I am aware of this and I agree that my example is a simplistic one. But it is what seems to be on the mind of most option traders.

> Your risk issue is shortselling an options contract. Not shortselling a stock, which would be the actual opposite of your buying example

Interesting article, some parts in the beginning is useless and detracts value from the interesting bits.

I think this is much less true now than it was 10 years ago.

On the positive side, capsule-based espresso machines do deliver consistent, good quality coffee at home, better than you would get with a consumer espresso machine using pre-ground coffee that you keep in a vat for a couple of weeks.

On the negative side, I am often disappointed by the quality of espresso in (Italian) coffee shops. It used to be that the quality of coffee was paramount for a coffee shop, and a good barista either learned how to get good coffee quickly or went home; now it seems this is perceived as a much less important part of the trade, and you regularly get restaurant-quality (as in very mediocre) coffee in coffee shops. Not sure if Nespresso played a role in this too, as less people are walking to a shop to get their coffee.
They've listed some uses for it — animated videos, e-learning (the likes of Khan Academy). While I doubt that animation would shift to vector video any time soon, it indeed would help e-learning a lot, speaking from the side of the content distributors (less size). The only benefit for end users might be faster streaming, but yeah, I agree that the average user can't be bothered about it.

You can take the Nespresso machine out of my dead cold hands. It improved my life significantly: no more ground coffee spilling all over, no more cleaning and drying the mocha every day, no more having to worry about the right amount of coffee or water, whether I’m drinking too much, why I didn’t get crema... It’s slightly more expensive than simple mocha but still dramatically cheaper than anything you find in coffee shops (outside Italy at least), and worth the peace of mind. Now they have a saas-like offering so I don’t even have to worry about how much I spend, it’s automatically budgeted and withdrawn and I just make an order every few months.

The only criticism I have is that most of their varieties are not 100% Arabica, and often it’s hard to find out if their “special editions” are. Robusta is bad for your blood pressure, but sadly it’s cheaper so it ends up in most mixes. This said, I think their last batch was almost entirely Arabica flavours so maybe they are improving. If you care, I’ve done a bit of analysis two years ago that covers all classic varieties (I really should update it) at http://blog.pythonaro.com/2018/04/nespresso-blends-comprehen...

(Oh, and fuck Vertuo. I’m happy to read it was an attempt at courting Americans, because from here it looked like just a simple money grab to raise the cost of capsules and maintain exclusivity on the format. No thanks.)

OKRs are just a tool, but having been the founder of many startups, comes a moment when you need a tool to align your team towards a clear goal.

I understand most of the comments but as you grow your startup will come a time when it becomes useful when you have 70+ and even more thousands of employees. The bigger the company the harder it is to manage, google famously hated management and ended up with OKRs. My understanding from a couple of ex-googlers is that now most people are just gaming the system and aiming at a 0.7 score so I'm not sure if they are still as useful as they were at google.

OKRs / KPI etc are not magic, at the end of the day the article is right, the team is what matters, how teams align and communicate with each other is what OKRs can help with (I find them better than the old top down KPIs personally) I was asked by a startup to explain OKRs and I kept getting the CEO to ask me questions related to them not making sense (e.g some teams argued that goal X did not make sense to them etc...) For me this was not an issue with the OKRs per se, but OKRs helped to show very clearly that the organization was not well structured for the general goals, so worst case if OKRs don't work you should be able to tweak things and measure the impact (that's the all idea : measuring to improve)

Is Google success because it's a well run company in the first place? It's obviously not terrible (I'd personally love to work there) but life is a lot easier when you have the biggest cash cow ever plus a few smaller ones.

In general I'm skeptical whenever anyone wants to copy Google as their advantages and disadvantages are so far removed from a typical company and always were. I don't think they're a particularly good company to model for most companies.
I've been thinking about a "meta cloud" stack - essentially something with the convenient interfaces of various common SAS but then backed up by a user configurable transport.

So you could "migrate" existing apps to say, use some machine at a colo instead of a variety of s3 services without much effort and thus unshackle yourself from a vendor.

Maybe you are making gobs of money and don't care, but a lot of people aren't and saving, say, a few hundred a year sounds very tempting. Not every competent person is rich

I think your technology would be useful for restoring old animated videos. Plus it would be useful for The catchy intro animations used on startups to demonstrate their technology.

Also would be nice to use when you have bad internet connection speed to watch e-learning material animations.

For e-learning you may need a hybrid M3u like Playlist approach with video for the presenter and vector graphics for the screen casts.

Manga videos would probably also compress well.

Children animated videos.

What if you would reduce the color space vectorize of ordinary video to for example 8 colors and smooth out the noise to make large flat surfaces could you compress it with vectors?

Yes, I do use IBKR, which is one the "real" brokerage platforms.

Your portrayal of RobinHood is a caricature.

Crashes? It happened a few times. I'm not an active trader, so I don't use IBKR all the time, but even in my light usage when I couldn't log in because their security-theater activation code never arrives.

Often IBKR can't show the value of my portfolio because, apparently, they can't load the data.

The whole web app is slow, switching between different parts is slow.

They don't even bother to send you an e-mail immediately after fulfilling the order.

The way RobinHood show option pricing makes way more sense than IBKR's view.

