海外TECH	Engadget	East Beast and West Pest review: affordable intros to the addictive world of modular synths	https://www.engadget.com/cre8audio-east-best-and-west-pest-cheap-modular-synthesis-review-143003424.html?src=rss	East Beast and West Pest review affordable intros to the addictive world of modular synthsThe price of entry into the world of modular synthesis has been trending downward for sometime Moog even recently released the Mavis a DIY Eurorack compatible synth for just a shockingly low price from the company But CreAudio seems to think that prices haven t come down fast enough It has been setting the pace in an incredible race to the bottom and I don t mean that as a bad thing In May CreAudio announced the East Beast and West Pest its first pair of self contained synths for just They re some of the cheapest analog semi modular synths that I m aware of save for the Korg Volca Modular which is sort of a weird dead end on the synth family tree What they shareUnsurprisingly the East Beast and West Pest have a lot in common The basic chassis is the same both have a point patchbay a step sequencer an arpeggiator a one octave keyboard an LFO and a digital multi mod tool Even the core oscillator is very similar with the West Pest having most of the same waveshapes and a slightly “buzzier tone It s the rest of the sound shaping modules that set the two apart from each other with the East Beast and West Pest predictably leaning into East Coast and West Coast synth styles respectively The build quality on both is about what you d expect from something at this price point There s a lot of plastic and don t seem like they re designed with the rigors of your life in mind They don t feel cheap or toy like though they just feel like what they are entry level synthesizers The larger knobs are easier to handle than the tiny ones on a Volca and the overall package feels a touch more robust than an IK Multimedia Uno They re also a lot more fun looking than those instruments I know that the almost comicbook esque aesthetic here won t be everyone s cup of tea but I quite enjoy it It s playful and a bit silly and let s not forget synths should be fun Terrence O Brien EngadgetThe keyboard is a welcome inclusion perfect for auditioning patches or punching in sequences and arps But like the one on Moog s Mavis I wouldn t want to actually rely on it for performance The keys are small and a little wobbly Plus most of the keys have two additional shift functions for controlling various features Honestly the better bet is to use an external controller and set the built in keyboard to default to the yellow green functions instead This is made easier by the fact that both the East Beast and West Pest have MIDI inputs and MIDI to CV converters for controlling other parameters That s not unheard of on a budget semi modular synth but it s not a given either Even some of Moog s more expensive instruments like the DFAM don t have MIDI support I will make one minor note here though MIDI notes were quite a few octaves higher than expected straight out of the box and I was initially a bit confused until I found the instructions for changing the octave offset in the manual One of the more unique shared features is the digital multi mod tool Since they only have one LFO and one envelope generator or “dynamics section in the case of the West Pest this gives the instruments an extra set of controls to draw on This can be an additional LFO envelope random generator or MIDI to CV output There are some limitations for instance you can only map a single MIDI CC and the envelope is a simple decay envelope with seven preset rates but it s a nice addition nonetheless It s a similar story with the sequencer and arpeggiator They get the job done and I m glad they re here but both are pretty basic The arpeggiator only has two modes as played and random While the sequencer can be steps you basically just add notes to the end until you re happy with it If you make a mistake your only option is to clear the whole thing and start over While dialing in basic sounds and patches is pretty straightforward there are a bunch of options and features hidden behind those shift functions And navigating them isn t always intuitive Obviously I m not expecting a giant display with detailed graphics on a synth but the “ bit display read four LEDs in a line can feel arcane at times I ve had both for over a month now and I still have to refer to the manual to remember that the first two LEDs mean I m dividing the clock by two for the LFO or that the first third and fourth lights mean I ve set the swing to percent This is obviously not a deal breaker by any means But if you re the type of person who proudly refuses to read manuals you might feel frustrated at times East BeastTerrence O Brien EngadgetLet s dig into the more “normal of the two instruments This is probably what most people envision when they think of a synthesizer A big rich oscillator a filter for shaving off harmonics and an ADSR envelope for controlling amplitude While this doesn t really sound like a Moog it clearly shares a similar lineage The multi mode filter and oscillator are straight from boutique synth makers Pittsburgh Modular which gives this decidedly budget affair some serious street cred The oscillator has