### AI overview

This Google Research article explains software techniques for mapping mixed-input matrix multiplication onto NVIDIA Ampere hardware. It describes using lower-precision weights with higher-precision inputs, data-type conversion, and layout transformations to support weight-only quantization. The authors report minimal software overhead and performance close to peak hardware capabilities, and state that the techniques were released in the open-source NVIDIA/CUTLASS repository.

### Source excerpt

Posted by Manish Gupta, Staff Software Engineer, Google Research AI-driven technologies are weaving themselves into the fabric of our daily routines, with the potential to enhance our access to knowledge and boost our overall productivity. The backbone of these applications lies in large language models (LLMs). LLMs are memory-intensive and typically require specialized hardware accelerators to efficiently deliver tens of exaflops of computing power. This blog post shows how we can start addressing the computational challenges by utilizing memory more effectively. The bulk of an LLM's memory and compute are consumed by weights in matrix multiplication operations. Using narrower data types reduces memory consumption. For example, storing weights in the 8-bit integer (i.e., U8 or S8) data type reduces the memory footprint by 4x relative to single-precision (F32) and 2x relative to half-precision (F16) or bfloat16 (BF16). Furthermore, previous work has shown that LLM models running matrix multiplications with weights in S8 and input in F16 (preserving higher precision of the user-input) is an effective method for increasing the efficiency with acceptable trade-offs in accuracy. This technique is known as weight-only quantization and requires efficient implementation of matrix multiplication with mixed-inputs, e.g., half-precision input multiplied with 8-bits integer. Hardware accelerators, including GPUs, support a fixed set of data types, and thus, mixed-input matrix multiplication requires software transformations to map to the hardware operations. To that end, in this blog we focus on mapping mixed-input matrix multiplication onto the NVIDIA Ampere architecture. We present software techniques addressing data type conversion and layout conformance to map mixed-input matrix multiplication efficiently onto hardware-supported data types and layouts. Our results show that the overhead of additional work in software is minimal and enables performance close to the peak har

### AI overview

The article explains how IceRock uses wireframe and design prototypes during mobile app development. It argues that clickable prototypes communicate navigation, functionality, usability, and final behavior more effectively than screen maps, with fidelity varying according to client needs.

### Source excerpt

Businesses are always looking for ways to launch apps quickly and with minimal development costs. There are various ways to do this: sketch your app design, launch apps from scratch with frameworks, or use builders. Different situations call for different solutions. In this article, I will tell you about the approaches we use at IceRock. Our company specializes in outsource development of mobile apps, so we constantly look for new ways to speed up the development and enhance tried-and-true workflows. Why a Prototype is Better than a Screen Map Before we start the development, we prepare one or several prototypes of the future app. This is more efficient than going straight to design or starting to develop the app right away. A screen map is a set of images showing all app screens and their relationships. It visualizes the flow of the screens, but it doesn't allow you to get a feel for the result and understand how usable the interface will be. In other words, it is less illustrative. Clickable prototypes are more informative. We divide prototyping into two parts: we use a "wireframe prototype" before the design, and a "design prototype" after. A wireframe prototype is a schematic prototype that helps us understand the navigation and functionality aspects of an app. A design prototype is a product assembled once the UI design is complete. It is used to demonstrate the future app to the customer, for marketing purposes, and sometimes for testing. It also shows the developers how the final app is supposed to work. After the design, we make a clickable prototype. The level of detail in this prototype can vary according to the client's needs: it can be low-fidelity or high-fidelity. Low-fidelity prototypes consist of static images with active links to the next screens on the buttons. This is the type of prototype we used for the Snow4u project. High-fidelity prototypes are very similar to the app and fully interactive: you can type any text in the input fields, there are

### AI overview

This article explains why code readability matters in Kotlin, emphasizing that developers spend much more time reading code than writing it. It argues that fewer lines or characters do not necessarily make code easier to understand, and that readability depends on cognitive load and familiarity with programming idioms, especially for less experienced Kotlin developers.

### AI overview

This post examines counting objects that satisfy range and other filters when no database is available. It compares Java's Stream API with specialized Java code and finds that exploiting data already sorted by time can make filtering and counting more efficient.

### Source excerpt

This post follows on from my last post about selecting objects satisfying a range predicate, and instead looks at how to count the objects. If you can select objects, you can count them too, but it's a simpler problem so resources can be saved with a specialised solution.

