OldSchool··on Heat pumps can't take the cold? Nordics debunk the myth
The 240V electrical isn’t as scary as it sounds; individually, the hots are no more “hot” relative to ground than a 120V hot (still demands respect!)

Certainly it’s not for everyone or even every engineer but I guess my point was that if you’ve already done most of these things yourself it’s not a huge leap to DIY your own HVAC install compared to the financial incentive, especially if your house has more than one system.

OldSchool··on Heat pumps can't take the cold? Nordics debunk the myth
The HVAC industry in the US enjoys massive gross margins on this equipment. Prices are supported primarily by licensing laws.

You can't legally break into the business, but DIY on your own house is entirely possible: the equipment is available for 1/4 to 1/3 of the "installed" price and some of the more climate-friendly refrigerants do not require an EPA license to purchase.

Yes, the work involves electrical, light plumbing and welding, a specialized tool or two, attention to detail, and definitely physical labor, but for a lot of engineers that's just fun stuff to do on a weekend - really fun stuff when you save over $10K per installed system (at the 3-5 ton unit capacity level.)

OldSchool··on Great Hacker != Great Hire (2004)
Anyone else see the irony in all of this hacker-bashing on this site called "Hacker News?"

Not just in this particular discussion, but overall a shift away from talking about individual, inspired and sometimes entrepreneurial creativity toward how to pass a FAANG-style interview or have better standups and corporate culture.

OldSchool··on Ask HN: New Monitor: Ultrawide or 4K?
If you're not using a discrete GPU, that addition very possible will open up some more HiDPI resolutions for you. With a modest RX-460 (recognized in 10.13+) I get a variety of formats starting from a 2560x1440 layout over 3840x2160 pixels, and incrementally more spacious, all still over 3840x2160 on the wire, all with excellent HiDPI rendering. My intel graphics iGPU delivers just the limitations you described.
OldSchool··on How I replicated an $86M project in 57 lines of code (2017)
What would really be impressive would be a story entitled,"How I sold 57 lines of code for $86M."

I'll suggest that the escrow route is an alternative to agreeing to indemnification in a simpler form; I can't imagine a situation where having both would be of benefit to the seller at least.

I think ideally escrow would nicely encapsulate risk for a seller and ramp it down over time. When applied to cash it could create tax issues if a payment is recognized as income in one tax year and only becomes available in a subsequent year. For shares received by exchange for existing shares structured as a merger, this is likely solvable. If a selling party holds only stock options though and is issued shares on closing, again, my initial guess would be that would be deemed a "taxable event." Another aspect of escrow is that it eventually requires sign-off from the buyer to release it to you, effectively giving them control of your proceeds that they might attempt to exercise outside of the original intent of the escrow.

So, as for handling your windfall during the indemnification period, yes, purely the simplest approach would be to hold the proceeds in the most risk-free way until your indemnification period ends.

This is however, again complicated at least by tax implications if you need some of the money to pay taxes due on cash received in the closing.

Furthermore, there is a strong argument for using some cash to hedge against a decline in the value of shares received (if any), simplistically illustrated by purchasing put options on the acquiring company's stock, since you're forced to hold it throughout some inevitable lockup period. Put options on a reasonably closely-correlated financial instrument might also be viable if the acquiring company isn't so large as to have an active options market, since public stock prices seem to move broadly, barring any company-specific failures.

To put some entirely fictional numbers to the hedging argument, imagine you're obligated to sit on $10M worth of public stock for two years and you could spend $250K cash today to gain a significant level of protection against a drop in the share price. After your two-year wait, you either have $10M or more in stock if the price held or rose ($250K is gone but you spent it on insurance of a sort) or perhaps the stock dropped 80% and you now have $2M in stock but another $4M made back from the put options you bought, so while $6M pre-tax isn't $10M, it's a lot more than $2M.

