dbuxton··on LG G Watch R
Not quite on topic but my favourite is the watch face image for 10 Greek St (a great restaurant in London's Soho)[0]

It's reminding of a supper reservation but as many (I'm sure including the designers!) know, 10 Greek St doesn't take reservations for supper[1]

Tiny thing but suggests that whoever did the creative here had a sense of humour.

dbuxton··on Ask HN: Who is hiring? (October 2014)
Arachnys - London, UK - https://www.arachnys.com (Full time, permanent)

We're building the next generation of international business research tools - lots of data, heaps of automation, plenty of fun. At the moment we're looking for mid-career engineers but we're just about to post some ads for data specialists and front-end devs. We would love to speak to you whether you specialise in Golang, Django, Erlang or AngularJS.

Our clients are some of the biggest companies in the world, we're profitable but still early-stage enough that you'll have a significant impact on what we do (12 FTE). We work out of a beautiful space near Angel tube.

We want everyone on-site but will consider relocating exceptional candidates, including those from outside the EU.

https://www.arachnys.com/jobs or email founders@arachnys.com with your github profile/some code samples.

dbuxton··on Ask HN: MTurk is no longer available to non-US companies. How are you coping?
Unfortunately the payments sign up also requires proof of a US billing address.

It is easily possible to get an EIN however as a non-US company with no US presence; you have to call a nice IRS person in Indiana if memory serves.

LONDON, UK - Arachnys https://www.arachnys.com - Devops

We make sophisticated, multilingual search software for enterprises that need to scan thousands of data sources for information on customers and suppliers.

That means lots of data, handled by a small tech team which we're looking to scale as we ramp up the business. We're hiring Devops and full stack engineers at the moment. Remote is a possibility for exceptional candidates but we prefer at least part-time in London. https://www.arachnys.com/jobs/

We work in Python mainly but we're particularly interested in Go hackers at the moment.

Email us founders@arachnys.com with your github profile or resume if you're interested.

dbuxton··on The world's hardest CAPTCHA
My personal favourite is this one: http://random.irb.hr/signup.php

Although Wolfram Alpha can actually solve these pretty easily.

Arachnys - Engineering and DevOps - London, UK

We make a search platform for companies carrying out due diligence on their counterparties in emerging and developing markets. Our SaaS platform is used by some of the world's biggest and most prestigious banks and consulting firms to help them manage their counterparty risk. We have just hit breakeven, with strong growth, and are looking to invest to grow our engineering capability.

Our stack is a huge range of fun open-source technologies, including Hadoop, ElasticSearch, PhantomJS and Django. We mainly write in Python but are starting to use other languages, especially go, for key services.

We're looking for engineers and devops types to join our growing London-based team. Competitive salary, flexible working, usual startup stuff available.

Please email founders@arachnys.com if you're interested, no need for a CV if you can show us an impressive GitHub (or equivalent) profile.

dbuxton··on Auto-expiring TODO notes in Ruby
Fantastic idea and what I thought when I saw this post; I'm slightly surprised that nobody has produced a git one-liner to achieve this yet!
dbuxton··on Ask HN: Who is hiring? (May 2014)
Arachnys, London - https://www.arachnys.com/jobs/

Startup building the next generation of intelligence gathering software for emerging markets.

We're hiring:

* Devops engineer * Full stack developer

Both in the £30-60k range. See the jobs page for full spec.

We have fun challenges: on the data side, we have 100TB+ of data in Hadoop that is growing every day, a 10TB+ ElasticSearch cluster and some pretty fun custom crawling tech written in Python and deployed via Ansible. On the other, we have a frontend app that we want to turn into the best investigative experience on the market.

Team is small - 13 at last count - and we're at break even with some huge customers already on board. You'll be coming into an environment where every commit counts, where we automate everything we can, and where we try to use the best tools for the job.

Email founders@arachnys.com if you're interested and think you've got the skills. No remote and no visa sponsorship.

dbuxton··on On Riemann (network monitoring app and dashboard)
It's not clear from your comment exactly what you're looking to do, but difficulty of configuration was more or less why we built Cabot (https://github.com/arachnys/cabot) internally for monitoring our infrastructure. However very possibly you're trying to do something more complicated.
dbuxton··on Show HN: Self-hosted, open-source infrastructure monitoring and alerting
Glad to hear it, thanks for the positive feedback!
dbuxton··on Show HN: Self-hosted, open-source infrastructure monitoring and alerting
This sort of service-oriented monitoring is very close to the pain point that caused us to create Cabot.

In our case, it was more that there were multiple things we could monitor for that potentially indicated a problem with a service but it was hard, using Nagios or whatever, to tie those individual indicators back to a single service going haywire at 3am, especially if all 50 of them blow up at once.

We don't have the precise problem that you describe though - for us the ability to monitor the number of data series in a graphite collection (so that if a server disappears we can notify, and then if another drops off we can alert) is sufficient. Cabot can use this and the ability to tolerate a number of failures to give behaviour very close to what you talk about. However I don't know if Cabot would support the kinds of checks that you're carrying out out-of-the-box, you'd probably have to extend.

dbuxton··on Show HN: Self-hosted, open-source infrastructure monitoring and alerting
Don't see why not, but all the upstart stuff is platform-specific.

