If you’re having trouble downloading

Safari can handle most types of files found on the web, but you may occasionally have trouble downloading or opening a file. Here are some possible reasons.

Downloading is incomplete

You can’t open a file while it is being downloaded. Wait until downloading is finished, and then try again to open the file.

Sometimes a file isn’t completely downloaded because there was a problem or the file was damaged. Try downloading it again.

Choose Window > Downloads to view the list of downloaded files. If downloading is paused, click the Resume button. The Resume button is orange with a curved arrow.

You can’t find the file

If the file has been downloaded but you can’t find it, choose Window > Downloads to view the downloads list. To locate the file, click the magnifying glass next to its name.

Note: If you moved the file or changed the download location after downloading a file, Safari won’t be able to find or open the file from the Downloads window.

The file’s application can’t open the file

If you can’t open the file, you may not have an application that can open it. Check the site where you downloaded the file for more information.

If you can’t open the file with the application that created it, the file may have been corrupted during the download. Delete it and try downloading it again.

SharePoint 2013 People Picker error: “Sorry, we’re having trouble reaching the server.”

I have had a strange error today in my dev lab environment. First I recognized that I could not select users from the People Picker:

Sorry, we’re having trouble reaching the server.

Second I realized that I was not able to use any function that belongs to WCF web services such as the SharePoint REST API, e.g. at http(s)://<server9gt;/_api/web.

Using Fiddler I found this behavior:

HTTP 404 NOT FOUND on /_vti_bin/client.svc/ProcessQuery

Same for /_vti_bin/client.svc/web which is the same as /_api/web.

Search the web I found some hints regarding this error in SharePoint. But nothing worked.

Than I created a own web service “service1.svc” with a simple method in it and placed it in folder <SP-Hive9gt;\isapi where the virtual folder “_vti_bin” is located on the file system.

Result: I could not call my own web service too. Same result: NOT FOUND.

Than I search the web for “WCF 404” and found some hints to “HTTP Activation” feature of Windows Server OS. Of course this was activated for .NET 3.5 and .NET 4.5.

So I deactivated the “HTTP Activation” feature of .NET 3.5 and .NET 4.5 and re-enabled one by one (1st .NET 3.5, 2nd .NET 4.5 ) them after deactivation.

After that I did a IISRESET. – Than everything works again as expected.

8 Reasons You’re Having Trouble Concentrating

Why Your Thoughts Wander, and What You Can Do About It

When people lose focus, they tend to blame themselves. You may decide you’re not trying hard enough, or you’re not thinking the right way, but these aren’t accurate assessments. When it comes to concentration, a lot has to do with your physical health, immediate surroundings, and natural mental tendencies.

In order to improve your concentration, you need to create conditions that make it easier to focus. Once you understand what commonly interferes with attention, you can shake up your routine and shift your perspective to restore your focus.

It’s no surprise fatigue can sap concentration. Since the mind and body are connected, depleting the body’s energy will surely encourage fuzzy thinking and problems with focus. Indeed, studies show that sleep loss impairs a variety of brain functions, from attention span to memory.

But did you know staying up just one hour longer than usual can affect your focus the next day? Not only is fatigue one of the strongest concentration-killers, it also adds up more quickly than you might imagine. Every person has slightly different sleep needs, but if you’re getting less than seven hours a night, consider making some adjustments to allow for a bit more shut-eye.

9 Sneaky Reasons You’re Having Trouble Losing Weight

Re having trouble

It’s a tale as old as carbs: you really, really, really want to drop pounds—but you really, really, really haven’t. Picture this. You’ve been to 20394802384 ClassPass classes. (Pilates? Check. Indoor cycling? Check. Yoga? Check.) And it’s been months (or, what seems like months) since you’ve eaten a piece of cake or a slice of pizza. (Alcohol? What’s that?) But the number on the scale? It doesn’t seem to care about your weight-loss efforts, because it’s been the same for weeks and weeks.

