Tue, 23 May 2017 01:13:45 +0000 en-US hourly 1 CloudFlare states Adafruit not part of the @Cloudflare issue(s) #cloudbleed @adafruit Mon, 27 Feb 2017 20:13:27 +0000


tl;dr CloudFlare has stated that Adafruit’s sites were *NOT* part of the CloudFlare issues.

Adafruit uses CloudFlare’s proxy service to reduce server load and provide a faster browsing experience for customers using the Adafruit blog and shop.
CoudFlare announced that a major leak was detected in their network which affected a number of sites using their proxy service (

According to CloudFlare, only a small number of sites were affected. After contacting them, CloudFlare engineering confirmed that *NONE* of Adafruit’s domains were in the affected zones.

Feb 24, 5:49 PM GMT

Hi, Thanks for contacting Cloudflare Customer Support. We have notified all the customers the were affected by the memory leak and I can confirm the zones on your account were not one of them. Our CTO John Graham-Cumming has published all of the information we have here:

Please let us know if you have any other questions.

Kind Regards,

– Cloudflare Senior Support Engineer

Adafruit takes protecting your data very seriously, we took the following steps in an abundance of caution:
Disabled CloudFlare proxy service on the Adafruit Accounts system.
To defend against the possibility that active session cookies were leaked, we closed all active user sessions across Adafruit’s websites.

We suggest:
Check the list of potentially affected sites ( and change your password for any of those sites.
Change your passwords (we always recommend that you use strong and unique passwords for each site that you use; please don’t reuse your Adafruit website anywhere else).

Adafruit has made a pull request to the folks that list us on the “sites-using-cloudflare” ( list including the note from CloudFlare support indicating that we were not affected by the memory leak.

Adafruit DNT (Do not track) @adafruit #DNT @eff Tue, 10 Jan 2017 01:00:00 +0000


Adafruit cares deeply about privacy, security and human rights – our community and customers trust us with their data and it’s up to us to demonstrate the type of company we are and the type of people we are. We like to say “be excellent to each other” – those are words, and there are also actions.

A while ago we added support for DNT (Do Not Track) to our properties and will continue to do so. Supporting DNT is really about keeping users’ online behavior from being followed across the Internet by behavioral advertisers, analytics companies, and social media sites. It’s a little bit of coding, a little bit of tech as far as the approach and most of all, it’s a policy, promise and framework so users can know and choose what is tracked and what is not. Ideally all companies would respect DNT but not all do, and this is an opportunity for Adafruit to show its work and encourage others as well. (Adafruit’s latest privacy policy is here).

It will never be perfect, but this is a start and we’ll keep at it. Here are more details on DNT, Adafruit, the EFF and using tools like Privacy Badger as well as setting DNT in many of the browsers you may use. This is by no means a for-sure way to be super secure, super private or anything like that, but it’s a start, and we hope others, specifically educational companies like Adafruit, devote some time and resources to help educate their community and customers. Let’s do this!

What is DNT (Do not track)?

Let’s get started with having folks much smarter than us, the EFF (Electronic Frontier Foundation), explain exactly what DNT is and why it’s important.

Do Not Track (DNT) is a way to keep users’ online behavior from being followed across the Internet by behavioral advertisers, analytics companies, and social media sites. It combines both technology (a way to let users signal whether they want to be tracked) as well as a policy framework for how companies should respond to that signal.

Online tracking began in the late 1990s but has expanded massively in the last decade. Advertising is the main business model financing media production on the open web, and the drive to increase revenue by targeting ads to selected users has led to the creation of a plethora of companies dedicated to monitoring our clicks, searches, and reading habits as we move around the Internet. While technologists have long worried about the privacy implications, it was the Wall Street Journal’s What They Know series in 2010 that brought widespread public attention to the issue by showcasing how marketers gather data on online users.

Much of this tracking happens via cookies. The HTTP cookie, invented at Netscape in 1994, came into life as an innocent and essential tool for the web; cookies make possible “stateful” user interfaces such as user accounts and logins, multi-page forms, or online shopping carts. But cookies also allow sites to store a unique ID in your browser, and therefore to track you—and if a company is present on multiple websites, it can track your visits to each of those sites. In other words, a company can use cookies to construct a detailed overview of users’ activity. Many people feel this is an invasion of their privacy, and want to be able to block, limit or delete their cookies.