I'd suggest you spin up a clean Ubuntu instance in Virtualbox and just run the fab deploy script against that locally... It won't be fast, it won't be pretty, but I'm pretty sure it will work.

dbuxton··on Show HN: Self-hosted, open-source infrastructure monitoring and alerting
Primary author here. Please add an issue at https://github.com/arachnys/cabot/issues/new and we'll look into adding. (Essentially that's all Hipchat is).
dbuxton··on Show HN: Self-hosted, open-source infrastructure monitoring and alerting
I think the thing for us was that we couldn't understand how to make Nagios see the world in terms of services (which are sometimes a set of machines running on physically or virtualised infrastructure, but sometimes individual servers on shared hosts). I'm sure it can be done, I just couldn't wrap my head around it.

Also it was surprisingly easy and fun to write. Probably has taken longer than learning Nagios but I don't think I would have spent Christmas hacking away at that task...

dbuxton··on Ask HN: How do you manage your sales leads?
We like Pipedrive's overall structure (in particular for the way it looks a bit like a Trello board) a lot for the types of sales we do (multi $k/month deals).

The interface is kind of slow and laggy which for something that our sales team spends all day in, is very annoying... For our purposes we can probably live with it but if we were really sweating call volume then I think we'd get something snappier.

We looked at a lot of alternatives and I was blown away by how un-blown-away I was by anything we looked at.

dbuxton··on Show HN: Language detection as a service
Yes, but you presumably need to get that right in order to encode as UTF-8 and send off to a third-party API...
dbuxton··on Discovering LastPass shared passwords
This is why we have looked at services like https://www.meldium.com/ but unfortunately (because of the way it works) it doesn't work for arbitrary services, only for ones they have done an integration with.

dbuxton··on Ask HN: Who is hiring? (September 2013)
Arachnys - London, UK - LOCAL

Arachnys is a business intelligence search engine for companies operating in emerging markets. We sell a search aggregation and workflow product to some of the biggest companies in the world to help them keep their businesses out of trouble. The Evening Standard (bless them) called us one of "London's hottest techs" so come and find out for yourself.

We're a small team of 10 (5 technical) near Old St roundabout and are looking for a junior dev to join our growing team.

1-2 years' experience working solo, in an agency or for a startup would be ideal. Familiarity with Python is a big plus (extra points for Django) but we'll look at anyone with demonstrable thirst to learn and experience with comparable technologies in different languages.

See https://www.arachnys.com/jobs for application instructions and a full spec. We love candidates who highlight their GitHub contributions - a repo is worth a thousand words.

If you're not sure you match the profile exactly but enjoy working with new technology, big data sets and real problems drop me a line at david [at] arachnys [dot] com.

dbuxton··on Scientist banned from revealing codes used to start luxury cars
I'm an admirer of Ross Anderson but it seems, based on the reporting, the Garcia et al have got themselves into a slightly different situation - I don't think that the chip and PIN disclosures ever resulted in an actual injunction from an actual court, all the banks were doing there was essentially threatening the researchers involved and the academics as a whole. It's one thing to take on card issuers but you can't just write a letter like Dr Anderson's to the High Court and expect them to say, "well that's OK then". That's called contempt of court and it's a crime everywhere in the world.

Dr Anderson has reportedly been injuncted on other occasions[0] but those don't seem to relate to chip and PIN.

I think that the intrusion into academic freedom is lamentable but without any link to the case documents it's hard to say exactly on what basis the interim decision was made. In any event as it's only an interim injunction it may well be overturned at full trial.

My two cents is that the case for disclosure here, while instinctively convincing, is not as urgent as it has been with the vulnerabilities revealed in financial systems. In those cases, for example, banks were refusing to repay money stolen from individuals on the basis that the banks' systems were secure so it must have been the customers at fault. Dr Anderson and others were extremely convincing in showing that this was not necessarily the case. (I don't know if that has filtered through to the financial world at large - are people still being told there are no security holes?)

Perhaps it's just that I don't feel that bad about people having their Bentleys stolen but probably we can wait for trial here (assuming it's not just a strategy by the car manufacturers to bankrupt or intimidate the academics involved).

dbuxton··on Show HN: mailparser.io - extract data from inbound emails
Rather you than me... I set something up using mailgun which has been brilliant, both on the receiving and sending side. For small scale use cases like this it's free too. I send pictures of receipts from my phone to a special email and mailgun POSTs to a tiny Heroku webapp which parses the subject line for amount, currency and date and puts into out accounting software.

You get all sorts of goodies like nice attachment handling and automatic stripping out of quoted text which aren't exactly hard but fiddly.

dbuxton··on How Exercise Can Calm Anxiety
Can anyone actually point me to a study that provides significant evidence for this? As a non-specialist with quite severe meniscal damage from an old rugby injury, swimming has often been suggested to me, but I found it the very most painful and upsetting activity of all. Whereas running (in Fivefingers, for the last four years) has more or less brought my knees back to normal.

