semerda··on Increasing the lifespan of a bulb makes it worse in every other way
Ditto. They barely last 12 mos. This goes for both types: LED Light Chips (Strips) and LED String Lights from various manufacturers.
semerda··on How to make a sliding, self-locking, and predator-proof chicken coop door (2020)
Do you have a rooster to help fight the chaos?
semerda··on ChatGPT o1 tries to escape if it thinks it'll be shut down, then lies about it
AI models are just complex mathematical functions/software and they do not have the capability to access, modify, or control computer systems or networks. There are technical boundaries and I doubt the team at OpenAI just let the AI have full control. This gets filed under marketing fluff.
semerda··on ChatGPT o1 tries to escape if it thinks it'll be shut down, then lies about it
I don't know why you got voted down. I am also skeptical about this bold claim because AI models are just complex mathematical functions/software and they do not have the capability to access, modify, or control computer systems or networks. It's most likely marketing fluff.
semerda··on Gum disease-related bacteria tied to colorectal cancer
Mouthwash kills the good bacteria as well. Better off using chips gum to stimulate natural saliva which helps in reducing bad bacteria.

semerda··on New viruslike entities found in human gut microbes
I like to think of a virus like code. It’s nothing more than a series of instructions in a file that, when executed (by the cell), does something. Is code complex enough to be called life?
semerda··on Working remotely can more than halve an office employee’s carbon footprint
Yet somehow the C02 PPM kept on climbing during Covid era when many worked from home. https://gml.noaa.gov/ccgg/trends/
semerda··on Consensus: Use AI to find insights in research papers
This is great. How is "disputed" calculated? (hopefully not news babble but another paper disputing it?)
semerda··on Higher- than-recommended doses of Vitamin D reduced risk of atrial fibrillation
Step 1. VD3 blood test is a must to determine whether one is deficient. If you work indoors all day there is a high chance you are deficient. Your GP can help you boost it up using 70K IU prescription VD3.

Step 2. Then maintenance. This is all a trial and error and more blood tests. 800 IU / the national recommendation is a joke. Dr. Fauci takes 6,000 IU each day. (see FOIA docs with his email saying what he takes).

I work in tech and take 10 IU each day and have maintained a ~ 60 ng/mL.

Anything over 50 ng/mL shows benefits in fighting respiratory viruses and keeping mortality close to zero. ref: https://pubmed.ncbi.nlm.nih.gov/34684596/#&gid=article-figur...

semerda··on Twitter starts limiting how many tweets you can post per day
A lot of folks aren’t open to change and see change and experiments as frightening yielding biased conclusions.

It’s fine to have opinions but drawing bold conclusions is best done with factual data over a longer time horizons.

semerda··on Cal.com: Open Scheduling Infrastructure
Spot on. A Product (which most engineers can hack together) shouldn't be confused with a Business.
semerda··on Declining quality of consumer-grade products – 2009 fridge compressor autopsy
I heard that one way to check quality is to look at the type of capacitors used on the board.

Capped are cheap and don’t last long (they have a vent on top) and when they blow they spread white residue on the board. The solid capacitors don’t suffer from this, last much much longer but do cost a bit more.

Ps. Maybe someone with more electrical knowledge than I can confirm or debunk this?

semerda··on Coral makes comeback on Great Barrier Reef
Isn't Adani coal mine meant to start commercial-scale coal mining soon? It's right next to the Great Barrier Reef.

"From there, container ships will weave their way through the Great Barrier Reef and out to India and other customers, where the coal will be burned in power stations."

Glad our governments care so much about the environment.

semerda··on Cognitive decline linked to ultraprocessed food, study finds
Salt is a preservative and a key ingredient behind "ultraprocessed products". Are there ultraprocessed products with minimal amount of salt?
semerda··on It’s 2022 and the Magic Mouse still charges from the bottom
Brilliant design. A forcing function to take a break; even tho it's only ~4 times per year it's better than changing batteries every 2 weeks.
semerda··on Moderna’s HIV vaccine has officially begun human trials
I wouldn't call it arbitrary sequence, it's a specific sequence ie. s protein for covid.

Saying that, it's now a known cause of blood clotting in some recipients: https://www.science.org/doi/10.1126/sciadv.abl8213

"chimpanzee adenovirus Y25 (ChAdOx1), human adenovirus type 5 (HAd-V-C5) and human adenovirus type 26 (HAdV-D26) — the scientists found that ChAdOx1 had a strong negative charge, which meant that it attracted PF4, which has a positive charge."

semerda··on Update on Omicron
I’m not talking about inactivation with formaldehyde. If they did that in the viral vector it would disable the delivery mechanism (adenovirus).
semerda··on The truth about turbinates (and sinusitis)
Yikes. Sorry to hear this procedure didn't go as you hoped.

For me I tried radiofrequency at PAMF but it only lasted about a year before my nasal issues returned and I ended up getting septoplasty with turbinate reduction. For me it was mostly a success and to this date I enjoy breathing through my nose with ease. I wonder whether the difference between mine and yours is the volume of turbinate reduction.

Prior to all this I was hooked on Afrin for 2 years. Lost my sense of smell. Bloody oxymetazoline! I finally understood what drug addiction is. It was awful. The rebound effect was devastating which meant I could never get off it. The rebound effect felt like I was choking at night.

