dpweb··on On the Existence, Impact, and Origin of Hallucination-Associated Neurons in LLMs
We don't understand the brain. We fully understand what LLM are doing, humans built them. The idea we don't understand what LLMs are doing is magical. Magical is good for clicks and fundraising.
dpweb··on JPMorgan CEO: "I don't care how many people sign that f—ing [WFH] Petition"
Been WFH for many years, but I can understand why some companies prefer (demand) in office. Sorry, but unless its written into employment law, no-one has a "right" to it.

I would think this could be a perk that companies could use to get an advantage in hiring. Although, maybe those who it appeals to on the whole may be lower performers?

Would love to see some real data on this.

dpweb··on Teen on Musk's DOGE team graduated from 'The Com'
I’d also distinguish between the hacker to gets access to a forbidden system out of curiosity or for a challenge, from a person who pays a ddos service to attack someone they don’t like (one of the accused actions of this kid).

The latter displays no competency in hacking or cybersecurity, only the attempt to harm another.

My concern in their access to secure government systems is not their hacking competency (which has not been demonstrated), but their sociopathy which has.

dpweb··on Most iPhone owners see little to no value in Apple Intelligence so far
Maybe because nobody really asked for these things gemoji and "rewrite my email".

Neural nets are a foundational technology there should be a ecosystem of apps based on it. People pay 1500$ for an iphone because it has apps, not to call and text people. I think its coming and Apple can't just NOT do AI, so I get it, but it will take a little time.

dpweb··on Deep Live Cam: Real-time face swapping and one-click video deepfake tool
Facinating software although I hope the idea "we're gonna rely on people to be good humans and DO THE RIGHT THING" is quickly abandoned and instead there is just as robust development of detection software that goes along with newer and better deep fake tools.
dpweb··on 40-Year old BASICA utility code for teaching
3.5" disks, nice. We were still on 5 1/4" in high school in 87-88.. True floppys! I remember thinking 3.5" hard disk - wow the technology :)
dpweb··on Report on the role of standardized test scores in undergraduate admissions [pdf]
Increasing enrollment means increasing faculty.

Maybe controversial but I really believe this lowers overall standards. You just can't find enough faculty to meet the high standards.

Look what happened when tech blew up - they hired like crazy. I'd argue the overall level of programming skill went down.

dpweb··on Report on the role of standardized test scores in undergraduate admissions [pdf]
Always felt that the ability to think was indicative of academic success.

But also a good SAT for (those not naturally brilliant = most of us) also a positive indication of the student work ethic (to study for the test).

The problem I believe with the disadvantged students argument, which I believe to be a very real problem - is that lowering the standards wrt the test scores - is just a bad solution to a real problem.

Poor students do sit at a disadvantage - but the fix is much more difficult and complicated, and involves that child's entire life experience until they become 17 or 18 y/old. No one has a handle on how to fix it.

I get the feeling smart + hard work will come back into fashion when it comes to academic opportunities.

dpweb··on You are never taught how to build quality software
Testing and QA is great and all however there is something to be gained from a CompSci education besides making more money for the company. It can be enjoyed just for the sake of it.

Binary arithmetic doesn't make dollars for your bosses, but its fun. That doesn't make it less significant.

dpweb··on Life lessons from a 44 year old (2022)
In 50+ years I've learned one thing.

When you have a kid. Drop EVERYTHING in your life, take off (completely) from work and spend your days with them. For at least a month or two. Make breakfast, watch little kid shows, all that.

Yeah money, but you have decades to earn money. Those couple months you won't get back.

Donors like that threaten to pull their money when you don’t behave. It’s why they donate. There is no such thing as a donation.
dpweb··on The Truth about College Costs
Have paid school tuitions for 15 years now, pre-K to 12, and in 2nd year of college now. Some thoughts..

College is just like private K-12 - there is no set price, it's indexed to your income. They have to set a high list price so the wealthy can pay that and they aid those w less income. Don't forget about car and health insurance!

