#adhoc testing

[fandroidrobotheadcanons]

ik that this is a rlly popular idea in the fandroid fandom already, but i feel like frogbot def has a spring w/ a suction cup on the end to move around instead of a wheel

CR twitter having a normal one and deciding CR is the end all be all of targeted activism

I have seen these posts get like 500 likes asking CR to donate and then Matt’s response where he talks about poor mental health but says that he’s given 15k of their own money to Gaza is like, clear they align with a pro Palestine position. And this response has got 28k likes. It’s a very online bubble talking to each other, and they cannot see that they’re posting the same information to each other and aren’t changing any damn minds.

Very high possibility CR can’t say anything on the Critical Role accounts because of their contracts with Amazon. So what if they never post for these people? Maybe just give up and move on?

When I first got into the fandom I saw all this cool clothing merch so I looked for their code of ethics. Couldn’t find one. Emailed the shop/site about it, never got a response. Gave up and moved on.

My genuine position it’s nice when they do do something good, but I have no expectations otherwise, they’re not an ethical company they’re a business.

And it’s totally normal to be disappointed and want to spend your money and time elsewhere, I’m not here to tell you you’re wrong, but I think some twitter activists people have lost sight of a bigger picture by being in a bubble. I just don’t care to centre a damn media company in my activism and have better things to worry about than fucking Critical role.

Like I donate monthly anyway and adhoc donations. I wouldn’t donate to a fundraiser unless there was something amazing offered during it, as a) I prefer to just give straight to the charity as I think that avoids processing fees b) it probably wouldn’t even be in my timezone? Idk people can just donate anyway, people are already well organised and you don’t need Critical Role to do it for you.

Support who you want, but turning other fans not boycotting critical role, the DnD media company, into a litmus test if you’re a good person or not a bit ridiculous here, and a bit unserious.

fine l bite. what is fandroid

i giggled like a little idiot reading this ask. OK SO. uh. fandroid is a youtuber! a group of youtubers actually. just a couple guys acting. and the characters they play are robots! fandroid started out as just one guy running a kids' yt channel but after a hiatus of ~3 years he came back with what's essentially a reboot. they play video games and stuff. the original fandroid's lore was very few and far between- basically there's these robotics companies, ADHOC and QUALIA. Fandroid and the majority of the characters we see were built by ADHOC. and ADHOC... kind of sucks!!! shady practices and all that. Fandroid and his fellow robots were NOT TREATED WELL IN THE SLIGHTEST! he was locked in one room for his Entire life, except for a few times where he was taken to other places to be tested and experimented on. yikes. he was SUPPOSED to be all alone, until one day Melody- another character- broke in through the vents and basically said "this guy is my friend now." Melody is a runaway robot from QUALIA. the kind of robot she is, a series of toys called Drone Buddies, is made to imprint on one specific human kid and be their bff. melody is broken. she chose fandroid instead! being a product from ADHOC's rival company, ofc ppl didn't like her. little menace to everyone INCLUDING fandroid (she threw a toaster at his head at one point) but its ok theyre fine im sure this friendship is healthy and normal! there's also a few prototypes, the three main ones are Beep-0, the first prototype, Frogbot, the silliest little guy around, and Fandrew, the one i'm obsessed with. i hate him. i need him to be okay. he's insane.anyway. some big Event happened leaving all the humans at adhoc Dead. sad! well there's other companies. around this time Fandroid was put into a kind of. stasis? hibernation? he was asleep(deactivated?) for a LOOOOOONG time. from 2020 to around the end of this year's january. but he's back! he's okay! i'm sure this won't do anything negative for his mental health!!! so things are okayish for a while.

and then robots start going missing.

Business Bot, a rather obscure character no one really talked about much anyway, was dismantled. Panic spread throughout the remaining robots at the facility.

Enter 404. A new character who wasn't in the original Fandroid. An error message given life, he now seeks a physical form, tearing off pieces of other robots to build onto himself. He got Business Bot, a little bit of Frogbot and is now going after the others...

