Some Cool stuff out there.

The local "classic Audio" emporium has quite a selection of amps there.

There are no fewer than 10 Crown Amps including d150s and d75s and two d300s. Must have stripped a recording studio. Crowns are full steel toe certified professional units. Even golden ears years ago had to give them their due.

Also a few Bryston and a Classe for around a kilobuck. Bryston 4bs go for 900 to 1300 depending on the vintage. 3Bs are about 30% less at half the Watts. Two excellent Canadian brands.

There are also a smattering of Japanese beasts. A Nikko and a couple Pioneers are there. Big companies can do it too.

What actually caught my attention had already sold or at least was laid away. It was a Pioneer compander. For those unfamiliar they are devices that either compress or expand the dynamic range of a recording. Often they do both with a twist of a knob in the correct direction. I once had such and actually sold them years ago at this same shop. They were DBX brand.

Oooh they have dbx too under miscellaneous.

They are interesting and can improve a shitty recording if it has been over compressed. I even have a DBX encoded LP that needs a processor to make it sound anything but shit. I could use one for that Carly Simon LP I bought as it is way too compressed.

What these things do is vary the gain by the incoming volume. An expander increases the gain as the volume increases, and compressor does the opposite. Many studios and mastering shops cheat on recordings using these things. Compressed tracks may sound better in a car or in a place with lots of noise like a club. There are no audiophile level machines. ICs and Opamps abound.

When I had them (two actually) I was naive as to the utility but they had some cool flashing lights.

The dbxii was for the LP decoding and my Reel to Reel tape machine. The 3BX was for the whole system. I also had a DBX subharmonic Bass synthesizer which was not bad. That was before my franken amp and my tube amps needed help.

I am glad I grew out of that phase.

On Craigslist there are not one but Two ARC Tube amps! One is 100 Watts per side and the other 60 Watts. Each were 2700ish bucks. If I won the lottery I would be tempted just for nostalgia's sake. They have a particular voice, but I like it. That is still a lot of glass.

Bluetooth Technology

What Is Bluetooth Technology?

Bluetooth is a wireless technology standard. It is utilized for trading information among fixed and cell phones over brief distances utilizing short-frequency super high recurrence (UHF) radio waves.

All the more explicitly, Bluetooth utilizes the microwave radio recurrence range in the 2.402 GHz to 2.480 GHz reach to send advanced information remotely.

Bluetooth innovation is a profoundly mind boggling subject and we might be starting to expose what's underneath in this article. In the event that you'd prefer to find out about Bluetooth innovation in more prominent detail.

The intricacy of Bluetooth innovation is expected, partially, to its staggeringly wide scope of utilizations. Not exclusively is Bluetooth used to communicate computerized sound from advanced gadgets to speakers however it is additionally executed in the accompanying remote information moving applications:

Contol and correspondence among cell phones and other Bluetooth sound gadgets and Bluetooth-viable vehicle sound frameworks.

Correspondence between a cell phone and a brilliant lock for opening entryways.

Correspondence among cell phones and other Bluetooth sound gadgets and Bluetooth-viable remote speakers.

Correspondence between remote Bluetooth headsets and radios/gaming frameworks/PCs, and so on

Spilling of information from Bluetooth-empowered wellness gadgets to cell phones/PCs and so on

Remote systems administration between PCs in nearness.

Correspondence among PCs and their information/yield gadgets.

Item EXchange move of documents, contacts, schedules/timetables and updates.

Correspondences in test gear, GPS beneficiaries, clinical hardware, standardized tag scanners, and traffic light gadgets.

As a swap for infrared remote and wired RS-232.

Sending notices from Bluetooth-empowered promoting hoardings to discoverable Bluetooth gadgets.

Crossing over between two Industrial Ethernet organizations.

Interfacing remote regulators and different accomplices to gaming consoles.

Dial-up web access utilizing information fit Bluetooth-viable cell phones as remote modems.

Short-range transmission of wellbeing sensor information from clinical gadgets to cell phones and committed telehealth gadgets.

Permitting Digital improved cordless telecom (DECT) telephones ring and answer approaches benefit of Bluetooth-skilled cell phone.