Do every single aid and scholarship app you can find. Use the appeals process especially if you have extenuating circumstances. Read the rules carefully about which assets/income is relevant.

If you're divorced (I am), read the rules carefully about income and asset reporting in those circumstances.

It's not that you're paying for the credential, you're paying for the experience, education, and credential. Just the credential is the expensive part of it.

Example, I've been a DJ (just for fun) for 30 years. Just saw an ad for DJ school. Even if they wanted to be a professional DJ (ok, if that's your dream), I'd NEVER pay for my kid to do it. There's a legit cost in educating anyone. But the credential is worthless. A university degree has some value. Of course, you can learn ANYTHING online for free. Anything. The credential is the expensive part of it. So make sure it's a credential with value.

You may have to say NO to your kid(s). This is VERY tough. But weigh your options carefully as spending your entire retirement fund on college (mostly for the credential) is a dubious proposition.

dpweb··on We reduced the cost of building Mastodon at Twitter-scale by 100x
Built some log databases and back end frameworks myself with some of the same concepts. I applaud the creativity in rethinking how back ends should work. Please now do frontends next! :)

"But it's not a fully functioning 2023 Twitter!!!" I think some people miss the point. This is not about hey we built a Twitter clone. This is about a POC for a novel app architecture.

We need to be constantly examining and re-examining our thoughts about the best way to deal with distributed systems, scale, developer workflow. Even inventing new ones.

dpweb··on If Web Components are so great, why am I not using them?
Can be reduced

    customElements.define('like-button', class LikeButton extends HTMLElement {

        onClick() {
            this.innerText = 'You liked this'
        }
    })
dpweb··on Fitch Downgrades the US Rating to 'AA+'
I don’t see congress doing the responsible thing and dealing with the debt. Not to mention, there isn’t as much that can be cut from discretionary spending as you would think. Any meaningful cuts decimate everything outside of defense.

We’re not (in my option) going back to zero interest rates, so interest will make balanced budgets impossible to achieve.

Also don’t see much appetite to cut defense as we’re aligning to have China and Russia as enemies.

Rather I think we’ll resort to more of the Fed buying up the debt who can remit the interest payments back to the treasury.

I could see a scenario where they even just retire/redeem treasuries so the debt just goes away. The downside it’s inflationary but also does this erode confidence in the system where things are (even more so) centrally controlled.

dpweb··on Book Review: The Laws of Trading
There's always a plethora of misinformation about trading, so here goes.. Retail and institutional is the difference between playing in a casino and being the casino.

It's important to understand - on the whole - he average probability of guessing the direction of a trade is 50/50. Any obvious (and virtually all non-obvious) edges, arbitrage for instance, are removed by the market participants. That's what a market IS.

In that respect, 'random walk' is correct. However, that does not mean all participants cannot expect profitability over the short or long term. Which are also themselves, very different things.

For retail traders, transaction cost (commissions + bid/ask spread) make it a negative expectancy.

In fact, bid/ask spreads and commissions ARE PRICED right at a level to remove any positive expectancy, but leave the APPEARANCE of a possible positive one.

Getting that up just a couple percentage points to a positive expectancy is difficult in the short term, and VERY difficult over the long term. Not impossible. That's why about 70-80% of active retail traders are losing overall at any given time.

For firms, order flow and much lower transaction costs make for a positive expectancy. The value of order flow alone is responsible for the zero-commission trading industry.

Skill isn't the issue. The trader with skill level at lose a little or break even trading - from his bedroom - would very possibly be winning on the big banks trading desk. Even if executing the SAME trades they were at retail. More so, the more frequent the trading activity.

So if big institutions have a built in edge why do they sometimes fail? Easy, they still sometimes make stupid bets (ie.. Silicon Valley Bank's bond bet which killed it).

dpweb··on Swiss capital city wants to test controlled sale of cocaine
That’s what we need another highly addictive legal substance that’s harmful to health and can buy in every store.

