OpenJDK proposal would streamline Java records creation

Info World - Thu, 02/29/2024 - 12:30

Java developers would gain an easier way to create records, and more streamlined code for declaring record classes, through derived record creation, a preview language feature being considered by the OpenJDK community.

Derived record creation would allow developers to create new records from existing records, specifying only the components that are different. Goals of the proposal include providing a concise means to create new record values from existing ones and streamlining the declaration of record classes by eliminating the need to provide explicit wither methods, which are the immutable analogue of setter methods.

Columbus man pleads guilty to attempted murder for Whitehall car shooting

News Channel 4 - Thu, 02/29/2024 - 11:30

COLUMBUS, Ohio (WCMH) -- A third Columbus man has been sentenced to prison for a "gang-related" car shooting in 2022 that spurred from a bar fight in Whitehall.

Breon Kelly, 21, entered a guilty plea on Tuesday for his role in the Jan. 23, 2022, incident and was been sentenced to 32 to 33 and a half years in prison, according to Franklin County Prosecuting Attorney Gary Tyack. Kelly marks the third and final person to plead guilty in the shooting after his co-defendants, Larry Latham III, 21, and Mark Smith Jr., 21, pleaded guilty in May and April of last year.

Tyack said the "gang-related shooting" began after a large fight at PKWY Lounge and Grill at 5200 Riding Club Lane, when the three defendants got into a car and chased another car with three people inside. Tyack said Smith and Kelly both fired shots at the other car while Latham drove.

Kelly used a Glock switch to convert his gun to an automatic weapon, and struck the car and two additional cars, including one with a 7-year-old inside. No one was injured in the shooting, Tyack said.

Kelly had chosen to take his case to trial, but pleaded guilty right before opening statements. Tyack said Kelly was immediately sentenced for two counts of attempted murder, one count of discharge over a prohibited premises and one count of having a weapon while under a disability.

Lathan pleaded guilty on May 2, 2023, and was sentenced to 11 to 13 and a half years in prison for two counts of attempted murder, one count of discharge over a prohibited premises and two counts of having a weapon while under a disability.

Smith pleaded guilty on April 27, 2023, and was sentenced to 17 to 20 years in prison for two counts of attempted murder, one count of discharge over a prohibited premises, two counts of having a weapon while under a disability.

Guy Fieri's inaugural Flavortown Festival in Columbus has been canceled

News Channel 4 - Thu, 02/29/2024 - 09:56

COLUMBUS, Ohio (WCMH) -- The inaugural Flavortown Festival, a weekend-long Columbus event spearheaded by celebrity chef Guy Fieri, has been canceled due to "unforeseen circumstances."

The event was scheduled for June 1 and 2 at The Lawn at CAS with rock band Greta Van Fleet and country star Kane Brown announced in January as the festival's headline performers. Tickets had already been available for purchase, with a two-day pass starting at $155.

"Due to unforeseen circumstances, Guy Fieri’s Flavortown Fest, initially planned for June 1-2 in Columbus, Oh, has been canceled," a spokesperson said in a statement to NBC4. "Thank you to all our Flavortown Fest fans for understanding and your support along this journey."

The spokesperson said organizers are issuing full refunds to everyone who purchased passes.

Daylight saving time: When will clocks spring forward in Ohio?

The festival promised a fusion of food and funk, embodying Fieri’s dynamic personality and charitable ethos. Along with the Mayor of Flavortown himself, the festival would have featured eats and experiences from some of Guy’s favorite Triple D restaurants from the Columbus area and around the country while offering the ultimate experience for foodies.

In addition to Greta and Brown, several other acts were scheduled to perform on the main stage, including the frontman of rock band Poison, Bret Michaels, country-music duo LOCASH and country artist Niko Moon.

"I was actually born in Columbus, Ohio, so one might say it's pretty much the birthplace of Flavortown," Fieri said when announcing the festival last November. "But in 2024, we're making it official with the launch of Flavortown Fest, two full days of awesome music, the best chefs, real deal food from around the nation and a whole lotta fun that you’re gonna have to see to believe."

The cancellation comes as Fieri is opening a new restaurant this spring in Columbus, a yet-to-be-named Italian concept inside Scioto Downs at 6000 South High Street. A Scioto Downs spokesperson said the restaurant will feature "an old-school Italian feel polished with textured glass screens, rustic wood finishes, an open pizza & pasta prep station and gallery walls."

The festival was also supposed to launch Flavortown Cares, an impact program to support the Columbus community which would have donated a portion of proceeds from every ticket sold to the National Veterans Memorial and Museum, Ronald McDonald House Charities of Ohio and the Mid-Ohio Food Collective.

