How to kill a company.

February 22, 2023

Followers of Elon Musk's career understand that, while he is most assuredly obscenely wealthy, a business genius he ain't. Stock in his electric car company, Tesla, has dropped a stunning 26% thus far in 2024. And the year has only begun. His SpaceX venture isn't faring much better, either. Its attempt at a rocket launch last November ended with the spacecraft exploding minutes into the test flight. It was the sixth such failure for the space technology company.

So when Musk bought the social media platform known as Twitter in October 2022 for the announced price of $44 billion (after considerable legal wrangling as Musk tried to wriggle out of the deal), many wondered how long it would take him to destroy the company. Turns out not that long.

Having extravagantly overpaid for Twitter, Musk set about trying to recoup by extracting every dime he could from the business. His first act was to cut costs by firing over 80% of Twitter's staff, reducing it from just under 8,000 to around 1500 employees. In particular, this included content moderators whose job it was to battle disinformation on the site. As a result, the platform became flooded with phony bot accounts, conspiracy theorists and previously banned users (i.e., right-wing trolls, anti-Semites and other hate-mongers). In response, hundreds of major advertisers reduced or halted their ad spending on the site by January 2023.

Twitter’s original verification system was based on the premise that it had evidence the accounts it identified with blue check marks belonged to the actual people claiming them and that those were people or organizations of some importance. Musk did away with all that by selling blue checks to anyone willing to shell out $8 a month — an offer taken up by less than 1% of the app's actual users.

Finally, in what was possibly the worst re-branding decision ever, Musk decided to ditch the globally known Twitter name and relabel the app X (a letter he seems obsessed with). As the technology news site Engadget reported,

Musk killed Twitter by slowly making it useless for those who relied on it for real-time information, by choking off conversations from those not willing to pay, by flooding users’ timelines with spammy blue-check sycophants and renaming the company X.

Recently, a Pew Research study asked current and recent X users how likely they are to use the platform a year from now. A quarter of the respondents said not very or not at all. So congrats, Elon. You've euthanized your enterprise.

So without getting into what a garbage bag of a human Elon Musk is, and also how he isn't smart, doesn't have an engineering degree, isn't an inventor, etc etc...

i see the headline that his neuralink brain chip has been implanted into the first human brain. (NPR) (Al Jazeera)

OK and without getting into the dodgy ethics of this even apart from all the dead monkeys, like a LOT of dead monkeys... (like holy shit it's at least 12 monkeys and over 1,500 animals including sheep, pigs, and monkeys) (like OMG HOLY SHIT they don't even keep precise records on the numbers of animals tested and killed?? this is monstrously immoral) (source)

left unchecked i worry this is going to end like Dollhouse. (a 15 year old TV series you should watch, which doesn't have any monkeys) and why is Musk doing all this? that answer is in The Fall of the House of Usher (a recent streaming series you should watch, although there are definitely monkeys in it).

(semi related on the recommendation of my dentist i bought an electric toothbrush. damn thing wants to be bluetooth paired to its app. an app!! it's a fucking toothbrush it doesn't need to be connected to jack shit.)

anyways, everything Musk touches goes to shit (or goes up in flames) so even if there was some timeline where this is a good use of technology and it helps people - he's going to run the company poorly and it will hurt people. just like it's already hurt a ton of animals. where is the independent verification of their claims that the human is "recovering well?" where is the oversight?

NASA completes spacecraft to transport, support Roman Space Telescope

The spacecraft bus that will deliver NASA’s Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing.

Now that the spacecraft is assembled, engineers will begin working to integrate the observatory’s other major components, including the science instruments and the telescope itself.

“They call it a spacecraft bus for a reason — it gets the telescope to where it needs to be in space,” said Jackie Townsend, the Roman deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But it’s really more like an RV because it has a whole assortment of functions that enable Roman to accomplish its scientific goals while out there too.”

Those goals include surveying wide swaths of the universe to study things like: dark energy, a mysterious cosmic pressure thought to accelerate the universe’s expansion; dark matter, invisible matter seen only via its gravitational influence; and exoplanets, worlds beyond our solar system.

The mission’s science wouldn’t be possible without a spacecraft to transport the telescope, point the observatory toward different cosmic targets, provide power, communicate with Earth, control and store instrument data, and regulate Roman’s temperature. Nearly 50 miles of electrical cabling are laced throughout the assembly to enable different parts of the observatory to communicate with each other.