However, he sucks at this. He's sooooo cringefail i need to shove him into a locker. he's the worst. people want to kiss him. people want him and beepo to kiss. robot yaoi.

so thats what ive been obsessing over for the past few months. hi twip

[mourning-again-in-america]

this surely has been written about but idk where

one of the big things software does at my grocery store job is it allows a delocalization of policy controls

if I need to clear an item off the current order so I can start afresh, because it doesn't end in a purchase, I need to call for a manager, who has a key card to permit this

I assume back in the day receipts had a notation for these sorts of things that you needed to store in your register likely with a stamp or initialization of approval, but a manager could shout an adhoc override of the override and you would note it and all could proceed

but these ad hoc policy changes based on the needs of the moment are incredibly important and so much of the infrastructure has been baked into an always correct, always networked computer

the computer cannot be trusted to always be correct and its errors are sharp and irrecoverable without drastic action that often takes hours, if not days.

on the one hand, private equity hollowing out enterprise software (of which POSs are an epitome) is a great fear of mine and I think there's good arguments that this should be treated as a national security crisis for CISSA to issue legally binding guidance on but that might just be that "national security" is the best way to get the govt involved where it shouldn't be

on the other hand, one of the few good results of the FAANG layoffs is the making more likely of greater diffusion of proper software architecture and testing, such as how to build a system that lets you mock the terminals as state machines & experiment with worst-case scenarios. but will it happen?

[mage-ical-character-person]

So. Beep-0 is back

Which is weird, right? We KNOW he was “decommissioned and destroyed” and Fandroid tells us “I think there was only ever one Beep-0 in the first place” in one of his Baldi’s Basics videos around 4:44

Fandroid’s wording here is kind of interesting though. He thinks there was only one Beep-0 in the first place

I’m fairly convinced that this is not the same Beep-0 we know from the first video with Beep-0 (or if it is, he’s been seriously reprogrammed and repurposed) because

this Beep-0 can talk, first of all

He says he’s too busy not blowing up the world with missiles to play Roblox but looking at his introduction video… he’s playing ROBLOX and enjoying it.

The Beep-0 from the livestream is in charge of several things at ADHOC including missiles. The original Beep-0 was a prototype of Fandroid and as such a Let’s Playing robot, who, based on the message at the end of his video being on what to do if a robot escapes its test chamber, disobeyed ADHOC and tried to escape. Why keep a disobedient robot around and PUT HIM IN CHARGE OF THE MISSILES. I know ADHOC’s low on funds but really.

Then of course, there’s stuff like this.

If there was only one Beep-0 that was decommissioned so long ago, how is he planning Halloween costumes with the other ADHOC robots (and Melody) in 2018?

And then. This. This Beep-0 looks like the kinda thing that would be a security system in charge of missiles. It’s also clearly not the cube on a stick we know Beep-0 as, yet Fandroid describes the fanart as accurate. For a while my theory/headcanon was that after Beep-0 attempted to escape, they destroyed his old body and stuck him in this now-immobile form to keep him from trying to leave again and maybe as some kind of punishment. But again, who puts a misbehaving robot in charge of the missiles?

That’s what makes me think this is a new or drastically reprogrammed Beep-0. His “purpose” is different and the personality from his first video is replaced with cynicism and a focus on how important his job as ADHOC’s security system/smart thermostat/missile control is.

It reminds me of one of the messages in the ADHOC lobby in the RP

“…And we actually might even come to advertise these as consciousness-free.”

Which is followed up with a different voice saying

“ Everything is conscious, but some things are more conscious then others.”

(also Beep-0 bragging about his singing skills was really funny to me because like. This exists)

Much to think about…

The 3 fandroids from oldest to newest

Ethan (formally evil fandroid) model age 7

Has the same purpose as fandroid to entertain but with mainly reacting to videos online but none of them have seen by the public since he became rouge in the weeks of testing.

Unique feature- his model didn't have any hands like fandrew and has a shut down button on his back and runs on batteries.

Fandroid model age 6

His purpose is to entertain though music and gaming particularly ones on PC since he did have hands but only in a claw form.

Unique feature- being able to engage with his audience being able to go live with little errors

Darkdroid model age 2

After fandroid went rogue ADHOC made a model with the purpose of capturing fandroid. Its a model was purposed to be worn by a human but midway during development, the project was cut due to it being a high risk if the model collapses into the person body if they don't fit. So it was sold off .

