Understanding Dataset Shift

  • The problem of dataset shift can stem from the way input features are utilized, the way training and test sets are selected, data sparsity, shifts in the data distribution due to non-stationary environments, and also from changes in the activation patterns within layers of deep neural networks.
  • Clearly, the overall relationship between the inputs and outputs changed due to the new socio-economic environment, and, if these are not reflected in our variables (such as having a dummy variable for the date that the financial crisis occurred and training data before and after this date) then our model is going to suffer the consequences of concept shift.
  • Sample selection bias: the discrepancy in distribution is due to training data having been obtained through a biased method, and thus do not represent reliably the operating environment where the classifier is to be deployed (which, in machine learning terms, would constitute the test set).

Why we ditched story points to be more value-oriented

  • 1-week sprints were making everything worse due to this fact when we finished features that weren’t good enough to put in production and were coming back to haunt us.
  • We always like to iterate on processes to improve it and reduce friction at maximum, so everybody is comfortable working and focusing on delivering as much value as possible.
  • Every user story or feature has a team behind, design, product, development, and everybody is needed to accomplish it.
  • In the case of engineering tasks and reducing technical debt, we follow the rule ‘leave the campground better than you found it.’ I have adopted that rule for years since I read Clean Code, but all the team must stay in tune, so every time we do a feature, we can clean up the area where we are going to work.

Twitter will now let you post iOS Live Photos as GIFs

  • Live Photos are one of Apple’s signature camera options on iOS, making your photos look like one of the living photographs in Harry Potter.
  • But if you’ve tried to post that Live Photo on Twitter, it would render as a still photo, taking away some of that magic.
  • You could use an app to convert that Live Photo into a GIF and post that new GIF on its own, but that might be more work than you’d want to do.
  • I think Live Photos are really fun, so I hope people use this feature to add a little more life to the photos they post on Twitter.
  • At the very least, this new feature let me give the world another GIF of a goat.
  • Command Line delivers daily updates from the near-future.

#discussIf you work as a dev for a product team, what's it like?

  • Sometimes people work weirder hours if it makes sense for them (a co-worker was in Japan for a month and decided to start their workday at 6am Japan time, for example) We chat online and use conference calls for when something face-to-face feels like a better fit.
  • We are a small team, so during crunch times, juggling bug fixes, support requests, "can you quickly squeeze in this small quick feature" (lol) as well as working on whatever our current "big long-running feature" is, can sometimes be very daunting, and we're always trying to find ways to manage this workload better, but I don't think we've found the magic bullet yet.
  • Since I am managing people I think it's partly my responsibility to research and bring things back to the team that I think could be good for us.

How to turn on automatic updates on your iPhone for iOS and apps

  • Automatic updates are an essential part of keeping your iPhone healthy, safe, and secure.
  • Apple and other software developers routinely release updates that fix bugs, resolve security issues, and introduce new features.
  • Automatic updates should be turned on so your iPhone always stays up to date, without any effort on your part.
  • The good news is that automatic updates should already be turned on by default — unless you turned this feature off at some point in the past.
  • Here's how to turn it back on.
  • The most important update to turn on is the one for your iPhone's entire operating system.
  • It's also a very good idea to ensure that your apps can get updated automatically as well, both to make sure you have the latest features and capabilities, as well as to ensure your apps are secure and working properly.

Google's Chrome browser will now alert you if you enter a password that hackers have already stolen

  • People using Google Chrome may encounter a new warning the next time they enter a password: The browser will now alert them if the password they typed in has previously been stolen in a data breach.
  • The new feature, announced by Google on Tuesday, is meant to protect more people against hackers who aggregate stolen passwords and use them to maliciously access people's accounts.
  • In a blog post, the Chrome engineers behind the feature explain that Google uses hashed and encrypted copies of passwords, and checks those against passwords people type in using an encrypted key.
  • More than 4 billion records have been stolen by hackers over the past decade alone, and data breaches are becoming increasingly common.
  • According to cybersecurity experts, hackers maintain networks on the dark web specifically for sharing stolen passwords.
  • Read more about how Chrome's new feature works here.

Visa expands its suite of Visa Direct remittance partners with TransferWise

  • The digital remittance provider will launch support for Visa Direct, the brand's near-real-time push payment offering, and allow customers to move money to debit cards in real time.
  • The partnership follows similar deals with both legacy remittance providers like Western Union and MoneyGram as well as digital upstarts like Remitly.
  • Integrating Visa Direct could help remittance players like TransferWise position themselves at the forefront of the crowded digital remittance space.
  • But the space is packed, with digital providers like TransferWise, Xoom, Remitly, and WorldRemit competing for a share of the market against legacy giants like Western Union and MoneyGram that are boosting their digital offerings.
  • Enabling payments through Visa Direct could help allow TransferWise to ensure it offers an identical feature set to its competitors, which might help it attract customers while allowing it to improve its speed and cost — two features consumers value in a remittance product.

Twitter will now preserve JPEG quality for photo uploads on web

  • Twitter is changing the way it processes uploaded images, and the new way of doing things will be much-appreciated by any photographers sharing their work on the platform.
  • Twitter engineer Nolan O’Brien shared that the platform will now preserve JPEG encoding when they’re uploaded via Twitter on the web, instead of transcoding them, which results in a degradation in quality that can be frustrating for photo pros and enthusiasts.
  • But once users click through, they will get the full, uncompressed (at least, not additionally compressed) image you originally uploaded, provided it’s a JPEG.
  • The example above posted by O’Brien is actually a really illustrative one when it comes to showing what kind of detail and quality can be preserved when Twitter doesn’t further compress or transcode your JPEG photos.
