I suspect the sleep.me chilipad systems (ooler/dock pro) would work pretty well with adjustable beds since they just run a pair of insulated water hoses to a capillary tube network in a mattress pad. Further, if the hose routing didn't work for you out of the box with those you could DIY something else pretty easily since they use off the shelf connectors (https://www.cpcworldwide.com/General-Purpose/Products/Multil...)

On the bed heating/cooling front, you might try the Ooler series from sleep.me

The older generation Oolers use bluetooth and there are a fair number of integrations including an [MQTT bridge](https://github.com/turmoni/ooler-mqtt-bridge) and a [HomeAssistant integration](https://github.com/PostLogical/ooler).

I'm less familiar with their latest generation which uses WiFi, though there [seems to be an API](https://docs.developer.sleep.me/api/ ) available for it now.

CRXcavator is a pretty useful tool for scoping out Chrome extensions like this: https://crxcavator.io/report/mabdjppmcjpjploliggpbonahnjjlgk...

Similarly, Urlscan.io is pretty useful for scoping out sketchy links like the one in the extension's html: https://urlscan.io/result/d95c1113-a446-4c94-8b1f-dd7d530531...

I hit a similar problems when sending automated internal emails to a Google Groups address at my company. The problem was fixed by adding the following footer: "To unsubscribe, email <my-email-address>."

It's issued under a Durbin exempt, commercial, prepaid BIN.

We're trying to build a system where companies feel comfortable giving cards out to all of their employees and then adjust the limits upwards as they build trust internally. The ad-hoc requests features from this example might be best for new/temporary employees or large purchases. Over time I'd hope that most employees will actually have a monthly budget and thus a greater degree of autonomy.

We actually use the interchange revenue that would be going towards rewards points to pay for the costs of building/running the product. There may be enough left over to do a rewards program in the future, but for now the product is the points. :)

I'm a founder at KarmicLabs. I used to expense stuff on my personal card at a previous company, but I don't think the points made up for the times I lost receipts or didn't bother to expense small stuff. YMMV.

Karmic Labs | San Francisco (SoMa) | Onsite | Backend (Systems/API), DevOps, Frontend

We're building the first extensible payment card platform for teams.

It's called Dash and it's powered by Mastercard. Dash is designed to help teams distribute funds in real-time and communicate about spending (auto-magic-accounting). We're also building real-time APIs to allow others to build plugins for new and interesting use cases, and accounting.

We value:

* Shipping product, delighting our users, elegant systems, and each other.

* Using first principles, code reviews, testing, collaboration, and mentorship.

We're looking for someone who is excited by:

* Bringing new ideas and abstractions into an existing industry currently dominated by older products and larger companies.

* Forming clean architectural patterns and beautiful APIs to handle messy, underspecified payments backends and communications problems.

* Having the opportunity to step up as tech-lead or to own parts of the codebase.

We're currently building with Python 3, Flask, React, Postgres, and AWS.

Our team includes experience from the founding teams of Netscape and Pinterest, executives from Visa and American Express, a seasoned venture capitalist, two high school dropouts, and a Physics PhD. Standard startup perks included (competitive salary, insurance, home cooked meals, etc..)

Karmic Labs - Full Time in SF - https://karmiclabs.com

We are a small, diverse team working to revolutionize the way teams communicate about money and expenses, from our small office in the South of Market area of San Francisco. We’re looking to expand our team with dynamic, creative, focused individuals, who can learn new frameworks and systems quickly, and who can contribute their input and ideas into our company and our platform.

We believe that everyone in the workforce should get a smart debit expense card from their employer, and that every business owner should understand their expenses as they happen. We're building a debit card platform that allows small businesses to have dynamic financial controls and trust levels, accountability by default, and real-time expense management. Our private beta went live with Mastercard at the end of last year.

We're a small team from a diverse set of backgrounds (Pinterest, V.C., Netscape, Thoughtworks, Amex...) based in our converted-Victorian office in SoMa.

We strive to have an open and accepting culture. On the technical side:

* We're building our APIs with Flask on Python3 and using Postgres, Redis, Nginx, and AWS.

* We're building our Web apps with AngularJS and Sass (mobile app as a web/native hybrid).

