I'm in a similar situation - been programming for 25 years (off and on) since I started in middle school on my own. But in school we had 'Algebra I' and 'Geometry I' and I never went beyond that. Struggled with quadratic equations and factoring, never heard anything about trigonometry (which I now realize starts in basic geometry), calculus, and never heard the words 'function' or 'intuition' in regards to maths in school. Tried to do the classic Andrew Ng course on data science and I was completely lost every step of the way because of new language and the fact that his class was nothing like the way I had been taught so long ago.
Accessing ppu (graphics chip of NES) is a bit convoluted but yea, probably easier than more sophisticated hardwares.

Ok, I have a use case for this. If you could figure out how to get it off the cloud and low power, it would be awesome to have one of these on the gates to my house, so when I drive up the plates are automatically recognized and the gates open to my car.
It's a bit tricky because part of the valuation is 'replacement value'. A problem with San Francisco is building now costs something like $600-1000 a sqft.
Agree. And if one is a well paid software engineer, one can definitely afford to pay a maths grad student for an hour week, preferably a bit more than whatever pittance the local univeristy pays them for being a tutor. You will progress far quicker and with fewer wrong turns. It is also far cheaper than enrolling at a university. A personal trainer for the brain.
Sometimes even the most minor tweaks can have massive unanticipated consequences.

Just as an example, even something as small as switching to a type of lawn grass that was lighter or darker to cover 1% of Earth’s surface, so that it reflected or absorbed just 1% more sunlight, would result in the Earth absorbing or reflecting away about 1/10,000th more light than now. It sounds small, but that is 20 terawatts of energy, which for comparison is 10 times humanity’s total power consumption and parallel to the rate of heat energy released by a powerful hurricane.
Not everyone is at a startup. I’m a bartender with a physics degree who’s learning more math in my spare time for fun, and to eventually switch to some sort of data science career if I tire of bartending.
Ahh okay. Sorry I made assumptions on what it did as it looks fairly similar. Have used mitmweb before but this looks to have nicer usability etc
I'd be curious how you built the step from regex to ElasticSearch. My guess would be an n-gram (3-gram) index in ElasticSearch and then translating the regexes to that, but just curious if you built that custom or used something off-the-shelf. Love the site!

> No, marketing as driver will cause massive feature creep.

Marketing is about exposing your product to your target customers. It's relatively orthogonal to product features.
you get better products. the store gets better sales.

this is already happening and it's already providing value.
No, you can own a TV without a license.

You must have a license to watch broadcast TV or use the BBC iPlayer (the online BBC-only streaming service). If you only use your TV(s) with a games console, to watch recorded content or streaming content over the Internet, you don't need to pay it. You are not required to provide access to an inspector from TV Licensing to confirm that your TV isn't hooked up to an aerial or satellite box, but it makes life easier if you do.

The license fee costs £154.50 a year, or £52 if you only have a black and white TV (lord knows how given we're now 100% digital), but the government pays it for you if you're over 75 years of age.

This produces an income of ~£3.5 billion a year, and broadly breaks down into 55% spent on TV broadcasting, 17% radio broadcasting, 10% for the BBC World Service and the rest of it goes on the website, various apps, collecting the fee itself and the transmitter network across the country used by all terrestrial broadcasters, not just the BBC. It also pays slabs of cash into the EBU who produce the Eurovision Song Contest, amongst other things...

This results in nine national TV channels, 10 UK-wide radio stations, six national (i.e. England, Wales, Scotland, NI only), and 40 local radio stations. The BBC website, iPlayer, apps in the App Stores, etc. are all paid for through this as well. If you're outside the UK you will see adverts as it can't subsidise access for non-UK citizens, but inside the UK all this content is 100% free of all advertising other than to cross-promote BBC content.

In recent months the Government have suggested that it's an unfair burden. There are two sides to this truth:

1. Most magistrate courts seem to spend a significant amount of their time dealing with non-payers, and there are people in prison for non-payment. IIRC, it's the most common crime committed by incarcerated women in the UK. For context, it's worth noting that the incarceration rate in the UK is about 1/5th of the USA's so the actual number is still quite low, but still...

