chris_dcosta··on Class switch towards non-inflammatory IgG4 antibodies after vaccination
I found this paper to be less than objective in its introduction and commentary. Statements were made that had nothing to do with the research itself, and therefore did not relate to supporting data and were superfluous. I really don’t like reading papers like this because my initial reaction is always “why do they say this, and who reviewed the paper that allowed them to pass?”
chris_dcosta··on How much gold has been found in the world?
I learnt (40 years ago) that all the gold in the world made into a cube would fit under the Eiffel Tower.
chris_dcosta··on Insurrection as a Service
As technologists we have always had a responsibility beyond just doing the job. We don’t all see it that way I know, but for example we choose to use encryption for reasons that should not even be up for discussion. We have platforms and services that can be used to provide some direction to society, when we as fellow human beings see it going awry. Sure there are those who will overstep the mark, but you cannot hide anymore and this is the reality that any would be fascist has to face.
chris_dcosta··on Ask HN: Am I using this site correctly?
No, I can tell you from experience, you'll know when your postings aren't suitable. They end up on page 20+ in no time at all.

It's definitely not the volume of posts that puts them there.

chris_dcosta··on Is cryopreservation still relevant if we can build digital brain models?
Technically you are not the same person as the 5 year old you. Every cell has been replaced.

It would only be a facsimile of you at a specific moment in time... which would make each facsimile on parallel paths... scary

chris_dcosta··on Ask HN: How would the world be 20 years from now with absolute free market?
"Can a free market naturally produce a safety net?" When Margaret Thatcher was asked before she succumbed to dementia if she would do anything differently, she replied that she had believed, that making people rich would mean that they would help the poor, but now she realised that they don't.
chris_dcosta··on Ask HN: why do we accept that governments may have secrets from citizens?
Thanks for the downvote. The inverted commas mean that I don't actually agree with this, just as the original poster probably does not count themselves in the "we".
chris_dcosta··on Ask HN: How do you encrypt your email?
BitMessage
chris_dcosta··on Ask HN: why do we accept that governments may have secrets from citizens?
Because "you can't fight the system."
chris_dcosta··on The NSA, CALEA, and the hardware backdoors built into routers (required by law)
I guess any customer using US Equipment in any part of the world is also accessible, even without a local law supporting it?

Interestingly I managed to discover a Huawei trojan that installed itself without me granting permission via a hotel router. It wasn't particularly well built back in the day which made it easy-ish to identify.

Makes me wonder where China is going with all the deals Huawei is making with Govts across the world too.

chris_dcosta··on Ask HN: Do you always FULLY understand the code you are working with?
I think the important thing is not to understand all the code, but to know where you are and why you are there.
chris_dcosta··on Ask HN: Do you always FULLY understand the code you are working with?
This is so true you cannot believe how hard I laughed.

I have a particular coding style (own-prettifying), and so I can tell if I authored the code or if someone else has. I can also tell if mine's been edited by someone else too.

chris_dcosta··on Ask HN: Educating a child who is severely behind
Tread carefully. You are in a relationship with someone who really is the new parent, and whilst you may act like a father figure, and have ambitions, don't get that confused with who's child it is. I only say this, because the last thing you need is resentment to build up because you might be able to do something that the real parent was not able to do.

I'm sure you have talked this all over with the parent, and like you say there were mitigating circumstances, but it is the other person who has the right to the decision-making. Just keep that in mind that's all.

chris_dcosta··on Ask HN: Banned from both Google AdWords and Facebook Ads - What to do?
Of course it depends rather a lot on how deep your pockets are and what sort of return you were getting on your Fb and Google ads, but these are not the only sources for advertisers. There are plenty of other types of advertising, affiliate companies, remarketing and the like.
chris_dcosta··on Awesome flash websites from the 90s
one of these games maxed my CPU. Can't imagine what it would have been like back in the day.
chris_dcosta··on Ask HN: How do I "prove" my app doesn't infringe on existing IP?
You obviously cannot prove a negative to start with, but in the interests of being non-confrontational, you should just come out and ask what they are looking for in this proof.

I was once asked to prove that future litigation had already been dealt with (my reaction: WTF???) before somebody bought something from me. It turns out they were looking for a specific certification, which was easy enough to obtain.

The point being, they had asked the question in such an odd way, that it just confused rather than communicated.

Just ask them what they expect to receive from you in the way of proof, or that would be acceptable proof, and then go about getting it.

chris_dcosta··on Ask HN: Have you ever cold called someone?
If you are asking about how to get over the fear of cold calling from someone who is naturally shy, take it from me, the first few calls will be awkward and you'll trip over your (probably prepared) speech. Don't worry about that, make sure that the first few calls are the least important ones. Use them as practice runs.

Try also to go via a switchboard, or a reception desk. This way you can 1) practice on the receptionist 2) get a feel on how responsive the company is to this approach 3) get some names to contact directly

As someone mentioned here it is a numbers game, and believe me the more you do the easier it gets. You build up resilience to the responses, and after a while you find an approach that works for you.

Another one I tried was pretending to be someone else, for example a student doing research, (ahem social engineering student haha) and as I got into the role, it became dead easy to speak freely....

chris_dcosta··on How do I fire my recruitment agent?
I suspect you are right about the desperation thing, on the ground the client is under some pressure.

But look at it this way, if the client was asking for a small reduction in the rate the agent would be on the phone right away asking me to take a cut. They would also be getting a cut as their %age is based on my rate.