Still, a $10,000 donation will be made to the three charity partners that would have benefitted from the festival.

Video: See 100-mph tornado as it nears Madison County homes

News Channel 4 - Thu, 02/29/2024 - 08:51

LONDON, Ohio (WCMH) – A security camera outside of a Madison County home captured one of the five confirmed tornadoes that touched down in the central Ohio area Wednesday morning.

According to Christopher Estep, of Lilly Chapel, in north Fairfield Township, a security camera from his home captured a tornado that passed over Wilson Road Southeast in Madison County. The video shows the confirmed EF-1 twister heading east From London towards West Jefferson.

Daylight saving time: When will clocks spring forward in Ohio?

The National Weather Service confirmed that at 5:14 a.m., the EF-1 twister touched down east of London and traveled around 8 miles, ending southwest of West Jefferson at 5:23 a.m. The tornado’s estimated maximum speed was 110 mph and it spanned approximately 250 yards in maximum path width.

Downtown Columbus hotel accused of violating ADA, not being wheelchair-accessible

News Channel 4 - Thu, 02/29/2024 - 08:30

COLUMBUS, Ohio (WCMH) – A Downtown hotel is being accused of violating the Americans with Disabilities Act by not being wheelchair-accessible. 

A man with physical disabilities is suing the Westin Great Southern Columbus for several architectural features he said render much of the building inaccessible to wheelchair users. In his federal complaint, filed Feb. 13, the man said he encountered several ADA violations while visiting the hotel in November, including in the front entrance, multiple restrooms and the accessible room he booked for his stay.

The man, Spencer Neal, is paralyzed and uses a wheelchair. He comes to Columbus frequently to visit friends and said in his complaint that he chose the Westin, located on the corner of South High and East Main streets, because of its proximity to friends’ residences and its price.

But Neal encountered several “architectural barriers” he claimed impeded his full access to places including the fitness area, bar and dining area, multiple restrooms and his accessible room. The complaint does not detail specific inaccessible features but asks for full discovery in the case.

“Mr. Neal suffered a loss of his civil rights and his rights as a person with physical disabilities to full and equal access to public facilities, and further suffered from physical personal injury, shame, humiliation, embarrassment, anger, chagrin, disappointment and worry,” his complaint reads.

The building the Westin occupies was originally named the Great Southern Hotel and Theatre and is listed in the U.S. National Register of Historic Places. Opened in 1896, the theatre – currently run by the Columbus Association for the Performing Arts – is the oldest operating theatre in Central Ohio and one of the oldest in the state.

Dispute puts Ohio Statehouse approval of $1.4 billion in projects in jeopardy

As a place of public accommodation, the hotel is subject to federal and state accessibility requirements, regardless of its age or historic character. Neal’s complaint contends that the hotel not only violates federal and state disability accommodations laws, but falsely advertises itself as accessible. Neal seeks damages for his November stay and court-ordered renovation of the hotel to fix inaccessible features.

The Westin Great Southern hotel is operated by Marriott International. Marriott International did not respond to a request for comment. The owner of the building, a corporation called MHF WC VI, has until March 8 to respond to the complaint.

Why passkeys will replace passwords

Info World - Thu, 02/29/2024 - 03:00

With the growth of sophisticated attacks against critical software and infrastructure systems, multi-factor authentication (MFA) has emerged as a critical layer of defense against unauthorized access. An increasing number of enterprise and developer-facing technology applications and platforms, from GitHub to Salesforce to Amazon Web Services, are making MFA mandatory for users.

That said, we are all used to passwords, and many people like the status quo. Not surprisingly, the introduction of MFA has added friction to the login process. This can negatively impact the user experience.

A newer technology that can provide even greater security benefits than MFA is now becoming more widely deployed. That technology is called passkeys. Based on widely accepted industry standards, passkeys offers the tantalizing promise of eliminating the need for passwords and the risks passwords create without adding user experience friction like MFA.

AO-92 Reenters Earth’s Atmosphere

After just over six years in orbit, Fox-1D, designated as AMSAT-OSCAR 92 (AO–92), likely re-entered the Earth’s atmosphere on February 3, 2024 (Space-Track had not issued the final decay message as of the time of this writing.)

AO-92 was a 1U CubeSat developed and built by AMSAT. It carried a single-channel transponder for mode U/v in FM and also had an L-band converter (the AMSAT L-band downshifter experiment), which allowed the FM transponder to be switched to an uplink in the 23 cm band.