sine triangle saw and square waves and you can combine two of them to deliver thicker more unique sounds when needed It s something that Pittsburgh Modular has been perfecting for around years It does sound pretty massive Being a mono synth you re not gonna get compelling pads out of the East Beast but it shines as a lead and bass machine It can do big room shaking low end thick creamy solos and delicate high end plucks It even has pulse width modulation for the square wave which gets you wonderful video game noises and FM for harsher more bell like tones I actually think it s at its best playing softer leads using the filter to shave off a lot of the high end The filter is probably the star of the show by the way Often it s what brings the most character to the sound of a synth and this one delivers It s variable state going from low pass to band pass to high pass But it can also combine those in interesting ways It does acid bass lines and nasal reedy sounds There s a reason the filter cutoff knob is about four times larger than all the other controls on the front panel It s probably the most powerful tool here for shaping your sound Both CreAudio and Pittsburgh Modular like to brag that this unique filter has “no dead spots that it s really “all one large sweet spot and you know what they re probably right I had a real hard time making this filter sound bad No matter how much you crank the resonance in every mode even with the filter mod set to ludicrous levels it s surprisingly musical It doesn t self oscillate which might be a bummer for some but it doesn t bother me too much West PestTerrence O Brien EngadgetThe West Pest is sort of like the East Beast s hippy cousin It s a tad strange and has to do everything a little differently but it s no less compelling just a bit tougher to tame It has many of the same features and a very similar oscillator but it trades the variable state filter and ADSR envelope for a lowpass gate and adds a wave folder I d venture to say that similar to the East Beast the Pest is most comfortable with bass and plucky leads But the timbre is completely different It s more aggressive and sharp trading in the creamy goodness of its counterpart for the plasticky weirdness more often associated with Buchla synths Because it travels in less familiar territory it can feel a little harder to make work in an arrangement But it can be a more satisfying solo instrument Both synths have robust randomization features including randomly cycling through oscillator waveforms and generative sequencing capabilities but those feel more at home on the West Pest Terrence O Brien EngadgetSetting the digital mod tool to random and connecting it to the release mod jack will alter how long notes ring out Then using the random pattern generator with morphing will play a continuously evolving sequence And then you can get the oscillator wave to change for every note giving you something truly unpredictable Feed that through an epic reverb pedal and you ve got a custom soothing soundtrack for working or reading to Yes you could accomplish a similar thing with the East Beast since it has most of the same randomization tools save the release mod and it s probably the more versatile instrument but I find the results on the West Pest more pleasing And honestly this is one of the ways I often use synths in my studio passively as a sort of fidget toy or to set a mood while I plug away on editing articles for Engadget With other gearThe one thing I will say is that the West Pest does need a little external help to shine more so than the East Beast Its rubbery bass sounds are pretty usable on their own but once you start getting into the higher frequencies reverb and delay become a must But what you re probably more interested in is how they interact with other modular gear The point patchbay makes it simple to integrate into a larger Eurorack or compatible setup whether these are your gateway drug or just the latest symptom of your incurable GAS gear acquisition syndrome Terrence O Brien EngadgetI would say the patchbay is probably where you make the most trade offs here though While there are indeed patch points evenly divided between ins and outs four of them are dedicated to MIDI functions and one is the audio output So that leaves points for internal patching Now that both of these act as a MIDI to CV interface is extremely useful and can simplify controlling other gear that isn t MIDI compatible For instance you could feed MIDI from your computer to the West Pest then pass those controls on as CV to something like Moog s Mavis But it does eat into the options available to you for sound design on board It would be great to have access to the LFO rate or resonance level on the patch bay for example Or to have a few utilities like a mult CreAudio crams a lot of versatility into the patchbay through the multi mod tool which gives you an extra envelope LFO or a random generator though it also has limitations There s enough power here to get you exploring the basics of patch design but you ll probably start wishing for a few more ins and outs sooner than later Wrap upThe East Beast and West Pest are both undeniably impressive values At this price point there s simply nothing like them on the market They are usable and musical semi modular synths with unique and compelling features What s more they re easy to integrate with other modular gear and you can even take them out of their cases and mount them in a larger Eurorack set up They re near ideal choices for someone that s looking to learn synthesis That is different from saying they re an ideal first synth full stop If you re just looking to pull up some great sounding presets and get on with your day these are not for you CreAudio s instruments demand exploration and experimentation And recalling a patch will require you to take copious notes However if you ve ever watched a YouTube video of someone s monstrous modular rack with unbridled jealousy these are a good place to start your journey	2022-12-01 14:30:03