Ongoing area frameworks (RTLS) used to follow and recognize the area of items progressively.

Individual security application on cell phones for the counteraction of robbery or loss of things.

Expectation of movement times and street clog for drivers.

Association between movement regulators in augmented experience (VR) and PC.

Bluetooth Versions

In spite of the fact that initially created in 1989, the primary cycle (adaptation 1.0) of Bluetooth just came to fruition in 1999 after the Bluetooth Special Interest Group, the overseeing body, was framed in 1998.

The Bluetooth Special Interest Group keeps on enhancing the norm and deliveries new forms occasionally. With each new form, the BSIG enhances three key components (territory, information speed and force utilization) alongside whatever fringe factors they see fit for development.

Each form of Bluetooth upholds descending similarity. This implies that the most recent standard will work with every single more established adaptation. The capacities of a Bluetooth association will be restricted to the norm of the gadget with the most seasoned rendition of BT.

In other words, a speaker with Bluetooth 5.0 will turn out entirely great with a Bluetooth 4.2 sound gadget. Nonetheless, the association might be on par with the constraints of the 4.2 norm.

How Do Bluetooth Speakers Work?

Bluetooth speakers work actually like commonplace wired speakers with the exception of the manner by which they get sound signs.

Wired inactive speakers get their speaker level sound signs by means of designed speaker links. Wired dynamic speakers may get speaker level sign through speaker link or line, mic and instrument level signs through more slender sound link.

Bluetooth speakers, as their name recommends, get their sound signals remotely by means of Bluetooth.

As a matter of fact, to be more exact, the implicit force intensifier of the Bluetooth speaker will get the sound sign remote by means of Bluetooth.

For what it's worth, Bluetooth conventions will convey regular line level signs easily. This degree of sign, as in wired arrangements, requires enhancement from a force amp before it can appropriately drive the driver(s) of an amplifier.

To work appropriately with a sound gadget, a Bluetooth speaker should be matched (remotely associated) with the Bluetooth sound gadget. We'll examine how to match Bluetooth speakers to different gadgets in the segment named How To Connect (Pair) Bluetooth Speakers To Bluetooth Audio Devices.

When matched, the speakers and computerized sound gadget structure a Piconet where the sound gadget may viably convey its sound message to the speaker by means of Bluetooth.

Note that keen speakers with voice partner technology and delay/play controls will likewise send data back to the sound gadget through the Piconet.

When the computerized sound sign is gotten by the speaker's Bluetooth beneficiary, it should go through two key segments before it can drive the speaker's drivers.

To begin with, on the grounds that Bluetooth communicates computerized sound, the got sound sign should be changed over into a simple sound sign. This is done through an inherent advanced to-simple converter.

Then, as we've recently talked about, the changed over simple sound is sent through a force intensifier. The enhanced yield sign will have low sufficient impedance and sufficiently high flow to appropriately drive the speaker driver(s).

When the sign is gone through the driver, it is the driver's responsibility to deliver sound waves that address the sound sign. This is the way we hear the data of a sound sign by means of Bluetooth speakers.

In the event that you've skirted or need to re-read this current article's introduction on how speaker work, click here.

Before we dive into the subtleties of how sound is sent through Bluetooth, we should have a more extensive glance at how sound is communicated from the advanced sound gadget to the Bluetooth speaker and how the sound is then changed over into sound waves for the audience to hear.

The sign stream from a Bluetooth sound gadget to a matched Bluetooth speaker to the audience's ears is as per the following:

The Bluetooth-skilled sound gadget plays a computerized sound sign.

This sound sign is encoded by a codec (regularly SBC "Low Complexity Subband Code," which is upheld by all gadgets) in the A2DP move standard.

This encoded sound sign is utilized as the tweaking signal that adjusts the Bluetooth UHF radio transporter signals.

The radio transporter waves are communicated remotely according to Bluetooth principles between the sound gadget's BT transmitter and the Bluetooth speaker's BT recipient.

The Bluetooth collector at that point disentangles the balance signal from the transporter wave.