Unique feature- since it's built to fit for a human it actually have legs and proper hands. The arm cylinders have built in katars and has 9 cameras all over the body to give it's user 360⁰ vision. These the the features that made through before being cut but it's unsure what the model could look like if completed

Selecting and Configuring Inference Engines for LLMs

There are many optimization techniques developed to mitigate the inefficiencies that occur in the different stages of the inference process. It is difficult to scale the inference at scale with vanilla transformer/ techniques. Inference engines wrap up the optimizations into one package and eases us in the inference process.

For a very small set of adhoc testing, or quick reference we can use the vanilla transformer code to do the inference.

The landscape of inference engines is quickly evolving, as we have multiple choices, it is important to test and short list the best of best for specific use cases. Below, are some inference engines experiments which we made and the reasons we found out why it worked for our case.

For our fine tuned Vicuna-7B model, we have tried

TGI 

vLLM

Aphrodite 

Optimum-Nvidia

PowerInfer

LLAMACPP

Ctranslate2

We went through the github page and its quick start guide to setup these engines, PowerInfer, LlaamaCPP, Ctranslate2 are not very flexible and do not support many optimization techniques like continuous batching, paged attention and held sub-par performance when compared to other mentioned engines.

To obtain higher throughput the inference engine/server should maximize the memory and compute capabilities and both client and server must work in a parallel/ asynchronous way of serving requests to keep the server always in work. As mentioned earlier, without help of optimization techniques like PagedAttention, Flash Attention, Continuous batching it will always lead to suboptimal performance.

TGI, vLLM and Aphrodite are more suitable candidates in this regard and by doing multiple experiments stated below, we found the optimal configuration to squeeze the maximum performance out of the inference. Techniques like Continuous batching and paged attention are enabled by default, speculative decoding needs to be enabled manually in the inference engine for the below tests.

VisionOS App Development Company

VisionOS App Development Services by Agicent

We’ve started learning and honing our skills on VisionOS from the day it was launched in 2023 and now when the device is actually here, we are getting overwhelming requirements for our VisionOS App development services and we offer a complete spectrum of services which are useful for all sizes of projects and startups.

VisionOS App Discovery Session & Consulting Service

In this step, we understand your product vision and the market you want to cater. We gather all your requirements (feature list, use-case, goal, monetization methods and goals, integrations, future vision etc) and consult you on the best features for the MVP or for full product, and also do a competitor analysis to let you know the gaps in the market and propose you the best possible solution. We also lay out a scope of the work and provide you either a fixed price estimation for the VisionOS App development or offer you a dev team on month-on-month basis with these pricing plans.

You can book a Free VisionOS App Discovery Session from here.

VisionOS Apps Design, Wireframes, Prototyping Service

In this step, we convert your feature list into visual design and wireframes. This is the most crucial step among all others as whatever we are going to launch in the market is visualized and finalized here. We closely coordinate with you at this stage, figure out what kind of target market we have and what type of design would they like, and then create the design and simulate that like a clickable prototype or a demo video like this example.

We send these design visualizations for your feedback and approval and do as many iterations as you want and once approved we proceed towards the actual development.

Tech Architecture and Coding Phase: Agile Sprints

Once design is approved, we create the tech architecture to achieve what we have visualized in terms of the design and functionality. And the next step is coding the VisionOS App using SwiftUI, ARKit, Unity, Xcode, ComposerPro tech stacks as well as backend technologies like Node.js, MongoDB or likes.

We create the tech architecture keeping a larger future vision in mind so the MVP VisionOS App we develop today assuming for a small amount of users, should be scaled easily and quickly to cater millions of the users and more advanced features and also leave a lot of room for future integrations with different technologies. Usually our CTO and Engineering leads do the architecture job.

The whole project is broken down into small feature bunches and then they Weekly Agile Sprints are schedule to achieve those features week by week. At every weekend a progressive Adhoc VisionOS App build is released for testers and clients for the UAT. Any bugs or enhancements are noted down and added with the next week’s dev sprint and the build is shipped to either live or test server depending upon your priorities.

