the tenants. Tenants might even see rents lower.
Yeah that's roughly correct. I actually hadn't found hetzner when I was doing my initial research but it definitely looks like I should be moving over.
With respect, a checklist with sixty different top level items isn’t going to help me.

If you could break this down into a maximum of eight different top level categories, and then eight or fewer sub-items, that might be a better start.

It’s okay for checklists to have more than eight items in it, so long as they are sequential in nature and you’re listing out the steps. At that point it’s more of a flowchart than a checklist, but you can call it what you want.
Studies like these are great for the popsci filter bubble, not so great for establishing credibility.

I'm biased and believe in contemplation as an overall life sustaining practice.

Lovely checklist:
- controlled, non-randomized
- small sample size
- validation by industry standard made up surveys and scales named with stupid acronyms
- super terrific vague conclusion: "A 1-month Vipassana meditation retreat seems to yield improvements in mindfulness, well-being, and personality, even in experienced meditators."

Imagine all the money and effort to get this published.

Earth to researchers: eating avocado toast in 108 seconds seems to yield improvements in mindfulness, well-being, and personality.

It took ten years to build up the 'Moon Shot' industry in the sixties. It would take at least that long this time to rebuild all of those factories and retrain the thousands of personnel to that level of expertise.

I am willing to state categorically that there will be no Moon Shot in 2024.
> "What happens if you're booked on a train from Company A and it doesn't run, and the next train is from Company B?"

In the UK, you can buy expensive, flexible tickets which are valid on any train and any reasonable route, or you can buy cheaper tickets with various restrictions, typically one or more of:

- Valid only on a particular route/operator

- Valid only on off-peak services

- Valid only on a specific train/time

- Must be purchased a certain period in advance (usually by the previous day)

However, in the event of significant disruption, and trains are running late or cancelled, an announcement is usually made relaxing the cheap ticket restrictions. At the very least, if you have a cheap advance ticket and your train is cancelled or delayed, then you're allowed to use it on the next available service, regardless of operator.

One common solution is to have another thread continuously prepare a bunch of empty buffers in advance, the audio thread just uses one of them, and after that is filled another thread writes it to disk. No locking is required, and no malloccing/disk IO happens on the audio thread.
I'm not disagreeing with the headline, I'm disagreeing with the content.

I do have a moral code, and I believe that everyone should. However, this developer implies that everyone with a moral code should align with his actions.
Right. In one case somebody worked out that Tay would repeat anything you wanted if you said “Repeat after me” first. Tay was just functioning as an echo, not taking on beliefs.
How would you keep track of that, and confidently identify people who have been banned?
And when she decided to rejoin, Buffett made her sign a non-compete agreement...at the age of 97 (I think)...which is surely a first. Iirc, it was a five year non-compete.
Correct me if mistaken but isn’t the goal of mindfulness meditation to accept the inner dialogue rather than fighting it?

For instance at one point as a child I had a conscience that would talk to me but as I grew older the voice passed into the background. Now my thoughts are the sort of jumbled mess meditators talk about.

So I don’t understand why developing the ability to hear and accept these other voices would be a detriment.
Because people prioritize their personal finances over company performance? That doesn't sound surprising to me.

This is also relatively new and it takes time for traditions to change. When it comes to the real world, you can clearly see this research in action, particularly in the world of software. There has been a shift from offering pure financial incentive (e.g. working in finance) towards more intrinsic rewards (mission-driven, autonomy, ownership, etc that most top-end software companies prioritize)
you have unlimited time when you are single, just join some activity and very to know people and it can work with someone, good luck finding time with family, especially with small children
funny enough.. my team probably killed off (one of anyway) the last tier 1 internet multicast deployments over the past few years.

Multicast has dataplane resource scaling issues and, frankly, CDN has become the solution to what multicast solves.
Thanks for sharing! Despite the fact that Shannon's "A Mathematical Theory of Communication" is so accessible, I find that most in our field (stats/ML) don't often think through information-theoretic tools in a "first principles way."

Yes, KL divergences show up everywhere, but they are not derived from scratch often enough. Maybe I'm stifled by my campus bubble though :)
>Actually there is.

statements of fact like that with regards to a fairly unexplored territory are worse than useless, they're damaging.

By what criteria do we know that this is a 'severe refusal to move on'?

Should we accuse people who peruse old photographs from their history of the same 'severe refusal'?

Why can't this AI idea be just yet another tool at our disposal for memory recall and recollection?

Why paint this as some mental ineptitude, rather than just an archival opportunity?

Most stores of data have possible consequence by their mere existence. What's different here exactly?

Would the idea be more palatable if, rather than the clickbait ideas of immortality, it was framed as a trained chatbot?
This idea has more holes than Swiss cheese, yet heck with it: remove layers of abstraction from entire systems—hardware to software and everything in between.

Each layer consumes additional resources which ultimately consumes energy.

In today’s environment, we try and abstract anything and everything away. From the services we use to the software we create and if we were to take a look at those dependencies, that graph would be stuff of nightmares.
If you want to be durable in a downturn you need resilient or countercyclical industries leasing from you.

If they had a bunch of boring utility companies and collections agencies leasing from them then we might be onto something.

I think the Facebook IPO was done for one reason only; public relations.

As is the case with toxic discourse on his website, the nonchalant attitude with private information, Zuck loves to steer clear of taking responsibility for anything. The IPO allows the message to be: it's not my personal responsibility, I'm merely the CEO of the company.
This sounds like something I'm going to like.
My uncle, who once taught ancient greek at johns hopkins, explained to me the ancient greek understanding of sacred and profane was that profane was the normal relationship with reality, and what was outside of that was sacred. The example he gave was that in order to be executed, prisoners first had to be made sacred, so that killing them wasn't a transgression.

Honestly, I was hoping for something like the `tree` command. I've implemented that algorithm before, but it was painful and not portable.

These trees are definitely cooler and more complex but maybe fewer use cases. Once you start dealing with more than a few layers, the output is going to line-wrap in a terminal. For larger trees, DOT [1] is probably more suitable.

I moved from Omaha to the Denver/Boulder area two years ago and besides the Henry Doorly Zoo, I miss Nebraska Furniture Mart the most.

NFM is a great place to buy pretty much anything you want to put in your house. Mrs. B really knew how to make a business work. The only weird thing is how antiquated their computer systems are, it's amazing they are so profitable with 70's era technology running the business.
How do you know in advance who they are?
Imagine that random, unremarkable things involving people from Arkansas occasionally got blasted across every newspaper and forum in the US. And everywhere you went, you saw people saying that this must be a plot from Arkansas' governor to take over the US, and everybody from Arkansas is a government spy, that Arkansas' culture of deception meant that you could never trust anybody from it, and that true patriots spent every day fuming in hatred at Arkansas and its people.

If you were born in Arkansas, this would be all be clearly crazy, because you would know that your family in Arkansas are ordinary human beings, not heartless government spies. And it would be rather alarming, even if you had moved out of Arkansas, and hated its current government, because you would be next on the chopping block.

It would be even more disappointing if, when you tried to argue otherwise, you were dismissed without a thought by the same Arkansas paranoia. That's how witch hunts work.
I guess you just clarified why this is bullshit and why quantum supremacy still doesn't exist.