The A2DP encoded signal is then additionally decoded back to the planned computerized sound sign (pressure misfortunes apply when encoding and translating the sign).

This advanced sound sign is then changed over into a simple configuration by the speaker's implicit computerized to-simple converter (DAC).

The simple sound is then intensified by an inherent enhancer circuit.

This intensified sound sign is then shipped off the speaker drivers (note that, for sound system and encompass codecs, the sound signs will be part now to drive their particular drivers).

The drivers their simple sound signal(s) into sound waves.

The listener(s) hear the sound waves.

That is a remarkable sign stream for an technology that is so easy to use. That is important for the excellence of Bluetooth speakers and Bluetooth technology as a rule: the designers and innovators deal with the intricacies and we can utilize the technology without intuition too profoundly about it.

That being said, it's acceptable to have a thought of how sound is sent by means of Bluetooth technology to all the more likely comprehend Bluetooth speakers.

Version 422

youtube

windows

zip

exe

macOS

app

linux

tar.gz

🎉🎉 It was hydrus's birthday this week! 🎉🎉

I had a great week. I mostly fixed bugs and improved quality of life.

tags

It looks like when I optimised tag autocomplete around v419, I accidentally broke the advanced 'character:*'-style lookups (which you can enable under tags->manage tag display and search. I regret this is not the first time these clever queries have been broken by accident. I have fixed them this week and added several sets of unit tests to ensure I do not repeat this mistake.

These expansive searches should also work faster, cancel faster, and there are a few new neat cache optimisations to check when an expensive search's results for 'char' or 'character:' can quickly provide results for a later 'character:samus'. Overall, these queries should be a bit better all around. Let me know if you have any more trouble.

The single-tag right-click menu now always shows sibling and parent data, and for all services. Each service stacks siblings/parents into tall submenus, but the tall menu feels better to me than nested, so we'll see how that works out IRL. You can click any sibling or parent to copy to clipboard, so I have retired the 'copy' menu's older and simpler 'siblings' submenu.

misc

Some websites have a 'redirect' optimisation where if a gallery page has only one file, it moves you straight to the post page for that file. This has been a problem for hydrus for some time, and particularly affected users who were doing md5: queries on certain sites, but I believe the downloader engine can now handle it correctly, forwarding the redirect URL to the file queue. This is working on some slightly shakey tech that I want to improve more in future, but let me know how you get on with it.

The UPnPc executables (miniupnp, here https://miniupnp.tuxfamily.org/) are no longer bundled in the 'bin' directory. These files were a common cause of anti-virus false positives every few months, and are only used by a few advanced users to set up servers and hit network->data->manage upnp, so I have decided that new users will have to install it themselves going forward. Trying to perform a UPnP operation when the exe cannot be found now gives a popup message talking about the situation and pointing to the new readme in the bin directory.

After working with a user, it seems that some clients may not have certain indices that speed up sibling and parent lookups. I am not totally sure if this was due to hard drive damage or broken update logic, but the database now looks for and heals this problem on every boot.

parsing (advanced)

String converters can now encode or decode by 'unicode escape characters' ('\u0394'-to-'Δ') and 'html entities' ('&'-to-'&'). Also, when you tell a json formula to fetch 'json' rather than 'string', it no longer escapes unicode.

The hydrus downloader system no longer needs the borked 'bytes' decode for a 'file hash' content parser! These content parsers now have a 'hex'/'base64' dropdown in their UI, and you just deliver that string. This ugly situation was a legacy artifact of python2, now finally cleared up. Existing string converters now treat 'hex' or 'base64' decode steps as a no-op, and existing 'file hash' content parsers should update correctly to 'hex' or 'base64' based on what their string converters were doing previously. The help is updated to reflect this. hex/base64 encodes are still in as they are used for file lookup script hash initialisation, but they will likely get similar treatment in future.

birthday

🎉🎉🎉🎉🎉

On December 14th, 2011, the first non-experimental beta of hydrus was released. This week marks nine years. It has been a lot of work and a lot of fun.