* Our web infrastructure is deployed with Ansible an uses Nginx, Sentry, and an ELK stack for logging.

* We use Git + Phabricator for code reviews and TeamCity for CI. We like linters and unit tests.

We're looking for:

* Design, UI/UX - We care deeply about UX and are looking for a designer who has a passion for building great interfaces.

* Frontend - We're looking for the type of person who reads all of the new browser API specs and is excited by ServiceWorkers. * Backend - Do you have a passion for building well factored code and designing great APIs?

* DevOps - We're obsessive about infrastructure automation.

KarmicLabs - San Francisco, CA - Fulltime

We're building an API first corporate card platform for small businesses, and we’re on a mission to make traditional expense reporting a thing of the past.

* We're taking an API first approach and building with modern tools like Python3, Flask, Postgres, Ansible, AWS, AngularJS, and git. * We’re solving real world problems that millions of businesses face every day. * We have a small and tight knit team of engineers including founding engineers from Pinterest and Xfire. * We raised our first round a few months ago and provide meals, health/vision/dental insurance, and standard startup perks. * We’ve just moved in to an awesome office in SOMA near 8th and Folsom.

We’re currently looking to expand our small engineering team hiring DevOps, Generalist, and Frontend engineers.

To apply, send us an email: jobs at karmiclabs dot com; be sure to tell us a bit about yourself and include a link to your github account or something that you’ve worked on recently.

These are really easy and fun to put together. I'd highly recommend it for a weekend project.

Here's one that I built running with a sample of Americium 241 from a cheap smoke detector: http://bit.ly/UDWpc0

Here's a different one running with a bit of Thorium containing lantern mantle http://bit.ly/1Annrp5

You can also try with thorated tungsten welding rods and other household sources of radiation.

KarmicLabs: Payment Cards as a Service - fulltime SF

We're building a SaaS service that lets small businesses issue configurable expense/purchasing cards to their employees. Cardholders can use our mobile app to handle receipt capture and expense reporting during transactions (instead of at the end of the month) or request approval for budget changes and large purchases. By issuing the cards ourselves (over the existing payment networks) we can get significantly more data and expose more control parameters than we could by linking to existing cards.

We recently raised our first round and are looking to make our second and third fulltime engineering hires. We've got interesting problems involving security, authentication, fraud detection, and user interfaces.

Stack includes: Python3, AWS, Ansible, AngularJS, SCSS, Redis, and PostgreSQL.

Latency sucks. You can apply this type of touch-click speedup on a site for other browsers with a bit of JS.

https://gist.github.com/cagerton/7948779 (disclaimer: proof of concept, etc. )

Using the same browser for regular browsing and TOR browsing is a horrible idea. As it turns out, browser controls for stored state are not intuitive. For example, Google says it's okay that tracking-ids leak from regular browsing mode in to Incognito mode - just not the other way around. Huh? https://code.google.com/p/chromium/issues/detail?id=311296 (same thing with Mozilla)

I'd really like to see a Tor browser distribution that spins up a clean VM each time you open a new session. Until then, the guys building the Tor Browser Bundle are doing a pretty decent job.

San Francisco, CA - CardSnip.com

We're collapsing the small & medium business financial stack with smart purchasing cards, analytics, and data-oriented payment processing. We do all this without breaking the existing merchant banking relationships and using quirks of the existing networks to our advantage. We're currently a small team, but we're getting close to closing our first round and we're looking to bring on some generalist engineers with both web and backend experience.

Buzzwords: Python3.3, Django, Tornado, Postgres, d3.js, scss, lxc and Salt Stack. Oh, and we have three 3d printers in the office.

Follow up: I emailed [email protected] asking them to update their configuration and linking them to https://wiki.mozilla.org/Security/Server_Side_TLS (Thanks for posting that, jvehent)

This is sketchy. The new server no longer attempts to provide any forward security.

For the old (now revoked) site, Chrome would use: TLS_DHE_RSA_WITH_AES_256_CBC_SHA. For the new liberty.lavabit.com site, Chrome will pick TLS_RSA_WITH_AES_256_CBC_SHA with the new server. This means that instead of having to factor a 1024 bit dh parameter for each session, the FBI/NSA/etc will be able to be able to decrypt traffic to this server when they get the private key.
