Narrowing Down When Humans Began Hurling Spears

The history of ironworking in general is a total mess: Not only were the best techniques(at any given time and place) some combination of trade secrets and National Security Stuff, leading to dubious recordkeeping, iron and most iron alloys corrode enthusiastically, often leaving archeologists to stare at an intriguing-looking rust stain and puzzle from there.

Then(as in the case of Damascus steel, as you mention) the properties of iron(actually a pretty lousy material, pure) change quite dramatically with the addition of relatively small amounts of various alloying agents, frequently ones that weren't even identified as distinct substances(much less 'identified' as 'elements') until centuries later, in addition to being sensitive to heating/cooling parameters and any other treatments affecting crystal structure.

There were improvements over time, of course; but until fairly recently, with modern metallurgy and chemistry, even a good-faith effort by the original craftsman to share his technique would likely leave us with considerable puzzling left to do.

PFT: Arians impressed with Palmer's experience

John SchneiderAP

The Seahawks might lead the league in PED suspensions, but it?s apparently not for a lack of trying.

Seahawks General Manager John Schneider called Bruce Irvin?s suspension for violating the league?s policy on performance enhancing substances ?very disappointing,? and said the team has ?gone above and beyond what the league has done,? in terms of educating players.

Schneider?s remarks came on SiriusXM NFL Radio with Bruce Murray and Rich Gannon, and made it clear the team?s trying to curb a trend.

?This is something we take very seriously here,? Schenider said. ?The league has done a great job of educating guys and we?ve actually gone above and beyond what the league has done. We have a guy in place here that helps our player development people. You do what you can. It?s very disappointing.?Pete [Carroll] and I sat down with Bruce. Pete addressed it with the team.?Bruce addressed the team.

?And, you know, really good organizations are the organizations that can take body blows. We look at this as a learning opportunity and one that obviously needs to be addressed, but this is also an opportunity for others to step forward.?

The Seahawks prepared for the suspension by signing free agents Cliff Avril and Michael Bennett, but they?ll be required to change even more while they wait on Irvin to be reinstated and Chris Clemons to return from a knee injury.

?And we have to treat it really, quite honestly, like he sustained a high ankle sprain or something,? Schneider said. ?And you make those adjustments whether it be in the game or during the offseason.?

Schneider said after doing research on players in college, he?s not surprised at the numbers of suspensions.

But given the concentration in his own building, he should be treating it like a different kind of outbreak, rather than just a four-week injury which will inconvenience his coaches.

Inside Microsoft's ?Geek 2 Chic' Fashion Show, Where Tech Types Strike A Pose For Charity [TCTV]

Screen shot 2013-05-20 at 2.01.12 PMThe tech-dominated San Francisco Bay Area isn't exactly known as a hub for high fashion -- Facebook's new James Perse staff hoodies are about as fancy as things get around here -- and fashion shows aren't typically in our purview here at TechCrunch TV. So when we were invited to attend the Geek 2 Chic fashion show, an event hosted by Microsoft benefiting the Network for Teaching Entrepreneurship (NFTE, which is pronounced "nifty") which mentors at-risk youth and teaches them business basics and encourages technology careers, we had to check it out.

Who is building what in Sochi for 2014 Olympics

(AP) ? The cost of the 2014 Winter Games in the Russian city of Sochi now stands at $51 billion, making it the most expensive Olympics in history. More than half of the bill is being footed by Russian state-controlled companies and business tycoons. A look at what the major players are building in Sochi:

THE RUSSIAN GOVERNMENT

The government is building five of the six arenas in the coastal cluster, which will host indoor competitions such as ice skating, for about $10 billion. Deputy Prime Minister Dmitry Kozak, who is overseeing the Sochi preparations, said the government will spend a total of about $18 billion before the games begin in February 2014.

GAZPROM

The world's largest natural gas producer, a publicly traded company, has many Olympic projects in Sochi, including building a cross-country skiing and biathlon center, one of the three Olympic villages and an Alpine ski resort. Gazprom is also building a power station in a Sochi suburb for about $740 million and a pipeline to bring gas supplies to the Sochi area for about $1 billion. The total price tag for Gazprom stands at roughly $3 billion.

POTANIN

Metals tycoon Vladimir Potanin, whose fortune is estimated at $14.3 billion, started building the Roza Khutor ski resort before Sochi was picked to hold the 2014 Olympics. Infrastructure required by the International Olympic Committee cost $500 million, boosting his total bill in Sochi to $2.5 billion. In addition to the Alpine ski runs at Roza Khutor, Potanin's holding company, Interros, has built an Olympic village and a snowboarding and freestyle park.