OldSchool··on How I Sold My Bible App Company
I'm surprised this isn't more discussed in the comments. It's a major element to consider when you're selling your business. He correctly identified it after all, as a potential deal breaker.

You're selling something, so in an acquisition you will have to represent and warranty what you actually own and you're selling. This sounds simple on its face, but technology isn't nearly so well-defined and legally sorted as, for example real estate.

In software, even if you are 100% certain you can transfer all of the code and there are no potential content copyright issues or latent prior agreements by yourself or other sellers, current/former employees who think they own something, etc, you still have at a minimum, a hard-to-quantify "Sword of Damocles" in the form of thousands of potential patent claims hanging over you, trolls or not, it doesn't matter in a sale. As in business itself, the bigger the money involved, the more visible you become to potential claims.

A publicly-traded buyer is likely to be less flexible on terms, but in any case you as a seller have also to consider that in a sale, you're most likely going to be forced to shift liability from your corporation to yourself personally. If you're prudent, as this seller was, you realize this creates a time period increased personal risk, despite your increased assets. Keeping this period as short as possible and limiting its scope and magnitude is your objective.

A few limitations I can vouch for making it past public company scrutinity are 1. any dispute costing less than $X are not your responsibility. 2. a maximum liability limitation equal to the purchase price in cash / shares (in case share prices drops) 3. a time limit of two years or less. 4. escrow of a portion of the purchase consideration (shares and/or cash) as a warranty cap for the duration of the warranty, perhaps with release/reduction over time. The tax treatment of this arrangement would have to be considered carefully.

Finally, it's worth noting that insurance for an acquisition deal may be available from big name insurers, likely for some low single-digit percentage of the deal value. However, their legal department will undoubtedly be more sophisticated in this area than your counsel, so at its worst insurance gives you little more than a contract with an insurance company over which to sue, likely at great cost.

Overall, as lawyers always say, "it depends." Unless the deal and/or your resources are immense, likely it is a problem with no risk-free solution. If you're young and have nothing to lose, risk is an easier choice. For everyone else, all you can do is optimize based on present knowledge.

OldSchool··on How to Legally Own Another Person [pdf]
All of his books have been worthwhile in some way. "Fooled by Randomness" is a great place to start. Its effect of exposing the lack of objectivity in many commonly-accepted beliefs that rely heavily on perceived cause and effect can add maturity and humility to your own worldview.

Ironically, my only complaint might be that Taleb seems to get a little more self-congratulating by anecdotally revealing the lifestyle he is able to enjoy as you progress through his series of books. Perhaps this is more of a style device to broaden the books' appeal.

Whatever the case, the perspective you can gain from his writing is worth the time.

OldSchool··on Porsche 911: 52 years of staying true to its roots
Thanks for commenting. Yes, the A/C is useless (pre-1984) then almost useless until the 964 and the 993 got it right.

As for a $10K repair bill, it's certainly possible, especially if you recently bought the car and/or get hit with some internal engine/trans problems.

These air-cooled 911's seem to be worth keeping on the road at least. There are many examples of other still high-end cars that just depreciate relentlessly until the last owner gets hit with a repair bill that's more than the car is worth and it goes to the junkyard.

OldSchool··on Porsche 911: 52 years of staying true to its roots
If you appreciate great engineering as well as design, any one of the air-cooled cars is a remarkable car. I think most will agree however that the 2.7L engine was a low point in quality.

Yes, many completely ordinary cars today can match or out-accelerate a lot of the older cars mentioned in the article but that is only a single measure. If you're a "car person," you owe it to yourself to spend some time driving a 911 so that you can truly map that image to a physical experience.

That said for the 911, each of the cars that enthusiasts tend to love has its own character. You can give them all very similar performance specs on paper and driving something American, Italian, or German will still be a completely different experience; overall, the fastest car will not necessarily even feel the fastest; the slowest car that you can consistently drive the hardest might prove to be the most fun to drive.