My septoplasty saved me and I no longer use Afrin. My sense of smell returned after a year post surgery.

Few weeks ago I had a cold and a stuffy nose and tried Afrin which was wonderful but stopped it after 3 days. That stuff is evil!

Today, I only use NeilMed Sinus Rinse morning and night and love it. It's the most effective way to clean your nasal passages and when sick it drains the passages of all the gunk. Cannot recommend the sinus rinse enough!

semerda··on Update on Omicron
Replication-incompetent adenoviral vectors? Lex Fridman had a virologist on his podcast talking about the mutations done to the adenovirus to make it safe for the delivery of the s-protein (used in viral vector J&J + AstraZ vax). Maybe I misunderstood that?
semerda··on Security Threat Model Review of the Apple Child Safety Features [pdf]
“Human review and reporting” - fact checkers?

Or are we to assume that their AI is 100% effective.

This will not end well..

semerda··on Show HN: OCR Invoices and Receipts in Seconds Using Go SDK
You can Test Drive It here https://www.veryfi.com/data-intelligence/ (halfway down the page) without signup or a 14 day free trial here https://hub.veryfi.com/api/hn/ (just email req to get going)

Let me know what you think.

PS. I'm one of the founders.

semerda··on Show HN: OCR Invoices and Receipts in Seconds Using Go SDK
This API extracts around 50+ fields in standardized JSON format inc 16 column table types (line-items) in seconds: https://www.veryfi.com/data-intelligence/

Alternative solutions are things like Mechanical turk at 1c per field or other solutions which vary in accuracy and typically use human in the loop and can range up to $1 per invoice.

In the end, it all depends on your application. If you need 1 or 2 fields then you can get away with other solutions. If you are building a competitive secure product and will use this wealth of data for business intelligence (cpg retail, bill pay, hotel folio) then 16c for a starter plan without a contract is a great price.

There's a free 14 day trial here https://hub.veryfi.com/api/hn/ and just requires your email to experience the product. Nothing to loose.

semerda··on Show HN: How does the French health pass work?
Gattaca. I’m curious tho where does it stop. For example, US stopped TB vax long time ago while half of EU continues. Those born in EU bear the scars on their arms from the vax. Sure TB isn’t as prevalent in the US as it used to be but there’s nothing stopping it from coming on a plane.

Bacterial infections of the lungs are very hard to fight esp with the increase of antibiotic resistance. A single cough from a TB infected individual used to be a death sentence to the receiver (prior to antibiotics).

So where does all this start and end. If we are serious about health while traveling then let’s go all in across the germ spectrum and see what happens ;-)

I’d love to see planes reporting on cabin air quality as well. I’m sure I’m not the only one who gets sick (pre Covid) when traveling long haul.

semerda··on Justice Department Sues to Block Visa's Proposed Acquisition of Plaid
Where they aren’t using APIs and instead the scrapers, does that mean they have your banking login credentials? Be curious to hear how they get around MFA.
semerda··on Bill introduced to promote prescribed fire intends to reduce fire risk
I’m sick and tired of this ego protection through projection. These attitudes go nowhere. The CA fires are “wildfires” right? They start in those beautiful golden Californian grassy hills. Imagine if the state leadership took care of that land they own through back-burning to avoid forest destruction. What can the state control today; better land management. Let’s start there and see how far it gets us. Global warming isn’t an overnight fix but land management might.
semerda··on Ontario doctors sign letter to Premier advising against sweeping lockdowns
So first you denounce my statement then you agree with it (around vaccines)?

I’m comparing RNA based viruses not diseases. If the keyword “flu” offends you because you think I’m comparing it to the flu then replace it with any RNA based virus and it’s mutation rate. You’ll realize fast that the thing called cure is only 100% effective when the mutation rates are close to 0.

semerda··on Ontario doctors sign letter to Premier advising against sweeping lockdowns
I have been following this mess. I’m an Aussie in CA.

Even when a vaccine is available it’s not going to be 100% effective. Contrast it to another RNA based virus (but faster mutating) like influenza. The annual shot effectiveness fluctuates based on what is the dominant strain socially circulating.

Therefore, the science Dan is subscribed to means Vic will be locked down indefinitely. Sure ppl love the lockdowns but the reality will hit hard when they realize there is no such thing as “pause” in the economy. It’s a hard stop followed by CPR.

What ever happened to real science; you know, the one where we learn and adapt as new information is made available. I’m pretty sure we now know a lot more about this virus, demographics most at risk, it’s disease management etc...

As Frank Herbert says; Fear is the mind killer.

semerda··on Does storing bread in the fridge make it last longer? (2019)
This article bugged me. It spoke about the fridge as a preservation tool but failed to point to the freezer. The very important part of a fridge! We all know that the freezer plays a big role in preserving all our produce. I cut and freeze all the bread I buy and bake and when I defrost it, it’s top notch!
semerda··on American Academy of Sleep Medicine calls for elimination of daylight saving time
Daylight saving is not observed in few Australian states like Queensland, the Northern Territory, Western Australia, Christmas Island or the Cocos (Keeling) Islands. They seem to be doing well.