Looking back on 2020, we converted a regularly buggy and crashy new Qt build to something much faster and nicer than we ever had with wx. Along with that came mpv and smooth video and finally audio playing out of the client. The PTR grew to a billion mappings(!), and with that came many rounds of database optimisation, speeding up many complicated tag and file searches. You can now save and load those searches, and most recently, search predicates are now editable in-place. Siblings and parents were updated to completely undoable virtual systems, resulting in much faster boot time and thumbnail load and greatly improved tag relationship logic. Subscriptions were broken into smaller objects, meaning they load and edit much faster, and several CPU-heavy routines no longer interrupt or judder browsing. And the Client API expanded to allow browsing applications and easier login solutions for difficult sites.

There are still a couple thousand things I would like to do, so I hope to keep going into 2021. I deeply appreciate the feedback, help, and support over the years. Thank you!

If you would like to further support my work and are in a position to do so, my simple no-reward Patreon is here: https://www.patreon.com/hydrus_dev

full list

advanced tags:

fixed the search code for various 'total' autocomplete searches like '*' and 'namespace:*', which were broken around v419's optimised regular tag lookups. these search types also have a round of their own search optimisations and improved cancel latency. I am sorry for the trouble here

expanded the database autocomplete fetch unit tests to handle these total lookups so I do not accidentally kill them due to typo/ignorance again

updated the autocomplete result cache object to consult a search's advanced search options (as under _tags->manage tag display and search_) to test whether a search cache for 'char' or 'character:' is able to serve results for a later 'character:samus' input

optimised file and tag search code for cases where someone might somehow sneak an unoptimised raw '*:subtag' or 'namespace:*' search text in

updated and expanded the autocomplete result cache unit tests to handle the new tested options and the various 'total' tests, so they aren't disabled by accident again

cancelling a autocomplete query with a gigantic number of results should now cancel much quicker when you have a lot of siblings

the single-tag right-click menu now shows siblings and parents info for every service, and will work on taglists in the 'all known tags' domain. clicking on any item will copy it to clipboard. this might result in megatall submenus, but we'll see. tall seems easier to use than nested per-service for now

the more primitive 'siblings' submenu on the taglist 'copy' right-click menu is now removed

right-click should no longer raise an error on esoteric taglists (such as tag filters and namespace colours). you might get some funky copy strings, which is sort of fun too

the copy string for the special namespace predicate ('namespace:*anything*') is now 'namespace:*', making it easier to copy/paste this across pages

misc:

the thumbnail right-click 'copy/open known urls by url class' commands now exclude those urls that match a more specific url class (e.g. /post/123456 vs /post/123456/image.jpg)

miniupnpc is no longer bundled in the official builds. this executable is only used by a few advanced users and was a regular cause of anti-virus false positives, so I have decided new users will have to install it manually going forward.

the client now looks for miniupnpc in more places, including the system path. when missing, its error popups have better explanation, pointing users to a new readme in the bin directory

UPnP errors now have more explanation for 'No IGD UPnP Device' errortext

the database's boot-repair function now ensures indices are created for: non-sha256 hashes, sibling and parent lookups, storage tag cache, and display tag cache. some users may be missing indices here for unknown update logic or hard drive damage reasons, and this should speed them right back up. the boot-repair function now broadcasts 'checking database for faults' to the splash, which you will see if it needs some time to work

the duplicates page once again correctly updates the potential pairs count in the 'filter' tab when potential search finishes or filtering finishes

added the --boot_debug launch switch, which for now prints additional splash screen texts to the log

the global pixmaps object is no longer initialised in client model boot, but now on first request

fixed type of --db_synchronous_override launch parameter, which was throwing type errors

updated the client file readwrite lock logic and brushed up its unit tests

improved the error when the client database is asked for the id of an invalid tag that collapses to zero characters

the qss stylesheet directory is now mapped to the static dir in a way that will follow static directory redirects

downloaders and parsing (advanced):

started on better network redirection tech. if a post or gallery URL is 3XX redirected, hydrus now recognises this, and if the redirected url is the same type and parseable, the new url and parser are swapped in. if a gallery url is redirected to a non-gallery url, it will create a new file import object for that URL and say so in its gallery log note. this tentatively solves the 'booru redirects one-file gallery pages to post url' problem, but the whole thing is held together by prayer. I now have a plan to rejigger my pipelines to deal with this situation better, ultimately I will likely expose and log all redirects so we can always see better what is going on behind the scenes

