I mainly work in python now so I'm not too familiar with the limitations of bash, but surely, for each url provider, you could instead make comparisons and generate an array of additions / removals and then make only the necessary changes? Say inserting a couple thousand urls instead of millions every time gravity is run? The time you'd lose in the extra checks would be gained back easily in DB updates?
However, note that there are no guarantees that everything works as expected. Although it should.
This also already features the idea of populating an alternative table called gravity_new and only swapping them in the end. I haven't had the time to check if this leaves all triggers and views intact, however, I hope so.
Appreciate the time you're putting in @DL6ER. Please don't take my comments negatively; I just think overall the update from v4 to v5 has been such an improvement that it would just be a shame if it were to stumble a little on gravity updates. It's only meant in a constructive manner.
I will install 2 new systems tomorrow, one with beta5 + database v10 and one with gravity_performance, using my adlist, regex and whitelist entries. This will take a while, I'll report back the processing times.
Testing with large blocking lists (of lower quality) will show if we can leave of the call to uniq (which consumes about 50% of the time in the gravity script! - about equally much as the entire database processing).
Yeah, that should have much the same affect as checking out that branch from a 5.0 system. If you want to be safe, go from 4.3.2 to 5.0, and then check out the gravity performance branch of core afterward. But it shouldn't make much difference!
In answer to that question: No, the "gravity" is always directional. You can play tricks by creating an object that's easily removed later (such as having an alpha of 1) which is against one of the canvas edges. When Gravity is applied, the original object will be moved to touch the newly-created object. (I fear this comment may not even make sense in English much less translated.)
You can easily add a PDF download link to Gravity Forms Confirmations and/or Notifications with the [gravitypdf] shortcode. Using the optional Entry Attribute you can include the shortcode on any WordPress page (good for Page Confirmations). If you only need the raw PDF URL, you can add the raw shortcode attribute or use the PDF Merge Tag instead.
Gravity Forms Notifications are automated emails sent after the form is submitted. If you would prefer not sending the PDF as an email attachment (usually for security reasons), you can use the [gravitypdf] shortcode to include a link to the PDF. Because of the default security protocols, this method is very effective when the recipient has a WordPress user account. If users aren't logged in when completing the form, or you want to email a link to the document to a third party, use the signed PDF URL feature.
While we provide a quick and easy way to get a particular PDF's [gravitypdf] shortcode, it's also useful to know what each attribute does, and how it affects the display of the PDF download link that gets generated.
If the [gravitypdf] shortcode doesn't display a link to the PDF, an error likely occurred. To verify this, enable Debug Mode in the Global PDF Settings and test again using an Administrator WordPress account. An error message will be displayed on the screen where the shortcode has been rendered and provide more information about why nothing was displayed.
Since you must constantly struggle against the force of gravity, your task is even more difficult. Inertia is simulated well in the game, and piloting the ship requires finely-honed reflexes. Each new level brings new obstacles and barriers, always in new formations; some even include physical puzzles that you must figure out how to get through -- particularly how to get to the freight. You must also watch the fuel level: accelerate too often, and you may run out of fuel.
This collection contains gravity gradient and gravity anomalies grids at ground level and at satellite height. In addition it contains the GOCE gravity field models (EGM_GOC_2, EGM_GCF_2) and their covariance matrices (EGM_GVC_2):
As output from the ESA-funded GOCE+ GeoExplore project, GOCE gravity gradients were combined with heterogeneous other satellite gravity information to derive a combined set of gravity gradients complementing (near)-surface data sets spanning all together scales from global down to 5 km. The data is useful for various geophysical applications and demonstrate their utility to complement additional data sources (e.g., magnetic, seismic) to enhance geophysical modelling and exploration.
Land and marine gravity surveys, grids, models, and geoids are listed below. Data parameters include latitude, longitude, observed gravity and elevation, Bouguer Gravity Anomaly (land), and Free-air Anomaly (ocean). Each dataset contains documentation, including source contributor.
Approximately 70 percent of the data are observed values--regional station data collections (separated primarily by contributors) and absolute gravity measurements. Grids and other derived summary data sets represent another 30 percent of the data.
A standard format description for the land gravity data preserves fields unique to a specific data collection. Marine gravity data are stored in the MGD77 format. Standard terminology, as well as minimum / maximum values and histogram distributions for each parameter are available. Point distribution plots are .PCX and .GIF images.
Orbit - Playing with Gravity is a puzzle game where you have to play with the forces of gravity to send planets into orbit around a black hole. Just tap the screen and drag your finger a bit to outline the orbit for your planets.
Calculate gravity and magnetic fields using standards such as 1984 World Geodetic System, 1996 Earth Geopotential Model (EGM96), the World Magnetic Model (WMM), International Geomagnetic Reference Field, and Spherical Harmony Gravity. Download ephemeris data for the Geoid Height block using the aeroDataPackage function.
Specific gravity testing is easy and efficient with the SBS-2003. Simply insert the nozzle into the battery and depress the finger pump, which draws a few drops of sulfuric acid (H2SO4) through the tube. Within three seconds the measured refractive index is converted into a temperature compensated specific gravity reading and the specific gravity, temperature and cell count are displayed. After testing is completed, you can transfer the data to your computer via Bluetooth and download results into an Excel report.
