Input: Consider Input: The heir to Saudi Arabiaâs throne has accused  Iran  of âdirect military aggressionâ which could be an âact of war â after Saudi air defense forces intercepted a ballistic missile on Saturday fired toward the capital  Riyadh  from across the border in Yemen.
Yemen has been embroiled in a civil war since 2015 between a Saudi-led military coalition in support of the Yemeni government  and Houthi rebels believed to be funded by  Iran .
âThe involvement of  Iran  in supplying missiles to the Houthis is a direct military aggression by the Iranian regime â the Saudi news agency SPA reported  Crown Prince Mohammed Bin Salman  as saying on Monday  âand may be considered an act of war against the Kingdom.â The language closely matched a statement earlier given by the Saudi-led coalition.
 Iran  immediately denied  it  was behind the missile launch.
The head of the Saudi military coalition said that experts in military technology had examined other missiles and âconfirmed the role of  Iran âs regime in manufacturing these missiles and smuggling them to the Houthi militias in Yemen for the purpose of attacking the Kingdom  its people  and vital interests.â
 The crown princeâs  reported remarks mark a new height in tensions between  Iran  and Saudi Arabia  the regionâs rival powers. The civil war in Yemen is widely seen to be a proxy war between the two countries  and has resulted in the deaths of over 10 000 civilians and triggered a humanitarian disaster including a cholera outbreak which has infected nearly a million people.

Input: Consider Input: As Americans mourned the death of  the Rev. Billy Graham  on Wednesday  most remembered  him  as a pastor with the ability to lead thousands to Jesus  take presidents under his wing and console a nation after the Sept. 11 terrorist attacks.
But it was in the suburbs of Chicago where  he  learned how to amplify  his  voice as a preacher.
It didnât take long for  Graham  and the congregation of Western Springs Baptist Church   his  first pulpit after graduation from Wheaton College  to conclude  he  was better suited to preach in stadiums than sanctuaries.
âThis is where  he  got a taste of glory  a taste of fame and the gratification that comes from speaking to huge crowds â said Grant Wacker  author of âAmericaâs Pastor:  Billy Graham  and the Shaping of a Nation â a biography of the national icon. âAnd  he  got the response  he  was looking for.â
Indeed   Graham âs first revivals and rallies in downtown Chicagoâs Orchestra Hall and Soldier Field â forerunners to  his  later international crusades â launched the evangelist into the spotlight for decades to come and steered legions of people to church.  His  pioneering use of mass media including radio  television  magazines and motion pictures only broadened  his  reach.
 Graham  died Wednesday at 99 at  his  home in Montreat  N.C. Wheatonâs president  the Rev. Philip Ryken  said commemorating  Graham âs significant contributions to Christian ministry for the many generations born after  his  heyday would remain a long-term commitment of the flagship evangelical institution.
âI think  Billy Graham  will be regarded as one of the greatest Christian leaders of the 20th century â Ryken said  âand that legacy will last a very long time. â
Graham  a native of North Carolina   was already an ordained Southern Baptist pastor and graduate of Florida Bible Institute (now Trinity College of Florida) when  he  sought a liberal arts education and bachelorâs degree at west suburban Wheaton College in 1940.

After hearing the 21-year-old Graham preach in Florida  two members of the Wheaton College board  including the brother of its incoming president  hired  Graham  as their caddy on a golf course and offered to pay  his  first year of tuition if  he  attended the college.
 He  studied anthropology  which some say expanded  his  horizons beyond the biblical theology training  he  already had received.
âIt did make  him  aware in new ways of how societies work  how cultural values are shaped  things  he  could draw upon  especially as  he  traveled the world â said Edith Blumhofer  a professor of history at Wheaton College.
But even more important than the college curriculum were the people  he  met and walked alongside for decades to come  she said  including  his  future wife  Ruth Bell  a fellow student and daughter of Presbyterian missionaries.
It wasnât until 1941  that  Graham   then a 23-year-old college sophomore  took his place before a congregation. The Wheaton College president at the time  V. Raymond Edman  recommended that Graham replace him in the pulpit of Wheatonâs United Gospel Tabernacle.
âIt was where he acquired managerial skills for inspiring and leading organizations and expressing his ministry  not only by preaching but through other people â said  Robert Shuster  who oversees the Billy Graham Center Archives  housed at Wheaton.
âHe was not preaching what a pastor would normally preach to a church audience â said one of Grahamâs former classmates  the late Glyn Evans  in an interview with  Shuster  for the archive several years ago.

Input: Consider Input: GitLab  a startup with $25 million in funding  is having a "very bad day " as the company's interim vice president of marketing   Tim Anglade   put  it  to Business Insider on Wednesday after a series of human errors caused the service to go down overnight.
Making matters worse  the team couldn't just restore: "Out of 5 backup/replication techniques deployed none are working reliably or set up in the first place" the blog said. "We ended up restoring a 6 hours old backup." That means any data created in that six-hour window may be lost forever   Anglade  said.
While restoring that older version of the database  the site went down for at least six hours   Anglade  said. Intermittent failures sprung up for another several hours while the team got the service back online  with everything starting to get back to normal only on Wednesday morning.
The good news for users   Anglade  said  is that the database that was affected didn't actually contain anyone's code  just stuff like comments and bug reports.  Furthermore  Anglade  said the many customers who installed GitLab's software on their own servers weren't affected  since that doesn't connect to GitLab.com. And paying customers weren't affected at all   the company  said  minimizing the financial impact.
 Anglade  acknowledged the outage was bad  as is the looming possibility that some of that data may be gone  but nobody is going to have to start rewriting his or her software from scratch  and only about 1% of GitLab's users are expected to see any lasting effects from the incident.
As for the systems administrator who made the mistake   Anglade  is hesitant to place blame  saying  it  was the whole team's fault that none of  its  other backup systems were working. "It's fair to say it's more than one employee making a mistake " he said.