added 'unicode escape characters' and 'html entities' string converter encode/decode types. the former does '\u0394'-to-'Δ', and the latter does '&'-to-'&'

improved my string converter unit tests and added the above to them

in the parsing system, decoding from 'hex' or 'base64' is no longer needed for a 'file hash' content type. these string conversions are now no-ops and can be deleted. they converted to a non-string type, an artifact of the old way python 2 used to handle unicode, and were a sore thumb for a long time in the python 3 parsing system. 'file hash' content types now have a 'hex'/'base64' dropdown, and do decoding to raw bytes at a layer above string parsing. on update, existing file hash content parsers will default to hex and attempt to figure out if they were a base64 (however if the hex fails, base64 will be attempted as well anyway, so it is not critically important here if this update detection is imperfect). the 'hex' and 'base64' _encode_ types remain as they are still used in file lookup script hash initialisation, but they will likely be replaced similarly in future. hex or base64 conversion will return in a purely string-based form as technically needed in future

updated the make-a-downloader help and some screenshots regarding the new hash decoding

when the json parsing formula is told to get the 'json' of a parsed node, this no longer encodes unicode with escape characters (\u0394 etc...)

duplicating or importing nested gallery url generators now refreshes all internal reference ids, which should reduce the liklihood of accidentally linking with related but differently named existing GUGs

importing GUGs or NGUGs through Lain easy import does the same, ensuring the new objects 'seem' fresh to a client and should not incorrectly link up with renamed versions of related NGUGs or GUGs

added unit tests for hex and base64 string converter encoding

next week

Last week of the year. I could not find time to do the network updates I wanted to this week, so that would be nice. Otherwise I will try and clean and fix little things before my week off over Christmas. The 'big thing to work on next' poll will go up next week with the 423 release posts.

This simplifies the administration of the app and additional functions can be added (e.g. auto storage and reservation). Added are the effect of changing the tempo, the speed, the sound of the playback, the effect of the inverse sound playback. Sound can be played when the video is played back faster and inversely. Filters, decoders and encoders have been optimized. Many codecs like H264 now work at least 50% faster. You can create DVDs and then write them to your hard drive using the recording utilities. This means that digital video, audio and command signals (in HDV, DVCAM and DV) can be transferred to a compatible video recorder or to a non-linear editing device using just one cable. All common video, audio and image formats are supported by OpenShot without any problems, and the all-rounder can even handle GIF files. In addition to numerous other resolutions, video projects are possible up to a 4K resolution with a maximum frame rate of 60 frames per second.

Binary Deconstruction is an immersive art installation by Calin Segal that examines the intricate interplay between personal data, tangible artifacts, and the immersive domain of extended realities. 1685968310541 Born out of a simple inquiry, Binary Deconstruction offers a reflective exploration of the possible impact that the mechanisms of encoding and decoding information have on our cognitive patterns, and on our ability to think abstractly. Visitors are encouraged to interact with a robotic device that scans their biometric data, including height, eye colour, face geometry, and temperature. The device then converts these data into a unique sculptural object that represents their physical identity at a particular moment in their lives. Throughout the process, participants have the opportunity to witness the transformation of their data into aesthetic properties, such as volume and composition, which serve as the blueprint for their personalized sculpture. Accompanying the physical installation is a virtual reality world that takes participants on an immersive and interactive journey, filled with scattered memories and fragmented imagery. This digital experience creates a space for personal interpretation and introspection, allowing the participant to engage with a generated totem – their personalized sculpture – in their own unique way. The journey culminates with the unveiling of this totem, providing a different way to experience the object. Binary Deconstruction encourages reflection and dialogue on the role of technology in creative production and addresses the ethical implications of using personal data in art. The installation invites visitors to contemplate the multifaceted nature of data in our ever-evolving world. Emphasizing a human-centered approach to technology, the interactive experience explores alternative formats for data storage that bridge the gap between the physical and digital form. https://ift.tt/Pgf0LcD This project was developed at V2_Lab for the Unstable Media as part of the Realities In Transition residencies, 2023. Credits Realities in Transition is co-funded by the European Union. This project aims to explore and support “alternative” XR creation and to experiment and promote new narratives and creative processes.