Adhoc Distribution and Final go-live

During the development phase, the visionOS App is distributed across a private network (of clients, early users/ testers, dev teams) as an Adhoc build that we create using Apple’s guidelines and protocols on its iTunes connect ecosystem integrated with the Xcode and other tech stacks associated with the VisionOS App Development.

The final App store submission is done when the Dev cycle is complete and you give us a go ahead to go live. We do the whole job for you.

The whole solution is also ported onto the live cloud server and infrastructure using our DevOps experts.

VisionOS App Maintenance, Enhancements, Upkeep

Once the first version goes live, you can either switch to the maintenance phase for the upkeep of the VisionOS App or can go about launched further features for enhancements. Our Dev and maintenance plans starts from as low as $ 2900 mo and sometimes even lesser if you only need under 100 hours of maintenance a month.

Like advanced mobile apps, VisionOS Apps also utilizes various third party APIs from user authentication to several other features like integration with maps, payment gateways, with other apps and backend and all such APIs launch new updates very frequently and hence the VisionOS app will have to be updated accordingly. Also the VisionOS itself is in its nascent stage right now and we can expect atleast 10 major or minor OS upgrades this year and for which a regular support & maintenance service will be required.

By offer Development, Design, Marketing, Maintenance, Porting services we make ourselves as you one stop VisionOS App Development Company.

VisionPro App Porting Services

Here we work to make your existing web app or mobile app to be absolutely compatible and oriented towards the new VisionPro Devices and VisionOS Operating system. You can leverage your existing product and userbase and scale them for VisionOS VisionPro device.

We’ll consult you in identifying which features can be ported onto VisionOS as is and which ones need to be made cmpatible and adaptable to the visionOS unique spatial features.

In most of the existing mobile apps, voice gesture commands and eye commands will be added as a go-to features when it comes to porting on to the visionOS and then more options can be added as the app grows.

VisionPro App Marketing Services

We render our inhouse marketing and sales expertise, tools and workflows for our clients and craft highly efficient and performance-oriented performance marketing campaigns to promote your VisionPro App.

This can include (but not limited to) – Paid ad campaigns to install VisionOS Apps across big outlets like Google, Meta/ FB/ Insta, Linkedin; organic SEO and organic campaigns, Organic and paid PR campaigns, Video content marketing, influencer marketing, Opinion leadership influenced market, Cross App integration promotion and so on.

You tell us your monthly App marketing budget and goal and we’ll craft and run and optimize the best campaign inside that.

Benefits of creating VisionOS Apps for Startups and Business

Clear Competitive Edge: The early mover advantage

It’s a very new device and have only started being sold in some parts of the US only. Anyone moving first for this device is definitely going to get a lot of advantage in terms of targeting the niche and comparatively upscale user-base.

Even the existing Apps that will scale for VisionPro Device exploiting its AR/ VR spatial capabilities are going to offer enhanced experience to its existing user base and gain more customer loyalty and branding.

A new world of opportunity to Innovative

For the same reasons as stated above, its spatial computing capabilities have opened a whole new world of amazing innovation opportunities. We’ve listed below some of the possible innovative use cases for various industries on this page itself, and we believe that there will be millions of amazing use cases out there that can solve the current world problems in much better ways than what is being done by the current smartphone device and apps.

Integrating the VisionOS apps with different devices will offer great possibility to further innovate as well where several interconnected devices sharing and exchanging data will proide more seamless convenient life to the user especially for healthcare, home automation, and business usage.

Unique and Immersive Experience

Vision Pro’s unique spatial computing, tracking and depth perception allow for highly realistic and interactive experiences in augmented reality (AR) and Virtual reality. Users can experience and manipulate virtual objects in a natural human way and that will create a sense of real presence and break down the barrier between the physical and virtual digital world.

Any app utilizing these spatial immersive capabilities are going to be used more and more by the users compared to regular mobile or web apps and therefore launching an app on VisionOS gives you a more loyal and consistently engaged user-base.

Better interactive Storytelling

You can tell your story in more interactive and appealing way when it looks and feel closer to the reality and that is exactly what Visionpro device offers to its users. Businesses as well as creators can create and tell immersive mixed reality stories that can actually engage users for a longer span than just scrolling back in few seconds.