In addition to the transponders, the satellite carried the following scientific and technical payloads:

  • High Energy Radiation CubeSat (HERCI) built by the University of Iowa
  • Camera Experiment built by Virginia Tech
  • MEMS GYRO Experiment built by Penn State-Erie

The satellite had a single whip antenna for the 70 cm and 23 cm bands (uplink), as well as an antenna for the 2m band (downlink).

AO-92 was launched on January 12, 2018 at 03:59 UTC on an Indian PSLV XL rocket, along with the main payloads Cartosat-2F, NovaSAR-S, and 31 other small satellites from the Satish Dhawan Space Center, India. At 05:17 UTC, the antennas were deployed over the North Pole and the satellite began to operate. At 05:28 UTC the first telemetry was received.

On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President – Engineering Jerry Buxton, N0JY, announced that AO–92 had been commissioned and formally turned the satellite over to AMSAT Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, then declared that AO–92 was open for amateur use.

Rick Behma, VE4AMU, working AO-92 in Mode L/v with a Kenwood TM-941 mobile transceiver and Comet CYA-1216E yagi crossed with 2 meter Arrow II elements.

In addition to a very popular U/v transponder, the satellite provided a couple of unique capabilities. First was the L-band downshifter experiment, which was generally activated for 24 hours each Sunday while the satellite was able to support it. Pre-launch estimates suggested that approximately 100 watts ERP would be required to access the satellite, but much lower power outputs proved to be usable. Many stations operated through the satellite with radios such as the Alinco DJ-G7T at 1 watt of output into handheld antennas of between between 10 and 16 elements. At least one station reported accessing the satellite with just a simple whip antenna on 23 cm.

The camera, developed by students at Virginia Tech, also proved to be popular and delivered many good pictures, with the last photos received on September 19, 2020. An archive of all of the photos captured by ground stations can be found at https://www.amsat.org/tlm/showImages.php?id=4.

The distance record on AO-92’s U/v mode was 5,011 km – a transatlantic QSO between F4DXV and VE1VOX that took place on August 10, 2020. The record via the L/v mode was 4,202 km between OA4/XQ3SA and XE1MEX on June 3, 2020.

By early 2021, the aging NiCd cells – having been purchased in the early 2010s along with the rest of the Fox-1 battery cells – had degraded to the point where the satellite was entering safe mode on every eclipse. It was rarely operational in recent months. The transponder was occasionally turned on, but usually defaulted into “Safe Mode” at the next eclipse. The last telemetry frame was received from the satellite on October 27, 2023 at 01:36 UTC.

By every measure, AO–92 was a tremendously successful amateur radio satellite, providing educational and research benefits to AMSAT’s university partners, as well as providing several years of reliable FM communication for amateurs. Its useful life far exceeded the average operational lifespan for commercial or educational CubeSats.

The First Amateur Radio Station on the Moon

A rendering of the Smart Lander for Investigating Moon (SLIM) on the lunar surface. [Japan Aerospace Exploration Agency, image]The Japan Aerospace Exploration Agency (JAXA) successfully landed their Smart Lander for Investigating Moon (SLIM) on January 19, 2024. Just before touchdown, SLIM released two small lunar surface probes, LEV-1 and LEV-2.

LEV-2 collects data while moving on the lunar surface, and LEV-1 receives the data.

The JAXA Ham Radio Club (JHRC), JQ1ZVI, secured amateur radio license JS1YMG for LEV-1, which has been transmitting Morse code on 437.41 MHz since January 19. The probe uses a 1 W UHF antenna with circular polarization and is transmitting “matters related to amateur business.”

Radio amateurs have been busy analyzing JS1YMG’s signal, with Daniel Estévez’s, EA4GPZ, blog introducing the method and extraction results for demodulating Morse code from the signal, as well as extracting the code string.

It’s unclear how long signals will be heard. JAXA has said that SLIM was not designed to survive a lunar night, which lasts about 14 days, and is due to return in a few days.

SLIM was launched on September 6, 2023, and landed on January 19, 2024, with the mission of analyzing the composition of rocks to aid research about the origin of the moon. SLIM’s landing made Japan the fifth country to achieve a soft touchdown on the moon. The landing was achieved with exceptional precision — within 180 feet of its targeted touchdown location.

Lunar Excursion Vehicle (LEV–1) Amateur Telemetry Received

The Japan Aerospace Exploration Agency (JAXA) confirmed on January 20, 2024, that the Lunar Excursion Vehicle (LEV–1), a small robot deployed from the Smart Lander for Investigating Moon (SLIM), successfully conducted activities on the lunar surface. The telemetry data were sent directly from the small robot.