Blockchain Benefits For Fortune 500 Companies

Peer-to-peer sharing. P2P sharing ensures that no data is passed through a single channel. The information is passed through the millions of nodes in the network while using the two unique keys of both the sender and receiver. There is no middle man in blockchain transactions, which is usually the weakest link of any informational exchange. This way, the process is 10 times as secure and much faster.

• Decentralization. Hackers love sensitive data being stored in one place. That makes it easy to target and sets a clear target for them. Blockchain technology breaks information into pieces and spreads it all over its network, and each node stores chunks of information. If a separate node gets corrupted, there wouldn't be a dangerous data leak.

• Encryption and validation. Cybersecurity relies mostly on encryption and validation. All data stored in a blockchain is both encrypted and encoded upon storage. Users can decode the received information with the use of their personal key or a set of keys. Files are also validated with the help of signatures and records, making sure nothing has been altered during the process of receipt.

• Blockchain can be private. Blockchain technology can be both private and public. Limiting access to a blockchain project would greatly increase the security of a network, as it eliminates the majority of the threats. Although private networks have much fewer nodes, they are greatly more secure, and that is the reason why Fortune 500 companies use them. The reason for that is that nobody outside of the network can access it, which eliminates the chance of decoding even singular nodes.

• No DDoS. Blockchain is the single viable solution for the handling of DDoS attacks. This is one of the top reasons why successful companies go for decentralized technology as a form of cybersecurity

RTX A5000 and RTX A4000, but not only: Nvidia Ampere invades the professional world

RTX A5000 and RTX A4000, but not only: Nvidia Ampere invades the professional world Nvidia announced a series of new products professional architecture-based Ampere. For the desktop workstation sector, here are the solutions RTX A5000 e RTX A4000, two profoundly different cards following the RTX A6000 unveiled last October. On board of RTX A5000 we find a GA102 GPU - 8192 CUDA core, 256 Tensor core and 64 RT core - flanked by 24 GB of GDDR6 memory at 16 Gbps on 384-bit bus. The TDP is 230W. The card therefore has 2560 fewer CUDA cores than the RTX A6000 and half the video memory, even if the bandwidth is the same, equal to 768 GB / s. The FP32 computing power is equal to 27.8 TFLOPs, less than the 38.7 TFLOPs of the older sister. Nvidia RTX A5000 The RTX A4000 instead it is based on a GA104 GPU with 6144 active CUDA cores (192 Tensor core e 48 RT core) e 16 GB of GDDR6 memory on a 256-bit bus, for a bandwidth of 448 GB / s. The TDP is 140W. FP32 computing power settles at 19.2 TFLOPs. Both models have a PCI Express 4.0 x16 connection interface, but only RTX A5000 supports NVLink (for parallel connection with another RTX A5000) and, in addition to GPU passthrough, Single Root Input / Output Virtualization (SR-IOV) functionality. Nvidia RTX A4000 For the new RTX A5000 Nvidia has opted for a dual-slot cooling system, while the RTX A4000 takes up one slot. They both have four DisplayPort 1.4 and will be available later this month at undisclosed prices. The US company has also thought about workstation mobile con four new GPUs calls RTX A2000, A3000, A4000 and A5000 arriving in the second quarter. The first model is based on a GA106 GPU with 2560 active CUDA cores, 80 Tensor cores and 20 RT cores, while the A3000 e A4000 they adopt a chip GA104. In the case of the RTX A3000 we have 4096 CUDA cores, while in that of the RTX A4000 we find 5120 CUDA cores. Finally, the RTX A5000 mobile is based on a GA102 GPU with 6144 CUDA cores, therefore a decidedly neutered version with respect to the potential of the chip. The "old" Turing architecture finds its place in a sea of Amps with T1200 and T600, two graphics chips always dedicated to mobile workstations but low-end, in fact the chips have respectively 1024 and 896 CUDA cores for a power of 3.7 and 2.5 TFLOPs in combination with 4 GB of GDDR6 memory on 128 bit bus ( for a bandwidth of 160 and 192 GB / s respectively). This is Turing GPU without RT and Tensor core, such as those seen in the GeForce GTX 1600 range last year. The TDP is 35-95W for the T1200 depending on the configuration chosen by the OEM, while in the case of the T600 we are talking about 25W. Nvidia A30 For the datacenter world, here is Nvidia A30, A16 e A10, which are added to an offer that already includes the A100 and A40 models. Much information is still missing from these proposals, but we know that The A30 is based on a GA100 GPU and offers 24 GB of HBM2 memory on a 3072-bit bus for a bandwidth of 933 GB / s and a TDP of 65W. In the case of A10instead, we have a chip GA102 con 9216 CUDA core, 288 Tensor core and 72 RT core supported by 24 GB of GDDR6 memory. Thanks to the 384-bit bus, the bandwidth reaches 600 GB / s. The TDP, in this case, is equal to 150W. Nvidia A10 Last but not least, Nvidia A16. We are faced with a "special" product if you pass the term there because it sees the presence of four GPU Amps on a single PCB. Each chip is accompanied by 16GB of GDDR6 memory, for a total of 64GB. Nvidia A16 proposes itself as a multimedia accelerator (offers four NVENC encoders and eight NVDEC decoders) or a vGPU solution. Nvidia A16 All datacenter models support PCIe 4.0 and have no video outputs, but only the A100, A40 and A30 can be combined with the same model via NVLink. In all cases, the cooling is passive and the power supply is entrusted to an eight-pin EPS12V connector. A30 and A10 should be available by the end of the month, while A16 will have to wait until the end of the year. Read the full article