The spacecraft will also deploy several major elements that will be stowed for launch, including the solar panels, deployable aperture cover, lower instrument Sun shade, and high-gain antenna. It’s also responsible for collecting and beaming down data, which is no small task for a space observatory that will survey the cosmos like Roman will.

“Roman will send back 1.4 terabytes of data per day, compared to about 50 to 60 gigabytes from the James Webb Space Telescope and three gigabytes from the Hubble Space Telescope,” said Jason Hylan, the Roman observatory manager at NASA Goddard. “Webb’s daily downlink is roughly comparable to 13 hours of YouTube video at the highest quality while Roman’s would amount to about 2 weeks.”

A Goddard Grand Slam

This milestone is the culmination of eight years of spacecraft design work, building, and testing by hundreds of people at Goddard.

“Goddard employees were the brains, designers, and executors. And they worked with vendors who supplied all the right parts,” Townsend said. “We leaned on generations of expertise in the spacecraft arena to work around cost and schedule challenges that arose from supply chain issues and the pandemic.”

One time- and money-saving technique the team came up with was building a spacecraft mockup, called the structural verification unit. That allowed them to do two things at once: complete strength testing on the mockup, designed specifically for that purpose, while also assembling the actual spacecraft.

The spacecraft’s clever layout also allowed the team to adapt to changing schedules. It’s designed to be modular, “more like Trivial Pursuit pie pieces than a nesting egg, where interior components are buried inside,” Townsend said. “That’s been a game-changer because you can’t always count on things arriving in the order you planned or working perfectly right away with no tweaks.” It also increased efficiency because people could work on different portions of the bus at the same time without interfering with each other.

The slightly asymmetrical and hexagonal spacecraft bus is about 13 feet (4 meters) wide by 6.5 feet (2 meters) tall and weighs in at 8,400 pounds (3,800 kilograms).

One reason it doesn’t weigh more is that some components have been partially hollowed out. If you could peel back some of the spacecraft’s panels, you’d find superthin metallic honeycomb sandwiched between two slim layers of metal. And many of the components, such as the antenna dish, are made of strong yet lightweight composite materials.

When the spacecraft bus was fully assembled, engineers conducted a comprehensive performance test. Prior to this, each component had been tested individually, but just like with a sports team, the whole unit has to perform well together.

“The spacecraft passed the test, and now we’re getting ready to install the payload –– Roman’s instruments and the telescope itself,” said Missie Vess, a spacecraft systems engineer for Roman at NASA Goddard. “Next year, we’ll test these systems together and begin integrating the final components of the observatory, including the deployable aperture cover, outer barrel assembly, and solar panels. Then we’ll finally have ourselves a complete observatory, on track for launch by May 2027.”

How to Do a Load Bank Test on a Generator?|EMAX Load Bank

Generators are critical assets for businesses and homes, providing essential backup power during outages. To ensure that a generator will perform as needed during an emergency, it is crucial to conduct regular maintenance and testing. One of the most effective ways to test a generator's performance is through a load bank test. This comprehensive guide will walk you through the steps of performing a load bank test on a generator, ensuring optimal performance and reliability.

What is a Load Bank Test?

A load bank test involves using a device known as a load bank to simulate electrical loads that the generator might encounter during operation. The test ensures the generator can handle its full rated capacity and helps identify any issues that could affect performance. Load bank tests are essential for maintaining the health of standby generators, ensuring they can provide reliable power when needed.

Why Perform a Load Bank Test?

Performing a load bank test has several benefits:

Ultimate Guide to PCB Testing Methods: Ensuring Quality and Reliability in Your Circuits

In the electronics sector, Printed Circuit Boards (PCBs) are the life-lines of virtually all gadgets that are in use in the modern society. From humble home appliances to gigantic industrial equipment, PCBs are the skeletal framework of hardware organization and connection of circuit elements. It is vital to guarantee the quality and dependability of these fundamental parts – thus enters PCB testing methods. It is our hope that this extensive hand will help identify the most suitable test strategies for PCB testing, why these techniques matter, and how to maximize your circuits’ functionality.

Introduction

Firstly, an increase in the capability of different electronic devices leads to higher necessary requirements to the PCBs used in their production. Performing tests on the PCBs is an essential step in the manufacturing process done to confirm that a given board performs as a unit to the expected levels. This guide aims at explaining various techniques of PCB testing with a view of having a better understanding on how to achieve quality and reliability on the circuits.