GCP	Cloud Blog	Cloud Pub/Sub announces General Availability of exactly-once delivery	https://cloud.google.com/blog/products/data-analytics/cloud-pub-sub-exactly-once-delivery-feature-is-now-ga/	Cloud Pub Sub announces General Availability of exactly once deliveryToday the Google Cloud Pub Sub team is excited to announce the GA launch of exactly once delivery feature With this availability Pub Sub customers can receive exactly once delivery within a cloud region and the feature provides following guarantees No redelivery occurs once the messages has been successfully acknowledgedNo redelivery occurs while a message is outstanding A message is considered outstanding until the acknowledgment deadline expires or the message is acknowledged In case of multiple valid deliveries due to acknowledgment deadline expiration or client initiated negative acknowledgment only the latest acknowledgment ID can be used to acknowledge the message Any requests with a previous acknowledgment ID will fail This blog discusses the exactly once delivery basics how it works best practices and feature limitations Duplicates Without exactly once delivery customers have to build their own complex stateful processing logic to remove duplicate deliveries With the exactly once delivery feature there are now stronger guarantees around not delivering the message while the acknowledgment deadline has not passed It also makes the acknowledgement status more observable by the subscriber The result is the capability to process messages exactly once much more easily Let s first understand why and where duplicates can be introduced  Pub Sub has the following typical flow of events Publishers publish messages to a topic Topic can have one or more subscriptions and each subscription will get all the messages published to the topic A subscriber application will connect to Pub Sub for the subscription to start receiving messages either through a pull or push delivery mechanism In this basic messaging flow there are multiple places where duplicates could be introduced  PublisherPublisher might have a network failure resulting in not receiving the ack from Cloud Pub Sub This would cause the publisher to republish the message Publisher application might crash before receiving acknowledgement on an already published message SubscriberSubscriber might also experience network failure post processing the message resulting in not acknowledging the message This would result in redelivery of the message when the message has already been processed Subscriber application might crash after processing the message but before acknowledging the message This would again cause redelivery of an already processed message Pub SubPub Sub service s internal operations e g server restarts crashes network related issues resulting in subscribers receiving duplicates It should be noted that there are clear differences between a valid redelivery and a duplicate A valid redelivery can happen either because of client initiated negative acknowledgment of a message or when the client doesn t extend the acknowledgment deadline of the message before the acknowledgment deadline expires Redeliveries are considered valid and the system is working as intended A duplicate is when a message is resent after a successful acknowledgment or before acknowledgment deadline expiration Exactly once side effects“Side effect is a term used when the system modifies the state outside of its local environment In the context of messaging systems this is equivalent to a service being run by the client that pulls messages from the messaging system and updates an external system e g transactional database email notification system It is important to understand that the feature does not provide any guarantees around exactly once side effects and side effects are strictly outside the scope of this feature For instance let s say a retailer wants to send push notifications to its customers only once This feature ensures that the message is sent to the subscriber only once and no redelivery occurs either once the message has been successfully acknowledged or it is outstanding It is the subscriber s responsibility to leverage the email notification system s exactly once capabilities to ensure that message is pushed to the customer exactly once Pub Sub has neither connectivity nor control over the system responsible for delivering the side effect and hence Pub Sub s exactly once delivery guarantee should not be confused with exactly once side effects How it worksPub Sub delivers this capability by