"Terrible fills on order" - you're just making stuff up. Care to show evidence that some other brokerage can fill your order faster or at better price than RobinHood.

>Oh, and the rejection. The non stop rejection. Every single day, minute, hour. Investors, customers, employees, potential employees. It's not personal, but it sure feels personal. Even when things are going great, there's tons of little micro-rejections, non-stop. I wish someone told me that.

THIS! You feel like your back is always against the wall and you have to defend every product decision. You are right it's not personal and probably good the feedback(most of the time...) but you ja it's hard getting rejected 24/7.
And even criticism can later be seen as "rejection" :/ Maybe it's best to view these things not in isolation but on a timeline.. Sure many of the things I produce today, might still suck, but I think it sucks less than my products from 8 years ago. Growth is definitely there.
> To expand on this, the answer isn't buy a CDN solution. The answer is make CDN solutions so easy to implement that anyone can ...

... update their CNAMEs to point at a different company's CDN or a different video serving platform, and wait for the DNS to propagate

To me at least, the risk of a CDN or a video hosting service going bad or pulling your content is mostly the same risk as "colos around the world" going bad or pulling your content. Possibly a lower risk for most people - the chance of Cloudfront/Cloudflare/Akamai or AWS/Azure/GCE going broke or shutting you down is quite a lot lower than the risk of other smaller colo providers and your own hardware going dark. There's probably a smaller gap between smaller CDNs and cloud compute providers compared to rolling your own - but for most use cases I'd guess having a "cloud agnostic' design and ability to switch compute and CDN resources quickly and easily is a lower effort and more reliable way to reduce existential risk to your business.

I'm sure there are businesses who's risk estimates don't match mine - Darknet Markets for sure, probably "adult content" as well (given the observed puritanical zeal some of that industry gets deplatformed with). But for most clients and projects I've worked on in the 15-ish years since "Cloud services" became mainstream, owning hardware and leasing colo space would have been a totally misplaced cost/risk optimisation.(And I say that as someone wo used to do 2 or 3 trips a year from Sydney to colo facilities in the US and the UK with my luggage filled up with pre-loaded harddrives and toolkits to screw them into servers we owned on both US coasts and in London. I kinda miss the travel a bit, but I _totally_ prefer being able to get my phone out and provision new cloud "hardware" instead of hoping i had enough hot spare capacity somewhere, and ordering new hardware and plane tickets to fix disasters...)

I have a T100 with auto-off firmware. I don't have to put it on a stand, literally anywhere on my desk will do. Once I pick it up it'll be at temp before the tip touches the PCB in almost all cases.

The great thing about doing it in software is that I can change the timeouts and the idle temperature if I wanted. For most soldering my idle is 130°C so it can go quickly to target but when I'm experimenting I leave it at 80°C to reduce burn risks.

GPUs happen to be very good at drawing shapes. So there's probably a lot of room for improvement, probably even enough that these kinds of videos could be faster than decoding "normal" video (for which modern CPUs and GPUs have dedicated silicon).

This doesn't mean that I'm not entirely skeptical of this, especially because this probably will fail spectacularly for animation that isn't just vector graphics, which is most animation.
If you want to optimize a data structure for binary search, it sounds like it might be best to reorder the data itself in memory to make caching more effective.

For example the first access in a binary search will be the middle element, followed by the lower quartile or upper quartile. If you store all of those together in memory, a single cache line fetch can serve all those requests.
Mea culpa, I had the <1 numbers of flu in my head as the <10 number- I shouldn't have said "as badly". However, those charts aren't great- as someone else noted comparing estimated flu numbers with confirmed COVID cases is problematic. In my local region, a randomized serology study suggested that we have at least 3x as many infections as confirmed cases, and a raw extrapolation of deaths to IFR rates suggests its even higher.

It's best to say "the fatality rate is near the same order as the flu for school age children"

If you want to experiment now, I can recommend the TS100 or TS80. The TS100 requires a beefy power brick but it's one of the nicest all-rounder irons one can have for under 100$.

The TS80 isn't as beefy in power terms but runs of USB so you can power it from a standard phone battery bank or USB-C charger.

IMO for any hobbyist a TS100 is probably the best bang for the buck unless you go for rather expensive soldering stations.

I am surprised about your comment. What do you find hard to believe? I am from (western) Germany, and I find it hard to believe, that there are class rooms without windows. Except for one or two special purpose rooms, in my school time, I have never ever seen a class room, which didn't have windows on one long side. The other long side would be towards the hallway. The rooms almost never needed artificial lighting (unless in the first hour in the Winter or really bad weather) and plenty of fresh air when opening the window. Daylight and fresh air are the best ways to keep the pupils awake.

A digital scale is game changing for baking and (to a lesser extent) cooking. I dragged my heels for years on the purchase and I absolutely regret not having bought one years ago.

Just think about how annoying measuring a cup of peanut butter is, scraping it out of the measuring cup, washing the cup.. vs just adding spoonfuls of peanut butter to a mixing bowl.

You can still bake just fine with measuring spoons and cups but you’ll be more consistent and better with the scale.

They are required for experiments. I like to add a small amount of baking soda into my banana bread for a nicer crust but if you add too much, think 0.X grams too much, then the banana bread could begin to have a vaguely pretzel-like taste.
