> Funnily enough the SR71 at Mach 3.5 had a better mpg than a Boeing 747 below Mach 1.

The SR-71 had a maximum takeoff weight of 140,000lbs.

The 747 has a maximum takeoff weight of 735,000-910,000 lbs, depending on model.

That helps quite a bit for the former using less fuel per mile.

Koi: A CLI Assistant Built with ChatGPT
I am currently researching how we can use AI at my current employer. We did not have any AI knowledge to begin with.

I was quickly able to write a web scraper using Python in a few hours by employing ChatGPT. I hadn't touched Python in like 12 years before that day. It wasn't just a generic scraper. I asked ChatGPT to fine-tune it to a). crawl pages belonging to a certain domain b). save data inside a specific directory with specific filenames.

Before that, I asked it to write unit tests for a React component. It did and I got 100% code coverage for that component. Our manual test suit had around 87% code coverage for that component.

Having said that, it constantly requires human intervention to judge if the produced output would work and how to integrate a piece of code produced by it into the actual projects.

This is true. The basics are required for ear training. But once you get past the basics (reading music, intervals, identifying chords), I don't thinking going much past that is necessary.

I think I'm incorrectly assuming people want to take it past the basics when they say they want to learn music theory.

This is nonsense. No farmer or rancher in Texas wants feral hogs, and no one in Texas tries to promote feral hog populations. We have something like 4 million feral hogs. The problem is that avid 1 hunter can take out 20-30 in one night, but they don't go out to do it every night, and there's not enough feral hog hunters to make a dent.

Feral hogs cause enormous amounts of damage, and there's no hope of hunting or trapping them down to manageable numbers much less zero.
The second niche as a rule of thumb pollutes-more-than-God already(0)

I am skeptical that lifting barriers to them polluting more would land any type of net benefit given that ultra-luxury products such as said jets don't tend to land outsized downstream advancements than let's say, funding basic sciences such as what Boeing or Airbus are already doing

If it could be proved that things like faster private jets or faster planes could benefit in a sizeable and proportionate way to the general public, then yeah I would be in favor of this too, but as it stands I don't find the available info compelling, I'd rather them to pay more taxes

Yeah this is a good point. The military was never capped by speed limits nor fuel costs or pollution limits. And even they didn't go faster than 2200mph as far as we know.

Which either means there was no reason to figure out how to go faster, or they just couldn't do it. If the former, maybe with commercial pressures there would be a reason to go faster, but that's unlikely. And with the latter, well I'm not sure a commercial entity would out-innovate the military-industrial complex.

Way too much focus on the HOW and not the WHAT
I think this principle is most useful in the negative, i.e. not calling oneself negative things.

I recall seeing someone (I think in NY) trying to revolutionize math education by making certain that the concepts were easily graspable enough that students couldn’t not get it. His idea was that if someone labels themselves as “not a math person”, it becomes a self fulfilling prophecy.

The labels we use to describe ourselves and others are very powerful and can impact our mindset and actions. We should be careful to use that to our advantage.

Far far less. Alpaca-7B's compute cost was around $60-$70 for Stanford and around $0.60 (yes 60 cents) for equivalent fine tunes using the Parameter Efficient Fine Tuning (PEFT) strategy of Low Rank Adapters (LoRA).

The repo above can be replicated for similar costs. Easily less than $10 for up to 30B using LoRA (which requires only 24GB of VRAM for 30B/33B and smaller).

> The problem is that most of us didn’t do the only X that matters, which is to actually write. [...] Writers who don’t write seems like a niche phenomenon of a narrow and privileged set

Nah, I think this is super common across titles that people romanticize, mainly in the arts, since there's no real barrier to entry. (Unlike, say, claiming "I'm a lawyer" or "I'm a doctor.") I've seen tons of people say "I want to be/I am a musician" and then spend a bunch of time watching YouTube tutorials, hanging out in musician/producer Discords, etc. and not actually, you know, making music.

For a lot of people, "I want to do X" actually means "I want to have done X," and then reap all of the benefits that comes from that: the sense of accomplishment, the fame, social media follows, whatever.

These days I'm usually very suspicious of people who make big public pronouncements about how they're starting X task, whether that's going to the gym, learning guitar, building something in Rust, or whatever. If you wanted to do the activity, you'd just do it without all the pomp and circumstance. Every time I've seen a friend on social media announce they're going to start a grand new adventure, they fizzle out after a month or two. The ones who get shit done will show up to a party looking amazing and casually mention, "Yeah, I've been hitting the gym."