taking the delivery state that was previously only maintained in transient memory and moving it to a massively scalable persistence layer This allows Pub Sub to provide strong guarantees that no duplicates will be delivered while a delivery is outstanding and no redelivery will occur once the delivery has been acknowledged Acknowledgement IDs used to acknowledge deliveries have versioning associated with them and only the latest version will be allowed to acknowledge the delivery or change the acknowledge deadline for the delivery RPCs with any older version of the acknowledgement ID will fail Due to the introduction of this internal delivery persistence layer exactly once delivery subscriptions have higher publish to subscribe latency compared to regular subscriptions Let s understand this through an example Here we have a single publisher publishing messages to a topic The topic has one subscription for which we have three subscribers Now let s say a message in blue is sent to subscriber At this point the message is outstanding which means that Pub Sub has sent the message but subscriber has not acknowledged it yet This is very common as the best practice is to process the message first before acknowledging it Since the message is outstanding this new feature will ensure that no duplicates are sent to any of the subscribers  The persistent layer for exactly once delivery stores a version number with every delivery of a message which is also encoded in the delivery s acknowledgement ID The existence of an unexpired entry indicates there is already an outstanding delivery and that we should not deliver a message providing the stronger guarantee around the acknowledgement deadline An attempt to acknowledge a message or modify its acknowledgement deadline with an acknowledgement ID that does not contain the most recent version can be rejected and a useful error message can be returned to the acknowledgement request Coming back to the example a delivery version for the delivery of message M in blue to subscriber will be stored internally within Pub Sub let s call it delivery This would track that a delivery of message M is outstanding Subscriber successfully processes the message and sends back an acknowledgement ACK The message is then removed eventually from Pub Sub pertaining to the topic s retention policy  Now let s consider a scenario that could potentially generate duplicates and how Pub Sub s exactly once delivery feature guards against such failures An exampleIn this scenario subscriber gets the message and processes it by locking a row on the database The message is outstanding at this point and an acknowledgement has not been sent to Pub Sub Pub Sub knows through its delivery versioning mechanism that a delivery delivery is outstanding with subscriber Without the stronger guarantees provided by this feature a message could be redelivered to the same or a different subscriber subscriber while it is still outstanding This would cause subscriber trying to get a lock on the database for the update resulting in multiple subscribers trying to get locks for the same row causing processing delays Exactly once delivery eliminates this situation Due to the introduction of the data deduplication layer Pub Sub knows that there is an outstanding delivery which is unexpired and it should not deliver the same message to this subscriber or any other subscriber Using exactly once deliverySimplicity is a key pillar of Pub Sub We have ensured that the feature is really easy to use You can create a subscription with exactly once delivery using the Google Cloud console the Google Cloud CLI client library or Pub Sub API Please note that only pull subscription type supports exactly once delivery including subscribers that use the StreamingPull API This documentation section provides more details on creating a pull subscription with exactly once delivery Using the feature effectivelyConsider using our latest client libraries to get the best feature experience You should also use new interfaces in the client libraries that allow you to check the response for acknowledgements Successful response will guarantee no redelivery Specific client libraries samples can be found here C C Go Java Node js PHP Python RubyTo reduce network related ack expirations leverage minimum lease extension setting Python Node js Go MinExtensionPeriodin LimitationsExactly once delivery is a regional feature That is the guarantees provided only apply for subscribers running in the same region If a subscription with exactly once delivery enabled has subscribers in multiple regions they might see duplicates For other subscription types push and BigQuery Pub Sub initiates the delivery of messages and uses the response from the delivery as an acknowledgement the message receiver has no way to know if the acknowledgement was actually processed In contrast pull subscriber clients initiate acknowledgement requests to Pub Sub which respond with whether or not the acknowledgement was successful This difference in delivery behavior means that exactly once semantics do not align well with non pull subscriptions To get started you can read more about exactly once delivery feature or simply create a new pull subscription for a topic using Cloud Console or the gcloud CLI Additional