Unfortunately, more recent technologies have fostered the development of cookie-like tracking systems that are harder for a user to detect or delete, and can provide marketers with a rich source of data about an individual. Today, online tracking companies use supercookies and fingerprints to follow people who try to delete their cookies, and the leakage of user IDs from social networks and similar sites has often given them an easy way to identify the people they were tracking. In December 2015 EFF launched an updated version of its Panopticlick site which enables users to check their browser’s resistance to different tracking techniques.

You can read more on the EFF’s site and the Wikipedia entry for some more details and history of DNT.

How to enable DNT (browsers)

Good news, bad news. Ok, so browsers have “DNT” features, but really, you’re best off installing EFF’s Privacy Badger, however, we’re going to go through some of the browsers first. If you want to skip all this, go for it, the Privacy Badger is at the end either way.

Some browsers have built in DNT, however it doesn’t always work and some “browser companies” also are mostly funded by advertising and tracking so it’s unlikely that Chrome will really, ultimately, do an excellent job of not-tracking Google search/YouTube, etc, etc. Google’s ad business accounted for 89 percent of revenue, or $76.1 billion… “No one wants to face the reality that this is an advertising company with a bunch of hobbies”. And by default, don’t expect browsers to all come with DNT enabled. For these examples we’ll just look at Firefox, Safari and Chrome – there are others and lots of OSes, including mobile, this is to just get ya’ started.


Adafruit 2083
First up, make sure you have the latest browser, for Mozilla Firefox (macOS X) 1/8/2016 the version was/is 50.1.0.

After installing Firefox, click the little hamburger looking icon in the upper right and click preferences.

In Preferences, click Privacy (left bar) and click “manage your Do Not Track settings.” Click “Always apply Do Not Track”. Firefox has a read more link that talks about this too.

Adafruit 2088
You can also make the block list a little more stricter, go ahead and do that too “You can choose which list Firefox will use to block Web elements that may track your browsing activity.” If some sites do not work any more, you might need to adjust these settings. There are additional options on what/who can track you in private windows and Firefox uses “” – be sure to review what/who it’s blocking, they also offer a VPN service, we’ve not tried it out though.


Next up, Google Chrome (Mac) latest version as of 1/8/2017 is Version 55.0.2883.95 (64-bit).

Same as before, click the 3 dot-burgery icon and click settings.

Chrome Advs
In settings click “Show advanced settings…”

Chrome Clicked
Chrome Warning
Click “Send a Do Not TracK’ request with your browsing traffic. Chrome immediately pops up a window to read, it seems to say “some” websites are still going to track anyway, ok. And Chrome has a link to read more about this as well.


Safari About
Last up, Apple’s Safari, the latest version 1/8/2017 is Version 10.0.2 (11602.

Apple Site
As far as browsers go, Safari is a little unusual, some of the leading features, at least as of 1/8/2017 is privacy, security and default options for privacy and not-tracking. Screenshot is above just in case anything changes later 🙂

Safari Prefs
To turn on DNT on Safari, at least the desktop version, go to Safari > Preferences.

Safari Ask
Click Privacy and check off “ask websites not to track me”.

It appears that Safari on the desktop may by default block “some” 3rd-party cookies, and on iOS Safari by default may block even more, but since Apple control iOS, it’s unclear how or if Chrome for iOS for example can do the same things, here’s a article about this, we’ll see what more/what else we can determine. Our guess is that Apple likes saying they don’t track you by default and Google likes tracking you if you’re using a Google product/service so it’s some type of weird symbiotic look-the-other-way, at least for now.

Safari Help
If you click the little round question icon, Safari has a help system that explains what/how website tracking is, again, it says it’s up to sites to honor the request.

Ios Privacy And Security-1
On iOS it does appear that DMT is on by default, at least it was for our phone, there were some additional settings in Privacy that we turned on as well.

There are additional setting in iOS for Privacy and ads, check out the settings and review Privacy and the Safari settings.

Just install the EFF’s Privacy Badger

Ok so all these browsers have some type of DNT setting that can be enabled, but most of them just say “well, it’s up to sites to honor it” – that’s really not going to happen, so what can you do? Install the EFF’s Privacy Badger, this will force the websites you visit not to track you, or at least it’s another layer you can add that will at least make it more difficult.

What is Privacy Badger?

Privacy Badger blocks spying ads and invisible trackers.

