Nikon Explains How It Makes Lenses Smaller While Somehow Making Them Better

Lens design is a complex, delicate balance of competing ideals.

If you want to see how dysfunctional Congress is, just read any MSM news site right now.

Nutshell: The Senate passed a bill to pay the TSA workers after a marathon session, sending the bill to the House. But of course, House hardline MAGA reps are killing the bill, and are poised to bail today for a two-week PAID vacation.

Meanwhile, most large U.S. airports are still experiencing 4-6 hour lines to get thru security.

With midterms approaching, this is not a good look for House GOP.

With AI pushing data centres to their limits, the industry is shifting towards optical interconnects, which use light instead of electrical signals to enable high-speed, low-loss data transmission over longer distances.

Active in this space, KYOCERA recently introduced a new optoelectronic module supporting the PCIe 6.0 standard. Is this an important step forward in addressing performance and energy constraints?

Scientists involving the Max Planck Institute for the Science of Light are investigating changes in field oscillations that occur when light interacts with indium tin oxide (ITO) nanocrystals. This enables a better understanding of the time dependence of the characteristic interaction between light and the nanocrystals.

Do I know anyone here with experience in #Laser #Ablation? I have a VERY strupid question to ask 🙂

👁️ 🧠 This visual trick demonstrates how our #eyes and #brains prioritize contrast over accuracy.

When you watch the dot move across different backgrounds, your light-sensing cone cells become temporarily fatigued, creating an "afterimage" that makes the dot look like a #color that isn't actually there.

GSM and 5G data

We often take for granted the access we have to data & VOIP networks, esp. when we have 'unlimited access'

Unlimited data access is a farce

  • My ISP still delivers ancient xDSL connections maxed a 10MBit/s (1MBit = 1024kBit!)
  • The connection is capped at speed meaning 30days per bandwidth pool
  • * 10MBit/s = 36000Mbit/hr
  • * 36000Mbit/hr = 36864000 MBit/day (x24)
  • * 36864000MBit/day = 1105920000 MBit/month (x 30 days)
  • * 1105920000MBit /1024 = 1080000 MByte/month
  • * 1080000MByte /1024 = 1054.6875 GByte/month
  • * 1054.6875 /1024 = 1.02996826172 TByte theoretical bandwidth.

You get only 1.0299 TByte/month at max!

Subtract from that number 10% for protocol overhead ping delays retries and what not.

  • * 1.0299 TByte - 0.10299TByte = 0.9269TByte
  • * 0.9269 TByte = 949.1456 GByte max in practice

The practical cap is at 949.15GB per month

Similar calculations can be made for unlimited post paid POTS phone connections

  • The cap is at time. No one talks 24hrs and can pay the phone bill, so the cap is also economical
  • No unlimited services exist. All are capped by time*
  • Subscriptions can be a way out to good deals
  • One of my GSM providers gives 100 minute prepaid subsciptions for 6 months a year and two years
  • The difference is startling in comparision with the regular price
  • 100min = 4.5 USD per month subscribed prepaid 6 months
  • 100min = 25 USD month prepaid!

Don't take your connections for granted.

  • Many people (me included) drop permanent services due to economical & technical reasons
  • * I dropped my xDSL connection because I need fibre connections to work. My ISP has the fibre optic cables & FAT terminals (fibre acces terminals) in the first part of the street.
  • * * My ISP even made the power company change the poles in the whole street
  • * * The EBS changed the poles in 40% of the project time, a record for them.
  • * * My ISP betrayed us by still giving us FTTC instead of FTTH as promised in the whole street.
  • * * My ISP has massive corruption problems, since they abused the grand for FTTH to give us obsolete FTTC equipment with xDSL
  • * * Only areas without POTS cables got FTTH first, the rest was shoved on obsolete ancient FTTC equipment you cant buy new anymore globally
  • * * The ISP makes double money since they cant charge more for FTTC minimal, but have to give 50MBit/s minimal because there are no lower caps allowed in the contract grand
  • * * The FTTH connection als0 gets your POTS phone connected to it
  • * * when a pole is ripped off due to a car hitting it, you are SOL without a seperate GSM / smart phone, because your POTS phone is now on a SPF (single point of failure).
    • * On xDSL the lines are buried so POTS lines are safer
    • I also dropped the xDSL service because the ammount of data I can download is pitiful on xDSL
    • I can use the cash literally for food since they charge a massive USD 20/month for the ancient connection