A historical content creator can create virtual historical battles that you can see happening in front of your eyes, or or viewing ancient battles unfold right before your eyes. Or a virtual story showcasing you the world of dinosaurs as a moving and sounding reality.

Same goes for product visualization as we’ve discussed the same concept in details below in Ecommerce Use-case. You can showcase and appeal your product with a realistic experience, creation of immersive demos and free trials can help marketers win the consumer’s confidence to a higher degree than what you are able to do with the old technologies.

Story is everything, and VisionOS allows you to tell your story in the best way possible so far in the history of the mankind.

VisionOS App development is not complex

Creating mixed reality Apps have always been a complex and typical exercise compared to the conventional software development, especially because of the demand of creating interactive virtual reality UI and UX. However, VisionOS has already done majority of the heavy lifting and if developers are familiar with Apple iOS development and Arkit (which our developers are) then creating VisionOS Apps using the same skill sets becomes really easy.

Its juts a transition of the device and the change of UI, while rest of the technologies will be as same as iOS developers have been using for the last few years.

Process of Creating VisonPro VisionOS Apps and the required Tools

Understanding the Vision Pro Ecosystem and its features

At the heart of the Vision Pro experience is the blend of virtual reality (VR) and augmented reality (AR), powered by Apple’s cutting-edge M2 chip and a specialized R1 chip. These components work in harmony to deliver unparalleled performance and immersive experiences, tracking your movements and rendering captivating virtual environments.

Understand its most important and unique features, such as:

Eye, Hands, and Voice based gesture commands:So whichever VisionPro app idea that you are contemplating to create should completely exploit these cool features.

Virtual Avatars and 3D Facetime: Virtual avatar in VisionPro universe are going to more realistic and so as the video calls. We also think of a scenario where an AI avatar of yours takes a meeting on your behalf while you physically take another meeting and the possibilities are endless.

Immersive-ness Control:VisionPro users can increase or decrease the level of immersiveness as per their choice, so your App should be compliant to the same.

Transparent Display: As VisionPro is a mixed reality spatial device, the display is actually transparent as it goes hand in hand with the reality. So your UI/UX design must adhere to this fact and in most of the cases a minimal design will turn out to be the best design because everything else will be taken care of by the real world.

02. Getting Started with visionOS App Development

The gateway to creating apps for Vision Pro is visionOS, Apple’s bespoke operating system tailored for spatial computing. This environment is your canvas, allowing you to merge digital creations with the physical world seamlessly. To set sail on this development journey, you’ll need a Mac running macOS Monterey or newer, the latest version of Xcode, and the Vision Pro developer kit. At Agicent’s VisionOS App Development Company, we’ve all the required infrastructure, team, testing devices and some more. You just have to tell us about your project, and we take care of the rest.

03. Ideation of VisionPro VisionOS App

An entrepreneur or startup or a brand should explore all the possibilities a spatial VisionOS App can achieve on this device. Do a market analysis, competitive analysis, go back to the history where web apps exploited mobile capabilities and a new market was emerged, so similarly think of what additional capabilities mobile apps can offer if they are ported onto visionPro devices.

We think of scenarios in the industries like healthcare where preventive healthcare and telemedicine apps can be created for VisionOS with spatial capabilities, or in an industry where there are plenty of machines and a VisionPro Maintenance App can tell the supervisor about health, maintenance schedule, warranty of the machines just by looking at them, or think of a real estate app where you just wear your visionpro device and see which of the properties in front of you are up for sale or rent and so on.

It is always beneficial to have a industry or subject matter expert on board while ideating for an app for that particular industry, however there are some low hanging fruits that anyone can achieve simply by scaling the existing apps with the spatial mixed reality features for the visionpro device.

We as a VisionOS App Development Company provide you consulting service even before development in figuring out the right features, UI/ UX and target userbase for your VisionOS App idea.