Why PCB Testing is Crucial

PCB Testing When it comes to the potential defects on PCBs, there are shorts, opens, and some component placements. They can cause device failure, decline in performance level, and sometimes also pose safety issues. Through high-quality testing regimes, it becomes easier to address problems before they reach the customer, and thus manufacturers will have reliable and efficient products. Key reasons for PCB testing include:

Detecting Manufacturing Defects: Solder bridges, missing and placed in wrong position components, all can be detected in the initial stages easily.

Ensuring Functionality: Ensuring that the PCB does what is wanted and needed when it is in use, and under several conditions.

Quality Assurance: Ensuring that the business meets industry standards, and what clients require of them.

Cost Efficiency: Decreasing the likelihood of rework and recall by identifying possible defects before they get to the customer.

Types of PCB Testing Methods

These are the types of PCB Testing Methods:

Visual Inspection

Technique one as also referred to as the VI or visual inspection is the simplest and basic type of testing done on PCBs. The technique entails inspecting the board with naked eyes for some of the common faults including solder bridges, missing parts, and misalignment issues.

Automated Optical Inspection (AOI)

AOI employs cameras and software algorithms to check PCBs for defects and performs the inspections singly. This method of inspection is far more efficient than the manual inspection and simultaneously versatile enough to identify numerous problems.

X-ray Inspection

Some functions which include examination of features of BPCs that could not be easily inspected include solder joints under components through x-ray inspection. It is especially effective in inspecting defects in BGA (Ball Grid Array) and other various packages as well.

In-Circuit Testing (ICT)

ICT entails applying different voltage across the PCB to checks on the electrical characteristics of the needy part and connections. The use of this method is highly recommended for the identification of functional problems and verification of the circuit’s goodness.

Functional Testing (FCT)

Functional testing evaluates the effectiveness of the PCB pointing to the fact that it can be tested when placed in use. This method enables the certification of that the PCB works as expected under actual environment.

Flying Probe Testing

In flying probe testing, the probes are moved around to test the electrical properties of the created PCB. Lower to medium volume production runs can be made easily by using this technique; hence it is advantageous in this regard.

Boundary Scan Testing

Boundary scan testing also called as JTAG testing extends test circuitry into all the components for testing the connections between them. Although, this method is very efficient for identifying connection problems and faults.

Burn-In Testing

Burn-in testing puts the PCB in a state of operational stress for a long time to capture early-life failures. This aspect makes the method reliable for the long term since it is likely to identify problems that may occur when the equipment is in use for a long time.

Detailed Analysis of Each Testing Method works

These are the detailed analysis of each testing method works:

Visual Inspection

Pros:

Simple and low-cost

Determined to be a system for the reporting of noticeable defects as soon as they are observed.

Cons:

Time-consuming for complex boards

Limited to visible defects

Automated Optical Inspection (AOI)

Cons:

Expensive equipment

Requires skilled operators

In-Circuit Testing (ICT)

Pros:

Thorough electrical testing

High fault coverage

Cons:

Requires custom fixtures

Not for all the boards or servers that you wish to build.

Functional Testing (FCT)

Pros:

Ensures real-world performance

Detects system-level issues

Cons:

Time-consuming

The mathematical test object can involve complex arrangements of test configurations.

Flying Probe Testing

Pros:

Flexible and adaptable

Cost-effective for small batches

Cons:

Slower than ICT for big volumes

Applicable only when the board is specially designed

Boundary Scan Testing

Pros:

Interconnections have high fault coverage.

Said; No need to have physical access to the test points

Cons:

Requires boundary scan-enabled components

Complex setup

Burn-In Testing

Pros:

Identifies early-life failures

Ensures long-term reliability

Cons:

Time-consuming and costly

Perhaps stressful to the board

Choosing the Right Testing Method

The choice of the appropriate method of PCB testing can be influenced by several factors such as the level of complexity of the PCB and the numbers of boards to be tested as well as the actual costs of the testing process and other features. Consider the following when choosing a testing method:

Board Complexity: Great board densities or component placement can be a determinant as to whether one needs AOI or X-ray inspection.

Production Volume: Applications that are characterized by high volumes can be easily facilitated by ICT while the low to medium volume applications may require flying probe testing.

Budget: Both manual inspection and AOI are favorable for various production volumes, while X-ray and ICT are more expensive at the beginning.

Specific Requirements: There are two types of the test, namely Functional Test and Burn-In Test that should be made so as to attain the long term reliability in applications that are critical.

