2. David Virelles “Mbókò” (ECM) The brilliant young pianist David Virelles continues his interrogation of Afro-Cuban culture and ritual with methodical cool but also an openness of spirit. With Román Díaz thrumming a percussive heartbeat, this intoxicating suite resonates with implications both ancient and state-of-the-art.

Thor: Ragnarok was so much funnier than you could ever expect it to be, and it's all thanks to the genius of Jeff Goldbloom combined with the genius of Taika Waititi—the latter of whom both directed the movie AND played a extremely earnest dude made out of rocks.
Amid all of the current talk about whether government law enforcement agencies should be able to legally force Apple to unlock an iPhone to look for evidence, there is a machine available now at London's Fone Fun Shop that will find the four-digit passcode used to lock down an iPhone.

在出售给Facebook前,WhatsApp一直特别反对植入广告。该公司首席执行官让o库姆在自己桌上一直贴着联合创始人布莱恩o阿克顿留下的一张便条,随时提醒自己牢记公司的核心价值观:“不要广告!不要游戏!不要宣传噱头!”这样一来,短信应用只好想出别的创意。比如Tango就在用户的短信“收件箱”里插入广告。中国互联网巨头腾讯公司旗下的短信应用——微信,则通过游戏、贴纸(类似于表情符号)和移动购物等方式谋取赚钱之道。Kik则提供一种被一些人称为“聊天广告”的功能,用户通过它能和幽默网站Funny or Die及电影信息网站Moviefone这类品牌运营的聊天程序进行交谈。

Pregnancy symptoms during week 4

No symptoms?

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.

Tender, swollen breasts

Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.

Fatigue

For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.

Nausea or vomiting

Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Pregnancy checklist at 4 weeks pregnant

Take a pregnancy test

If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.

Make a prenatal appointment

If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.