OldSchool··on American Electronics Hobbyist Census [pdf]
Yeah, I'm going to "guess" that as late as the 1970's at least, almost 100% of male children succeeded at blowing up stuff on purpose, whether or not they were electronics hobbyists.

OldSchool··on Silicon Valley Then and Now
No doubt the Valley will survive and thrive. However it will continue its path toward the business culture lead of Hollywood: further concentration of power and capital, more emphasis on acquaintance-level connections (something innately technical people don't often do naturally), and an ever-increasing cost barrier to entry. Hollywood of course has had the time to take this to the extreme, but the "work for free and hope to get noticed" effect is probably already upon us. I have to wonder how many startups are formed now with the intent to turn a profit from operations, rather than simply on the hopes of a large acquisition after obtaining some measurably significant social relevance.
OldSchool··on God's Lonely Programmer
That's correct as I recall.
OldSchool··on God's Lonely Programmer
Ticketmaster in Phoenix, AZ - early times - here's a little anecdote about the bizarre culture I saw there circa 1989-90. I applied there, having an EE degree already and I was called in for an interview. The initial interview consisted of what was more or less a battery of IQ tests. There must've been 30 of us initially. Soon only a couple of us were left after everybody else was dismissed. Apparently having passed this somewhat offensive process, they took more of my time and scheduled me for a second interview another day. I don't recall any names or faces, but there they offered me a job and mentioned some "genius" guy I'd be mentored by. Before I had the honor of meeting this guy we started talking money. The "pay?" $8/hour... Even 25 years ago that was less than half what a freshly graduated engineer could easily get anywhere else in a corporate job. That alone was enough for me to politely decline the offer, but the management attitude and culture was also repulsive. I wouldn't be surprised if they were exploiting this guy at the time and he may very well have been their "genius."
OldSchool··on How does a fighter jet lock onto and keep track of an enemy aircraft? (2013)
Thanks for pointing me to that book - it sounds like something I'd read.

Yeah phased arrays have probably been the rule for decades at that price-no-object level.

Even at the consumer level, there have been phased-array marine -sonars- (e.g. Interphase brand product line) for at least ten years for "only" 4-digit prices. Spatial resolution is of course tied to the number of elements but they do present more information that your typical 1-d "fish finder."

OldSchool··on How does a fighter jet lock onto and keep track of an enemy aircraft? (2013)
Hmmm, I was kind of hoping for an explanation of how the control system determines how to modify the highly directional antenna's orientation to continue to maximally "illuminate" the target once it's been selected from a general scan.

Can anyone describe the solution to this?

Example idea: Once selected for "lock," the antenna scans in small circles and migrates its central point toward the point on the scanned circle that provides the strongest return, allowing for variation due to noise sources.

OldSchool··on Colleges are full of it: Behind the three-decade scheme to raise tuition
It comes down to at least two things:

1. Easy (to acquire) debt drives demand

2. Education is still "Made in America" thus it cannot hide from the real devaluation of the dollar

OldSchool··on Curse Of The Gifted (2000)
I'm surprised nobody's mentioned this curse's endgame: getting a typical corporate job.

Everything about it is against your nature: fixed schedule, dictated product and process, micro management and arbitrary accountability compared to the creative freedom of your life when delivering academic performance on a timescale of weeks or months was your only responsibility. Worse still, it's not an "X year work program," it's designed to be endless.

Not that an entrepreneurial career is for everyone, but if you can be dumb enough to try and smart enough to make it work at a sustainable scale, it sure beats a guaranteed slow corporate death.