Privacy Badger was born out of our desire to be able to recommend a single extension that would automatically analyze and block any tracker or ad that violated the principle of user consent; which could function well without any settings, knowledge, or configuration by the user; which is produced by an organization that is unambiguously working for its users rather than for advertisers; and which uses algorithmic methods to decide what is and isn’t tracking. Although we like Disconnect, Adblock Plus, Ghostery and similar products (in fact Privacy Badger is based on the ABP code!), none of them are exactly what we were looking for. In our testing, all of them required some custom configuration to block non-consensual trackers. Several of these extensions have business models that we weren’t entirely comfortable with. And EFF hopes that by developing rigorous algorithmic and policy methods for detecting and preventing non-consensual tracking, we’ll produce a codebase that could in fact be adopted by those other extensions, or by mainstream browsers, to give users maximal control over who does and doesn’t get to know what they do online.

Read more and download.

How does it work?

When you view a webpage, that page will often be made up of content from many different sources.  (For example, a news webpage might load the actual article from the news company, ads from an ad company, and the comments section from a different company that’s been contracted out to provide that service.)  Privacy Badger keeps track of all of this.  If as you browse the web, the same source seems to be tracking your browser across different websites, then Privacy Badger springs into action, telling your browser not to load any more content from that source.  And when your browser stops loading content from a source, that source can no longer track you.

At a more technical level, Privacy Badger keeps note of the “third party” domains that embed images, scripts and advertising in the pages you visit. If a third party server appears to be tracking you without permission, by using uniquely identifying cookies (and, as of version 1.0, local storage super cookies and canvas fingerprinting as well) to collect a record of the pages you visit across multiple sites, Privacy Badger will automatically disallow content from that third party tracker. In some cases a third-party domain provides some important aspect of a page’s functionality, such as embedded maps, images, or stylesheets. In those cases Privacy Badger will allow connections to the third party but will screen out its tracking cookies and referrers.

Ok, so here’s how to install, we’re going to show Firefox, it’s also supported in Opera, but it’s not available for Microsoft Edge, Firefox Mobile or many/most mobile browsers. For Chrome it’s basically the same thing, visit, click install.

Privacy Badger – Firefox

Make sure you have the latest version of Firefox and then head over to:

Ff Badger
Click “Install Privacy Badger and Enable Do Not Track”.

Ff Allow Pb
You may need to click “allow” to allow the software to be installed.

Pb Howto Ff
After installed, you may be taken to a quickie how-to on how to use Privacy Badger, you’ll also see cute little badger in your address/toolbar.

Ok, now the fun begins, let’s visit some sites, since this article is about Adafruit’s DNT, let’s see how we do. As you browse site the little Badger in the upper left will tell you the tracking attempts and tracking on a site.

Here’s Click around our site, try turning on and off DNT in your browser’s settings and see which sites, including Adafruit respect DNT and which ones do not. See what sites are tracking you, and over time, turn the ones on and off and block them in Privacy Badger if you choose not to be tracked.

Dnt Adafruit Video
For Adafruit, there will be times when you’ll need to go watch a video on Youtube or enable tracking if you want to watch a video on a site, some sites/services do not comply it DNT and you’ll be presented with the choice of viewing the videos, etc. or not.

Pb Cnn
Ok, so let’s look at a site that is tracking, we’ll pick an easy one, 59 trackers and it looks like their site uses Adobe Flash and has a security issue, ok – good to know, good to block.

Try other sites, email the site owners and ask them to respect DNT if they do not and please help someone you know that might not be so techy protect their privacy online. We’ve included many of the resources we referred to in the article, below, enjoy!

Keeping Your Account Protected Tue, 01 Nov 2016 17:32:26 +0000

Hey folks, some of you received this email today, this is our blog post with all the details as well.

tl;dr (too long, did not read)
We’re asking certain Adafruit user accounts from 2014 and before to reset their passwords as an added security precaution.

Tell me more
We’ve recently become aware of a vulnerability in our legacy authentication system that could have enabled malicious attackers to access information from certain user accounts created in 2014 and before.

The vulnerability could have allowed an intruder to have had access to some usernames, some email addresses, and some hashed passwords from these older forum accounts. We do not believe this issue affected Adafruit store accounts or payment or billing information (Adafruit does not store credit cards, only authorizations). The issue was disclosed by a security researcher as part of a vulnerability disclosure. Following disclosure of the issue, the researcher confirmed user information to demonstrate the vulnerability. We have no reason to believe that any user information was used for fraudulent purposes.

The vulnerability in question involved taking advantage of a weakness in the Adafruit Job Board, a public job offerings forum on the Adafruit website. The Adafruit Job Board did not store resumes or any additional information other than the content of its users’ public posts. From there, an attacker could take steps to gain unauthorized access to user information in our customer support forums: usernames, emails and hashed passwords from older forum accounts. After conducting a thorough internal investigation that included review of our logs, we found no evidence of any other party that might have taken advantage of this vulnerability. We are also currently unaware of any actual misuse of user information.