Making it illegal does not eliminate its use. It reduces its use. 63% of Americans drink. 1.7% use coke (have in the prev 12 months).

dpweb··on Instead of your Life's Purpose (2021)
After reading the terrific "Denial of Death" I asked a few friends if they felt dread knowing that would one day die. They said they don't worry about it and I cannot relate. Seems to me the entire meaning of life and the point of it all is to just LIVE.

It follows that knowing of your own eventual annihilation must be terrifying. Sure you can take refuge in false delusions or just ignore it. But if you're not afraid of death, are you really living? Are you really respecting life properly when you're not terrified to lose it?

dpweb··on Ask HN: Does attempting to finish my CS degree make sense?
Go for it.

If there are mental health issues - find help - not everyone even professionals can necessarily help - you may have to try different people, but it can get better.

dpweb··on Fed hikes rates by 0.25 point despite recent turmoil in the banking sector
Inflation is also good for those that own assets as their relative value to dollar increases.

Everyone has a mix of: Debts, money they've loaned to others, amount of assets owned, and amount of dollars owned and wages (recurring income in dollars).

So, inflation is most harmful to wage earners with few assets - and most helpful to non-wage earners with many assets.

Increasing wealth disparity between workers (most people) and those who own the most assets. Those who own large amounts of assets largely don't own dollars - they own real estate, securities, etc..

The bank issue is a strawman - simply a matter of SVB (and others) making bad interest rate bets and losing.

dpweb··on Research shows we can only accurately identify AI writers about 50% of the time
The quality of an AI should be judged on its ability to detect AI, or itself.

If it can’t then the quality of AI is exaggerated.

dpweb··on SVB collapse: Peter Thiel’s role scrutinized as spark of bank run
HOW do you have hundreds of portfolio companies with uninsured millions in a bank. Please can some venture capital expert explain? Tell me it's not just hubris.
dpweb··on SVB shows that there are few libertarians in a financial foxhole
Glut yes, but that not the cause - nor was the bank run. Simply, hubris.

They bet billions on zero interest rate policy and didn't hedge that bet.

Glut or no glut, would have failed just like LTCM or any other huge bets that failed to consider tail risk.

dpweb··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
VC insider types won this one in some sense but at the cost of some credibility (those most hysterically yelling om twitter at least)
dpweb··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
Not much of a choice. Guarantee of the system takes highest precedence.

Although this problem was caused by bank malfeasance and yes this does imply de facto unlimited insurance, unlimited depositor insurance is kinda the whole point and is not itself a bad thing.

Yes, moral hazard is a huge consideration, but I don’t see depositor protection as encouraging future failures of this type, by encouraging bad risk taking by mgmt.

Rather, if banks bet their customers money unhedged on endless zero rate policy, as SVB did, there should be regulations that prevent it. Trace back to lobbying to exclude SVB from dodd frank regulations also at the heart of the crisis.

dpweb··on Yellen says government will help SVB depositors but rules out bailout
It’s from the hubris and excesses of recent SV culture.

And most Americans have no conception of being able to have 250k in a checking account.

The vengeance attitude can be taken too far however but as depositors are ultimately made 80-100% whole seems a reasonable outcome.

Bottom line uninsured means uninsured. Read your contracts. Although shouldn’t be angry if they can be made whole.

dpweb··on Bill Ackman: The gov't has about 48h to fix a-soon-to-be-irreversible mistake
Enjoy your weekend.

Obvs a prediction, but while the limit is 250k - the FDIC will act to protect depositors with higher amounts - probably a private aquisition of some kind.

May be worth upping the (advertised) 250k insurance limit, as the de facto amount is already higher.

dpweb··on FDIC Takes over Silicon Valley Bank
May be nice for an acquirer. Roll those long term bonds into very short term treasuries - take that big loss now - and earn 4% going forward.

Rates will eventually top out - they just had made a very bad bet at 1.5%/10 yr.