🌉 Bridging a typed and an untyped world

Even if you work in the orderly, bug-free, spic-and-span, statically-typed worlds of Elm and Haskell (like we do at NoRedInk, did you know we’re hiring?), you still have to talk to the wild free-wheeling dynamically-typed world sometimes. Most recently: we were trying to bridge the gap between Haskell (🧐) and Redis(🤪). Here we’ll discuss two iterations of our Redis library for Haskell, nri-redis.

All examples in this code are in Haskell and use a few functions from NoRedInk’s prelude nri-prelude. Specifically, we will use |> instead of &, Debug.toString instead of show and a few functions from Expect. Most of the example code could be real tests.

💬 Redis in Haskell

Let’s begin with a look at an earlier iteration of nri-redis (a wrapper around hedis). We are going to work with two functions get and set which have the following type signatures:

set :: Data.Aeson.ToJSON a => Text -> a -> Query () get :: Data.Aeson.ToJSON a => Text -> Query (Maybe a)

Let’s use this API for a blogging application that stored blog posts and users in Redis.

data User = User { name :: Text -- maybe more fields later } deriving (Generic, Show, Eq) data Post = Post { title :: Text -- ... } deriving (Generic, Show)

Maybe you noticed that we derive Generic for both types. We will store users and posts as JSON in Redis. Storing data as JSON in Redis is simple, and we only need an additional instance for decoding and encoding to JSON.

instance Data.Aeson.ToJSON User instance Data.Aeson.FromJSON User instance Data.Aeson.ToJSON Post instance Data.Aeson.FromJSON Post

Now how do we write something to Redis?

Redis.set "user-1" User { name = "Luke" } -- create a query |> Redis.query handler -- run the query |> Expect.succeeds -- fail the test if the query fails

We use Redis.set, which corresponds to set. We can then execute the query using Redis.query. We can read the data back using a get.

maybeUser <- Redis.get "user-1" |> Redis.query handler |> Expect.succeeds Expect.equal (Just User {name = "Luke" }) maybeUser

🐛 What can go wrong?