Cue: Confusion. Frustration. Next, you curse the ice-cream gods and wonder, “Does it burn calories when my head ‘spins’?” (No, actually. Stress can produce “cortisol,” a hormone that can cause weight gain—not weight loss.)

So, what’s to blame? What are you doing? Or, actually, what aren’t you doing? There are a number of “sneaky” reasons that your weight-loss efforts aren’t rewarded. Here, Dr. Westin Childs —a doctor who focuses on weight loss as well as weight loss–related issues—discusses the “sneakiest” reasons you might be struggling:

Our bodies (and our metabolisms) “calibrate” and “recalibrate” based on the amount of calories we consume—which means that calorie-restrictive diets aren’t effective. Dr. Childs explains: “Calorie-restricted diets have been shown to lower your metabolic rate and promote weight gain in the long term. This has been shown extensively in studies. Instead of focusing on calories, focus on the quality and content of your food along with adding in the other tips above.”

Our bodies need protein to function but, remember, protein is a “chore” to digest—and it can “overstimulate” the production of insulin and/or leptin. Dr. Child explains: “Consuming a diet that’s high in protein may over stimulate both insulin and leptin levels and can make weight loss difficult for patients. Protein is healthy in normal amounts to maintain muscle mass, but beyond these levels, protein may stimulate mTOR and make these conditions worse.”

You Might Have a Hormone Imbalance

There are clues when it comes to hormone issues (e.g., acne, hirsutism) that can cause problems when it comes to weight and weight gain/loss. Concerned? See the doc. Dr. Child explains: “Low testosterone can be a problem in both men and females. Testosterone helps build lean muscle mass and high levels of insulin lower your testosterone levels. This decreased muscle mass results in a lower metabolism as you burn less energy at rest (which means difficulty with weight loss).”

The incorrect amount of insulin can cause hyperglycemia (when there’s too much insulin) or hypoglycemia (when there’s too little insulin). These are both problems associated with diabetes and insulin issues. Dr. Child explains: “Insulin resistance can be to blame. Insulin promotes weight gain in fat tissues in the body and currently as much as 50 percent of the population has some form of insulin resistance. Unless you lower your insulin levels, you will not be able to burn fat—even if you run on a treadmill for hours per day.”

There are studies that demonstrate that diet is as important (if not more important) as exercise when it comes to weight loss—which means you can’t “out exercise” a bad diet. Dr. Child explains: “No matter how much you exercise, it will not account for changing your diet or eating healthy. Your diet influences your weight by influencing your hormones and exercising can only alter these hormones to a lesser degree. If you are interested in weight loss, you must also be eating healthy.”

The first and foremost “ingredient” when it comes to health? Sleep! Dr. Child explains: “A decrease in sleep has been shown to increase glucose levels and cortisol levels. Increased glucose leads to increased insulin resistance.”

Stress can cause increases in cortisol, which can cause increases in weight. Dr. Child explains: “Stress causes the release of your stress hormone cortisol which promotes weight gain. In order to lose weight, you must manage your cortisol levels and that means managing your stress.”

Our metabolisms are controlled by our thyroids (a gland in the neck)—so, problems with our thyroid mean problems with our metabolism. Dr. Childs explains: “One of the most overlooked reasons patients can’t lose weight is an undiagnosed thyroid problem. The thyroid helps to control your basal metabolic rate for your entire body. One of the causes of a sluggish thyroid is weight gain and a history of excessive dieting. This is how many patients who are overweight tend to make it more difficult for themselves by trying the latest diet fads. Each time they lose weight and then gain it back over a short period of time they are slightly damaging their thyroid.”

Remember to exercise. Second, remember to exercise with efficiency. Dr Childs explains: “Lack of exercise can obviously promote weight gain, but also make sure that you are doing the right type of exercise. High intensity interval training (or, HIIT) is more effective at dropping insulin levels than other exercises and can help burn fat better than aerobic exercise on a treadmill.”
