Today's edition of quick hits:
* Quite a day on Wall Street: "The New York Stock Exchange resumed floor trading Wednesday afternoon after an apparent technical issue halted trading in all symbols for nearly four hours."
* Quite a day in airports: "A computer system glitch left thousands of United Airlines passengers across the globe grounded Wednesday, causing a ripple effect of heavy delays throughout major airports."
* Eurozone: "Greece, running out of money and under a tight deadline from European leaders, requested a three-year loan on Wednesday from the eurozone's bailout fund as the country and its creditors began what could be a last effort to avert a historic rupture."
* China's crash: "So how screwed is China? And how screwed are we? According to Patrick Chovanec, a longtime China watcher who is currently chief strategist at Silvercrest Asset Management, the news for China is grim -- at least for a while. But the news for America is, well, pretty cheery. China's problems are part of a rebalancing that's long overdue -- and could well redound to America's benefit."
* Shake-up in Baltimore: "Mayor Stephanie Rawlings-Blake said Wednesday that she has replaced Police Commissioner Anthony W. Batts, citing 'utmost urgency' to stop a recent surge in violence."
* Iran: "As international talks with Iran over its nuclear program enter the eleventh -- and twelfth and thirteenth -- hour, the Obama administration is refusing to heed calls to leave the negotiating table."
* Good idea: "The U.S. Department of Housing and Urban Development on Wednesday unveiled a rule designed to bolster requirements that communities receiving federal dollars seek to break down historical patterns of segregation.... Under the new rule HUD will provide communities with data that must be used to analyze historical patterns of segregation."
* Another good idea: "Solar power is easy to dismiss as a thing for rich white people, a status marker for the Burning Man set. But the White House attacked that stereotype on Tuesday, launching a $520 million initiative to bring the power of the sun to the multihued universe of rental properties, housing projects, and other "low income" communities."
* A worthwhile endeavor for a better, future Congress to consider: "Sen. Tammy Baldwin (D-Wis.) and Rep. Bobby Scott (D-Va.) will introduce legislation Wednesday to make community college free for low-income students, fulfilling a promise made by President Barack Obama in his State of the Union address this year."
* The leaks to the media aren't the real problem here: "Capitol Police have suspended a sergeant in the Capitol division, allegedly in retribution for a leak related to Roll Call's May 1 report of three incidents in which officers left loaded guns in problematic places, such as the bathroom."
* It's discouraging to see Republican support for the Confederate flag actually grow a little over the course of the last 20 years.
* A dangerous idea: "An iPhone case that looks like a handgun is drawing warnings that it could be too easily mistaken for a real weapon. That has been the message for weeks from some police departments in the United States, concerned that the case could add to the uncertainty of confrontations with suspects."
* Congratulations to Dave Weigel for his new gig at the Washington Post. The paper is lucky to get him back.
