I have been using the PageSpeed score for several months to check against my website and it has been consistently around the 24 - 32 mark. In the last week or so I have had scores between 28 and 91, re-running it constantly gives different results. Has a new release or issue caused this problem? Is anybody else having the same issue?

I'm working on the HarvardX Data Science program. In the probability section, we are being asked to determine the probability of getting a score above 30. I have even plugged in the exact code that DataCamp reveals as the answer, but pnorm() still returns a value of 1 for any quantile I enter that's 27 or higher. I have attached my code for reference. Can someone point out what the issue is?
For reference see the image below:
R does automatic rounding for console output. visualizing. Various methods exist to print all significant digits. As we work in a 32 bit environment, we can print the first 15' digits using
sprintf("%.15f", pnorm(30,11,2.87))
#output
[1] "0.999999999982065"
Anything past the 15 digits is not trustworthy.
sorry if this is a newbie question but i have been having a very weird issue with my installation of kibana:
setting dateFormat:tz is set to UTC.
searches are working great and data is shown exactly as expected when the last minute in the graph is 3 hours before my local time (i'm at GMT+3 so it's accurate)
in time lion on the other hand I've been having an issue where i run a very basic time series like .es(*) and what i get is a graph where the last 3 hours is showing 0 entries. it seems that the timelion is not using the configured time zone for the graph limits but it is using the tz on the data.
any thoughts?
You need to set your data time field
.es(timefield=YOURFIELDNAME)
i have a problem in MS Project 2013:
i´d like to set up a work package that has a certain duration but in this duration there is no work like 8 hours x (duration in days) required but e.g. 5 days of work in a timeframe of 30 days.
this is annoying to set up but it works. now ms project does not draw the respective bar for 30 days of duration but only for 5 days (the work). at the end of the bar a little arrows goes on for another 25 days (resulting in 5+25=30days) and then turns down to the next work package. i´d rather like to see a bar for the full 30 days and then for the arrow to go down.
is there a way to do this?
it seems wrong that the bar depends on the work rather than the duration because it is not likely that the work gets done in the first 5 days and then you just wait for 25 days.
Create a new task and set the Duration to 30d and make sure the type is "Fixed Duration" and set the task's Work to 40h.
I'm facing difficulties to show the time time difference in hours where hours are greater than 24.
Right now I'm using the following in iReport
(new SimpleDateFormat("dd':'HH':'mm':'ss")).format(new Date($V{avgDuration}.longValue()*1000))
where $V{avgDuration} is a variable in jrxml file which is the average time difference between two dates in seconds. Here it shows the 1 day 1 hour but I want it to be 25 hour. What should I do?
I've solved the problem using PeriodFormatterBuilder. But for this, I need to use joda-time library.
In the expression editor of the text box in jrxml file, just wrote the following:
new org.joda.time.format.PeriodFormatterBuilder()
.printZeroAlways()
.minimumPrintedDigits(2)
.appendHours().appendSeparator(":")
.appendMinutes().appendSeparator(":")
.appendSeconds()
.toFormatter()
.print(new org.joda.time.Period(
$V{avgDuration}.longValue()*1000))
I tried to use Salesforce formula: Calculate business hours between two dates to count business hours between dates/times. However, for some records it returns negatives or 0 even though there is > 45 mins between the date/Times.
Any reason why this would be happening.
Thanks
Problem solved.
I ended up building a different method of calculation that works perfect.
The logic in the formula linked to above was slightly flawed.