OldSchool··on How Silicon Valley CEOs conspired to drive down tech engineer wages
Steve Jobs said it well, "this means war." The engineering profession as a whole needs to play "war" like adults. This is going to cost money like anything. A permanent PR company that at least gets the engineering profession a louder voice than Marissa Mayer would be a start. A permanent lobbying budget to slowly but continually chip away at domestic and international threats to the buying power of your talent with changes in law is the other half of how grown ups play "war." No need to act like laborers and form a union or have strikes. Real change today happens via PR and lobbying. A well-funded and run professional organization formed with this as its sole agenda would do wonders for all of us.
OldSchool··on Cities and Ambition (2008)
One thing I don't see in the article or discussed here is that (at least I believe) a sign of reaching maturity is that you don't need to define yourself by where you live. While these places can be helpful in achieving your goals, ultimately wherever you go, there you are.
OldSchool··on Rails Consulting for Fun and Profit
If the Affordable Care Act providers deliver what they seem to promise, it's tremendously helpful to small-scale entrepreneurship. Pre-ACA, once you had a family with any health claim history it became increasingly difficult, expensive and invasive to obtain individual health insurance. In some states, maternity coverage was not offered in any usable form. In short, the system was heavily in favor of being a slave to any company large enough to have a group plan. Not only does the ACA makes it easy with its "no questions asked" approach, pricing is 30-50% less than the real cost of similar pre-ACA products. Also, if you have a slow business year, you can get a substantial premium refund via the tax credit, making insurance no longer a primary reason to "get a job."
OldSchool··on New Health Law Frustrates Many in Middle Class
From what I've seen, corporate plans are becoming more and more like what was once called major medical insurance.

So yes, coverage for anything below a small crisis is non-existent under these new plans, but it's about the same under the old plans. I'd rather bank the 50% monthly savings and know that my family can stay insured no matter what comes along.

As for the artist couple, they've got to be better off than having no insurance at all under the previous situation.

OldSchool··on New Health Law Frustrates Many in Middle Class
I've never found much to like about policies pitched by any of our leaders left or right, but ObamaCare surprisingly seems to be something that is positive.

It may not be much different for single people or those under 30, but if you have a family, keeping them in an acceptable PPO was running $1200-$1500/month (total corporate or individual) - and for individual, that's if you don't get rejected for something as ridiculous as someone having been treated for allergies.

Plugging in some numbers on healthcare.gov, I'm seeing comparable PPO's for $700/month and if you play with the numbers you can see that the tax credit drops the plan cost as income drops below 4x the poverty level, so for example a family making $50K/yr would only pay $200/mo for the same plan.

This seems like a step in the right direction in so many ways.

I think most negative publicity is coming from polarized sources who would reject anything, and their paid media outlets.

OldSchool··on What It's Like to Fail
Unless you're the rare tech entrepreneur getting a lifetime's fortune in a single acquisition event, or the equally rare successful serial entrepreneur, there will be ups and downs and you won't know the outcome until years later. The specifics of what you do today will inevitably become irrelevant even if it's the hottest technology of the moment. Save and continually adapt.
OldSchool··on The short, tormented life of computer genius Phil Katz (2000)
In contrast to the far overused sugary definition, Phil Katz really was a rock star programmer. He also died a rock star's tragic and pathetic death.

There is probably no line between self and business for a guy like PK. At that time you could build a significant program or even a game singlehandedly. Most likely he obsessively made his better ARC program for its own reward (you could use it for free) and he was surprised both by the commercial success and the subsequent legal attack. Very personal indeed, and if he wasn't already a completely tortured soul, that would be more than enough to take away any shred of sense he had made of the world. Give enough cash and free time to someone who has been cracked like that and he quite easily can end up dead from an existential crisis with no practical boundaries.

Considering this was some 25 years ago now, if he thought about intellectual property issues at all, the mindset at that time was very reasonable in that your source code and executable was considered copyrightable like a book - it didn't matter if it provided the same functionality as someone else's program as long as you wrote the code. Just consider the fate of the original spreadsheet for confirmation of this.

To summarize, before you take any stand against the tragedy that is the life of PK, consider that there is probably a huge concentration of people very much like the early Phil Katz right here on HN. The man simply needed help, and he didn't get it.