I didn't read the full paper, which is very interesting, but on systems with proper ECC configuration[1], the scanning portion of the process would generate a huge number of machine check exceptions. Having run a large number of ECC enabled machines, high volume ECC correctable errors are disruptive to normal processing, and the machine goes out of service for repair quickly. If I were running a multi-tenant cloud, knowing that RowHammer is a thing, I would migrate the VMs on a machine throwing correctable errors, and also track the customers. VM migration during scanning is going to result in inconsistent data, and successful exploitation seems unlikely. Tracking the customers, allows one to prevent repeat rowhammerers from accessing your systems.

That said, it's still very interesting and many systems have improper ECC configuration. ECC without reporting isn't going to mitigate RowHammer; nor will it help to have ECC with reporting, if the reporting is ignored, etc.

[1] I didn't make it to their system configurations, but I did see their description that only one system under test properly responded to errors, by logging errors, and crashing on uncorrectable errors.
True. An average city bus gets 7 mpg; an 812 Superfast gets 13mpg.

The bus wins when carrying 3 or more passengers besides the driver. And in a city with dedicated bus lanes, the bus may win for route speed, too.

On November 30, 2012, amid a friendly back-and-forth about lunch plans, Hibino e-mailed Fitzsimmons an attachment that he described as “really hilarious if I do say so myself!” Hibino explained, “I did it for the amusement of our team, and of course, you guys”—presumably Harvard admissions officers—“are the only others who can appreciate the humor.” The joke memo had been written on Harvard admissions-office stationery, during the earlier investigation. It was purportedly from an associate director of admissions and parodied the admissions officer downplaying an Asian American applicant’s achievements. The memo denigrated “José,” who was “the sole support of his family of 14 since his father, a Filipino farm worker, got run over by a tractor,” saying, “It can’t be that difficult on his part-time job as a senior cancer researcher.” It continued, “While he was California’s Class AAA Player of the Year,” with an offer from the Rams, “we just don’t need a 132 pound defensive lineman,” apparently referring to a slight Asian male physique. “I have to discount the Nobel Peace Prize he received. . . . After all, they gave one to Martin Luther King, too. No doubt just another example of giving preference to minorities.” The memo dismissed the fictional applicant as “just another AA CJer.” That was Harvard admissions shorthand for an Asian American applicant who intends to study biology and become a doctor, according to the trial transcript.

It's pretty disgusting what you can get away with as long as you follow the right politics.

More like $50 or even $5 or less for the cloud GPUs. Alpaca-7B's compute costs were close to $50 and that was before the 100x cost savings of using LoRA.

A 4bit LoRA fine tune of this project would cost less than $5 to train even up to 30B/33B.

Didn't explore much, but it seems alpaca-lora has better results for coding tasks. One example I've used was: "Implement quicksort in python.". This is the result with Code alpaca:

def quicksort(arr):
if len(arr) < 2:
return arr
else:
pivot = arr[len(arr) / 2]
left_index = 0
right_index = len(arr) - 1
while left_index <= right_index:
while arr[left_index] < pivot:
left_index += 1
while arr[right_index] > pivot:
right_index -= 1
if left_index <= right_index:
temp = arr[left_index]
arr[left_index] = arr[right_index]
arr[right_index] = temp
left_index += 1
right_index -= 1
return quicksort(arr[:left_index]) + [arr[left_index]] + quicksort(arr[right_index + 1:])

Alpaca lora result:

def quicksort(arr):
if len(arr) <= 1:
return arr
pivot = arr[0]
left = [arr[i] for i in range(1, len(arr)) if arr[i] < pivot]
right = [arr[i] for i in range(1, len(arr)) if arr[i] > pivot]
return quicksort(left) + [pivot] + quicksort(right)

Shorter and much cleaner, not to mention it works (code alpaca version is broken). Also it matches what ChatGPT generates for me.
A lot of electrical engineers don't know much about how C++ (and C for that matter) actually works.

The real reason to use C in embedded programming is that "vendor_forked_gcc_from_10_years_ago" is your only compiler on most platforms, and almost certainly does not support C++ or has some bugs in its C++ compiler implementation.

Not the tool nor data scientists, but advertisers are salivating at the chance to even further improve their microtargetted campaigns. If they can deliver ads to you for a specific product _at the moment you need it_, their revenues will explode.