Now that we know how to read and write to Redis let’s look at this example. Can you spot the error?

let key1 = "user-1" let key2 = "post-1" Redis.set key1 User { name = "Obi-wan Kenobi" } |> Redis.query handler |> Expect.succeeds Redis.set key1 Post { title = "Using the force to wash your dishes" } |> Redis.query handler |> Expect.succeeds maybeUser <- Redis.get key1 |> Redis.query handler |> Expect.succeeds Expect.equal (Just User {name = "Obi-wan Kenobi"}) maybeUser -- !!! "Could not decode value in key: Error in $: parsing User(User) failed, key 'name' not found"

A runtime error?! in Haskell?! Say it ain’t so.

Maybe you spotted the bug: We are using key1 to set the post instead of key2.

First, we set the data in key1 to be a User

We then replaced it with a Post.

We fetch the data from key1 (a Post) into maybeUser.

The compiler thinks maybeUser is of type Maybe User, because we compare it with Maybe User in Expect.Equal.

At runtime, the generated code from the FromJSON instance will then fail to decode the Post’s json-serialization into User.

which will cause our program to crash.

This is not the only thing that can go wrong! Let’s consider the next example:

let users = [ ("user-1", User { name = "Obi"}) , ("user-2", User { name = "Yoda"}) ] Redis.set "user-1" users |> Redis.query handler |> Expect.succeeds maybeUser <- Redis.get "user-1" |> Redis.query handler |> Expect.succeeds Expect.equal (Just User { name = "Obi"}) maybeUser -- !!! "Could not decode value in key: Error in $: parsing User(User) failed, expected Object, but encountered Array"

We called set with users instead of a User (or called Redis’s mset on the list users). Again, this compiles but fails at runtime when we assume that we receive one User when we call get for this key.

🛡️ Can we make the bug impossible?

The previous examples showed how easy it was to write bugs with such a generic API—the program compiled in both cases but failed at runtime. The compiler couldn't save us because set and get both accept any Text as a key and only constrain the value to have an instance of To/FromJSON.

-- reminder: the API that allowed all kinds of havoc set :: Data.Aeson.ToJSON a => Text -> a -> Query () get :: Data.Aeson.ToJSON a => Text -> Query (Maybe a)

Want to set a User and fetch a list of Posts from the same key? This API will let you (and then fail loudly in production).

Ideally, we would get a compiler error that prevents mixing up keys or passing the wrong value when writing to Redis. We decided to use an Elm-ish approach, avoiding making the API too magic.

Instead of using commands directly, we introduced a new type called Redis.Api key value. Its purpose is to bind a concrete type for key and value to commands.

Let’s try to make the same mistake we made earlier, using the wrong type, with our new Redis.Api. Let’s first create such an Api.

newtype UserId = UserId Int userApi :: Redis.Api UserId User userApi = Redis.jsonApi (\userId -> "user-" ++ Debug.toString userId)

We bound UserId to User by adding a top-level definition and giving it a type signature. Additionally, we created a newtype instead of relying on Text as the key. This will guarantee that we don’t call userApi with a post key.

Now to use this, we call functions by “passing” them the new userApi. Side note: Redis.Api is a record, and we get the commands from it.

let users = [(UserId 1, User { name = "Obi"}), (UserId 2, User { name = "Yoda"})] Redis.set userApi (UserId 1) users |> Redis.query handler |> Expect.succeeds

We catch the bug at compile time without writing a test (and well before causing a fire in production).

• Couldn't match expected type ‘User’ with actual type ‘[(UserId, User)]’ | 325 | Redis.set userApi key1 users | ^^^^^

🤗 Making Tools Developer-Friendly

Our initial Redis API used a very generic type for keys and values (only constraint to implement To/FromJSON). This optimized the library for versatility but made the resulting application code less maintainable and error-prone.

Having concrete types provides the compiler with more information and therefore allows for better error messages and better maintainability (e.g., less error-prone). The API we ended up with is a balance of simplicity and safety. It’s still possible to misuse the library and get the bugs we discussed, but it guides the user towards the intended usage.

You can’t always predict how your library’s users will use your tools, so leaving them open-ended has its upsides. But if you have a specific use-case, solving it specifically will help your developers avoid pitfalls and keep them more productive.