Best Practices for PCB Testing

Using the best techniques in testing PCBs increases the quality and reliability of the circuits that you are working on. Here are some key practices to follow:

Early Testing: It is recommended to carry out the tests when the product is still in its design and manufacturing phase so that problems can be noted earlier before they reach a very catastrophic level.

Automate Where Possible: Use method such as automation to reduce the time and improve on the quality of the testing.

Regular Calibration: It is necessary to check if all the testing equipment used for calibration are accurate.

Comprehensive Coverage: This way, you will be able to ensure that there are no defects that are not tested as the best testing approach combines all types of testing methods.

Document Everything: Ensure that you keep records of the tests performed, the results obtained, as well as any measures taken to correct the breaches.

Common Challenges and How to Overcome Them

These are the common challenges and how to overcome them:

False Positives/Negatives

Automated testing methods maybe good some times, they give you the results that are either positive or negative and this will lead to unnecessary rework or more alarming leaving critical defects unfound. In order to avoid this, make sure that testing algorithms and testing equipment are updated and fine-tuned from time to time.

Component Access

Some of the testing techniques involve handling parts of the circuit and with high density board this can be very difficult. Some of the ways in which testbench implementation can be avoided are as follows Boundary scan testing and X-ray inspection.

High Costs

Some form of testing such as X-ray and ICT testing is often very costly. The effectiveness must come with reasonable prices; try to combine some of the mentioned approaches to cover all the aspects without spending too much money.

Future Trends in PCB Testing

About the future, it can be stated that its trends will be in fact linked to the tendencies in technologies and expectations towards ever higher quality and quantity of tested PCBs. Key trends to watch include:

AI and Machine Learning: Using of intelligence algorithms and machine learning in testing algorithms to enhance the efficiency and the minimization of false negative or false positives.

IoT and Smart Manufacturing: Higher testing flexibility and opportunities for the continuous test process supervision.

Advanced Imaging Techniques: The need for better techniques that would enhance the detection of defects within a printed circuit.

Environmental Stress Testing: More focus in the testing of PCBs under different environmental pressures in order to improve on its longevity.

Conclusion

Quality and reliability of packaged circuits have to be maintained to contribute positively in any electronic equipment. This paper seeks to explain the common testing techniques for PCB so that PCB manufacturers are able to test and see if they are free from defects and if they are functional. This ultimate guide will give you a full insight on the available options in PCB testing that will enable you make the best decision that will give you perfect circuits.

The aim is to help you understand how to attain the best quality of PCBs, what methods are worth following, and what trends drive future improvements, thus contributing to the quality of the final electronic products and, consequently, consumer satisfaction.

[recurring-polynya]

you know. I think it would be absolute hilarious if rukia turned out to. you know NOT be hisana’s sister and instead there was just a insane resemble between them. it happens sometimes.

….actually, the more I think of this, the more not-hilarious it derails to be. ITD BE A DISASTER-ANGST (but also really hilarious). but seriously, I wonder if byakuya just saw rukia and thought she was hisana’s sister immediately from the resemblance and didn’t doubt at all………

what if rukia didn’t look like hisana at all. how were they trying to look for her. considering hisana left her when she was just a babe or like, smol.

just some thoughts. ❤️

The verification of Rukia and Hisana's sisterhood is one of those things that I tend to assume is, as we say in mathematics, "a solution exists and is left as an exercise to the reader," which is to say, I assume there is some sort of kidou-based blood test, or that they have similar reiatsu or some that there do exist some sort of soul-sorting records that could place Rukia and Hisana arriving in Inuzuri at the same time (not accessible to Rukongai riffraff, but all doors are open to the head of the Kuchiki), and that Byakuya was not simply depending on anime same-face-sibling-syndrome.

[This does not have anything to do with anything, but the timeline of Hisana and Byakuya's marriage, which does not reconcile with the timeline of Renji and Rukia's friendship and separation, which absolutely does not reconcile with Rukia's claim in the first issue that she is "ten times Ichigo's ago." I still maintain she was lying to Ichigo, because she doesn't know how humans age, but I feel this lends further credence to @bleachbleachbleach 's theory that time runs slower in the Rukon, which I vastly prefer to the idea that it took Rukia 90 years to age from a baby to a teen. Well, maybe it did take 90 years, but the value of a year is variable]

Back to your question, what if??? and I am sure this is not the answer you were expecting, but after contemplating it, I am absolutely delighted to declare IT DOESN'T MATTER, EVEN A LITTLE BIT.