DERIPASKA

Metals tycoon Oleg Deripaska, estimated to be worth $8.5 billion, is mainly involved in infrastructure development in Sochi. His holding company, Basic Element, is building an Olympic village, a sea port and has just finished revamping the Sochi airport. Basic Element expects to spend a total of $1.4 billion in Sochi.

SBERBANK

The state-controlled bank is set to spend at least $1.3 billion building a media center in Sochi, as well as a ski jump complex.

(AP) ? Syrian government forces pushed deeper into a strategic opposition-held town near the Lebanese border Monday, battling rebels in fierce street fighting, Syrian state-media said. An activist group said at least 23 elite fighters from Lebanon's Hezbollah militant group fighting alongside regime troops have been killed in the clashes.

The Britain-based Syrian Observatory for Human Rights, which tracks the country's civil war, said that in addition to the deaths more than 100 Hezbollah members have been wounded in the fighting around the town of Qusair. If confirmed, the casualties would be a significant blow to the Shiite group, which has come under harsh criticism at home in Lebanon for its involvement in Syria's civil war.

A staunch ally of Syrian President Bashar Assad, Hezbollah is heavily invested in the survival of the Damascus regime and is known to have sent fighters to aid government forces. The Lebanese group's growing role in the civil war next door also points to the deeply sectarian nature of the conflict in Syria, in which a rebellion driven by the country's Sunni majority seeks to overthrow a regime dominated by the president's Alawite sect, an offshoot of Shiite Islam.

The Observatory, which relies on a wide network of activists in the ground in Syria, cited "sources close to the militant group" for the death toll but declined to reveal their identity. It said at least 50 Syrian rebels were also killed in the battle for Qusair on Sunday, including two opposition commanders.

For weeks, fighting has raged around Qusair, a town in the central province of Homs that has been under rebel control since early last year.

The intensity of the fighting reflects the importance that both sides attach to the area. In the regime's calculations, Qusair lies along a strategic land corridor linking Damascus with the Mediterranean coast, the Alawite heartland. For the rebels, overwhelmingly Sunni Qusair has served as a conduit for shipments of weapons and supplies smuggled from Lebanon to opposition fighters inside Syria.

On Sunday, the regime launched an offensive to regain control of Qusair, with Hezbollah's elite fighters pushing into the town from the east and south, an opposition figure said.

He said Hezbollah troops took control of the main square and the municipal building in the center of the city in a few hours. By the end of the day Sunday, they pushed out rebel units, including the al-Qaida-affiliated Jabhat al-Nusra, from most of Qusair, he added Monday on condition of anonymity, for fear of retaliation by both sides.

He said fighting was focused in the northern part of the town on Monday.

The account matched that of Syria's state news media, which said President Bashar Assad's troops took control of most of Qusair on Monday. State-run TV said forces restored stability to the entire eastern front of the town, killing scores of terrorists there.

Residents on the Lebanese side of the border just across from Qusair reported seeing more than 30 plumes of smoke billowing from inside Syria and hearing the heavy thud of artillery and airstrikes late into the night Sunday and on Monday morning.

"Nobody could sleep last night from the sounds of battle," said Ali Jaafar, deputy mayor of the Lebanese border town of Hermel, adding that residents did not send children to school Monday for fear of fighting spilling over into Lebanon.

Before Sunday's offensive, Qusair had been ringed by regime troops and fighters from the Lebanese militia Hezbollah, an Assad ally, for several weeks.

Lebanese security officials confirmed at least four funerals were being held Monday morning for Hezbollah fighters or their supporters killed in Syria. They spoke on condition of anonymity in line with military regulations.

Army units "restored security and stability" to most of the city on Monday and killed "many terrorists," the majority of them foreign fighters who have been fighting alongside opposition forces, the state news agency said. The military also destroyed rebel hideouts and seized "large amounts of weapons and ammunition," it said, adding that government troops are fighting pockets of resistance in several districts of Qusair Monday.

The Syrian regime claims there is no civil war in the country but that the army is fighting foreign-backed terrorists trying to topple Assad's government.

More than 70,000 people have been killed in Syria since March 2011.

At least 1.5 million Syrian who fled civil war have sought shelter in neighboring countries such as Lebanon, Jordan and Turkey, while millions more have been displaced inside Syria and are in urgent need of basic aid, according to the United Nations.

An international aid organization, Oxfam, appealed for more funds to help Syrian refugees, saying warmer weather will increase health risks due to lack of shelter, water and basic sanitation in Lebanon and Jordan.

The Britain-based group said in a statement Monday that diarrhea and skin infections have already been noted among refugees in Jordan and Lebanon. The two countries host the bulk of 1.5 million Syrian refugees.

Oxfam said it needs $53 million dollars to improve access to water and proper sanitation for Syrian refugees. So far the aid group has received $10.6 million dollars.
