@hansfbaier Why not put the expansion SRAM on the base board rather than breaking it out to a header?

This is how the upcoming revision of the #MiSTeX #FPGA #retrogaming console will look like.

@scientistswrite I would like to add: Writing a paper in the spaces between "real work". Writing is a full time job, it requires focus and energy to bring your thoughts together coherently. In this way it is also very rewarding because you have to spend time thinking.

As an academic writing coach, here are the 9 mistakes I see PhD and grad students make when writing scientific papers. A thread. 🧵

Let’s be fair here. I think we should all be able to agree on the following: 1) The trend of “journal article as press release” in our field has to stop. If it’s a press release, just put out a PR. 2) If you go against the (long-time) norms of our field (not posting on the arXiv concurrent with journal submission), you are attempting to game the system and will likely and rightly get burned. 3) The journal / peer review / referee system is fundamentally broken. @Nature holds significant blame here. Nature and other “elite” journals should take note: publications in your journal are starting to be negatively correlated with actually scientific impact. Referee reports are often worthless/ignorant or ignored. I feel it is necessary to say all this because the core of the IBM paper had some great results! (100 qubits in 60 time steps and evidence of better to come.) It should be celebrated. The physics story salesmanship was unnecessary. It is we as referees, collaborators, readers, communicators, program managers, and hiring committees, that must reset the scientific integrity of our field. There is no need for hype and creating stories to justify what is already some great work.

A radio-frequency multiplier implemented in a multigate silicon nanowire transistor at cryogenic temperatures greatly alleviates the challenges associated with the delivery of high-frequency signals to semiconductor quantum processors. @quantum_motion go.aps.org/3JokJdc

@TICS_Game I have since learned that this chip is SunPlus SPL132A 512 kB CPU + LCD Controller!

Looking for motivated and curious minds to join me, @magneticlemur (@MQSciEng ), and Jarryd Pla (@UNSWEngineering) on 4yrs theory+exp PhD to develop hybrid quantum devices with @SydneyQuantum funding! check out details at sydneyquantum.org/discover/quant… and DM me for details/contact

@SimoneRoncallo A quantum particle arrives precisely when it means to.

🕥 When does a particle arrive at a detector? There is no easy answer in quantum mechanics, for which time is not an observable. This question raises the so-called time of arrival problem. 🧵 doi.org/10.22331/q-202…

@dangolding @guckhq @afterclimate This makes it sound like they are actively producing power rather what they actually did which is reducing power. If fortnite shut down its servers they could 'create' many more wind farms!

This is actually incredible from ⁦@afterclimate⁩ : “Fortnite basically built the equivalent of a small wind farm with software. And they did it, more or less, without anyone even noticing.” gameshub.com/news/education…

@hansfbaier Is there a major benefit using an Artix-7 100T over the Cyclone V?

New Toys! These will power the MiSTeX MiSTer replacement.

Giveaway time! As promised One sealed copy of Metroid Prime Remastered for the Nintendo Switch could be yours. Just follow me and retweet this and I’ll draw a random winner on March 17. Anywhere in the world, ill cover shipping. Good luck ! #contest #MetroidPrimeRemastered

@hansfbaier Love the project, looking forward to seeing more!

@hansfbaier Have you finalised the name? It would be nice to pick something new, not MiST*, for the future of FPGA emulation

Took me about a week to divorce the MiSTer from the Cyclone V HPS system, and run the Linux part on an Allwinner D1 instead.

@MJBiercuk Can you decline invitations?

Does anyone else's #quantum #conference /#speaking calendar look like a continuous block of time on travel for the next 4 months?!? #toomanyconferences

@culturaltutor A lot of this history (and more) is covered in the Architecture of Happiness by Alain de Botton, for anyone else looking for an accessible read on these different schools of thought.

Skyscrapers used to be Art Deco and neo-Gothic, so what happened?

@quantum_graeme What is the definition of expert that people use here? I would say I know the gist of many topics in my field, but would *maybe* only call myself an expert on a small subset of those. Am I setting the bar too high? Surely no one has detailed knowledge of all topics in their field

@samdhodges @PhDVoice @PostdocVoice @AcademicChatter Needs an option "Only when it's irrelevant". I'll always be Dr Johnson when signing up to a gym.

@FinitePhysicist I only use loops to copy and paste my code N times.

loops in programming are kind of pointless when copy&paste already exists and works just fine?

@InternetHippo Take it sleazy!