Over the last few years, probably since the Rey's parentage debacle in the latest Star Wars Trilogy, I have really struggled with how I feel about bloodlines in fantasy, because on one hand, they are gross, but on the other, this sort of thing features in a lot of stories I like. Bleach, in particular, dances around this issue a lot, particularly in Ichigo's case, but I think it's very relevant to this discussion. Then, recently, I happened to read this absolutely fantastic quote from author Ted Chiang (emphasis mine):

[Chiang] gave two stories: one where gold could be created for cheap by anyone and another where only a few people had the ability.

The difference between the two examples is the importance of the practitioner. The second example — found in the genre of fantasy — depends on the individual, with the universe choosing a particular person for a particular reason. The person may have an innate gift, or a purified soul,  for example. Reasons could also include good intentions, hard work, intense concentration or personal sacrifice. 

The first, which he said is more reminiscent of science fiction, requires none of these.

“None of these things are true of scientific phenomena,” Chiang said. “When you pass a magnet through a coil of wire, electric currents flow, no matter who your parents are, whether your intentions are good or bad. You don’t have to concentrate power or offer a sacrifice in order for a light bulb to turn on. Electricity doesn’t care.”

In fiction, magic typically requires individuals and responds differently to each one. 

“Magic is evidence that the universe knows that you’re a person,” Chiang said. “Magic is an indication that the universe recognizes that people are different from things and that you are an individual who is different from other people.”

This got me really thinking about the differences between "bloodline" and "fate," and "what actually happens", and also "character" vs "role", one of my very favorite dichotomies in storytelling. In very simple stories, a character is fated to do a thing because of their ancestry and they do it. This is okay in ur-stories, like folktales and legends, but it's pretty reductive in modern stories.

Take Ichigo, for example. He's got this absolutely wild bloodline, which is the source of his powers and it seems like it is what defines him as the savior of the Bleach universe, except that a lot of his stories involve a villain trying to get him to destroy things because it's what he's born to do, and he generally rejects that premise, and does what he wants (which is to protect his precious friends).

Among characters in Bleach, Byakuya is firmly on the side of "bloodline = destiny." He is the culmination of generations of one family acquiring wealth and resources and power in Soul Society and constantly tells people (Renji, Ichigo) that they cannot hope to compete with that. His one great sin was marrying a woman with terrible bloodline and then, ironically, he has to go adopt Rukia because she's connected to Hisana by that same bad blood.

This is the really important part: Hisana is bound to Rukia out of obligation. Rukia is connected to Hisana by blood. That's it. Rukia has no memory of Hisana even existing. Hisana knows nothing about Rukia as a person. I will pound my shoe on the table all day that "Rukia" is a name that Rukia took upon herself and that Hisana never even heard it. Their sisterhood is a technicality.

It literally doesn't matter whether Rukia was Hisana's sister or she was just some random kid from Inuzuri, the outcome is the same.

Aside from the physical resemblance, which is used as an explanation, there is not one moment in Bleach where Byakuya implies that Rukia has a single quality in common with Hisana. They have no shared powers. There is no quality of "being Hisana's sister" that shapes Rukia, aside from it being the catalyst for the adoption. Even in the very important New Year's filler episode, where Byakuya asks Rukia to perform a dance that Hisana did once, we are told nothing about how Hisana did, or how her dance was received, or how she felt about it.

I love to read the myriad of interpretations of Hisana. Sometimes, she was a trained courtesan who was skilled in dance and navigating the social tripwires of Seireitei high society. I've read others where she is a naif, plucked straight from Rukongai and plopped into Kuchiki life as a fish out of water. She was a shinigami. She was skilled at sewing and handicrafts. She was a thief.

Hisana is not a character. Hisana is a literary cipher, a placeholder for the reader's own projections. She is a role. She is "Byakuya's dead wife." She is "Rukia's long lost sister."

Rukia and Byakuya are not ciphers. They are characters and it is their relationship that we see, as they go from strangers trying to act out their assigned roles, to siblings who (literally) count losing each other as one of their greatest fears. According to this post, Kubo notes in the 13 Blades artbook that Byakuya was designed to look like a male counterpart to Rukia. They are both stoic, serious, and driven, but also complete stunt queens. The circumstances of their meeting were pre-determined, but their siblinghood is their own. It's something they created.