According to telemetry data, after deployment from SLIM, LEV–1 executed planned leaping movements and direct communication with ground stations, including inter-robot test radio wave data transmission from the Transformable Lunar Robot (LEV-2, nicknamed “SORA-Q”). On the other hand, image acquisition on the lunar surface has not been confirmed as of now.

Currently, LEV–1 has completed its planned operational period on the lunar surface, depleted its designated power, and is in a standby state on the lunar surface. While the capability to resume activity exists contingent on solar power generation from changes in the direction of the sun, efforts will be maintained to continue receiving signals from LEV–1.

Both LEV–1 and LEV-2 have become Japan’s first lunar exploration robots. Additionally, the small LEV–1 with a mass of 2.1 kg (including a 90g communication device), achieved successful direct communication with Earth from the moon. This is considered as the world’s smallest and lightest case of direct data transmission from approximately 380,000 kilometers away.

Furthermore, the accomplishment of LEV–1‘s leaping movements on the lunar surface, inter-robot communication between LEV–1 and LEV-2, and fully autonomous operations represent groundbreaking achievement. It would be regarded as a valuable technology demonstration for future lunar explorations, and the acquired knowledge and experience will be applied in upcoming missions.

Moreover, the transmission of UHF band radio waves from LEV–1 as part of outreach efforts has encouraged participation from amateur radio operators globally, and we have been receiving reports of successful signal receptions. This initiative provided an opportunity for the public to be directly engaged in lunar exploration missions. We would like to extend our sincere gratitude to everyone involved in the LEV–1 mission.

Changes to AMSAT-NA TLE Distribution for February 2, 2024

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

This week there are no additions or deletions to the AMSAT TLE distribution.

Request to Reconsider Decommissioning of IO-117 Under Evaluation by Italian Space Agency

On Thursday, January 25, 2024 S5Lab posted on X that the GreenCube (IO-117) Digipeater would be permanently deactivated on February 5th.

Designed and developed by students of Sapienza University of Rome, IO-117 is the first satellite to carry an amateur radio payload into a Medium Earth Orbit (MEO) of approximately 6,000 km.

The message from S5Lab read:

Dear Friends,

After one year and a half of operations, it is time to conclude the GreenCube operations with the planned de-commissioning activities. After the conclusion of the nominal experiment and with the digipeater payload active for more than one year, we will perform the passivation operations for the satellite.

The planned passivation operations will be executed on Monday, 5 February 2024, at 00:00 UTC. From that day, GreenCube will be completely passivated and the digipeater will be switched off for good.

We want to thank everyone that endorsed, supported or participated in the mission and the radio amateur community that enthusiastically became a true part of our project. We hope that GreenCube will somehow be part of your memories of radio amateurs, space engineering enthusiasts, and we hope to involve you soon in many more adventures.

Thanks once again for the unbelievable memories shared together… See you soon!

The GreenCube Team at S5Lab

That afternoon, AMSAT sent a letter to S5Lab expressing the organization’s desire to leverage our decades of experience and work with S5Lab, AMSAT Italia, other AMSAT organizations, and the amateur satellite community at large to overcome any obstacles, regulatory or otherwise, to keeping IO-117 in service for as long as possible. AMSAT-DL, AMSAT-F, and other amateur satellite organizations also expressed similar sentiments. Peter Goodhall, 2M0SQL, began a petition on change.org that garnered over 1,500 signatures from amateur radio operators around the world in one week.

On the afternoon of Friday, February 2, 2024, AMSAT Italia made the following announcement:

AMSAT Italia would like to inform the amateur community that its request to the Italian Space Agency, the owner of the GREENCUBE satellite, to reconsider its decision of decommissioning the satellite is under evaluation.

Waiting for its decision, IO-117 is still operational.

The GreenCube satellite was born as a scientific experiment placed in MEO orbit which successfully concluded its mission.

IO-117 is the HAM Radio part of the satellite consisting of a digipeter which was promoted by AMSAT Italia and coordinated by IARU-R1.

At the moment AMSAT Italia is committed to promoting the continuation of the mission for the HAM Radio part of Greencube.

AMSAT Italia BoD

During its lifetime, IO-117 has proved to be a popular resource, allowing amateurs all over the world to obtain ARRL’s Worked All States (WAS) and DX Century Club (DXCC) awards via satellite and to boost their VHF/UHF Century Club (VUCC) grid totals. A strong presence by Japanese amateurs has allowed many to work all the Japanese prefectures. A few DXpeditions, such as TX5S to Clipperton Island, have also brought gear for IO-117 along and provided rare DX entities via satellite. Multiple future DXpeditions also plan IO-117 activities. AMSAT is hopeful that the satellite’s lifetime can be extended.