Consider this hypothetical conversation:

> Oh, Tina, I'm feeling hopeless today. Please cheer me up.

> Certainly, Michael! Here's a joke: ...

> Also, if you're feeling really sad, maybe you should try taking HappyPills(tm). They're a natural mood enhancer that can help when times get tough. Here's a link where you can buy some: ...

If you don't think such integrated ads will become a reality, take a look at popular web search result pages today. Search engines started by returning relevant results from their web index. Now they return ad-infested pages of promoted content. The same thing has happened on all social media sites. AI tools are the new frontier that will revolutionize how ads are served. To hell with all that.
I've been reading through the proposed C23 spec. Looking at what's happening with enums, it's amazing how suddenly a simple feature became a far more complicated one. I read the spec on enums over and over, and still don't understand it.

This has been happening to me for the past several months.

1. Cigna will not tell you for any reason, why the claim is denied

2. Reps will not help at all other than "Oh I see the issue, will reprocess" which often just results in another denial

3. The issue that a helpful rep finally disclosed: Cigna's own claim form for providers has a box that is overloaded for procedure code and equipment code; apparently the CPT code for therapy is the same as the equipment code for injections.

So one claim processor decided that the claim was for injections and denied it. Then every subsequent claim has been denied under the same reason.

4. At this point the only option for me is for my provider to appeal every single claim (which takes months), as this is the only way to get someone to actually read the claim and make an intelligent decision.

An absolute nightmare :(
Question for anyone who uses this or similar knowledge management tools. Besides a fancy interface and visualizations, what do you get?

I really want to like this tools, but I've found they all suffer from some major problems: It requires a lot of detail to capture thoughts accurately. I've always ended up in a situation where:

* I can capture the "complete picture" of my thoughts, but the notes/visualizations are basically useless. The details are missing.

* I cycle into the details, then loose track of the bigger picture.

Combine this with the fact that all of these things are basically fancy notebooks, I find they don't offer enough opinion to be useful.

This is pure anecdotal, but since getting C-Diff a few years ago, whenever I get sick my gut feels much better (same with my skin). When my gut starts hurting again, and my eczema flares back up, I know that I'm almost over it and should slow down the vitamin C. And of course, my anxiety/stress also flares up.
A sonic boom is quite loud and will shake all the windows of every home across a state (though only a smaller section of the state if it is large like California).

I have not heard them since the Space Shuttle was retired.

I agree with the forever part in theory. However in politics (and law) if you leave a door slightly open, then people are incentivized to open it wide open and “get around” various rules.

Permanent “for forever” laws and never that. They are forever until someone changes them. That’s more binary and easier to reason about than “this sonic boom is better than that sonic boom so it’s ok, and it the 1980s already so let’s have at it!”. You set some threshold number, then the politics is about the number not the booms themselves really.

If technology has truly advanced enough, people will change the laws. Done.

Now as an engineer, I prefer the threshold. But it’s so much easier to change that. You start a company in 1980 and have so much better tech after 10 years in 1990, but it doesn’t materially change things enough, so you shut down or try and change the threshold. What do you do?

Some learnings from circa 6 years in startups, applicable to startups:

1. Only listen to people who have walked the walk. Many people with limited tech exp will try to advise you on how to build products/tell you what to do, don't listen to them unless they've done it successfully and it was they that did it -- not some other team they 'advised' or 'managed'.

2. Write stuff down. Promised a raise at X funding point? Write it down. Bring it up and don't let it go.

3. Avoid surrounding yourself with people who sound corporate unless you want to sound like that.

4. Be careful about hiring/working with big co folks for small companies/startups. They often bring politics etc. in and seem on average to be less creative. This is a sweeping generalization and a bit harsh, but basically if you want to be involved with startups, associate with people from startups. Build your network around that.

5. Be careful with first time founders, and
see if you can get a gauge on their empathy. A good way to do this is invite them out to lunch and see how they treat the wait staff.

6. Build side projects and don't be afraid to look stupid/ask questions. That's how you get to be the best.

If you look at Peloton’s financial statements, you’ll see that your assumptions are off. For one thing, music costs are significant (Peloton had to settle a $200M law suit for not doing it right).

Yes, some costs are fixed so with more subs you get higher profitability but that’s really different than charging for something that doesn’t have a variable cost.