I think that it might be an interesting story if it somehow came to light after the fact that Rukia was not Byakuya's sister, because it would force him to say out loud that he loves her because he loves her and not because of duty, but by late canon, I really don't think he would have a problem doing that. If it turned out that Hisana's real sister died in the Rukon, I think they would have an awkward cup of tea over it and then never speak of it again. If the real sister showed up, I think Byakuya would just adopt the new one and if anyone asked him about Rukia, he would just be like, "She is a Kuchiki now, you cannot un-Kuchiki someone."

Now the truly most delightful twist on this would be a t4t Renruki scenario where after the truth falls out, Rukia is like, "that's a cool story, bro, but you shoulda said something earlier, there was no way I was anyone's baby sister" and then it turns out the baby was Renji.

When he first takes him in as Robin Bruce does a very thorough physical exam of Tim, including full body scans — scans which he then uses to print a perfect silicone replica of Tim for him to use, or maybe even makes west-world style android copy of Tim, with memories he’s designed to make this new version think he’s always been Bruce’s, his Daddy’s, sex slave?

👀👀👀👀 i love bruce using "duty" and the "job" as an excuse to take advantage and be a creep because the plausible deniability of it all is so good!!!!!! bruce tells tim that the exam is needed so that his file for 'identity verification' can be begin. it's a file that needs to be used anytime that tim's identity is called into question so bruce needs to cover ALL his bases. hair samples from different parts of his body to identify the exact color of his hair, coarseness from different areas, and general spread. skin samples and nude photos because sometimes hyperpigmentation can occur. a mold tim's mouth, vagina, and anus. it may be humiliating but its necessary! finally is the full body scan where tim lays down on some operating table thing and gets scanned by about a million lasers that create a perfect computer model of tim and his insides like his organ placement and vocal cords. tim is hooked up to a machine to measure his brain waves when certain stimuli hit him: feathers, electrical shocks, burns, a force that causes bruising, papercuts, sand, dirt, water, clay. the most humiliating part for tim was when he was asked to masturbate while a heart monitor tracked his heart rate at rest, during exercise, after exercise, while in pain, and while in pleasure.

bruce is incredibly thorough and tim tries his best not to say anything or react when bruce's gloved hands measure and squeeze tim's flesh in a clinical manner. tim had nearly lost his composure when bruce pressed a finger into his cunt until it was uncomfortably deep and the tip of bruce's finger was pressing against tim's cervix. bruce always carries a clinical and detatched sort of interest, running tim through all theses tests and trials like it's nothing- like tim would be the crazy person to react in any way.

eventually, tim's examination comes to an end and he can breathe a sigh of relief knowing that he only has to endure this one time a year.

only that tim is blissfully unaware that this is the first time bruce has ever created such scans . bruce knows tim will never bring this up to alfred or dick or anyone because he's embarrassed and teenagers are easily made insecure. which bruce was banking on because the moment he'd met tim he felt an instant, intense attraction. which horrified him, disgusted him even. tim was so young, barely in high school. bruce had never found an attraction to anyone so young before but with tim...it was almost like a switch went off. like something in his brain was immediately focused on the pink fullness of tim's lips, the burgeoning slope of his breasts, the soft puffiness of his cunt. bruce had clenched his hand the entire time he parted tim's wet, sticky, pink folds and measured the depth, feeling out every ridge inside that little pussy. bruce had needed to bite down on his tongue when he squeezed tim's little baby breasts and control his breathing when he watched tim undress and peel off his undergarments. bruce can't act on his feelings, he can't touch or think of tim in such a way.

it could ruin their partnership dynamic, it could traumatize tim, it could traumatize bruce. but....bruce can't help the way he feels, the way his hands and cock are always too aware of tim. he messes up anyway because one night he can't resist and starts masturbating to the thought of fucking into tim's little pussy, listening to his moans. the fantasy soon doesn't become enough and bruce recognizes the pattern of escalation in his behavior. first it will be thoughts, then it will be pictures, then he'll be actually touching tim and bruce doesn't want to do this to tim. tim trusts bruce, has faith in him and looks up to him. how hurt would tim be to know that bruce thinks of tim in such a sexual and objectifying manner?

so bruce can't do this to tim, his partner, his child. but he also can't...just ignore the pool of arousal that fills his gut just at the sight of him. bruce needs an outlet, a way for his brain to differentiate between tim who it's not acceptable to harbor these feelings for and...the idea of tim who it is.

