Show HN: Hacker News Blogroll https://ift.tt/gtqbPJS

Show HN: Hacker News Blogroll This was submitted about 9 months ago as a Show HN ( https://ift.tt/xRZ9Cnb ), people was generally favorable to it, but I never got around to do anything else with it past the first few days. I recently rescued a Github account I had, so I'm putting the source of the Rails app over there in case anyone wanted to do anything with it. The site still runs on https://dm.hn Generates about 2 to 3 GB bandwidth usage every month, and the blogs are still checked every day for new content. I must say, I still visit every week and find interesting entries to read. https://ift.tt/xp7arVW April 11, 2024 at 01:04AM

Show HN: Visualize eBay laptops in bulk with laptopscout https://ift.tt/CgbZpBV

Show HN: Visualize eBay laptops in bulk with laptopscout A bit late in the new diskprices-like website trend, but here's my contribution to the ecosystem. The goal here is to get an instant comparison of the laptops on ebay, using mostly 3 metrics of now: CPU benchmark rank, GPU benchmark rank, and price, without having to scroll through the item description or google the PC model. At the moment there are some parsing bugs, and some components that aren't parsed yet. I also quickly run into the ebay rate limit, making it hard to maintain an hour-by-hour listing. Curious to know what you guys think! https://laptopscout.xyz/EBAY_US April 10, 2024 at 02:04AM

Our Vision Goes Beyond Zero

Our Vision Goes Beyond Zero
By Amanda Eaken

Ten years ago last month, San Francisco proudly became the second city in the United States to adopt Vision Zero, an ambitious pledge to end all serious and fatal traffic crashes. Since I joined the SFMTA Board of Directors in 2018, I have been laser focused on what it will take to get to zero.

Like many of you, I feel very strongly that this must be a top priority for our city. I see the ability to walk, bike, drive, scoot, roll or take transit safely, without fear of harm, as a basic right and freedom that people should expect in our city. A basic right just like turning on the tap and expecting that the water is safe for you to drink — something you just assume the government will take care of for you. And, as I affirmed at the Mayor’s Vision Zero press conference, I share in the feelings of rage, powerlessness and grief whenever I learn that anyone is injured or killed in traffic violence on our streets.

But it wasn’t until recently, at the SFMTA Board workshop in January, that I realized that Vision Zero is not, actually, our vision. Of course no one should die or be injured in traffic on our streets. Great cities are for people, not cars. But we could reach Vision Zero and still fall far short of the city I think we want to be.

Let me unpack this a bit further. I think safety is actually the floor, it’s the minimum. Safety should be a basic right of people trying to get around the city. But as we’ve seen on Slow Sanchez Street or the Great Highway over the last few years, streets can be so much more than just safe. They can be places that uplift and elevate people. I know on some of my toughest days, a walk on JFK Promenade is pure therapy. More often than not these days I run into someone I know out there, and it warms my heart to see so many people enjoying themselves. I love seeing the irrepressible smiles on parents’ faces as they teach their very small family members to safely ride a bicycle, or hearing friends laughing as they lounge in the yellow Adirondack chairs.

Our streets can be blank canvases for local artists, places for communities to express and celebrate their unique identities and histories. As a member of the NOPA community, I recently learned that the San Francisco Parks Alliance is going to bring art to some of our neighborhood Slow Streets. I was asked to fill out a survey about which elements of our community’s history best express our identity, and should be featured in the artwork. I highlighted the Black churches in our neighborhood, NOPA Corner Market, the Panhandle, the University of San Francisco and Divisadero Street.

Great streets should, in my view, create opportunities for joy and delight. Streets can be places that enable play and silliness like the ping pong table at 8th Avenue or the white wobbly chairs kids love to spin around in. They can be community gathering spaces that help to create the spontaneous moments of connection that are why we all live in a city to begin with.

Whenever I ride my bike down JFK promenade on a Sunday and hear the community sing-along around that wonderful old and warped Rec and Park piano, or stroll down Great Highway, take a seat on one of those orange metal chairs and soak in some live jazz with the spectacular Pacific Ocean behind me, I am so moved. This, I think to myself, THIS is the kind of city I want to live in – where the government partners with communities to create wonderful spaces that provide more opportunities for joy and connection.

COVID changed all of our lives, for some of us permanently. I observe — and have experienced — that some of us are still quite isolated, that people are craving more connection. Streets can be places for community members to come together, to combat what our Surgeon General is calling a national epidemic of loneliness.