### Source excerpt

A close friend recently said to me: I'm Copying You Since You're So Effective with respect to how much I tend to get done and I thought I'd elaborate on this a bit since I suspect that why I'm effective isn't always apparent. These aren't really in any order other than the order that I chose to finish them. I suspect they are all pretty important. Ten Reasons Why I Think I'm Effective Get Rid Of Anything That Pisses You Off. To the outside world, I'm a pretty chill person. I try very, very hard to never lose my cool and there's a reason for that - I have a bad temper. One of the things I learned early on about myself is that getting upset ruins my productivity. And so what I do is when I find that something pisses me off, I get rid of it - by fixing it. See my upcoming post on Url Soup for an example. Time is The Only Thing You Have So Do the Math on Everything. I'm a father, a husband and a technologist and I started my first company when I was 19 - and I've pretty much been busy since I was 19. This has always made me very, very aware of just how valuable anyone's time is. I don't waste my time and I hate, hate, hate anything that wastes my time. Just as an example, I used to loathe configuring new laptops. Setting up a new laptop, for a developer, is generally about a week long endeavor until I (or any developer I've ever watched) is really comfortable with it. If you assume that a laptop lasts a developer 3 years and you have 30 years left in your career, that's 10 weeks of your life. Once I did that math then I realized that my figuring out how to configure a laptop quickly and easily was seriously worthwhile and I did (and then I open sourced an example). Find People Smarter than You - And Copy Them. I'd love to tell you that it was my idea for how to configure a laptop automatically but it wasn't. I stole this, shamelessly, from Jeff Geerling; but I did (and do) credit him. One thing I learned early on is that when you don't know what you are doing, finding p

### AI overview

A personal account of effective daily Agile stand-up meetings for a team of eight. The recommended practices include starting on time regardless of attendance, scheduling meetings five minutes after the hour, using a consistent meeting URL, and following a simple three-question format.

### Source excerpt

So my new gig has moved to doing daily agile standup meetings and while I've done these before, I don't think I've ever seen them done quite so consistently well. And the credit for this goes to my boss, Dave Sifry, who is our lead facilitator. We are a team of 8 people and, so far, we have brought them in at under the scheduled 15 minutes per meeting every time. Here are the techniques that we are using: Start on time. If everyone isn't there, well, the meeting happens anyway. Ideally, if the team lead isn't on time, the meeting happens anyway. Scheduled for 5 minutes after the hour. This allows people in other meetings to make it. A consistent Url. This is the one down side to Zoom - the meeting can't start if the leader isn't present. If we used Google Meet then that wouldn't be an issue. A simple format. A ridiculously simple, fast format: Here's what I'm up to today Here's what I'm stuck on. How can I help anyone else? While I'm generally not a fan of meetings, agile stand ups, done this way, tend to bring developers into line. Even if a developer isn't good with email - or good with text messages - normally they can handle "show up at time X for 15 minutes every day". In closing, while I'm not a huge proponent of heavy weight agile processes (think scrum / agile velocity), I am really enjoying daily stand ups again. Recommended.

### AI overview

An article on Vim's historical development and effective use. It traces the editor's lineage from QED through ed, ex, and vi, and encourages readers to study Vim's core functionality, use plugins thoughtfully, and rely less on pre-packaged vimrc files.

### Source excerpt

2019-07-19 This article is based on historical research and on simply reading the Vim user manual cover to cover. Hopefully these notes will help you (re?)discover core functionality of the editor, so you can abandon pre-packaged vimrc files and use plugins more thoughtfully. To go beyond the topics in this blog post, I'd recommend getting a paper copy of the manual and a good pocket reference.

### AI overview

A product manager shares practical ways to use email for cross-functional communication and engagement. The article recommends including meeting notes and action items directly in emails, recirculating substantially revised documents, using personalized mail merge for feedback requests, and encouraging timely discussion on team emails. It presents the author's reported response-rate experiment while noting that the supplied text is incomplete.

### Source excerpt

I send way too many emails in a day. My inbox is very intermingled with my to do list and often represents some form of it. More relevant though is that email is a primary means of how I accomplish work. Being a PM I work cross functionally with other teams (from marketing, to engineering, to sales, to BD, to other product teams) and of course customers. Having to work so cross functionality I've found a lot of hacks I use to be able to better accomplish your goals with email, here is a collection of some of those. Let me be clear, this is not another post about inbox 0, how I swapped to slack. This instead is how I use email to more effectively communicate and get people to engage. In other words it is about making emails more useful, not just getting through them faster. And onto those tips. Don't leave a document in a document Often times I've found folks will collaborate in a document during a meeting or take notes there. After the meeting folks will email the document around, but few seldom actually open. Reasons may be they're not logged in on their phone or it may be they just don't care that much, I'm not really sure. What I do know is that by taking the notes and action items from the doc and including them in the email you will get more people paying attention to them. If you really want to get good at this when there is significant revisions of a work in progress document, re-circulate the updated version via email. Again not just a link to it, but the document itself. Mail merge isn't just for marketing Years ago I sent a company wide request for feedback (to about 120 people). I got less than 3 responses. I ran an experiment the next time I needed the same thing using a mail merge so my same email seemed personal and was from me to them instead of some large alias. I got a response rate of over 45%. Use this wisely... not every email you send needs a response. A broad update can absolutely be to team@, but when you need to get actual feedback and people d
