cdf··on Why Twitter didn’t go down: From a real Twitter SRE
Getting it to about 90% working in a single country or just the general western sphere, probably 100 will suffice.

Making it globally available and legally compliant, that's where the next few thousand folks come in.

cdf··on Why do SaaS companies need sales?
I was a sales engineer and I can assure you if your product is sufficiently innovative, nobody will have a budget for it, so this is an expected objection and every sales person would be trained to address it and they either were not paying attention during training or failed to qualify the lead, eg trying to sell Oracle DB to Larry and Sergey while they were still in a garage... of course they have no budget... not yet.
cdf··on Electric vehicles are way more energy-efficient than internal combustion
Or in case of Singapore, your heat wave is our most days in 80% humidity. And on the days it isnt hot, it's probably pouring rain... you know 10 seconds of it is indistinguishable from jumping into a swimming pool rain.
cdf··on Political Chips
I suppose the business courses you took are tech startup oriented. For tech companies until recently, the business is valued at roughly 10x revenue, so revenue is the all important metric. Profit is not important. This is why the barely profitable Salesforce and the non profit enterprise named Uber is worth so much in the stock market.

For traditional businesses, the metrics are profit and in particular profit margin (profit/revenue), so more revenue at same profit is bad. And other metrics like ROCE (Return on Capital Employed) and FCF (Free Cash Flow)... which incentivise lots of debt if you can borrow cheap but discourage capital investment. This is obviously antithesis of tech startups.

cdf··on Ask HN: Working in tech for climate?
Check out https://www.infogrid.io/careers , a company focused on improving building health and energy use through smart sensors. The company HQ is in London but moving to the US soon. Most technical roles are remote and still hiring.
cdf··on Tell HN: Salesforce has globally revoked Slack's holiday shutdown benefit
Not a current Salesforce employee and never worked for Slack, but from my POV when I was there, I can tell you Salesforce is effectively in the same state during this period every year, so I dont know what Slack employees will be missing out on.
cdf··on Do breastfed children have higher IQs? The answer is annoyingly hard to uncover
Dear prospective parents, esp first time parents, hoping to be perfect parents, I just want to tell you, after 4 kids, just do what works for you.

Your sanity has a bigger influence on the well being of your child than any single factor like religiously breastfeeding.

Breastfeeding is incredibly convenient when the mom is not working, and cost efficient. But if it becomes impossibly inconvenient or costly, eg while mom is working, dont beat yourself up if you have to resort to formula to bridge the gaps.

Also, baby formula marketing would lead you to believe that formula with omega3 will make your babies smarter too. That's probably the lie you should disbelieve in.

Raising a confident well adjusted child is more important to me than high IQ, and there is no objective way to measure that.

cdf··on Theranos former president found guilty on all fraud counts
Balwani wasnt just any employee. He was a significant debtor(investor?) to the company and could blackmail Holmes for her role in the fraud. Not saying Holmes is innocent or powerless, but it is not entirely fair to suggest she can fire him any time as he does have significant power over her.
cdf··on Actuarial Life Table
To be fair, if you are reading this or wrote this, you are far from a "typical" male in this study. The typical includes a lot of low income and/or blue collar workers who cannot or will not take good care of their health and are engaged in high risk activities at work and after work. In all likelihood, the typical HackerNews user alarmed by a subject like "Actuarial Life Table" will have much better odds at living a long life... if only because you are paid tech wages.
cdf··on Changing jobs during the Great Resignation
Until the recent two years, no referral means no response whatsoever, for me anyway... referral usually guarantees I will hear back, even if it is rejection, all else equal, including the exact same resume of mine.

EDIT: Forgot to mention, I work for a bigg-ish Tech, and the bulk of the new hires are referrals. Very very few candidates get hired without referral. The referral fee is so high, the hiring manager is usually inundated with candidates the moment a role is available. Very seldom do we need to seriously consider non-referred candidates.

cdf··on Why Do So Many Humans Need Glasses?
Yeah, I was diagnosed at 6, had my first sustained computer interaction at 9, had my first computer at 21, first cellphone at 25. (I'm old, but I also live in the myopia capital of the world)
cdf··on On SGQR, Singapore's unified QR code payment system
i'm from Singapore, what QR code transaction are you talking about? Never heard of it. Are you confusing us with China/WeChat?
cdf··on Peter Thiel sells most of remaining Facebook stake
Well said. For years now, I hear people say Facebook is not useful for "me" and I dont even disagree. But how typical are the "me"s among the billions of facebook users?

Furthermore, in many third world countries, the only internet they know and will ever see is facebook properties via internet.org.