bruce knows, has met, and fought numerous humanlike robots and androids. red tornado, toyman, amazo- all are prime examples of creations and people who had near perfect configurations to the point they were more human than machine. and bruce, being part of the justice league, had access to their schematics. bruce may not be the greatest robotics scientist in existence but he's one of the very few who could craft such a sophisticated...sex toy. it's not a person, no matter what the appearance may suggest, it was metal and silicone and artificial in every way. even if the android will contain tim's memories from the brain scans bruce collected. memories that bruce will curate and edit. make tim less...curious, more willing to accept facts as they are presented to him. make him wary to anyone but bruce. make him happy to be contained. happy to serve bruce. happy to fuck bruce because it brings him the greatest pleasure he's ever felt. have him love bruce. bruce needs to make edits to tim's personality to make him more malleable, he needs to shift his memories around so that tim thinks of bruce as a savior. that tim came onto him first and that bruce was just reciprocating and bruce just loved it so much and it made them both so happy that it's what they spent every waking moment doing. make sure tim never thinks to question why he doesn't eat, why he doesn't sleep, or drink, or why he never gets pregnant from their encounters.

it takes months for bruce to complete his "side project" that he has stored away in a secret underground level of the cave. not because it takes that long because it takes that long to get it right, to get tim just the way he likes him. in order to make sure his brain never mixes them up bruce gives tim a slightly longer haircut and piercings in his ears where he hands two little tags like tim is a milking cow.

the night that bruce decides to use his new toy he makes sure it's on a day where tim goes to visit dick in bludhaven. bruce insists alfred accompany him, telling him it's bring him peace to know he's with tim and also so that alfred will be able to see dick for himself. bruce waits a half an hour once they've left to go down to the cave and turn on tim. tim's eyes blink open like he's just woken up, accompanied by a big yawn and a drowsy look around the room. when he catches sight of bruce he immediatly perks up, eyes shining in happiness as he squirmed on the king size bed that bruce set up on the level.

bruce feels arousal immediatly settle in his gut as tim's thighs part and reveal the wet, pink slit that bruce had spent the most amount of time on. bruce is tugging off his clothes with the ferver of a teenager as tim giggles and bounces softly on the bed calling out for his 'daddy' and that he 'missed you!'. bruce's cock is so hard at the sound of tim's voice. with the scan of his vocal cords as well as plenty of recordings bruce was able to write a perfect program for tim's voice.

bruce is insatiable for hours as he fucks his little sex doll that moans and is bounced up the bed by him, wiggling little hips back to meet his thrusts as bruce pins him down and fucks his little red cunt until it's trembling around him. bruce made sure to code tim to have an orgasm within three minutes of penetration. he likes having a cunt tighten around him while he was still hard. tim ended up cumming three times before bruce groaned and stuttered his thrusts into tim's little cum dump hole (literally what bruce has it labeled in his blueprints). bruce spends a few minutes resting before having tim's cute little mouth take him in and begin gently lapping at his cock to clean him off and get him hard again. when he's finally suitably aroused he has tim ride him, gripping his soft hips and occasionally snapping up into the tight baby cunt around him. tim's entire body turns pink with arousal, especially his bouncing tits that bruce liberally kisses and sucks on.

bruce knows he should be horrified with the depth of his depravity, he knows he never should've done this- literally objectified tim to satiate his sexual attraction. he knows that this is a level of twisted he's never reached before. but he can't help it. as bruce fucks his tim, his little sex toy who calls him daddy and begs for his cum and for bruce to use him, he can't find a single regretful bone in his body.

not one.

RoHS Certification in Bangalore: Promoting Environmental Responsibility in Electronics

RoHS Certification in Bangalore - The Restriction of Hazardous Substances (RoHS) Directive, originally introduced by the European Union, is designed to limit the use of certain hazardous materials in electrical and electronic equipment (EEE). For companies in Bangalore involved in the design, production, or export of electronics, obtaining RoHS certification is essential for both regulatory compliance and environmental responsibility. RoHS certification helps ensure that electronic products meet global standards, safeguarding human health and the environment by reducing harmful substances.

This blog explores the importance of RoHS certification in Bangalore, focusing on implementation, services, and the audit process.

RoHS Implementation in Bangalore

Implementing RoHS compliance in Bangalore requires businesses to eliminate or significantly reduce the use of specific hazardous substances in their products. These substances include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). By adhering to these restrictions, companies can ensure that their products meet environmental regulations in both local and international markets.

Here are the key steps for implementing RoHS certification in Bangalore:

Product Evaluation: The first step in RoHS implementation is to assess the materials and components used in the manufacturing of electronic products. This involves identifying any hazardous substances present in the product’s design and supply chain.