So as we look to the next ten years of the essential work of making our streets safe, what some are calling Vision Zero 2.0, I want us to pause and ask ourselves whether Vision Zero is the extent of our vision. Vision Zero means nothing tragic or unacceptable happens. But I want to flip that around. Because every day, in thousands of ways, big and small, I hope our streets can do more than just prevent tragedies. I hope our streets can be places people can experience moments of joy and delight on their commutes. Where they can cross the street with comfort and dignity, rather than feeling that they have no option but to become defensive, anxious pedestrians, constantly on the lookout for cars turning right on red creeping into the crosswalk or drivers looking down at their phones rolling through a stop sign. I want our city to be a place that is safe for children to travel independently. When we make these important policy decisions about whether to restrict certain movements of vehicles, I want us to think about our kids — it’s their city too.

So please: join me in both recommitting to and re-envisioning Vision Zero over these next months.

I created the Vision Zero subcommittee of the SFMTA Board of Directors because I wanted us to have a space where we can sit around a table together, to share ideas, to jointly problem-solve, to co-create the city we all want to live in. Bring your vision, passion, creative thinking, as we embark on the journey to chart a course for the next ten years.

The next meeting is Tuesday June 11th at 1 p.m. at 1 South Van Ness Avenue, or you can always attend my virtual office hours on Mondays at 4 p.m. during the first and third weeks of the month.

Amanda Eaken is the Chair of the SFMTA Board of Directors which provides policy oversight for the safe and efficient movement of people and goods in San Francisco in accordance with the San Francisco Charter and the Transit-First Policy. This includes the San Francisco Municipal Railway (Muni), automobiles and trucks, taxis, bicycling and walking. The SFMTA Board of Directors also serves as members of the San Francisco Parking Authority. The SFMTA Board of Directors generally meets on the first and third Tuesday of each month at 1:00 pm. in Room 400, City Hall unless otherwise noted. Members of the public can attend or view meetings on SFGovTV2.

Show HN: The fastest way to run Mixtral 8x7B on Apple Silicon Macs https://ift.tt/BEuvIQA

Show HN: The fastest way to run Mixtral 8x7B on Apple Silicon Macs I’d originally launched my app: Private LLM[1][2] on HN around 10 months ago, with a single RedPajama Chat 3B model. The app has come a long way since then. About a month ago, I added support for 4-bit OmniQuant quantized Mixtral 8x7B Instruct model, and it seems to outperform Q4 models at inference speed and Q8 models at text generation quality, while consuming only about 24GB of RAM[3] at 8k context length. The trick is: a) to use a better quantization algorithm and b) to use unquantized embeddings and the MoE gates (the overhead is quite small). Other notable features include many more downloadable models, support for App Intents (Siri, Apple Shortcuts), on-device grammar correction, summarization etc with macOS services and an iOS version (universal app), also with many smaller downloadable models and support for App Intents. There's a small community of users building and sharing LLM based shortcuts on the App's discord. Last week, I also shipped support for the bilingual Yi-34B Chat model, which consumes ~18GB of RAM. iOS users and users with low memory Macs can download the related Yi-6B Chat model. Unlike most popular offline LLM apps out there, this app uses mlc-llm for inference and not llama.cpp. Also, all models in the app are quantized with OmniQuant[4] quantization and not RTN quantization.

Show HN: Dimity Jones in Puzzle Castle: An Electronic Escape Novel https://ift.tt/420GiPU

Show HN: Dimity Jones in Puzzle Castle: An Electronic Escape Novel _Dimity Jones In Puzzle Castle: An Electronic Escape Novel in Eighty-Nine Ciphertexts_ is a (mostly) fictional story, contained in a single text file, that requires the reader to solve puzzles as they go along, and to use each chapter's solution as a key to decipher the next. Think: escape room in the form of a novel. A computer, and rudimentary coding skills in a language of your choice, will be indispensable for performing the transformations -- and might help with the solving too! My wife, the author, passed away five years ago. This is not the last thing she wrote, but it is the most unusual, unapproachable, and personal of her major works. It is also, as the only novel of hers that I cannot breeze through in an afternoon (and despite my unflattering appearance in it), my favorite. Though _Dimity Jones_ was left unfinished, and perhaps abandoned, at the time of my wife's death, its elements were all there, on her hard disk, awaiting only a final compiling. My contribution to this text has therefore been little more than that of an occasional copyeditor (my wife was a meticulous speller and self-proofreader) and playtester. Before releasing this work more widely, I would love to have it test-driven by better coders and puzzlers than I. Any and all feedback is welcome, from positive to negative, from the sweeping to the picayune. Let me know what confuses or frustrates you -- and especially let me know if (where) you get stuck. Otherwise, there are no special instructions; it's all in the book. While _Dimity Jones_ is still in its debugging/proofreading phase, please refrain from sharing it or putting it any (other) public place. (Christine would have been horrified to see her work thus published before it was letter-perfect; but I have exhausted my pool of friends and colleagues both able and willing to tinker with it. This seems like the ideal community of potential testers.) Thanking you in advance. I hope you enjoy! https://ift.tt/FRYkBdl April 9, 2024 at 12:17AM
