I am making available some Windows network tools that I have developed for my own use. Purely amateur use of these programs is free of
charge, but use of these programs for any commercial or for-profit purposes requires
registration. If you like these programs, and wish to say "Thank you", or if
you want technical support, you can register my Network Tools,
or by sending me an Amazon Gift Certificate here: Hot Download Macos Catalina 10157 Dmg _top_Your ISP offers you 30MB of disk space, but doesn't tell you how much space is used! This tool enables you to get a usage piechart from your FTP service, showing which directories are taking the most space, and to drill down into those directories to see which are the largest files. Simply double-click on a pie segment to drill down! FTPpie is recommended by Blueyonder (UK broadband ISP, now Virgin Media), and works on Linux under WINE. V1.4.0 approximate folder space occupied as well, trap potential error with UNIX servers, don't require separate run-time library Simply enter your user details and click on the Open site button:
and you will see the program working to retrieve your Web space usage details. Please note that the site name and directory details will be different for your ISP. Once the program has finished, a pie-chart like the one below will be displayed, and you can double-click on a directory to drill down and see its contents. This makes it very easy to clear out the maximum space with the minimum effort!
Blueyonder Users UpdateFor the recently released PWP2 service you will specify your address differently. Your old FTP upload address was: www.<aliasname>.pwp.blueyonder.co.uk, but instead you should now use: ftp.pwp.blueyonder.co.uk and enter your <aliasname> and <password> in the site details dialog. Hot Download Macos Catalina 10157 Dmg _top_This program allows you to compare your PC clock with a number of external sources. You may have an Internet or GPS time service, but is your PC accurately synchronised to those sources, and how do they compare with one another? For the most accurate synchronisation, your PC needs an NTP client, which will connect to an NTP service on the Internet. Perhaps your ISP already provides such a service?
Version history:
If you find the NTP Monitor useful, you can "thanks" by registering my Network Tools Suite here. Registration is mandatory for commercial use. Screen-shot from an earlier version:
The clocks have four hands displaying the offset:
Version 5 of the NTP monitor adds the ability to see trends over several hours by plotting a graph of the offsets against time. These offset can either be relative to the local PC clock, or compared to a more accurate reference source. The program allows you to filter the display in two ways, to improve the visibility of trend information:
Hot Download Macos Catalina 10157 Dmg _top_During the tests on a Windows version of the NMEA/PPS ref-clock drivers, the need arose for a simple program to plot the performance. As a result, development of the NTP Plotter program was started to produce graphs of offset, frequency error, and jitter like those below, from the loopstats files which ntpd can produce. The offset plot includes an hourly RMS estimate of variation of offset about the mean offset level. The jitter graph includes an extra averaged value, presented on a more detailed scale, so that even small changes can be observed, such as the change from user-mode to kernel-mode time-stamping. The program will accept command-line parameters as either a directory containing loopstats/peerstats files, a single file, multiple files, or a Zip archive with peer/loopstats files, and you can drag-and-drop the same three sources onto the program from Windows Explorer.
Hot Download Macos Catalina 10157 Dmg _top_Small program to check whether your NTP is detecting a leap-second flag, and if so, from where. My thanks to Dave Hart for suggesting the commands required to extract the leap-second data. The program needs write-access to the directory where it is copied, to write a temporary file, so for Windows-7 I suggest installing in a fresh directory such as C:\Tools\NTP\ Note: please ensure that the ntpq.exe program is available from the path where the program is run, as the program relies on executing the ntpq command and interpreting its output.
For those of you running FreeBSD or Linux, or if you prefer a program with the source you can inspect, here's a version very kindly provided by Terje Mathisen from Norway.

It seems that nodes with antennas away from the street were slightly less affected (no, I couldn't see any unusual vehicles). I wrote a DOS script to check both my Raspberry Pi flock, and some named Windows and Linux nodes. The idea was to detect those node claiming PPS sync and list them with the output from the appropriate line from an ntpq -pn. There is a common subroutine, called with two different sets of node names, one for the Raspberry Pi cards (RasPi1..RasPi14) and again for named nodes (in the set nodes= command). The set node=%node:~-8% command ensures that the displayed node name is padded to make it a constanst width, so that the NTPQ columns line up as expected.

It is widely remembered for two things: being the first macOS to drop 32-bit app support entirely and being the final bridge before the radical transition to macOS Big Sur and Apple Silicon. 1. Key Improvements in 10.15.7 The 10.15.7 update was primarily focused on stability and bug fixes that plagued earlier iterations of Catalina. Its primary fixes included: Connectivity : Resolved critical issues where Macs failed to automatically connect to Wi-Fi. iCloud Sync : Fixed bugs that prevented files from syncing properly through iCloud Drive. : Addressed a specific flickering line issue on 2020 27-inch iMacs equipped with Radeon Pro 5700 XT graphics cards. 2. How to Secure the DMG File hot download macos catalina 10157 dmg Official Apple support for Catalina ended in November 2022, but the software remains available for users maintaining older hardware. The macOS Catalina 10.15.7 release (build 19H2) was primarily a maintenance and security update designed to resolve critical bugs and vulnerabilities before the transition to macOS Big Sur. Key Fixes & Enhancements The 10.15.7 update specifically addressed three major performance issues: Wi-Fi Connectivity: Resolved a recurring bug where Macs would fail to automatically connect to known Wi-Fi networks. iCloud Drive Syncing: Fixed an issue that prevented files from syncing properly through iCloud Drive. The Legacy of macOS Catalina 10 Graphics Reliability: Addressed a specific graphical glitch affecting the iMac (Retina 5K, 27-inch, 2020) equipped with the Radeon Pro 5700 XT. Security Features While 10.15.7 initially focused on stability, it was followed by several critical security updates, including Security Update 2022-005 and a specialized 2026-001 Update: macOS Catalina Manuals and Downloads - Apple Support I can’t help with or promote sharing pirated software or direct links to macOS installer DMGs.

Please note: If you are using Windows for NTP with a PPS signal, the DCD line must flash briefly on, not be mostly on flashing briefly off as inverting the PPS signal is not supported by the Windows NTP port.