To be fair and honest, if the client is offering more to get you - for whatever reason - then that must filter down.

That just didn't happen here. The client therefore has also been mislead because they think that I am being paid appropriately. Instead the agent is profiteering.

chris_dcosta··on How do I fire my recruitment agent?
This is not like the sports industry is today. It is however like the sports industry used to be.

In the past sports agents worked both for the team and the player. This lead to exactly this situation, players and clubs getting shafted by the agents.

It changed when some smart person decided that the clubs and the players should have their own agents, and that if a club wanted a player because of their talent - which is the main reason - they had to engage their own agent 1) to attract the player 2) negotiate a price with the play's agent. The pplayer paid their agent 10%, and it was their job to defend the interests of the players against the interest of the club.

Hence today we have players paid huge amounts based on their talent.

chris_dcosta··on How do I fire my recruitment agent?
Firstly, I know my true market value, and have done for years - I always find a way to find out ;) and I haven't just got off the boat.

I also know what I can get away with making in this market, so what I'm making is not the issue per se, although this is below my normal rate, and I agreed to this on the grounds that were presented to me - which turned out to be completely false.

I work with many recruiters, not just this one. This one happened to have a job available at the time I was available...

Lastly, they point blank refused to negotiate, at all. Hence the need to fire them.

chris_dcosta··on The rise of alternative cryptocurrencies
"But what is the real value in these?"

Perhaps you should think about the real value of money.

Disclosure: my post.

chris_dcosta··on Ask HN: Why is my submission getting deleted?
I've only ever submitted one of my own posts. It got killed instantly. I had no track record of doing this, but I guess russel is right. The moderators don't like you doing it.

EDIT : I checked, you use a pseudonym I don't suppose it identifies you as the writer of the posts.

chris_dcosta··on Ask HN: Accepting Bitcoin for freelance work
I work with multiple currencies in the real world. However the earnings are made, they are always accounted for in the currency of the company.

If you publicly acknowledge that you are accepting bitcoin as payment, beware that you will have to account for it's value on the day of the transaction. This means that if a person buys a pair of shoes at $50 and you hadn't adjusted your own exchange rate in line with the market for that date, you could end up recording more $ or less $ for that sale, and you pay tax a % of your profit on that sale.

A freelancer however could, in theory, conduct their business entirely out of the public gaze, but that would also entail your customer playing the game. If at least one half of the transaction's address is known, then the other can be found out in the blockchain. It won't identify you specifically in the transaction, but your customer may be forced to disclose who they were paying.

chris_dcosta··on Ask HN: I find many "no men", what are "yes men" like?
Traditionally a "Yes Man" was a subordinate who did whatever his boss (it was always a man) asked.

Ask any singer or actor, hearing "You are great" all the time means you cannot trust anyone's judgement. If someone says "No" or "I don't like it", you can always follow up with the question "Please can you tell me why?"

chris_dcosta··on Ask HN: How big is Big Data?
In my experience, and I have worked in this field since 2001, "Big Data" is the the answer to the problem of poorly implemented reporting models. The excuse for bad performance has always been "the size of the dataset" not ultimately the real culprit: lack of technical knowledge on how to build an appropriate and performant model. Size of the data set is almost irrelevant, when it's done right, but when it's done wrong, even a small ( 100 000 records ) dataset can be sold as "the problem".

Business people love to chase a holy grail, this being yet another one.

chris_dcosta··on Ask HN: What happens to programmers after 40?
What happens to the programmers who are closer to 40, but aren't managers? They have a choice: a) continue earning a living doing what they do with ever-diminishing returns, regular holidays, time with the kids, or b) go it alone, and risk a hell of a lot more than the young. I read somewhere that YC tends to steer away from engaging with generally older people who's risks/dependencies are obviously an issue.

Would you want to hire someone older than yourself? Absolutely. But only for the job that suits both me and them. I may want someone who really has the experience to do a specific task with authority, and that is more often than not a greybeard, or enthusiastic experienced (40+) peer.

chris_dcosta··on Ask HN: Why haven't we built a decentralized exchange for bitcoins?
I agree with this - I think it's the fact that MtGox is the main exchange that's wrong. There should be multiple exchanges with proper backing.
chris_dcosta··on Ask HN: Why would a government have created bitcoin?
Isn't it amazing how many commentors actually know nothing about the mechanisms of the currency, preferring to comment from a position of ignorance in tabloid headline statements.

I find it very strange coming from a community of so-called "hackers" that this should happen, considering a) the interesting and complex technical mechanisms involved, and b) the "mysterious" circumstances of it's coming about. Who wouldn't want to get their hands dirty with it - at least out of curiosity?

In fact, it's what I find more and more irritating about this community,

Apologies @pg - just had to let off steam.

chris_dcosta··on Ask HN: is it possible to make high quality movie really low cost?
A well shot, well edited film can be let down by a poor stroy or a poor script. These are variables you have to get right so all the players have to be A players who get on very well together. good luck!
chris_dcosta··on Ask HN: Why would a government have created bitcoin?
I would have thought that if this was a government backed project it would include the ability "to know" - whether that be the persone, the amount or the "where" af transactions.

It would be pretty dumb not to include that aspect, but as far as I know, these are exactly the things bitcoin prevents.

There would be very few people with peer-to-peer networking skils the programming knowledge to put that together and thhe mathematical knowledge to create the algorithm and the economics knowledge to understand how to control inflation. But there are still weaknesses in the process.