I see the facebook logo on almost all retailers in my patch of the world. Retailers no longer advertise their websites or phone numbers. See us on facebook, they all say. This doesnt just happen without a lot of people brilliantly working hard and smart.

cdf··on 110M-year-old dinosaur discovered with skin and soft tissue
They both do digging and restoring, but only paleontologists study dinosaurs.
cdf··on Why Do So Many Zippers Say YKK? (2012)
You will stay hired if you buy AWS
cdf··on Intel made a huge mistake 10 years ago
Itanium was a trojan horse to get their rivals to give up on MIPS/Alpha/UltraSparc development. As soon as those CPUs lost all traction, Intel dumped Itanium as well. Intel was never serious about the Itanium. Considering how performance sensitive it ought to be, Intel chose to build Itaniums on older manufacturing processes. The fact that Itanium performance was hopeless should not have been a surprise.
cdf··on Where are you in your company's layoff list?
This will not be true if a long service worker accumulated a huge seniority based increments. Even past high performers who has taken their foot off the pedal would be in this group.
cdf··on LinkedIn has lost its vision
You should always be aware of industry trends to stay employable, including learning what skills recruiters are looking for. You are always one management change away from a reshuffle.
cdf··on The Second Smartphone Revolution
I think it is not right to map ncsa mosaic to the iPhone. Mosaic will more correctly map to the earlier smart phones like the Treos, window CE and symbians, which were in existence in 2003
cdf··on Undersea Cable System Cuts in Singapore
I'm in Singapore and this is not reported at all. Likely affects only Telkom Malaysia users only - one Malaysian telco lost their link to Singapore rather than Singapore losing link to the world as implied by the headline.
cdf··on How to Deploy All Day yet Deploy Nothing
When your dev teams are strewn all over the world and the lowest common manager with the people managing the OS is the CTO 6 layers up, you will find making things "just work" get exponentially more difficult and all sorts of workarounds and safeguards have to be put in to ensure small changes introduced by other teams do not screw up your portion of the app and vice versa, eg not letting the OS team control the JVM for fear security and performance decisions by the OS team will cause unexpected deployment problems... which will lead to performance and security problems that need to be worked on without OS team involvement...

Of course this is a slippery slope and often devs not familiar with RPM eg end up reinventing the wheel as each deployment failure breeds distrust between teams and more workarounds and safeguards get introduced.

cdf··on Let Twitter Be Twitter
You must think whatsapp acquisition is insane and fb ran by amateurs. The fact is Twitter is of great value to the likes of Google and fb, beyond simplistic pe ratios. In fact, pe is a very poor valuation tool for tech companies.
cdf··on The Buddhist Priest Who Became a Billionaire Snubbing Investors
I work for a best place to work company and hr really go all out to address any concern that may hurt the survey. That said, best place to work doesn't mean your job is automatically awesome.
cdf··on A Decade at Google
Where I worked, official hours are 8.30 to 6. In Asia of course.
cdf··on A customer explains how Oracle tried to strong-arm it into a cloud sale
That's not true. Salesforce is still on oracle db
cdf··on The media in Singapore: Zip It
You may want to read the link you cited. Also, Little India is not impoverished. It just looks so to a casual tourist. The fact is rent in Singapore is substantially driven by their accessibility to Little India.
cdf··on Why I’ll Never Return to Singapore
I dont like the Gardens, but it is not correct to say it is wasted. Precisely because it is reclaimed, it needs another decade or so for the soil to settle before we can build skyscrapers on it.

Trust me when I say it, real estate speculation is the primary path to wealth in Singapore, and the biggest, most well oiled speculator in Singapore is the government.

cdf··on Andreessen Horowitz Sells a Third of its Facebook Shares
So what if you know your balance sheet, income statement, FCF, capex, when you are analysing Enron or Lehman Brothers?

If you are so sure Facebook is overvalued, how big is your short position? Guaranteed win right?

Can you guarantee Microsoft won't swoop in to buy Facebook at 5x over "fair value"?

I think we have reached the point where is conventional wisdom that "professional" fund managers struggle to outperform index funds, so you can mock the financially illiterate, but I hope your investment returns regularly outdo monkeys throwing a dart.

cdf··on Children aren't born smart. They're made smart by conversation
Interesting tidbit: The Chinese phrase for smart, "聪明" quite literally means "clear hearing".
cdf··on Lessons from a year's worth of hiring data
As a person who is not totally secure with my command of English, I assure you I check for typos twice as hard for my job applications, including agonising over the choice of US or UK spellings when applying to US MNCs while living in a UK spelling locale.