I'm not challenging that for some value of "severe" this is true, and I'm sceptical that my own experience represents anything useful at all for anyone else. But my question is: is there actual clinical evidence that this is the case, or is this actually just an old wives' tale?

There are plenty of things online that suggest the opposite[1] - but can anyone who actually knows what they are talking about chime in with the state of the art?

dbuxton··on Why discussions on cyber snooping have been so painful for us
Actually, the 4th Amendment doesn't just apply to US persons - it's a blanket requirement. The restriction of the various agencies' activities to non-US persons is not because (directly, anyway) of any constitutional issue but rather to do with the division of labour between the various agencies - the NSA (et al) is meant to be doing foreign-focused stuff and the FBI to focus on domestic spying.
dbuxton··on Why discussions on cyber snooping have been so painful for us
I went to this expecting to find a slightly puzzled reaction along the lines of, "even given the leaked surveillance, we all know that our own governments are doing similar stuff to us all the time and that we are protected neither by law nor by convention against it".

I know that's a bit of an overstatement but it's particularly amusing to see Snowden sheltered by two of the world's most enthusiastic users of surveillance, namely Russia and China.

FWIW I'm in the UK, where we're a lot luckier than most in terms of accountability, oversight and convention, but don't have an explicit constitutional protection against unreasonable search and seizure. That said, it often bemuses people in Europe to look at the US and see almost no protection for what we understand as a basic right of "privacy".

dbuxton··on The Cost of an ACL Injury
This is absolutely shocking to me. Had my ACL replaced in the UK privately about 8 years ago (no health insurance, paid out of pocket). Total cost was £3000 (+ £600 for initial scan). I could have got it done for free on the NHS but it would have messed up my term time at university.

Like the OP I had meniscal tearing too so more or less directly comparable. (Although obviously 8 years is probably a long time in medical devices so worth bearing in mind).

To put in perspective, that is approximate the same total cost (~$5000) as just _one_ of the pieces of equipment ("Cannula Fast Fix CVD") that the OP lists.

It's one thing if doctors are more expensive because they have to carry higher insurance charges to protect against negligence lawsuits, etc, but that the equipment alone is multiple times the cost seems crazy.

Mental.

dbuxton··on Ask HN: Who is hiring? (June 2013)
London, UK - full-time. https://www.arachnys.com

Arachnys is a London-based, pre-Series A startup that aims to solve the problem of finding relevant, accurate business information in emerging markets. Our product gives even small companies the reach of a global intelligence platform, allowing them to find and understand business data even in challenging environments like the Middle East or Latin America, regardless of language, format or source.

We already have meaningful revenues, selling predominantly to enterprises who need to understand more about their counterparties, customers and distributors globally. Our customers range from vast multinationals to small private intelligence outfits.

We are looking for at least two developers to help us accelerate work on the myriad hard problems that we are solving. Currently we are a team of eight - with four engineers - so you would have a huge opportunity to shape the technological future of the company.

Startup atmosphere, real salary, flexible working hours and quality equipment provided.

We are a Python shop so expertise in that (and, inevitably, JavaScript) is a strong advantage (Django is our framework of choice). We have a number of different application components, including multiple distributed applications, so experience orchestrating large numbers of machines with tools like Chef or even Fabric would help. Above all though we want smart, multitalented people who can think for themselves and take pride in their work.

Willing to consider remote applicants only if they can commit to at least 1-2 days/week in London in a normal week.

To apply: email founders@arachnys.com to introduce yourself and your Github profile (or some other code you've authored or contributed to).

dbuxton··on Hijacking airplanes with an Android phone
Not entirely on topic, but I also remember seeing something a few years ago about how you could actually telnet (sic) into some airliner flight control computers if you were able to splice into the physical cables (which run under the floors). Something about not using ssh because it messed up the prompts... Will have to find it.
dbuxton··on Ukko Mobile From Helsinki Eliminates Data Roaming
I use Tru (formerly Truphone) which covers UK, US and Oz, I assume through the sorts of deals that these guys have pulled off.

It's a fabulous idea but badly executed (despite the fact that they have raised oodles of VC money) with poor call quality and slow (2G) data speeds. Still, so much easier than buying a SIM in the US. Also, has the wonderful property that you can call someone who is physically in the US on their UK mobile number for free for both parties - for which incoming call (for those of you who don't know how backwards the US cell market is in comparison with regulated Europe) a US cell customer would normally have to pay!

That said, if you mainly travel to the US and don't want to deal with T-Mobile or Virgin or whoever, I heartily recommend them.

dbuxton··on Dear Startups: stop begging investors and pitch your clients
This is just wrong. Pitch when used as a verb can - and sometimes must - be used without "to" ("He pitched me a new startup idea" vs *"He pitched to me a new startup idea"). As a noun it does need "to".