2. Most people think scrapping it is a political move, because there are weird power dynamics between Downing Street, the execs in charge of BBC News and the rest of the BBC who seem to have problems with the News division and their friendliness with Downing Street and the PM in particular.

As a result, I think most people would prefer that the license was cheaper, the penalty for non-payment could not include prison and that we keep it.
Code Practice and Mentorship for Everyone
As some of you may know, I have been traveling the world as a digital nomad for more than two years. In the past two years, I have used Instagram, WhatsApp, iCloud photo albums, etc. to share my experiences with my friends and family. In fact, sharing pictures and videos of my travels by broadcasting across social media has become so easy that the process itself has become both addictive and mechanical - certainly not fulfilling, and more importantly - hollow and impersonal.

The value and meaning were lost for me.

This got my wheels turning. I want to share important updates with the people I care about. Social media is no longer built for connecting beyond likes and shares.

There has always been a special place in my heart for postcards, and social media updates just don't match the feeling of sending and receiving a postcard. They are a way of communicating that still holds value intrinsically - a physical reminder of connections I've made and the people I hold close to my heart.

That's why I still send postcards when I arrive at a destination. When I visit people, they show me the postcards they have received, and it opens up a conversation beyond what's on the card. We discuss life, our experiences, and our passions.

While I prefer postcards to social media, the biggest problem with postcards is the inability to share more than just a message. Postcards have the potential to be so much more than just a personal message - postcards should be able to share pictures, videos, and personal messages. But how?

With a sprinkle of magic, a touch of augmented reality, and a little help from friends - that's how!

Timelense is an app-based postcard design and communication platform, inspired by and built from a desire to share experiences in a personal way - to encourage meaningful sharing of 'status updates' with the people we love; a longing for a simple way to foster genuine connections beyond the pixels.

How it works:

1. Travel - and take some photos and videos while you're at it!

2. Use Timelense to create a postcard - customize it with pics and videos from your trip.

3. Once it's ready to send, we'll deliver your postcard for you.

4. When it's received, recipients can use the Lens within the app to activate and animate their postcard.

5. Voilà! The postcard will come to life with photos and videos.
Not who you're replying to, but I've answered this in detail higher up in this thread.
In theory with correct settings you should get all (or be told that the results are partial, e.g when shard is unavailable or timed out).

In practice there are bugs, which are notoriously difficult to find and reproduce when you go distributed. Jepsen is closest to that I know about.

I'm pretty sure Elasticsearch supports regex search, it's just that it's horrendously slow and can blow up the system.

They're required by law to give you execution at the market price or better, see https://www.sec.gov/fast-answers/answersbestexhtm.html

Because of this, it's legally forbidden for them to mess with your prices in such a way that you lose anything.

I think people see that these firms make money from selling order flow and as a result assume that they must be losing money somehow. That isn't the case. Some firms (e.g. HFT) are simply willing to pay a little extra for the counterparty to their trade to be a dumb joe instead of another HFT firm. This can lead to both you and the broker winning.
I'm studying for a Math BSc with the OU and I think their books are great. They are designed for 100% self-study and are polished over the years. The range of topics in level 1 math courses such as MST124 or MST125 is huge, while keeping the appropriate level of difficulty.

Instead of measuring "enhancements" vs "defects", just treat them all as one. Things that go into the product via demand usually has some backlog anyway ("Backlog item", "User story" etc on a higher level). What might be interesting is marking things as regressions or not regressions which might give some hint about which areas are too complex or too undertested.

The behavior of the stock market is basically the collective behavior of millions or billions of individual humans. Regardless of what complexity class that happens to fall into, it's just not possible to predict it with any accuracy. Even predicting in the most general terms the outcomes for individual companies is largely impossible; it's not hard to find evidence that the performance of individual brokers and funds is mostly random, with up years and down years and effectively no overall trends.

Good luck!
I've always had this love/hate relationship with the PI where I love the amazing SW the community it putting out for it and I hate the closed source Broadcom hardware/drivers and the rookie design mistakes the RPi foundation keeps making over time giving me the feeling they don't test their designs at all before launching them out to market.
Is there proof that something like this actually happens in countries with universal healthcare?

Is there proof it is actually worse than the current US system, where people with preexisting conditions or other risk factors are routinely denied coverage?