Although we currently hash all user passwords using bcrypt in an effort to prevent malicious attackers from misusing passwords, certain older passwords that had not been updated since 2014 were hashed using the less robust MD5. Even if you did not use the Adafruit Forums, an account may have been created when you signed up.

To err on the side of caution, we have set up a process to help automatically reset any MD5-hashed passwords that may have been implicated by the vulnerability. When you log in to your account, you will receive a prompt instructing you to create a new password. If you do not receive a prompt, we do not believe your account was affected. However, you can always reset your password by logging into your account, navigating to the account settings page, and following the directions there for changing your password. If you use your Adafruit Customer Support Forums password for any other site, we also recommend resetting your password for those sites. We encourage you to use strong passwords and to not to reuse passwords on other sites.

As a reminder, for your security, we will never send you a link to reset your password as part of a security alert and our customer support team will never contact you asking for your password. If you receive an email of this nature, or otherwise suspect that someone is attempting to gain access to your account or solicit your personal information, or have any other questions about this process, please contact us at

We would also like to thank all individuals who have and will contribute to the security of our users by disclosing vulnerabilities to us responsibly (

We apologize for the disruption and the extra work this requires from you for these added security measures.

State of the live streaming’ Facebook, YouTube, Twitch and now Twitter (Periscope) Thu, 20 Oct 2016 13:23:15 +0000

Adafruit 1814
Last night we live streamed to 4 social networks/services – Facebook, YouTube, Twitch and now Twitter (Periscope). Periscope recently announced it supports RMTP, which means video broadcasting tools can use that to broadcast to instead of using the phone directly. We were able to do what we believe was the first ever 1 hour “quadcast” to 4 services of our weekly live electronics show, “ASK AN ENGINEER”.

Here’s the Periscope version (video), over 1,000+ live viewers.

Facebook was about 900+ total unique live viewers (however, says “9,000 reached” at this time), YouTube about 280+ live viewers, Twitch was about 50+. Our show happened to be before the debate so these numbers will go up and down each week.

We’ve also heard “crowdfunding” companies are going to be offering a live video streaming service too at some point, that’s a really good idea – backers could see the progress “live” at times and it would like eliminately a lot of the issues with hardware projects when the backers can ask questions directly to the teams.

Live video is part of the “good information is advertising” strategy good companies will have to develop. If you make things, share it, live, with your community.

1790 – Patrick Matthew, Scottish originator of the first full and complete hypothesis of natural selection in 1831, is born.


Patrick Matthew was a Scottish landowner and fruit farmer, who contributed to understanding of horticulture, silviculture, and agriculture in general, with a focus on maintaining the British navy and feeding new colonies. He published the basic concept of natural selection as a mechanism of evolution in an obscure appendix to his 1831 book On Naval Timber and Arboriculture.

Matthew failed to develop or publicise his ideas concerning natural selection; Charles Darwin and Alfred Russel Wallace were credited with publishing the theory of evolution by natural selection in 1858; and historical analysis shows no firm evidence that either Darwin or Wallace encountered Matthew’s earlier work before he contacted them in 1860. Darwin then publicly acknowledged that Matthew’s brief statement in the appendix had anticipated by many years the principle of natural selection in On the Origin of Species.

ServInt’s profile on Adafruit – @servint #servint #makerbusiness Thu, 19 Feb 2015 05:00:01 +0000


ServInt’s profile on Adafruit (and check out the photos of where Adafruit lives!)

Adafruit is one of the fastest growing private companies in the US. The company, founded by MIT engineer Limor “Ladyada” Fried, was created as the best place for Do It Yourself electronics online. Very quickly they lived up to their goal and attracted enthusiasts from around the world. Today, they have hundreds of educational videos and lessons and sell thousands of different components and kits for people of all skill levels. They’ve grown to reach over 11,000,000 (yes, that’s 11 million) page views, 2 million of them unique, every month.

If you’re the type who takes apart your remote control, video game systems, or computers in order to see how they work, then you definitely need to check out Adafruit. They have plenty of cool things for you to work on, like DIY VR goggles, a portable game console, and Raspberry Pi products. It doesn’t matter if you’re an enthusiast or a curious newcomer, they have something for you! There’s a reason they’ve been featured by Newsweek, Popular Mechanics, NPR, and more.