Substitution of Hazardous Materials: Once the hazardous substances are identified, manufacturers must replace them with safer alternatives. For example, lead-free soldering techniques and non-toxic flame retardants can be used to comply with RoHS requirements.

Supplier Compliance: In many cases, suppliers play a crucial role in RoHS compliance. Manufacturers in Bangalore must work closely with their suppliers to ensure that all materials and components meet RoHS standards. This may require obtaining material declarations and certifications from suppliers.

Product Testing and Documentation: RoHS compliance involves rigorous testing of products to confirm that hazardous substances are below the permitted thresholds. Testing can be performed through specialized laboratories that provide chemical analysis and verification. Additionally, companies must maintain detailed documentation that demonstrates their products’ compliance with RoHS regulations.

RoHS implementation in Bangalore helps businesses reduce their environmental footprint, enhance product quality, and ensure regulatory compliance in global markets, particularly the European Union and other regions with strict environmental laws.

RoHS Services in Bangalore

For businesses in Bangalore seeking RoHS certification, a range of services is available to guide them through the process. These services are designed to help companies achieve compliance while minimizing disruption to their production processes.

Consulting Services: Several consulting firms in Bangalore specialize in RoHS compliance. These consultants offer expert guidance on how to restructure product designs, manufacturing processes, and supply chains to meet RoHS requirements. Consulting services typically include gap analysis, where companies’ current practices are assessed against RoHS standards, and recommendations for achieving compliance.

Testing and Certification: Accredited testing laboratories in Bangalore provide comprehensive RoHS testing services. These labs use advanced techniques, such as X-ray fluorescence (XRF) analysis and inductively coupled plasma (ICP) testing, to detect the presence of restricted substances. Upon successful testing, companies receive certification that their products meet RoHS regulations.

Training and Awareness Programs: RoHS compliance requires knowledge and coordination across various teams, from procurement to manufacturing. To facilitate this, training programs are available in Bangalore to educate employees on RoHS regulations, compliance strategies, and best practices for material management. These programs ensure that staff members understand the requirements and can contribute to maintaining compliance.

Supply Chain Management: RoHS compliance extends beyond a company’s internal processes to its entire supply chain. RoHS Services in Bangalore providers in Bangalore offer support in managing supplier relationships, verifying material compliance, and maintaining documentation. This helps businesses ensure that all components and materials used in their products meet the necessary standards.

These services provide the necessary support to manufacturers in Bangalore, enabling them to meet global environmental standards and expand their market reach.

RoHS Audit in Bangalore

A critical component of achieving and maintaining RoHS certification is the audit process. RoHS audits ensure that a company’s products are free from restricted substances and that their production processes meet regulatory requirements.

Internal Audits: Before seeking external certification, companies in Bangalore should conduct internal audits to assess their readiness for RoHS compliance. These audits involve reviewing product designs, testing procedures, and supply chain documentation to identify any potential gaps in compliance. Internal audits also provide an opportunity to address any non-conformities and improve processes before the formal certification process begins.

Third-Party Audits: To achieve RoHS certification, companies must undergo a formal audit by a third-party certification body. These audits are conducted by accredited organizations that specialize in verifying compliance with RoHS regulations. The audit process typically involves an in-depth review of product testing results, material declarations from suppliers, and the company’s documentation practices. Auditors also assess the company’s ability to maintain compliance over time.

Continuous Monitoring and Surveillance Audits: RoHS compliance is an ongoing process, and companies must ensure that their products continue to meet regulatory requirements after certification. Certification bodies may conduct periodic surveillance audits to verify ongoing compliance. These audits help identify any new risks, such as changes in materials or suppliers, and ensure that corrective actions are taken as needed.

In Bangalore, several organizations offer RoHS audit services to help companies achieve and maintain certification. These audits provide a thorough assessment of a company’s products and processes, ensuring compliance with environmental standards and reducing the risk of regulatory penalties.

Conclusion

RoHS Registration in Bangalore is a crucial step for electronics manufacturers in Bangalore looking to expand into international markets, especially the European Union. By implementing RoHS standards, companies can reduce their environmental impact, improve product safety, and demonstrate their commitment to sustainability. With a wide range of services available, including consulting, testing, and auditing, businesses in Bangalore can navigate the complexities of RoHS compliance with confidence.

Achieving RoHS certification not only opens doors to global markets but also aligns companies with growing environmental expectations, ensuring a sustainable and competitive future.