Otherwise, this is just plain FUD.
Real data is almost always dirty. But the filtering and replace transforms could help with that.

>I'm just not sure that your target market knows to look for a tool like this

Perhaps not. I am getting traffic for things such as "merge csv files" or "join excel sheets". But they mostly bounce without downloading the free trial. Even when I send them to a dedicated landing page. Most people really hate change.

>That works for csv, but with JSON, it's even harder.

Currently I am only exporting JSON (not importing). Importing JSON would involve potentially flattening a tree into a table, which is harder.

>- No cli options - No api?

Command line is high on the wish list.

Given that I am aiming mostly at non-programmers, I'm not sure an API would be useful. Note that there is a 'Javascript' transform, which adds a lot of flexibility if you are able to do some scripting.
this question makes no sense.

PR firms are so powerful now they can make any brand great again. See Microsoft. I guaranty there will be people that will want to answer this comment stating how they really are a good firm now. And cite great things they do. Yet I bet in 10 years, we will learn about some other horrible things they did. Again.

In rhetoric this is what's known as "inoculating the argument", or "inoculation theory". You take a reasonable criticism of what you've said and present a weakened version of what someone might respond with in order to suggest that means that response is invalid.

The thing is though, in this case, you've not really presented a solid argument. All you've said is "Microsoft might be doing terrible things!", which is potentially true, but it's a bad reason to ignore the obviously good things that we can see. What your argument boils down to is that once a company loses your trust they can never get it back regardless of what they do. In which case you're removing yourself from the conversation because you're only ever going to be negative.
Great idea for some products, infeasible for others. I recently needed a Firewire cable, on a day's notice, and after much searching I concluded there's no longer any store in Seattle which sells computer components in person, especially outside of normal business hours.

The closest I found was Fry's (Renton, 30min away), and they're doing their darndest to go out of business. A Firewire cable in one of the few items they have on their shelves. It's not name-brand, and if it didn't work, I'd be SOL.
>What about Spectre? It is an hardware exploit, thus there is only so much one can don in software to prevent it.

And there has been mitigations done in software in the Linux kernel (and the web browsers but that's userspace), so my question:

Plus for a microkernel, this can be a big performance issue..

I don't think it's investors feeling grouchy as much as Wall St. reporters who seem unable to write in anything other than garbage language. BH management do not concern themselves with short- or medium-term performance much; eyes fixed firmly on the long term. This is utterly foreign to most finance journos.

If you read Buffet's letter to investors, you'll see him explicitly saying that some years are bound to be less than wonderful, but that over the long run, envestment in BH will do well.
I have my doubts that the people who write these kinds of posts truly did everything they say.

>Who is your target audience (programmers, analysts, accountants)? What industries can benefit most from it?

I think it is probably a non-programmer business analyst, marketer or scientist with lots of Excel or CSV files to munge together. But experience with other products tells me that you often end up selling to different markets than the one you envisage.

iPlayer streams about 350 million shows a month. It accounts for a fair bit more than 15% of UK internet traffic and is more popular than Netflix within the UK.

I have worked with plenty production postgres instances that have much much higher loads. As in > 100 (on larger machines obviously). It's pretty easy to have workloads where the hot data set fits mostly into RAM - and if that's the case the read portion of that workload is usually bound by context switches and CPU processing time of the queries.

That's not my experience at all. A few years ago I would have been looking for the unknown chinese brands that could provide me with a gear that was "good enough". Now I will not even consider buying anything that is not from the top 5 brands for each thing. I have been burned too many time by products that were _almost_ as good, but not quite, and broke quickly. My branded gear is usually lasting forever (lenovo laptop, bose headset, roomba cleaner, instapot) as long as I buy on the medium/high-end end of the spectrum.

The thing is that as it is said over and over in this thread, you cannot trust reviews, and I would add that you cannot trust most of the smaller blogs/review websites because most would say anything about a product as long as they are paid.

If I buy the new Sony noise cancelling headsets, I know I will not get disappointed: it is a reputable brand, and it is the high-end of the range. This strategy is not perfect, far from it, and some brand are taking advantage of it. In that case, vote with your wallet. You can't really do that with no-name brands.