Adafruit has been with ServInt since 2012. Timor told us a little bit about their time with us, saying, “If you really want to talk about ‘scaling’ – Adafruit went from $187,000 in revenue in 2006 to $33m in revenue in 2014, we are not slowing down. Servint has allowed us to grow our store, our learning system, and a popular site – they’ve had something to fit our needs for every stage of our company. Servint’s dedicated 24/7/365 support and offerings are why we’ve been with them for every single year of Adafruit’s rapid growth!”

What interests reddit? @reddit Wed, 18 Feb 2015 05:00:17 +0000

What interests reddit? – Government, women and more…

Many redditors seem to have an interested in talking about the government (dark blue). However, their interests in the topic appear to stem from a diverse set of sources. The two largest groups of features are defined by their secondary alignments with discussion of “state” and “women”.

Apparently women are a very common topic of discussion on reddit – perhaps not surprising for a forum (like many on the web) populated disproportionately by young men. However, while everyone seems to be talking about women, what’s strikingly obvious is that not everyone is having the same conversation.

One of our biggest sources of traffic was reddit, still to this day, was from this post “PizzaNet” an operating system that Pizza Hut developed.

We also see a lot of traffic coming from here and here.

This is where Adafruit lives – @servint #Webhosting #servint Thu, 12 Feb 2015 13:46:06 +0000

Here are some fantastic and amazing photos provided provided by ServInt our trusted partner for smart hosting for smart websites – VPS, dedicated and cloud! Special thanks to John Kastronis, ServInt Community Manager, for helping to make this happen – everyone, this is where Adafruit lives 🙂

Here is the cage where we have our server (among many others) in. Our server is in the row furthest to the right. You can see a glimpse of Brian Loomis, the head of provisioning, off in the corner there. He was the one who located the actual servers and showed where to take pictures.

A better look at the row itself.

Now, let’s take a look at the rack our Flex ONE server is in.
We are in Rack G in slots 14 & 15.


These are close ups of our actual Flex ONE server.


Business ends 🙂

State of the fruit – Here are some social media stats and more 1/1/15 to 2/1/15 Fri, 06 Feb 2015 05:00:57 +0000

Adafruit 4240

We measure everything at Adafruit, from shipping speed to YouTube subscribers. Our team has a massive report we share each month that has all our online efforts and we have a PDF overview for the press folks who ask about us. Here’s a high level overview of just some of the things we measure. We’ll post another one of these mid year, or year end to compare and see how we’re doing. Adafruit does not take ads on our site and never will (or spam!), pageviews are still important to us because it means we’re doing interesting things that people want to check out. We’ve decided not to have a marketing team or group and focus on our customer service, shipping speed, new products, new web site features, weekly shows, videos, tutorials and more. Maybe we’ll do what is considered “traditional marketing” one day, but our customers and community and team here really enjoy how we’re doing things now, we’ll keep going 🙂

Our site was down we are working with our provider @servint to avoid this happening again @ServIntStatus Mon, 02 Feb 2015 17:03:16 +0000





Hey folks, some of our site was down for a couple hours today, we’re very sorry about that and we thank you for your patience & support on this very exciting Pi 2 launch day. We’re working up a post server meltdown plan to make sure it does not happen again, we’re working with our provider ServInt who we’ve been with for years as well, this was very rare. We did have this problem before when our server needed to be rebooted we are told there is a “5 hour quota calculation” where the site is down the entire time, we can’t have that happen, ever – so we’ll work on a solution with ServInt. ServInt please have someone reach out to us if you see this post as well.

Server maintenance for 15 mins Monday 8/25/14 – 4am (ServInt Status) – @ServIntStatus Sun, 24 Aug 2014 22:36:50 +0000

Picture 4

Server maintenance for 15 mins Monday from 4am to likely 4:15am … ServInt Status.

On Monday, August 25th at 4am datacenter local time we will be performing a series of reboots across our entire Flex VPS, Flex Dedicated and SolidFire customer base to improve the security and stability of systems. The maintenance will accomplish two important tasks:

  1. To reboot onto a kernel that addresses intermittent stability issues that have been seen on the most recent vendor-supplied Linux kernels.
  2. To install a stable, *live kernel image patching system* – part of the series of recently announced service upgrades – that will limit the need for future reboots.

We believe that the new kernel will provide a marked improvement in stability, and are particularly excited about the addition of the live kernel image patching system. In rare circumstances, kernel updates that address stability may still require future reboots. However, most required kernel updates we issue address security issues. Following this maintenance, we will be able to provide most kernel security updates *without a reboot*.

We expect the maintenance window to last approximately two hours, and during that time, your server is likely to be inaccessible for approximately 15 minutes from the time of reboot.

We’ll update this post if anything doesn’t work out.