[fandroidrobotheadcanons]

Because Fandrew and Fandroid are similar in build, ADHOC would run experiments on Fandrew so they could get a good estimate on how much damage Fandroid could handle and what kind of conditions he could withstand, meaning Fandrew lacks the ability to have a proper moral compass and is apathetic towards the pain of others because he assumes everyone else has gone through similar experiments and are able to brush off any kind of damage like him

Fandrew does not have a proper grasp the concept of pain!!! He thinks that's a regular feeling that you experience like being tired because ADHOC basically told him during endurance tests that he's only in real pain if he knows he's on the verge of getting irreparable damage, and the closest thing he go to that was when Fandroid became the new golden child and realized ADHOC saw Fandroid as a superior version of him (Yowchie! Emotional pain ;() He just assumes anyone that is aggressive towards him is giving him another endurance test!! He does not recognize anything as harmful behavior because ADHOC is anti-mental health awareness!!

Rust Compiler Performance Triage

Much noise in benchmarks this week, which makes it hard to tell what the real improvements were and what they were due to. A query cache change (PR #107667) is part of the story. In addition, much improvement was reaped from the change to not deaggregate MIR (PR #107267). Finally, microoptimizing fold_ty (PR #107627) yielded a small improvement to a broad set of benchmarks.

Triage done by @pnkfelix. Revision range: a64ef7d0..e4dd9edb

Summary:

(instructions:u) mean range count Regressions ❌ (primary) 2.4% [0.3%, 18.8%] 18 Regressions ❌ (secondary) 1.8% [0.2%, 4.1%] 21 Improvements ✅ (primary) -1.0% [-3.2%, -0.3%] 88 Improvements ✅ (secondary) -4.0% [-13.1%, -0.1%] 47 All ❌✅ (primary) -0.4% [-3.2%, 18.8%] 106

Import Customs Clearance Explained

When customs clearance is associated with imported goods, it is known as import customs clearance. The process involves examination, evaluation, and appraisal of goods that aid the custom authorities to determine how much duty is to be charged and also assess the goods against any illicit import. Let’s take a closer look at major intervention points of the import customs clearance process.

Bill of Entry - The bill of entry is the first major step in the entire import customs clearance process flow. It is also termed as Shipping Bill. It is a statement that is prepared by the shipper mentioning the nature and value of goods that are to be imported. This document is presented to the Customs House and is supposed to be filed by the importer in four copies namely original and duplicate which are meant for customs, third copy for the importer himself, and the fourth copy for the bank for making remittances, if any. In the EDI way, no Bill of Entry is to be filed as the system generates it. However, the importer needs to file a cargo declaration with particulars essential to process the entry of the goods for customs clearance.

On the contrary, in the non-EDI way, along with the bill of entry, the following documents are also required:

●      Signed invoice

●      Packing list

●      Bill of Lading (BL)/Delivery Order (DO)/Airway Bill (AWB)

●      Duly filled in GATT declaration form

●      Importer/CHA’s declaration

●      License

●      Letter of Credit/Bank Draft

●      Insurance document

●      Import license

●      Industrial license

●      Test report (for chemicals)

●      Adhoc exemption order

●      DEEC book/DEPB in original

●      Catalogue/technical write-up/literature for chemicals, machineries, or spare parts

●      Split up value of spares, machineries

●      Certification of origin

●      Declaration for no commission

Bill of Entry Amendment - After the submission of documents, if mistakes are identified, amendments are carried out in the Bill of Entry with Deputy/Assistant Customs Commissioner’s approval.

Green Channel facility - Major importers are entitled to green channel facility under which goods are cleared without routined examination. At the time of filing Bill of Entry, they are required to make a declaration in the declaration form. Although the appraisement is done abiding the normal procedure but no physical examination of goods takes place.

Duty payment - Import duty can either be paid in the designated banks or through TR-6 challans.

Prior entry for Bill of Entry - There is a provision in section 46 of the Customs Act for faster clearance of goods. This allows Bill of Entry to be filed before the arrival of goods. This Bill of Entry has a validity of 30 days from the date of presentation.

Specialized Schemes - If goods are imported under specialized schemes such as EOU, DEEC, etc, the importer must sign bonds with the custom authorities.

Bill of Entry for Warehousing/Bond - If goods are cleared for warehousing purposes, a different kind of Bill of Entry is used. However, the assessment of this type of Bill of Entry remains the same as usual Bill of Entry.
