zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

4. Electric Heat Tracing
Before Installing Cable . . .
Read and carefully follow all installation procedures when
installing a Thermon electric heat tracing system1. Product
certifications and performance of heat tracing system is
dependant upon proper installation with certified Thermon
components.
1. Before removing the heating cable from the reel, an insulation resistance test should be conducted. The cable
should be tested with a test voltage of at least 500 Vdc.
However, for polymer insulated heating cables, 2500 Vdc
is recommended. The minimum acceptable level should
not be less than 20 megohms. All test results should be
documented.
The system must be installed in accordance with the
regulations EN IEC 60079-14 and IEC 62086-2 for hazardous
areas (where applicable). The system installation must also
comply with all local and national electrical codes.
Testing should occur at the following stages of installation.
• While the cable is still on the reel
• After installing heating cable
• After installation of thermal insulation
• Prior to connecting cable to power
• As part of a routine maintenance program
Applications . . .
1. Electric heat tracing cables are used for freeze protection2
and/or temperature maintenance of piping, tanks and
instrumentation.
2. Heat tracing cables may be installed in ordinary (nonclassified) and hazardous (classified) locations depending on
the specific cable options and approvals. See ‘Types of
Heating Cables’ on page 2.
2. Be sure all piping and equipment to be traced is completely
installed, pressure tested and painted (if applicable)
3. Surface areas where heat tracing is to be installed must be
reasonably clean. Remove dirt, rust and scale with a wire
brush and oil and grease films with a suitable solvent.
Receiving, Storing and Handling . . .
Initial Installation . . .
1. Identify the heating cable to ensure the proper type and
quantity have been received. The cable model number
will be visible on parallel heating cables (on braided
cables, the information is printed on the jacket below the
braid); factory-fabricated series circuits will have an imprinted l.D. tag with pertinent data. Compare information
on heating cable with packing slip and purchase order to
verify receipt of correct shipment. For date of production,
contact Thermon.
1. Begin temporary installation at the proposed end-ofcircuit location and lay out heating circuit on the pipe,
allowing extra cable for the power connection and for
any splice locations3. Refer to Illustration B for temporary
installation.
2. Make heating cable allowances for valves, flanges, elbows
and supports as per the applicable drawings, refer to
pages 4 and 5 of these installation procedures.
2. Visually inspect materials for damage incurred during
shipment. Report damages to the carrier for settlement.
Notes . . .
1. Termination kits to fabricate heat tracing circuits are not addressed in these
installation procedures. Refer to the specific installation instructions included
with the kits.
3. Store in a dry place. Keep ends of heating cable dry and
sealed before and during installation
2. For foundation heating, see installation instructions Form 10A081.
3. Minimum bending radius of heating cable is 32 mm (except HPT is 57 mm,
FP is 19 mm, TESH is 5 x OD).
Caution: Do not connect power to heating
cable while it is still on the reel or in a
shipping carton.

5. INSTALLATION PROCEDURES
Installation on Elbows, Supports and Flanges . . .
3. Pipe Supports: of diameter > 2” require additional heating cable, allow two times the length of the pipe support
plus an additional 8 cm of heating cable. (In process temperature maintenance systems the pipe supports must be
isolated from the pipes. In winterizing systems, Thermon
highly recommends to isolate the pipe supports from the
pipes)
1. Install heating cable in accordance with Illustrations C, D
and E below. Secure heating cable to piping using attachment tape rated at the application temperature.
2. Elbows: Locate the cable on the outside radius of an
elbow to provide sufficient heat to compensate for the
added piping material. Secure the cable to the pipe on
each side of the elbow with attachment tape.
4. Flanges: Allow cable to be looped around pipe on each
side of and adjacent to the flange. Heating cable must
maintain contact with flange when bending around pipe
flanges to compensate for additional heat loss.
Caution: Do not use metal pipe straps or tie
wire to attach heating cable. Use approved
attachment tape only.

7. INSTALLATION PROCEDURES
Completing the Installation . . .
4. Install power connection kit in accordance to the detailed
installation instructions provided with the kit. Power connection kits are provided for pipe mounting or for wall
mounting.
1. Begin final cable attachment by securing the end-ofcircuit termination kit and working back toward the power
supply. Power connections, splice connections, and endof-circuit termination kits are specified for each type of
heat tracer — substitutions are not allowed.
• Flexible heating cables are to be installed using attachment tape rated at the application temperature. Circumferential bands of tape should be installed at maximum
30 cm intervals to keep the cable in proper contact with
the pipe. Refer to Table 2 below for the number of rolls
of attachment tape required based on the pipe diameter1.
5. While making the power connection kits, but before making the final connection to power, repeat the megger test.
The cable should be tested with a test voltage of at least
500 Vdc. However, for polymer insulated heating cables,
2500 Vdc is recommended. The minimum acceptable
level should not be less than 20 megohms.
6. For ambient controlled power, the heating circuit should
be connected directly to the switched power feed wiring.
• If applicable, refer to installation details provided with
the project drawings or contact Thermon for additional
information regarding installation.
7. For pipewall sensing thermostatic control, the heating circuit is to be connected in series with the control contacts
with a maximum load of 16A. The pipewall sensing thermostat may require more than one support point.
2. In addition to the circumferential tape requirements, a
continuous covering of aluminum foil tape may be required when:
• Spray or foam urethane2 thermal insulation will be
applied.
• Heat tracing nonmetallic piping.
• Design requirements dictate the use of aluminum tape
to improve heat transfer.
8. Secure temperature sensor (if required) to pipe utilizing
attachment tape. Locate temperature sensor as shown in
Illustration H.
Notes . . .
1. Table 2 assumes circumferential bands every 12” (30 cm) along the length of the
process piping.
3. Complete splice connections (if required) in accordance
with the installation instructions provided with the splice
kit.
2. Verify exposure temperature of heating cable versus curing temperature of insulation.
