Re: BleachBit 5.1.0 Beta adds cookie manager and expert mode guardrails

Yes, Linux computers do not slow down because of a bloated registry, but BleachBit doesn't claim to make computers faster.

Which kind of harm exactly? if there is a bug or usability issue, report it, so it can be fixed.

Maybe try running a preview to see what benefit you might get.

The map shows the trail from Austin Bluffs to Academy, but now the Cottonwood Trail reaches from Powers to the Pikes Peak Greenway Trail (by I-25) as a wide, paved trailed.

Re: More Evidence the FBI Fixated on Trump, Fixed for Clinton

Hi Nate,

The article states, "In this case the technical expert who worked for Bleach Bit and wiped Clinton’s server."

Actually the "technical expert" refers to Paul C. who worked for Platte River Networks. Also, there is no space in BleachBit. Source: I am the author.

Hi Mohd, Would you please give one example of an important file that BleachBit deletes as administrator that a user would likely regret deleting? Perhaps there is an opportunity to alter the list of files deleted, provide a warning, or better label the options.

P.S., I think you wrote this article, so thank you :)

In the screenshot the red permission denied errors look like the user needs to run as administrator for some options (like system logs, localizations, APT)

If you can reproduce any issues (you mentioned Chromium and KDE) in the latest BleachBit version (currently 1.6 stable or 1.7 alpha), please report them as bug tickets here http://bleachbit.sourceforg...

Re: How the new GMail image proxy works and what does this mean for you

I just tested this using my own system (basic Apache setup), and Google is caching the images. When I close and reopen the browser, Google doesn't request again. When I switch browsers from Firefox to MSIE, there is no second HTTP request.

Re: Forecasting: principles and practice

andrewziem — Fri, 01 Nov 2013 17:02:36 -0000

An organization has detailed information on its many individual customers and wants to forecast total customer attrition for months t+1, 2, and 3 with confidence intervals. Is this an extreme case of the hierarchical forecast in chapter 9.4? Do you have any recommended reading or advice on how to produce a forecast like this? I am thinking of looking at using GBM (Generalized Boosted Regression Models) with a survival response to estimate the hazard rates, and then aggregating up to the month.

Does the schedule imply the lectures are only live and not available as recordings? In other words, if I am not available Monday at 22UTC, I cannot participate?

Re: Don’t look at Average Time to Conversion

andrewziem — Fri, 12 Oct 2012 13:56:39 -0000

Using the method in the first part of the article, you would have a similar problem looking at the retention of customers, and your solution is like survival analysis (also called time to event analysis): cases are usually measured in days relative to a common event where 100% of the group is in one state (not converted) and eventually some, but often not all, members of the group change to a second state (converted). Survival analysis "whether and when" the cases (customers) change state (convert), or you can simplify it to just "whether" by looking at fixed periods such as 30 days or 90 days (as you suggested).

Re: Preface

Thank you. That makes sense. So if the trend were already flat and the slope were negative, the trend is decreasing.

Re: Preface

andrewziem — Thu, 31 May 2012 22:04:04 -0000

I am reading chapters 7 and 8 and am not clear on the distinction between trend, level, and slope. I don't see a glossary, and the site search is not helpful because it isn't in order. It may be nice to have these explained in one place with examples.

I admit I went quickly through the formulas, and now looking at figure 7.4 it's confusing to see a flat and negative slopes for sheep in Asia.

Re: My new forecasting textbook

Thank you! I am learning statistics and hope to dig into forecasting and time series to apply at the non-profit where I work.

Thanks, your code saved me some effort integrating Drupal with GAE by XML RPC.

Thanks, I didn't know about pychecker or pyflakes, and the static analysis actually found a real bug. :) By the way, all three checkers can be installed easily on Fedora via YUM from the standard repo's.

Re: BleachBit velocizza e ripulisce PC… e Firefox ;)

taralluccio: If you file a feature request for a Liferea cleaner (preferably in English) at https://bugs.launchpad.net/..., I will try to add it soon. (Soon BleachBit will make it easy to vacuum any SQLite database, but currently BleachBit version 0.5.4 only vacuums Firefox.)

Santiago: 39GB is the most I've seen!

Pollycoke: Thanks for the review! :)
